BorgBackup (short: Borg) is a deduplicating backup program. Optionally, it supports compression and authenticated encryption.

The main goal of Borg is to provide an efficient and secure way to back up data. The data deduplication technique used makes Borg suitable for daily backups since only changes are stored. The authenticated encryption technique makes it suitable for backups to targets not fully trusted.

Help to use

Easy to use
Initialize a new backup repository (see borg init --help for encryption options):

$ borg init -e repokey /path/to/repo
Create a backup archive:

$ borg create /path/to/repo::Saturday1 ~/Documents
Now doing another backup, just to show off the great deduplication:

$ borg create -v --stats /path/to/repo::Saturday2 ~/Documents
