rsnapshot is a script for the purpose of repeatedly creating deduplicated copies (hardlinks) for one or more files. You can chose how many hourly, daily, weekly,… copies you’d like to keep and it removes outdated copies automatically. It wraps rsync and ssh (public key auth) which need to be configured before.

Hardlinks need to be on the same filesystem, don’t they? I don’t see how that would work with a remote backup…?

The hard links aren’t between the source and backup, they’re between Friday’s backup and Saturday’s backup

Ahh, ok. Thanks for clarifying.
