Folder Sync Apps and Alternatives

Data synchronization is the process of setting up consistency among files between two distinct locations, a source and a target one

A folder synchronizing app might be suitable for home backups on either USB flash drives or on external HDDs.

Furthermore, a lot of these apps include copying already identical data prevention or overwriting files with the same name, and, this way, a lot of time can be saved while backing up large quantities of data.

Folder synchronization can also be performed automatically, if and when the contents of a watched folder is modified.
