Arq Changelog

What's new in Arq 7.26.9

Apr 1, 2024
  • Fixed Issues:
  • Fixed an issue where Arq would show a Google error 'unauthorized_client' instead of prompting to grant access.
  • When launched, Arq attempts to check whether OAuth tokens are valid, and prompts to grant access for any token that isn't valid.
  • Arq checks whether the authorized Google Cloud Storage OAuth token actually has access to the data, not just that it's a valid token, and prompts to grant access if not.

New in Arq 7.26.8 (Mar 27, 2024)

  • Fixed Issues:
  • Implemented a workaround for Google Cloud OAuth because of Google's changes to OAuth scope permissions which was causing "app is blocked" errors.
  • Fixed an issue which could cause some people to get "HMAC of agent response doesn't match expected" errors when opening Arq.
  • Fixed an issue where, if a backup was started and then immediately stopped, changed files wouldn't be backed up the next time a backup runs.
  • Fixed an issue where, when applying 'thinning' retention rules, Arq always kept the oldest backup record no matter the retention rules.

New in Arq 7.26.7 (Feb 27, 2024)

  • Removed defunct Amazon Drive from list of possible storage locations.
  • Added support for AWS Calgary region.
  • Changed menubar icon animation to go up and down instead of up only, in order to be less distracting.

New in Arq 7.26.6 (Jan 3, 2024)

  • Changes:
  • Changed Google Drive remove-item behavior from moving to trash back to permanently deleting due to multiple customer complaints of Google not freeing up quota.
  • Updated internal metadata version to match the Windows metadata addition (new reparse-point flag).

New in Arq 7.26.4 (Nov 29, 2023)

  • Fixed Issues:
  • Fixed an issue where Arq could incorrectly deactivate its license if registered as an Arq Pro endpoint.

New in Arq 7.26.3 (Nov 29, 2023)

  • Changes:
  • Fixed an issue where an in-progress backup record could be left behind when the backup finishes and no changes have been detected since the previous complete backup record.

New in Arq 7.26.1 (Oct 31, 2023)

  • Changes:
  • Implemented memory and CPU usage optimizations in ArqMonitor.

New in Arq 7.26 (Oct 20, 2023)

  • Modified Arq's collection of current WiFi network name to accommodate macOS Sonoma's changes to Location Services permissions and continue to support including/excluding specific WiFi networks.

New in Arq 7.25 (Oct 13, 2023)

  • Changes:
  • Added support for ap-southeast-4 and il-central-1 AWS regions.
  • Added 'Apply Retention Rules' menu item so you can apply the rules without doing a backup first.
  • Fixed Issues:
  • Fixed an issue which could cause Arq on macOS Sonoma to prompt for an "app password" when none was set.

New in Arq 7.24.4 (Oct 6, 2023)

  • Fixed Issues:
  • Simplified backup-record-thinning logic and simplified activity-log output for it.

New in Arq 7.24.2 (Sep 28, 2023)

  • Changes:
  • Added "thinning" settings to the backup plan settings.

New in Arq 7.24.1 (Sep 26, 2023)

  • Changes:
  • Modified the Add-S3-Compatible-Storage-Location function to allow manually entering the bucket name.
  • Added a workaround for Storj's S3 incompatibility (returning a 429 HTTP status code instead of 503 as S3 does).
  • Removed the "thinning" function from backup plans. Too many people found backup records were permanently deleted that they weren't expecting to be deleted, and that's a really bad user experience, so we felt it was best to remove the function. As an alternative to limit the amount of storage used by your backup plan, edit the plan, click the Retention tab, check 'Limit storage used' and enter a value.
  • Changed "Delete..." button label to "Delete Backup Record..." to make it clearer what the button does; also added a confirmation dialog with a reminder that the action is permanent and cannot be undone.
  • Fixed Issues:
  • Fixed an issue where, When adding Google Drive as a storage location, if a permission error occurs when querying for a list of shared drives, Arq returns an error instead of ignoring.

New in Arq 7.24 (Sep 10, 2023)

  • New Features:
  • Added support for backing up to a shared drive in Google Drive.
  • Added support for backing up to any folder in Google Drive instead of only 'Arq Backup Data'.
  • Fixed Issues:
  • Fixed an Arq Pro issue where an app password was set in Arq but shown as not set in the web console.

  • Changes:
  • Changed ArqMonitor to show a notification every 8 hours if it can't connect to ArqAgent.
  • Changed timeout for most transactions to storage locations from 20 minutes to 3 minutes.
  • Retry on the very rare AWS 400 error 'Your socket connection to the server was not read from or written to within the timeout period. Idle connections will be closed.'
  • Retry continually on 'The network connection was lost' error, unless the user clicks 'Stop'.
  • Fixed Issues:
  • Fixed an Arq Pro issue where initialization may not have created the right files in the case of a backup set that's migrated from an older version of Arq.

New in Arq 7.22 (Aug 20, 2023)

  • Fixed Issues:
  • Fixed an issue which could cause Arq to start, stop, then start the backup plan unnecessarily on the next run after modifications to the backup plan.
  • Fixed an issue which could cause Arq Agent to crash on startup when encountering unexpected configuration files.
  • Fixed an issue which could cause Arq Pro sync to fail when the computer is first added to a group.

New in Arq 7.21.3 (May 9, 2023)

  • Fixed Issues:
  • Fixed an issue which could cause a "missing backupfolders.json" error if an Arq5-created backup set was adopted, edited, and then a new backup was run.
  • When restoring a single file, create the file without its parent directories.
  • Fixed an issue which caused an "authorization header is malformed" error when adding an S3 storage location.

New in Arq 7.21 (Apr 26, 2023)

  • Improvements:
  • Added a backup plan option so you can specify whether to report, ignore, or materialize dataless ("cloud-only") files such as Dropbox and Google Drive files.
  • Added Import and Export buttons for a backup plan's file selections.
  • Modified the behavior of the backup plan's "also start backup when a volume is connected" option to also start when the backup plan's storage location is an external drive and that drive is connected to the computer.
  • Added support for new AWS regions.
  • Added "Use Dual-Stack AWS Endpoint" checkbox for AWS storage locations.
  • Added support for Arq Pro.
  • Added a workaround for Google's new "Quota exceeded for quota metric 'Queries'" error.
  • Don't allow entering network-volume paths with trailing slash.
  • When restoring a folder containing "deleted" items (because "keep deleted files in subsequent backup records" option was checked in the backup plan, don't restore those "deleted" items. "Deleted" items can still be individually restored.
  • If unable to connect to ArqAgent, show a message about enabling "PhotoMinds LLC" background item (Apple hasn't updated the name yet).
  • When user deletes a backup set, select the delete Activity in the main window. Update the count of files while the activity is progressing.
  • When adding a B2 storage location and user chooses an existing bucket, show an error if bucket's lifecycle policy isn't 'keep only last version'.
  • When loading backup sets, if a backup set is missing items, show it anyway (with an error message) so that the user can select it and delete it.
  • Fixed Issues:
  • Fixed an issue which could cause "error -34018" when setting an app password.
  • Fixed an issue which prevented single-file backups created by Arq 5 from being restored correctly.
  • Retry on AWS 503 errors.
  • Changed 'thinning' algorithm to use GMT time zone to avoid potential issues when switching to/from daylight savings time.

