About:
Tarsnap is a secure, efficient online backup service designed for critical data protection. It provides client-side encryption, ensuring only you can access your backups, and uses deduplication to minimize storage costs. The service is built on a robust infrastructure, offering a 'no trust' model where the server cannot decrypt your data.

Key Features:

Client-side, end-to-end encryption
Block-level deduplication for cost efficiency
Snapshot-based backups with archival capabilities
Low-level access for granular control

Use Cases:

Securing critical server configurations and databases
Creating off-site, encrypted backups for personal or business data
Automating backups for development environments

Alternatives:

restic – Open-source alternative supporting various backends, whereas Tarsnap is a specific paid service.
rsync – Efficient file transfer but lacks built-in encryption and versioning without additional tools.
