BorgBackup (short: Borg) is a deduplicating backup program. Compression and authenticated encryption are also supported as options.

Borg's main goal is to provide an efficient and secure backup solution. Thanks to deduplication, the backup process with Borg is very fast and makes Borg very interesting for daily backups. You may notice that Borg is significantly quicker than some other methods, depending on the amount of data and the number of changes you need to back up. With Borg, all data is already encrypted on the client side, which makes Borg a good choice for hosted systems.