New in Arq 7.19.11 (Jan 11, 2023)

  • Improvements:
  • Added safeguards to prevent deletion of the wrong backup records when applying retention rules.
  • Fixed Issues:
  • Fixed an issue which could cause Arq to report an error when browsing an unencrypted backup set created by Arq 6.

New in Arq 7.19.10 (Jan 11, 2023)

  • Fixed Issues:
  • Fixed an issue which could cause "EOF after 0 of 1 bytes received" errors when backing up a user-mounted volume with Arq 7.19.9.

New in Arq 7.19.9 (Dec 21, 2022)

  • Updates:
  • Added a workaround for macOS Ventura change that randomly results in "Interrupted system call" errors when retriving the file names in a directory.
  • Added a default for new backup plans that excludes ~/Library/Biome, the macOS suggestions database.
  • Updated libssh2 to 1.10.0 which adds support for more key exchange algorithms.

New in Arq 7.19.8 (Oct 20, 2022)

  • Fixed Issues:
  • Fixed an issue which could cause "HMACSHA256 of encryption dat file does not match" errors when attempting to browse backup records created by Arq 5 in a backup set that's also being used by Arq 7.

New in Arq 7.19.7 (Oct 16, 2022)

  • Updates:
  • Added a workaround to support S3-compatible storage locations (e2, Minio) with object lock which return non-standard error codes when attempting to delete a locked object, causing Arq to report an error for an action which isn't actually an error.

New in Arq 7.19.6 (Oct 2, 2022)

  • Updates:
  • Updated Google OAuth authorization process to comply with Google's policy change deprecating the OAuth "out-of-band" flow.
  • Store the key derived from the "app password" instead of the actual app password. This protects against malware running as root potentially stealing the app password, which a user might reuse elsewhere.
  • Return a better error message from B2 when a file is not found instead of B2's generic "file with such name does not exist" message.
  • Show a different UI for granting full disk access when installed on macOS Ventura.

New in Arq 7.19.5 (Sep 15, 2022)

  • Fixed Issues:
  • Fixed an issue where browsing backup data originally created by Arq 5 and never used by Arq 7 can return an error "no encryption password found in keychain for backup plan" when it should prompt for an encryption password.

New in Arq 7.19.4 (Sep 8, 2022)

  • Fixed Issues:
  • Fixed an issue where browsing an unencrypted backup set could produce an error "encryptedkeyset.dat not found".

New in Arq 7.19.3 (Sep 6, 2022)

  • Fixed Issues:
  • When backing up to an SFTP server, retry up to 5 times rather than retrying for up to 60 seconds, to ensure that Arq retries in the case of a timeout.
  • Instead of storing the backup plan encryption password (accessible only by root), store the encryption key derived from it (accessible only by root). This protects against malware running as root potentially stealing the encryption password, which a user might reuse elsewhere, thus potentially giving an attacker access to data beyond that legitimately needed for Arq's normal operation. This addresses CVE-2022-36617 filed by Sam Haskins.

New in Arq 7.19.2 (Jun 15, 2022)

  • New Features:
  • Added support for Wasabi Singapore ap-southeast-1 region.

  • Added support for new Wasabi Sydney region.
  • Added support for GovCloud as an S3-compatible storage location.
  • Sort the list of backup plans by computer name and backup name.

  • Prevent sleep during restore operations.
  • Fixed Issues:
  • Fixed an issue that could Arq's license information to get corrupted, resulting in Arq prompting for a license code.
  • Fixed an issue in the select-network-interface dialog (in the backup plan settings) where the wrong interface could be added to the list (not the one selected by the user).
  • Fixed an issue where Arq Agent might not start a scheduled backup on time.
  • Added support for using a symlink to a directory as the path when adding an SFTP storage location.
  • Fixed an issue where the "Uninstall" menu item would fail if there were issues initializing Arq Agent.

  • Added Storj as a storage location type.
  • Fixed Issues:
  • Fixed an issue where, if the user manually deletes the latest backup record, full file scanning may not occur at the next backup time.

New in Arq 7.18.1 (Mar 31, 2022)

  • Fixed Issues:
  • Retry if a transient SSL or networking error occurs when updating Arq Cloud about a completed backup (for Arq Premium subscribers only).

New in Arq 7.18 (Mar 30, 2022)

  • Fixed Issues:
  • Fixed an issue where auto-update would download and install an update that wasn't included with your license's updates. Arq 7.18 will accept all Arq 7 licenses regardless of updates-end-date in order to work around this issue for people who experienced it. If you experienced this issue and worked around it by purchasing a renewal that you didn't want to purchase, please email us at [email protected] and we'll promptly refund your renewal purchase.

New in Arq 7.17 (Mar 29, 2022)

  • Added support for Wasabi Toronto (ca-central-1) region.

New in Arq 7.16 (Mar 23, 2022)

  • Fixed Issues:
  • Fixed an issue where, if the user clicked 'Check for Updates', Arq 7.15.1 would say incorrectly that an update was available when in fact the update was not included with the license.

New in Arq 7.15.1 (Mar 22, 2022)

  • Fixed Issues:
  • Accept all Arq 7 licenses regardless of updates-end-date in order to avoid issues with people who had an Arq version older than 7.13 and subsequently turned on auto-update and received a version newer than their license's updates-end-date. All versions of Arq prior to 7.15.1 will update to 7.15.1. Arq 7.15.1 and future versions will update to the latest version available unless it's newer than the license's updates-end-date.

New in Arq 7.15 (Mar 15, 2022)

  • New Features:
  • Added support for Wasabi eu-central-2 region.
  • Added 'arqc' command-line utility for activating and deactivating license code, starting and stopping backup plans and retrieving status and activity log.

New in Arq 7.14 (Feb 15, 2022)

  • New Features:
  • Added support for Wasabi eu-west-2 region.
  • Fixed Issues:
  • Truncate activity log text in email reports to avoid unreasonably large emails.

New in Arq 7.13.4 (Jan 31, 2022)

  • Fixed Issues:
  • Fixed a license activation issue for some customers.
  • Fixed an issue that could cause a 'missing date in license data' error for lifetime license customers.
  • Changed the backup plan editor to allow editing of a backup folder's settings even when the volume is not connected.

New in Arq 7.13.3 (Jan 28, 2022)

  • Fixed Issues:
  • Fixed a license activation issue for some customers.

