rdiff-backup works like magic. I love it.

It's a command line tool that does all stuff related to backup perfectly. It's in the Debian repos.

It synces a given directory to a backup directory with an additional dir for metadata and history. It's super fast, even over the wire. It seems to achieve this by only sending the changed parts of files. I wonder if it also uses compression?

You can always change your directory back to any state you backed it up.

It has tons of nice features for checking the integrity of the backup, recovering single files from a given point of time etc.

Did I mention how much I love it?
