Restisk

Restisk is a command-line utility designed for backing up and restoring files and directories. It is known for its flexibility and features that make it suitable for both individual users and system administrators. Restisk supports incremental backups, meaning that only the files that have changed since the last backup are saved, which can significantly reduce storage space and backup time. It also offers deduplication, further optimizing storage by identifying and storing identical data blocks only once.

The software allows for encryption of backup data, providing an added layer of security for sensitive information. Users can choose between different encryption methods. Restisk can back up to various backends, including local disk, SSH, and cloud storage services like Amazon S3, Google Cloud Storage, and Backblaze B2. This versatility makes it adaptable to different backup strategies and infrastructure setups.

Restisk provides a command-line interface for initiating backups, performing restores, checking repository integrity, and managing snapshots. Its design emphasizes efficiency and reliability, aiming to provide a robust solution for data protection. The project is open-source and actively developed.