  • Show a more useful error message 'Cloud file contents not present on disk' when maOS returns 'Resource deadlock avoided' for contents-not-present type files.
  • Fixed Issues:
  • Fixed an issue with the display of updates end date in Arq's preferences.
  • Fixed an issue that could cause multiple dialogs to appear when an error occurs during search.

New in Arq 7.12 (Dec 19, 2021)

  • Changes:
  • Changed Arq's behavior regarding unknown objects found when adopting backup sets (or upgrading from Arq 5). On first backup after adopting a backup set, Arq will initialize its database from existing data as much as possible; it will reuse objects as much as it can and leav the remaining objects alone. The "Remove Unreferenced Data" function will delete all unreferenced data, including objects found during initialization that weren't referenced by any backup record that Arq was successfully able to read during initialization. This resolves the scenario where, with Arq 5, the user may have deleted backup records but not executed Arq 5's "Remove Unreferenced Data" function.
  • Retry on HTTP 408 errors.
  • Changed the retention behavior: When applying retention rules after backup, Arq now writes to the activity log every backup record date/time and whether it was kept or deleted.
  • Fixed Issues:
  • Fixed a bug that could cause a crash when clicking "Create Backup Plan" with no storage locations configured (which causes the add-storage-location dialog to appear) and then clicking Cancel on the add-storage-location dialog.

New in Arq 7.11 (Dec 2, 2021)

  • Fixed Issues:
  • Fixed an issue where Arq would report an error for an SFTP storage location where the path is a symlink to a directory (instead of a regular directory).
  • Fixed an issue where, when browsing Arq 5 data, if you enter an incorrrect password, Arq returns an error message instead of prompting a second time for an encryption password.
  • Fixed an issue where Arq could initialize its database from existing backup records, find errors, and report errors for the wrong backup recorsd.

New in Arq 7.10.1 (Nov 29, 2021)

  • Improvements:
  • Fixed an issue where, if an APFS volume is unmounted, Arq can give "volume not mounted" errors during subsequent backups of volumes on the same device until ArqAgent restarts.
  • If Arq fails to establish an SSL session with a Microsoft OneDrive/SharePoint server, retry a few times before giving up, to work around seeming configuration issues on Microsoft's end.
  • Fixed an issue where Arq may not prevent sleep when the prevent-sleep-during-backup option is checked in the backup plan.

New in Arq 7.10 (Nov 18, 2021)

  • Improvements:
  • Added support for Wasabi eu-west-1 (London) region.

  • Fixed issues with applying retention settings.
  • Removed a workaround that was causing Arq to retry on erroneous Amazon Drive 400 errors (which Amazon Drive seems to have stopped sending).
  • If "skip items excluded by Time Machine" option is checked, exclude .Trash and .Trashes, which seem to be hard-coded Time Machine exclude rules.

New in Arq 7.9.2 (Nov 7, 2021)

  • Improvements:
  • Added a workaround for Amazon Drive's inconsistency in showing accurate directory contents for just-created directories.

New in Arq 7.9.1 (Nov 7, 2021)

  • Improvements:
  • Added support for Wasabi ap-northeast-2 region.
  • On agent startup, configure Arq's cache directory to be excluded from Time Machine backups.
  • Updated pricing FAQ in the help to clarify operating system support.
  • Prompt for a storage class when creating an all-drives or all-user-data backup plan on AWS, instead of defaulting to Standard.
  • Suppoort adopting a backup set that was copied from a non-object-lock bucket to an object-lock bucket by resetting the backup set's bucket-versioning-is-on flag.
  • During restore, if Arq encounters data that Arq expects as readable but the user has modified to be Glacier or Deep Archive, request that objects be made downloadable.
  • Fixed Issues:
  • Fixed an issue where the configured transfer-rate limit wasn't always used when backing up to SFTP.

New in Arq 7.8.2 (Sep 27, 2021)

  • Fixed Issues:
  • Fixed an issue that could cause 'expired_auth_token' errors when backing up to B2

New in Arq 7.8 (Sep 21, 2021)

  • Fixed Issues:
  • Fixed an issue which could cause not-found errors when reusing backup data originally creatd by Arq 3 and stored in Glacier, and then adopted by Arq 5 and then Arq 6 and then Arq 7.
  • At backup start, check whether computer is on an allowed network before trying to connect to the storage location, to avoid unnecessary error reports.
  • Updated app icon to a squircle similar to current Apple icons.

New in Arq 7.7.2 (Aug 17, 2021)

  • Fixed Issues:
  • Fixed an issue that could cause "PATCH HTTP error 500" errors when encountering multiple folders with the same name in the same folder in Google Drive.

New in Arq 7.7.1 (Aug 11, 2021)

New in Arq 7.7 (Aug 10, 2021)

  • Improvements:
  • Added a tooltip over the "Modified" column that describes which values have changed.
  • Show 'Last Changed' column in backup record detail view to indicate metadata (not file contents) have changed.
  • Modified APFS snapshot usage to prevent other processes from unmounting Arq's snapshot during backup.
  • Changed activity log and email report to show more readable numbers like "5 MB" instead of "5,234,221 bytes".
  • Added details to the documentation for immutable backups and thinning.
  • In the edit-SFTP-storage-location dialog, edit the path as well.
  • Fixed Issues:
  • Fixed an issue which could cause 'missing error information' errors during cleanup.
  • Fixed an issue where the 'show hidden files' checkbox wasn't taking effect on subdirectories when directories are expanded.
  • Fixed an issue that could cause occasional upload errors to Arq Cloud storage.
  • Fixed an issue that could cause a crash when saving a backup plan on macOS 10.11.

New in Arq 7.5.16 (Jun 9, 2021)

  • Fixed Issues:
  • Fixed an issue that could cause 'Error creating cloud account' for some users.
  • Do not log an error when backing up an empty folder.
  • Fixed an issue where, if a backup plan's options include a restricted list of WiFi networks, the allowed-network check failed because the computer had just woken up and WiFi was the active network interface but not connected to a network yet.
  • Fixed an issue where OneDrive aborted a file-upload session and Arq reported it as an error instead of retrying.

New in Arq 7.5.13 (Jun 2, 2021)

  • Fixed Issues:

  • Fixed an issue where, if you changed the backup plan's name, the "blob identifier type" was being reset to SHA256 for the backup plan. If it was originally SHA1 (e.g. for a backup plan upgraded from Arq 5) this could cause re-uploading of data.
  • Fixed an issue where restoring from an Arq 6 snapshot stored in Glacier or Deep Archive may not request all needed objects be made "downloadable", causing Arq to wait forever to restore data.
  • Changed the assertion used by the prevent-computer-sleep function to prevent sleep when the computer's lid is closed.

