Retrospect
Retrospect is a simple and reliable backup program that quietly protects everything on your computers and servers. It automatically makes copies of your important files, photos, and documents so you can get them back if your computer crashes, gets stolen, or a file gets accidentally deleted.
Retrospect uses DiskSpace object storage as its safe vault in the cloud. Instead of filling up your external drives or paying for expensive dedicated backup services, Retrospect sends encrypted copies of your data to DiskSpace S3 storage where it stays protected, organized, and instantly available whenever you need to restore something.
This approach keeps your backups off-site and safe from local disasters while giving you the freedom to choose cheap storage providers that work with S3.
