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