  • Fixed an issue where ArqMonitor could return an authentication error after user sets app password in Arq.
  • Fixed an issue where, for all-drives backup plans, Arq wouldn't always match up disk identifiers with existing backup records, resulting in more than 1 folder of backup records.

  • If the volume disappears during backup, Arq won't save the new backup record that doesn't have all files. It will leave the in-progress backup record.
  • Fixed an issue where Arq didn't find a file during restore from another computer's backups if it had cached the list of files and the other computer had subsequently added files.

New in Arq 5.2.5 (Sep 23, 2016)

  • Fixed issues:
  • Fixed an issue which caused Google Drive backups to fail with 'removeItemById not implemented' errors.

New in Arq 5.2.2 (Aug 31, 2016)

  • Fixed Issues:
  • Added a workaround for Amazon Cloud Drive problems which result in random HTTP 400 and 408 errors.
  • On backup start, wait up to 30 seconds for an allowed network before failing with an error. This allows for a computer that just woke up to establish network connectivity.
  • If Arq is unable to write a README.TXT file in the user's Google Drive account because the quota has been exceeded, ignore the error so that the user can add the Google Drive destination in Arq and then be able to use Arq to delete the "hidden" data (if the user chose to use the hidden "appdata" folder when configuring Arq).
  • Fixed an issue where Arq would not show another computer's backup set added later because it used cached data instead of requerying for the current list of backup sets.
  • Fixed a database issue which could cause Arq to spend a very long time on a database query for very large (multi-terabyte) backup datasets.
  • Fixed an issue which could cause log files to prematurely rotate. Arq, Arq Agent and helper programs will now write 100 MB log files, keeping up to 10 files.
  • Removed "wl.basic" from the list of OneDrive permissions requested by Arq, because Arq doesn't need it.

New in Arq 5.2.1 (Aug 21, 2016)

  • Fixed Issues:

New in Arq 5.2 (Aug 9, 2016)

  • Improvements:
  • The data validation process now goes beyond verifying the existence of all needed objects at the destination; it now verifies that the contents of the objects at the destination are correct.

  • If user has chosen specific network interfaces and current network interface can't be determined, do not back up.
  • When deleting a Dropbox folder, recursively delete the contents first to work around a Dropbox issue.
  • If backing up to a local folder, skip checking whether we're on an allowed network.

  • Fixed issues:
  • Made data validation optional, via a checkbox in the destination preferences.
  • Changed Arq Agent to wait 2 minutes between finishing a backup and starting data validation, to avoid "eventual consistency" issues (delays in getting accurate file lists from Amazon Cloud Drive and other providers).
  • Fixed an issue where, during data validation, Arq Agent wasn't properly checking for a running Arq process and aborting if it found one.

New in Arq 5.0.9 (May 3, 2016)

  • Fixed an issue where, if a backup session aborts with an in-progress backup record, some files may not get backed up.

New in Arq 5.0.8 (May 3, 2016)

  • Fixed an issue that could cause 'Older backups missing' errors due to cache problems.

New in Arq 5.0.7 (Apr 29, 2016)

  • Fixed issues:
  • Arq now runs the "preflight" script before checking whether the destination (local path or otherwise) exists.
  • Fixed a potential bug in the way Arq detects file/directory changes.
  • If you add an AWS destination using an IAM user with a very restrictive IAM policy, Arq can't get the list of buckets but you can type the existing bucket's name into the "create bucket" field. Arq will not throw an error if the bucket already exists and is owned by you.
  • Fixed an issue where Arq would show an "HMACSHA256 doesn't match" error instead of prompting for the backup set's encryption password.
  • Fixed an issue where the OK button for the Edit Backup Selections window didn't work for OS X versions older than 10.10.

  • Fixed Issues:
  • Read OneDrive folder listings page by page to work around timeout problems with OneDrive's API.
  • Added a workaround for a problem when trashing an Amazon Drive file. If Amazon gives a 500 error and Arq retries, sometimes the file was actually trashed and Amazon returns an undocumented 409 error. Arq now catches that and moves on.

New in Arq 4.14.4 (Aug 21, 2015)

  • Fixed Issues:
  • Added a workaround for Amazon Drive. Amazon Drive sometimes doesn't return a full list of items in a directory (when a 500 error occurs during paging through the listing), causing Arq to fail to load backup records. Arq now compares the actual total item count received to the expected total; if it didn't get all the items, it retries until it does.

  • Fixed an issue with Amazon Cloud Drive caching which can cause "error " errors.

New in Arq 4.14 (Aug 17, 2015)

  • New Features:
  • "Thinning" backups (keeping hourly backups for the past 24 hours, daily backups for the past month, and weekly backups after that) is now optional. Check "Thin backups" in Arq's preferences to enable it.
  • New users will now be prompted to select bucket name and region if choosing AWS or Google Cloud Storage.
  • Fixed Issues:
  • If duplicate items with the same name in the same folder in Google Drive are found, keep the newest one.
  • Added a workaround to detect and merge duplicate items in Google Drive.
  • Fixed an issue where Arq wasn't prompting to re-authorize if Amazon Cloud Drive access was revoked.
  • Fixed an issue where cached Google Drive data would cause not-found errors when removing and re-adding Google Drive as a destination.
  • Fixed an issue where the status message from the agent wasn't always being sent to the Arq app.
  • Stopped excessive logging of Amazon Cloud Drive folder results when log level is set to Debug.

  • If AWS returns invalid XML when Arq is searching for backup sets to restore from, skip the problem data.
  • Fixed an issue where Arq could potentially create 2 Google Drive directories with the same name at the same location (because, weirdly, Google Drive's API allows that).
  • Fixed an issue where Arq would crash after clicking the Close button when viewing Glacier restore errors.
  • Fixed an issue where Arq could crash while loading folder lists when multiple Google Drive destinations are configured.
  • Changed Google Drive implementation from delete-and-insert to update to work around a bug in Google Drive where it says it deleted a file but it didn't actually delete the file.

New in Arq 4.12 (Jun 22, 2015)

  • New Features:

  • Removed the check for free space on SFTP server because most SFTP servers don't support the API call.

New in Arq 4.9.1 (Feb 26, 2015)

  • New Features:
  • Added "archiving" feature: Select a folder and click "Detach"; Arq will skip that folder during backup, but its backup records will remain at the destination.
  • Fixed Bugs:
  • Fixed an issue when attempting to read contents of a non-existent Dropbox directory that caused Arq to behave like you were typing in the wrong encryption password when restoring.
  • If Dropbox returns a 429 (rate-limiting) error during backup, sleep and try again. (The main UI will show the error instead of retrying, so that it doesn't seem to hang forever.)
  • Migrate Arq data in Dropbox from 2-directory structure to single directory structure because if the object-list cache file goes missing, it takes way too long to read the contents of potentially 65,536 directories.

