restic

Restic is a fast, efficient, and secure backup program designed for modern cross-platform use. It supports the three major operating systems (Linux, macOS, Windows) and several smaller ones (FreeBSD, OpenBSD), making it a versatile solution for backing up important data. The tool emphasizes security through cryptography to guarantee confidentiality and integrity of your data, assuming that backup storage locations may not be trusted environments.

One of restic's key strengths is its extensive backend support, allowing users to store backups across a wide variety of destinations including local directories, SFTP servers, cloud services like Amazon S3, Google Cloud Storage, Microsoft Azure, BackBlaze B2, and many others via rclone integration. This flexibility ensures users can choose the storage solution that best fits their needs and budget.

Restic is built around five core design principles: being easy to use with frictionless backup and restore processes, fast enough to encourage daily backups, verifiable to ensure data can actually be restored, secure against untrusted storage environments, and efficient through deduplication and incremental snapshots. The tool is ideal for system administrators, developers, and anyone who needs reliable, automated backup solutions with strong security guarantees.
