Borgmatic is a free and open source configuration-driven wrapper around Borg, the secure and space-efficient archiver. Borgmatic allows us to orchestrate Borg backups by setting redundancy, rotations, hooks and many other things in a central place: an human-friendly and very well commented configuration file.
Borg is a very useful application we can use to create deduplicating backups on Linux. Free and open source software, it is, for the most part, written in Python and supports data compression and encryption. Thanks to the data de-duplication feature, only data which actually changes is archived, and this let us optimize both disk space and execution time. Borg is really easy to install, since it is packaged and included in the repositories of the most used Linux distributions.
