Rustic

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

Features:

• Backup data is deduplicated and encrypted.
• Backup storage can be local or cloud storages, including cold storages.
• 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.
• Can use config files for easy configuration of all every-day commands.
• Supports ztsd compression; compression level is customizable.
• Supports to store the repository in a so-called cold storage.
