BorgBackup is a deduplicating backup program that supports compression and authenticated encryption.
BorgBackup solves the problem of efficient and secure data backup by using deduplication to store only changes between backups, making it suitable for daily backup schedules. The tool applies authenticated encryption to protect backups stored on untrusted targets. It combines these techniques to minimize storage requirements while maintaining security guarantees for backed-up data.
BorgBackup suits users who need reliable incremental backups with strong encryption and want to minimize storage overhead through deduplication. It works well for both local and remote backup scenarios. The README explicitly warns that Borg2, the current development version, is in beta testing and may undergo breaking changes between releases, with no upgrade path between beta versions. The README strongly advises against using Borg2 for production backups and recommends setting it up only as a supplement to existing production backup systems while helping with testing.
The project maintains active communication channels including web chat and a mailing list for user support and discussion. Development activity includes a public issue tracker where users can report problems and request features. The project accepts monetary contributions and has established a security contact for reporting vulnerabilities responsibly.