New in Arq 4.9 (Feb 25, 2015)

  • New Features:
  • Added "archiving" feature: Select a folder and click "Detach"; Arq will skip that folder during backup, but its backup records will remain at the destination.

  • Added support for new AWS Frankfurt region.
  • Added a button to delete all Arq-created data from your Google Drive account.
  • Switched to AWS Signature Version 4 for signing AWS requests.
  • Changed the default to not use the hidden "appdata" folder when adding a Google Drive account because it was causing too much confusion. While it's nice to store data in the "appdata" folder so that it doesn't clutter your Google Drive activity view, it's difficult to see or delete that data when you need to.
  • Fixed Bugs:
  • Fixed an issue on OS X Yosemite where errors would get the description 'Operation could not be completed' instead of the actual error message.
  • If the user tries to add a folder for backup to Google Drive and Arq's Google Drive access has been revoked, offer to let the user grant access instead of just showing an error.

New in Arq 4.6.2 (Oct 21, 2014)

  • Fixed Bugs:
  • Fixed an issue where the backup process aborted if there's an error creating an FSRef on OS X Yosemite (because it's not a valid file for creating an FSRef).

New in Arq 4.6.1 (Oct 20, 2014)

  • Fixed Bugs:
  • Updated menubar icon to work in Yosemite "dark menu bar".
  • If extra whitespace was copied/pasted into AWS key fields, it's removed automatically.

New in Arq 4.6 (Oct 17, 2014)

  • New Features:
  • If agent is configured to check for app updates, agent will show a user notification when an update is available.
  • Added a "Remove Unreferenced Objects Now" menu item to the agent's menu which causes Arq to immediately clean up any objects at the destination that aren't referenced by any backup records.
  • Added a quota check for Google Drive so that Arq stops backing up if Google Drive usage is within 1.5GB of the user's quota.
  • Fixed Bugs:
  • Fixed a bug where, if you don't know the encryption password and attempt to delete a backup set anyway, it was failing with a bad-decrypt error.
  • Changed the max-keys parameter for Amazon list-objects requests to 500 to try to avoid an Amazon issue of garbling XML output.
  • If password verification fails when user is trying to delete a backup set, offer to delete it anyway, because the user has permission to modify/delete the data, and it could be incomplete data. For example, if the user disconnected Arq from her Google Drive account and Google deleted some of the data and then the user reconnected Arq for the purpose of deleting the backup set, the password verification might fail.
  • Fixed an issue where Arq wasn't properly detecting a Google Drive "Rate Limit Exceeded" error and retrying.
  • Log XML data when an XML parse error occurs.

New in Arq 4.5.5 (Sep 12, 2014)

  • Fixed Bugs:
  • Fixed an issue where unexpected JSON from Google Drive resulted in Arq thinking objects were much larger than they actually were, which could result in the budget-enforcement process deleting more backup records than it should.
  • Fixed an issue where, after data validation, if there was no budget set Arq would not delete unreferenced objects.
  • Fixed an issue with restoring "locked" files that resulted in Arq reporting an "Access to this item was denied" error.

New in Arq 4.5.4 (Aug 20, 2014)

  • Fixed the 'absurd string length' error caused by an index file with incorrect offsets in it. Arq will recreate the index file from the pack data, and replace the bogus index file.

New in Arq 4.5.3 (Aug 13, 2014)

  • Fixed Bugs:
  • Fixed an issue with Google Drive where Arq would occasionally crash when adding Google Drive as a destination.

New in Arq 4.5.2 (Aug 12, 2014)

  • Fixed Bugs:
  • Fixed an issue with Google Drive where Arq would erroneously try to create the 'appdata' folder, a special folder which always exists.

New in Arq 4.5.1 (Aug 12, 2014)

  • Fixed Bugs:
  • Changed Google Drive scope to avoid intermittent access-denied errors from the Google Drive API.

New in Arq 4.5 (Aug 11, 2014)

  • New Features:
  • Support for backing up to your own Google Drive storage!
  • Improvements:
  • During Glacier restore, show messages like 'Waiting for objects to become downloadable' to give a better indication of what's happening while Arq waits for Glacier.
  • Added help bubbles during initial setup to show what is being backed up and where the Arq Agent menubar icon is.
  • Reduced the number of prompts during the initial setup.
  • Fixed Bugs:
  • Fixed an issue where Arq incorrectly treats non-AWS destination data as Glacier data.
  • Fixed the 'error making FSRef for /dev' error.
  • Fixed an issue where Arq was storing SFTP data in too many subdirectories resulting in very slow object-list retrieval during data validation and budget enforcement.
  • Fixed an issue where the RESTORE FILES section wasn't showing Greenqloud backups from other buckets.
  • Fixed an issue where SFTP destinations created by previous versions of Arq had a double-slash in the path.
  • Fixed an issue where Arq failed to back up to SFTP servers that behave badly (not giving not-found errors when Arq tries to read a file that doesn't exist).
  • Stop shifting keyboard focus to the backup record when the user selects a backup record in the source list.
  • If you attempt to submit feedback and an error occurs, the feedback window doesn't close and your input is not lost.
  • Removed the 'S3' text in the size calculations for non-S3 destinations.

New in Arq 4.4.1 (Jun 28, 2014)

  • Fixed Bugs:
  • Fixed an SFTP issue where, if you supply a relative path and your home directory on the SFTP server is "/", the path ended up being "//relativepath" which caused backup errors.
  • Fixed the "Delete This Backup Set" button.
  • Show the "Trash" folder for deleted legacy Glacier folders.
  • Fixed a "hostname could not be found" error for EU buckets caused by Amazon changing their loation identifier from "EU" to "eu-west-1".
  • Fixed an issue where the legacy Glacier vault was still shown in the window after you clicked the button to delete it.
  • Fixed a 10.7-only issue with Google Cloud Storage where the generated Date header was not in a format that Google accepted.
  • For backups to DreamObjects, handle the non-AWS-format error response when DreamObjects returns a 500 error.
  • Added a permission to the restricted IAM user that Arq creates so that that user can list enough of the bucket to find its own backups.

New in Arq 4.4 (Jun 20, 2014)

  • Improvements:
  • Reorganized the main window into "Configure Backups" and "Restore Files" sections to more closely match the activities that a user would typically want to do.
  • Revamped the new-user flow so that it's more clear what to do -- either set up backups or restore files.
  • Under the "Restore Files" section, search for and show all the backup sets in the Amazon account (or SFTP directory or S3-compatible account), so that it's easier to find your old backups when you install Arq on a new computer..
  • Rewrote, updated and expanded the help documentation.
  • If you try to quit Arq after defining a destination but not configuring anything to back up to that destination, Arq warns you and offers to back up your home folder.
  • Moved the (legacy) Glacier vaults into a separate window. Pick "Legacy Glacier Vaults" from the menu to get a list, check each one for corresponding Arq metadata, and delete it if desired.
  • Added a delete-individual-backup-record function. Select a backup record to view it; then click the Delete button on the top right to delete just that backup record.

