BorgBackup (Borg) is a deduplicating backup program with optional compression and authenticated encryption. It stores data as content-defined chunks so only changes are saved, making it efficient for daily backups to untrusted targets.
Use cases
- back up my laptop daily without wasting disk space
- encrypt backups to an untrusted remote server
- deduplicate backups across multiple machines
- mount an old backup and browse previous file versions
- run efficient nightly backups of VMs or raw disks
- compress and encrypt archives before offsite storage
When to choose
- you need space-efficient, deduplicated backups with full version history
- you want authenticated encryption so the backup target never sees plaintext
- you prefer a simple one-command CLI with no daemons or agents
- you need to mount archives as filesystems via FUSE to restore individual files
When to avoid
- you need a GUI-driven backup solution
- you want continuous real-time backup rather than scheduled snapshots
- you need block-level disk imaging or bare-metal disaster recovery
- you require Windows-native support as a primary platform
