Backup is incredibly important. Obviously there's no best backup tool, but a comparison of the options would be very interesting.
- Graphical Interface? Command line?
- Incremental backups?
- Automatic backups?
- Install method: In standard repositories? PPA?

Déjà Dup
Déjà Dup is (from Ubuntu 11.10) installed by default. It is a GNOME tool intended for the casual Desktop user that aims to be a "simple backup tool that hides the complexity of doing backups the Right Way".
It is a front end to duplicity that performs incremental backups, where only changes since the prior backup was made are stored. It has options for encrypted and automated backups. It can backup to local folders, Amazon S3, or any server to which Nautilus can connect.
Integration with Nautilus is superb, allowing for the restoration of files deleted from a directory and for the restoration of an old version of an individual file.
Note that as of February 2016 this project appears to be almost completely ignoring bug reports with only minor triage activity and the last bugfix dates back to 2014, though there are new releases with minor changes.