New in Arq 4.3.1 (Jun 16, 2014)

  • Fixed Bugs:
  • Fixed an issue where, during first-time setup, the S3 bucket wasn't always created.

New in Arq 4.3 (Jun 10, 2014)

  • Improvements:
  • Simplified the first-time setup of Arq by choosing sensible defaults (which can be changed later by the user).
  • Added "Add Home Folder to Backups" menu item which adds the home folder with standard exclusions.
  • Improved CPU efficiency during validation.
  • Show small file sizes as 'n bytes' instead of '0.0KB'.
  • Fixed Bugs:
  • Fixed "No S3 bucket name give" error.
  • Fixed a crash that occurs during some SFTP connection errors.

New in Arq 4.2.3 (May 15, 2014)

  • Fixed Bugs:
  • Fixed a bug where the validation code was checking the wrong return value, eventually resulting in a "Tree may not be 0 bytes" error message.
  • Fixed an issue where the validation code was doing excessive checking of object-existence at the target causing slow performance.

New in Arq 4.2.2 (May 9, 2014)

  • Fixed Bugs:
  • Fixed an issue which caused a "must be S3 or S3Glacier" crash during validation.
  • Fixed an issue where enforcement error returns a "null" error message instead of the actual message.
  • Fixed an issue which returned a "pack index data length 0 is smaller than size of pack_index" error.
  • On launch after update, if run-as-root was set previously, prompt the user to re-add run-as-root permissions to the new update.
  • Fixed an issue where, if you choose "back up home folder minus caches and logs" it still backs up caches and logs.

New in Arq 4.2.1 (May 3, 2014)

  • Fixed Bugs:
  • Fixed object-not-found issues in restoring from a Glacier folder that was originally backed up with Arq 3 and subsequently backed up with Arq 4.
  • Fixed an issue that could potentially mistakenly delete S3 Glacier-storage-class objects needed by Arq3-created Glacier backups.

New in Arq 4.2 (Apr 30, 2014)

  • New Features:
  • Allow relative path or no path for SFTP targets. Arq figures out the absolute path for you.
  • S3 and S3/Glacier totals are shown separately when you click "Calculate".
  • Fixed Bugs:
  • Don't allow more than 59 minutes after the hour in the target preferences.
  • Removed device ID from the backup file/folder info so because OS X randomly changes the device ID which was making all the files look modified in Arq.
  • Fixed an issue where files restored from another computer's backups were owned by root.
  • Fixed an issue where modification time wasn't being set properly on some restored files.
  • Fixed an issue where backup couldn't be stopped if it was in the midst of retrying to connect to an SFTP server.
  • Fixed an issue where Arq Agent would calculate storage totals even if budget wasn't enabled for the target.
  • Fixed an issue where the progress number in the status message shown in the main app wasn't in sync with the progress number shown below the progress bar.
  • Fixed an issue where the progress number displayed could incorrectly exceed the total number by a large margin.

New in Arq 4.1.7 (Apr 23, 2014)

  • Fixed Bugs:
  • Fixed an issue that caused Arq Agent's helper program to crash when a backup error occurs and no error information is available.
  • Removed unreliable "multi-threaded processing" option.

New in Arq 4.1.6 (Apr 23, 2014)

  • Fixed Bugs:
  • Fixed "unsupported URL" error when updating credentials for Google Cloud Storage target.
  • Fixed an issue where Arq could crash when expanding a folder "node" in the source list.
  • Eliminated redundant calls to "restore" a Glacier object that's already been requested for restore.
  • Eliminated redundant calls to check if a pack file is downloadable.
  • Added computer name to email report.
  • Retry SFTP backups on all transient errors (e.g. network not available).
  • Fixed an issue in SFTP validation that could cause Arq to delete objects from the server that it shouldn't be deleting.

New in Arq 4.1.5 (Apr 14, 2014)

  • Fixed Bugs:
  • Fixed an issue where Arq would ignore the port value if an S3-compatible server is configured with a non-standard port.

  • Fixed an issue where the restricted IAM user created by Arq could not list Glacier vaults and calculate total AWS storage.
  • Fixed erroneous "Not all Glacier vaults have been inventoried" message when calculating total AWS storage.

New in Arq 4.1.4 (Apr 4, 2014)

  • Fixed Bugs:
  • Fixed an issue where an error reading a pack file would cause the app to crash.
  • Fixed an issue where an invalid pack file would cause the app to crash.
  • Fixed an issue where an invalid pack index file would cause the app to crash.

New in Arq 4.1.3 (Apr 2, 2014)

  • Fixed Bugs:
  • Show a progress indicator in "View Items Being Backed Up" window when it's still loading data.
  • If backup prior to validation fails, don't immediately attempt to back up and validate again.
  • Retry when Amazon returns with "a conflicting conditional operation is currently in progress against this resource."
  • Fixed an issue where a not-found error caused the Calculate function to fail for SFTP targets.
  • Fixed an issue where a not-found error caused data validation to fail for SFTP targets.

New in Arq 4.1.2 (Mar 29, 2014)

New in Arq 4.0.2 (Mar 6, 2014)

  • Fixed Bugs:
  • If an encryption password is missing or incorrect, Arq will prompt for a new one.
  • If the secret key for a target is missing or incorrect, Arq will prompt for a new one.
  • Fixed an issue where GreenQloud credentials weren't being sent to the server properly in some cases.
  • Fixed issues where clicking "Go Back" from the select-bucket window didn't go back to the correct window.
  • Fixed an issue which caused an "absurd length requested" error during validation/budget enforcement.
  • Fixed an issue where Arq would exit on startup if unable to resolve an SFTP hostname.
  • Fixed an issue where Arq Agent would loop incessantly on startup if keychain entries were missing.
  • If a target's secret key/password is missing from the keychain, Arq prompts the user to re-enter it.
  • Show the target description in the error dialog if there's an error in Arq loading the target's folders.

New in Arq 4.0 (Mar 3, 2014)

  • Back up to AWS, GreenQloud, DreamObjects, Google Cloud Storage, or any other S3-compatible target.
  • Back up to any SFTP server.
  • Back up to multiple servers of different types, with different schedules and budgets.
  • Optionally back up only on selected wifi networks.
  • Optionally back up only during a specified window of time each day.
  • Optionally send email notification after backup.
  • Unified schedule and budget across S3 and Glacier backups.
  • New S3/Glacier option backs up to your S3 bucket but with a "bucket lifecycle policy" so that objects in the bucket are moved to Glacier storage class for cost savings. This eliminates the need for cumbersome Glacier vaults. Also Arq can get the object list, so it can do full de-duplication and budgeting of Glacier backups. (Old-style Glacier backups from Arq 3 are still supported but don't have budgeting or full de-duplication.)

