Incremental Backup For Mac

TimeMachine on Leopard is great. Unless you're running on Tiger. Or unless you have two drives that you want to swap out for rotating backups sets.

The Incremental Backup script will allow you to set up incremental backups from any source, to any destination.

When run, the script does the following: ￭ Creates a folder named with the date in the backup location ￭ Compares the source directory structure to the last-backed-up version ￭ Copies new and modified files from the source to the backup location ￭ Hard-links unmodified files to the backup location ￭ Logs errors and the name of the most current backup folder to text files in the backup location

Since everything is hard-linked, that means you can delete the older folders if you need to reclaim any space. It also means that in the event of a catastrophic failure, recovery is as simple as taking the most recent backup folder and copying it to the destination.

Requirements:

￭ rsync 3.0 or later

NOTE: Be sure to read the Read Me for how to configure the script before running it on your Mac.
