Restic is a free software designed to provide backups that are easy, fast, verifiable, secure, and efficient. It's important for backups to be easy and fast so that doing them can become part of a user's usual routine. Restic allows users to verify backups, which will help to avoid the horrible situation of backup copies being corrupted. Restic encrypts data with industry-standard AES-256 and authenticates data using Poly1305. With so many storage providers charging per byte, space efficient deduplication of backups is very important. Restic supports backing up to a number of destinations -- external hard drives, local storage servers, Amazon S3, Backblaze B2, and several others. The Restic documentation provides a detailed information on all Restic's capabilities. It also includes a step-by-step example with screenshots demonstrating how to configure backup to an Amazon S3 bucket. Restic binaries are available for Windows, macOS, Linux, FreeBSD, and NetBSD. Source code for Restic can be located on GitHub.