New in Arq 4.0 Beta 17 (Feb 28, 2014)

  • Fixed Bugs:
  • Fixed one more bug that was causing "absurd string length" errors when validating data.
  • Add up both S3 and S3/Glacier totals when calculating storage size for AWS targets.
  • Fixed issues which caused last-enforcement dates to be set incorrectly and caused Arq Agent to validate data and enforce budget far too often.
  • Fixed an issue which caused validation of S3/Glacier objects to proceed very slowly.

New in Arq 4.0 Beta 16 (Feb 27, 2014)

  • Added Features:
  • Display last validation/enforcement time in target preferences view.
  • Remember the last value entered in the "pause" dialog.
  • Set validation/enforcement interval in days instead of hours.
  • Fixed an issue which caused an "invalid signature" error when restoring from Glacier.
  • Fixed an issue where clicking OK on a Glacier error message had no effect.

  • Fixed an issue which prevented SSL email sending for some SMTP servers.

New in Arq 4.0 Beta 15 (Feb 26, 2014)

  • Fixed Bugs:
  • Fixed an issue where the backup would fail with "The internet connection appears to be offline" instead of retrying.
  • Added a workaround for an issue with some broken SFTP servers which set file permissions when SFTP clients open them for reading.
  • Removed a file-reading optimization that was causing random errors that I couldn't reproduce.

New in Arq 4.0 Beta 12 (Feb 25, 2014)

  • Added Features:
  • Store the pause minutes as a default so that when the user pauses backups again, the previous value is the default.
  • Fixed Bugs:
  • Fixed major SFTP issue where occasionally not all bytes are written to the file on the SFTP server.
  • Fixed an SFTP performance issue where reading cached data was very slow.
  • Fixed a validation bug for SFTP which made validation extremely slow as it asked the server about the existence of every single object.
  • Fixed budget enforcement logic so that unreferenced objects are still deleted even when budget is not enabled.

New in Arq 4.0 Beta 11 (Feb 24, 2014)

  • Added Features:
  • Display more information about the target in several places in the app, making it easier to select the correct target in the "Back Up Now" window, for example.
  • Fixed Bugs:
  • Fixed an issue which caused repeated keychain permission prompts as you edited the SMTP password.
  • Fixed an issue which could cause Arq to crash when you're entering an email address for email reports.
  • Fixed an issue which caused Arq to prompt for target info when migrating from Arq 3. Now it properly uses the Arq 3 settings.
  • Updated the 'how to create AWS credentials' video.
  • If there's an error in the background thread reading the next chunk of file data, log the error immediately.
  • Fixed bugs in pausing and resuming and properly displaying the in-progress status or pause reason.
  • Fixed an issue that caused Arq to report successful backup when there was an error (or the backup was stopped by the user).

New in Arq 4.0 Beta 10 (Feb 24, 2014)

  • Fixed Bugs:
  • Fixed an issue that caused crash on launch on OS X 10.7.
  • Fixed an issue where the "Calculate" button was disabled.
  • Fixed an issue where cache files were being created with 'root' ownership when they should be owned by the logged-in user. This issue could cause Arq to get "stuck" trying to write a cache file to a directory owned by root.

New in Arq 4.0 Beta 9 (Feb 21, 2014)

  • Fixed Bugs:
  • Fixed a crash in arqcommitter when an error occurs during backup.

  • Fixed assorted other memory leaks.

New in Arq 4.0 Beta 7 (Feb 14, 2014)

  • Fixed Bugs:
  • Fixed an issue where changes to the budget weren't saved properly.
  • Fixed an issue where the user entered a relative path for SFTP when an absolute path is required.
  • Fixed a bug where choosing an existing bucket that begins with a number isn't allowed.

New in Arq 4.0 Beta 6 (Feb 12, 2014)

  • Added Features:
  • Show progress/total bytes in agent's menu.
  • Fixed Bugs:
  • Fixed the issue where you try to add a folder to backups but nothing happens.
  • Fixed the issue where you try to delete a Glacier vault and nothing happens.
  • Reduced memory consumption of arqcommitter helper program during backup.
  • Removed the pesky libssh2.dylib that's been causing so many crashes.

New in Arq 4.0 Beta 5 (Feb 12, 2014)

New in Arq 4.0 Beta 4 (Feb 11, 2014)

  • The beta will expire March 17, but Arq 4 should be shipping by then. If not, a new beta version will be available.
  • NEW STORAGE OPTIONS:
  • For the first time, Arq can back up to not just Amazon Web Services. You can choose GreenQloud, DreamObjects, Google Cloud Storage, or any other S3-compatible target.
  • You can even choose to back up to an SFTP server! If you have a NAS in your home or office that allows SSH/SFTP access, you can back up to that and pay $0 in monthly storage charges. Or back up to a VPS (virtual private server) like Dreamhost for cheap offsite backup.
  • MORE CONTROL:
  • Several new features are aimed at providing you with more control over your backups:
  • Backup only on selected wireless networks — prevent upload when tethered to your phone, for instance
  • Networks
  • Email notifications — great for monitoring headless/remote Macs and customer Macs
  • Email prefs
  • A unified budget across S3 and S3/Glacier backups (see “A New Approach to Glacier” below)
  • Optionally specify a “window” of time during the day/night when Arq pauses — useful for networks that are underutilized at night, and for ISPs that charge less at certain times of day
  • Backup window
  • OTHER FEATURES:
  • Arq 4 includes several other features and improvements, including a “Stop Backup” function, the display of the last backup date in the agent’s menu, and less prompting for administrator privileges when restoring. Also, the process for setting up and restoring to a new computer is more straightforward.
  • A NEW APPROACH TO GLACIER:
  • When Amazon announced their Glacier offering in the fall of 2012, we built Arq 3 to take advantage of it. Some time after Arq 3 was released, Amazon announced an S3 Glacier Lifecycle feature through which Amazon would automatically store certain S3 objects in Glacier. Arq 4 uses this new S3 Glacier Lifecycle feature for Glacier backups (existing Glacier backups made with Arq 3 will continue to use the old Glacier API as Amazon offers no way to move Glacier objects to S3).
  • There are several benefits to using the s3 glacier lifecycle feature:
  • S3 objects with Glacier storage class have all the benefits of regular S3 objects — a known location/name, S3 object query abilities
  • No more creating Glacier vaults, which are hard to use and even harder to delete.
  • Restored objects are at known/expected locations, unlike restored Glacier objects which receive a random name.
  • Restored objects can be persisted for much longer, unlike restored Glacier objects which have a fixed 24-hour expiration.
  • Restarting a restore with Arq means only requesting restore of objects which haven’t been requested yet because previously-requested objects are at known locations.
  • Restoring is less complex and much faster — no more creating SQS queues and SNS topics; no more taking the time to read all messages from the SQS queue before beginning to download.
  • Budgeting is possible using the same logic as the S3 budget feature.
  • CHANGING TO THE NEW S3/GLACIER FORMAT:
  • Unfortunately Amazon doesn’t provide a mechanism for creating “pointers” in S3 to existing Glacier objects, so if you want budgeting and easier restoring with Glacier, you’ll have to re-upload your files. I know this is far from ideal, but in the long term I believe it pays dividends in cost and ease of use.
  • Arq no longer restricts you from adding the same folder twice, or adding a folder contained by a folder that Arq is already backing up. So, if you’ve been backing up a folder to Glacier with Arq 3, just add the folder to Arq again, and choose “Glacier storage class”:
  • Arq will back up the folder to S3 in a subdirectory of your S3 bucket called “glacier” which Amazon will automatically archive to Glacier storage class (Arq creates the Glacier lifecycle policy automatically). When it’s done uploading, delete the old folder (the old-style Glacier backups created with Arq 3).

