About:
RdiffBackup implements a reverse differential backup strategy, storing the most recent mirror of your data alongside a compact history of changes. It leverages the librsync algorithm to efficiently compute and store only the differences between file versions, minimizing storage space. This approach allows users to quickly recover the latest version of a file or roll back to any previous point in time.
|
Key Features:
- Reverse differential algorithm for efficient storage
- Incremental backups that are fast to restore
- Network-aware operation using SSH
- Preserves permissions, ownership, and timestamps
|
Use Cases:
- Creating efficient, space-saving backups of personal or server data
- Recovering previous versions of files or entire directories
- Automating off-site backups over SSH
|
Alternatives:
-
rsync
– Standard rsync mirrors a directory but does not natively store historical versions without manual scripting.
-
restic
– Restic offers deduplication and supports multiple backends, but uses a repository model rather than direct filesystem access.
