What is Restic?

Restic is a modern backup program that is designed to be fast, efficient, and secure. It is a command-line tool that allows users to create snapshots of their data, which can then be stored locally or remotely. Restic is particularly useful for backing up large amounts of data, as it uses a deduplication algorithm to minimize storage usage. This means that only new or changed data is stored, rather than duplicating existing data.

Main Features

Restic has several key features that make it an attractive option for backup and disaster recovery. These include:

• Snapshotting: Restic creates snapshots of your data, which can be used to restore your system to a previous point in time.
• Deduplication: Restic uses deduplication to minimize storage usage, reducing the amount of data that needs to be stored.
• Encryption: Restic supports encryption, ensuring that your data is protected from unauthorized access.
• Compression: Restic compresses data to reduce storage usage and improve transfer times.
