restic
restic is a free, open-source program for backing up files on Linux, macOS, Windows, and BSD. It transfers only changed portions of backed-up files and runs as a single executable without a server or complex setup. Storage options include local repositories, SFTP, REST server, Amazon S3, S3-compatible services, OpenStack Swift, Backblaze B2, Azure Blob Storage, Google Cloud Storage, and rclone. Restic restores snapshots and checks repository metadata or full data integrity. Each repository requires a password, and multiple keys can be managed; losing the password prevents access to stored data. Official binaries are reproducibly built and can be checked with SHA-256 checksums and a PGP signature. The listed backup and restore scope is files. Mobile backup and ransomware protection are listed as unavailable. The latest listed release is restic 0.19.1, released July 5, 2026.
