fast, encrypted, and deduplicated backups

About

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 be used as a restic replacement in most cases.

It is implemented in Rust, a performant, memory-efficient, and reliable cross-platform systems programming language.

Hence rustic supports all major operating systems (Linux, MacOs, *BSD, Windows).

Should I use rustic or restic?

The restic project is older and more mature than rustic, slow with new developments and conservative with changes. rustic was created by a heavy restic contributor who was at some point annoyed about that slow speed. So, rustic is of course very much inspired by restic but is a complete new implementation aiming to be the better restic with respect to features and development speed.

Whether you should use rustic or restic depends on your use case. The best advise is to test both and see which one better fits to your requirements. We have collected some differences between rustic and restic here.

The good news is: You don't have to decide whether to use restic or rustic unless you need some features which are only present in one project. Both projects implement the identical repository format and you can access every repository with restic as well as with rustic. For example, you can use restic to verify your backups made with rustic and vice versa.

rustic Libraries

The rustic project is split into multiple crates:

• rustic - the main binary
• rustic-core - the core library
• rustic-backend - the library for supporting various backends

Features

• Backup data is deduplicated and encrypted.
• Backup storage can be local or cloud storages, including cold storages.
• Backup source can be local or cloud storage.
• Allows multiple clients to concurrently access a backup repository using lock-free operations.
• Backups by default are append-only on the repository.
• The operations are robustly designed and can be safely aborted and efficiently resumed.
• Snapshot organization is possible by hostname, backup paths, label and tags. Also a rich set of metadata is saved with each snapshot.
• Retention policies and cleaning of old backups can be highly customized.
• Follow-up backups only process changed files, but still create a complete backup snapshot.
• In-place restore only modifies files which are changed.
• Uses config files for easy configuration of all every-day commands, see example config files.

Minimum Rust version policy

This crate's minimum supported rustc version is 1.91.0.

The current policy is that the minimum Rust version required to use this crate can be increased in minor version updates. For example, if crate 1.0 requires Rust 1.20.0, then crate 1.0.z for all values of z will also require Rust 1.20.0 or newer. However, crate 1.y for y > 0 may require a newer minimum version of Rust.

In general, this crate will be conservative with respect to the minimum supported version of Rust.
