rustic
Fast encrypted deduplicated backup tool
TLDR
SYNOPSIS
rustic [-r repository] [options] command [args]
DESCRIPTION
rustic is a fast backup tool written in Rust that is fully compatible with the restic repository format. It provides encrypted, deduplicated backups using AES-256 encryption with authenticated tags, ensuring data confidentiality and integrity at rest.The tool uses content-defined chunking and deduplication so that only unique data chunks are stored, significantly reducing storage requirements for incremental backups. Multiple storage backends are supported including local filesystems, S3-compatible object storage, SFTP, and REST servers.Retention policies specified through forget with keep rules (daily, weekly, monthly) automate snapshot cleanup. The prune command reclaims space by removing data chunks no longer referenced by any snapshot.
