rustic - fast, encrypted, deduplicated backups powered by pure Rust

Rustic is a backup tool that provides fast, encrypted, deduplicated backups. It reads and writes the restic repo format described in the design document and can therefore be used as a complete replacement for restic.

Note that rustic currently is in an beta release and misses tests. It is not yet considered to be ready for use in a production environment.

Are binaries available?

Sure. Check out the releases. Binaries for the latest development version are available here.

Comparison with restic:

Improvements:

• Allows using cold storage (e.g. AWS Glacier) repos which are only read in the restore command + supports warm-up
• All operations are completely lock-free as rustic supoorts two-phase-pruning (prune option instant-delete is available)
• Supports configuration in a config file (example config files)
• Huge decrease in memory requirement
• Already faster than restic for most operations (but not yet fully speed optimized)
• Cleaner concept of logging output; possibility to write logs to a log file
• rustic repair command allows to repair some kinds of broken repositories
• backup command can use .gitignore files
• restore uses existing files; also option --delete available
• Snapshots save much more information, available in snapshots command
• Integrates the Rhai script language for snapshot filtering
• Allows to save repository options in the repository config file via the command config
• New command merge
• New command repo-info
• check command checks and uses cache; option --trust-cache is available
• Option prune --fast-repack for faster repacking
• Syntax <SNAPSHOT>[:PATH] is available for many commands

Current limitations:

• Supported platforms are Linux and MacOS and other Unixes, Windows support is experimental

Open points:

• Add tests and benchmarks
• Add missing commands: find, mount
• Improve error handling
• Parallelize the code even more and optimize for speed where useful
