What is rdiff-backup and how does it work?
Rdiff-backups are backups based on the rdiff-backup tool. This free tool makes copy backups, but does so in a unique way.
The software initially works by creating a mirror copy of the data to a target storage device. Once the initial copy has been made, only the differences are backed up from that point forward. These differences (diffs) are stored in a dedicated subdirectory. This allows for point-in-time recovery capabilities. The backup works as a mirror copy and an incremental backup in one.