New in Arq 3.3.4 (Feb 4, 2014)

  • Fixed Bugs:
  • Reverted a change in 3.3.3 that resulted in excessive recalculation of encryption keys and excessive CPU usage.

New in Arq 3.3.3 (Jan 23, 2014)

  • Fixed Bugs:
  • Fixed an issue where Glacier seems to be returning fewer bytes than it promises in its Content-Length header when Arq queries for Glacier job output. Arq now retries until it gets all the bytes.
  • Instead of waiting for all the bytes of a file to be available from Glacier, start writing the file as soon as the first chunk is available. Otherwise, for very large (tens or hundreds of GBs) files, the chunks would start expiring from Glacier before Arq had a chance to download all of them.
  • Read up to 10 SQS messages (the max allowed by AWS) at a time, instead of 1 at a time.

New in Arq 3.3.2 (Dec 10, 2013)

  • Fixed Bugs:
  • Added backup set UUID to Glacier vault names to make restricting access via IAM easier.
  • To avoid the "missing x-amz-archive-id" errors, Arq checks for 408 response code whether or not the message body has a "RequestTimeoutException" code in it.
  • Skip any item named "//buckets/" or any other invalid XML plist with that prefix (to get around bogus files that apps like Jungle Disk may have placed there).

New in Arq 3.3.1 (Nov 14, 2013)

  • Fixed Bugs:
  • Fixed an issue where Glacier requests weren't being retried when they should have been.
  • Fixed an issue where the wrong dates were used in communicating with AWS when the calendar was set to Thai.
  • Changed the incomplete backup-record label from "(incomplete)" to "in progress").
  • Changed the multi-threaded get-object-list operation to single-threaded to remove any chance of synchronization errors that could result in an incomplete object list.
  • When validating objects in S3, if the object wasn't in the listing, execute a HEAD request against S3 to make sure it really isn't there before marking it as missing.
  • When validating objects in S3, if an object was marked missing but it's actually available in S3, remove the "missing" flag.

New in Arq 3.3 (Oct 16, 2013)

  • Fixed Bugs:
  • Added a 30-second timeout to HTTP/S requests to recover from bad connections.
  • Fixed an issue where some license keys wouldn't work with answer files.

New in Arq 3.2.5 (Aug 1, 2013)

  • Fixed Bugs:
  • Fixed an issue where, if an error occurred during an HTTP/S connection, the app would continue to try to use that connection (and become "stuck") instead of dropping it and creating a new one.
  • Fixed an issue where not all relevant Glacier vaults were being included when calculating total Glacier data size.

New in Arq 3.2.4 (Jul 2, 2013)

  • Fixed Bugs:
  • When user drags/drops an item to restore it, offer to overwrite the existing folder/file if one exists.
  • Fixed an issue where a not-yet-available error from Glacier causes Arq to skip downloading a file.
  • Retry when an AWS query request returns a 503 error.
  • Changed the status message to 'Comparing existing files to backup data' when checking existing files to determine which files we don't need to restore.
  • If pause is requested, abort uploading the current file, close the file descriptor (so the user can eject her external drive!) and start over on the file when resume is requested.

New in Arq 3.2.3 (Jun 24, 2013)

  • Fixed an issue with 2-pack and 10-pack Arq license files.

New in Arq 3.2.2 (Jun 24, 2013)

  • Fixed a timeout error when adding a folder to be backed up to Glacier.

New in Arq 3.2 (Jun 13, 2013)

  • New Features:
  • Restore into an existing folder of files, only downloading the files that are different or missing. Restore runs using administrator privileges to avoid permission issues. If you use SuperDuper or similar to clone your system periodically, in the event of a disk failure you could recover using the SuperDuper clone and then restore from Arq to update the missing/out-of-date files and avoid downloading everything from AWS!
  • Added a "pause on battery power" feature -- set it in Arq's preferences.
  • Added a "setthrottle" command-line option to change the transfer rate setting. This is useful for those who wish to change Arq's throttle setting via a script.
  • Fixed Bugs:
  • Fixed an issue during very large Glacier restores where Arq would request too many items, which would then expire from AWS before Arq got a chance to download them.
  • Improved memory usage and performance during Glacier restore.
  • Fixed 10.6-related crashes.
  • Fixed broken throttling issue.
  • When calculating AWS usage for this computer, only include Glacier vaults that belong to this computer's backups.
  • If you pause backups, Arq will pause after it finishes uploading the current file, not in the middle of the file. This ensures Arq releases the file handle so that you can unmount your external drive if that's what you're backing up.
  • Fixed an issue where an error in getting the attributes of a file would cause the entire backup to fail.

New in Arq 3.1.1 (May 22, 2013)

New in Arq 3.0.4 (Dec 10, 2012)

  • Fixed Bugs:
  • Glacier vaults which don't belong to any Arq backups are shown under "Other Backup Sets" and can be deleted.
  • Arq will manage the Glacier vault deletion process, including getting the vault inventory (waiting 4 hours for the response), deleting the archives, and deleting the vault. If the vault has been written to within the past day, Amazon will not allow the vault to be deleted and Arq will display an error. Wait 24 hours and try to delete the vault again.
  • Fixed an issue where Arq wasn't deleting unreferenced S3 objects during budget enforcement if there are no S3 folders being backed up.
  • Fixed an issue where attempting to restore from another computer's Glacier backups caused a "failed to open file" error.
  • Fixed an issue where SNS topics and SQS queues were being erroneously deleted from the user's AWS account on startup.
  • Fixed an issue where Arq would give a keychain-item-not-found error when attempting to delete a backup set from "Other Backup Sets".

New in Arq 1.3.15 (May 13, 2010)

  • In “30-day trial” mode, Arq acted as if the trial was expired, whether it was past 30 days or not. Arq 1.3.15 fixes that bug.
