Windows 7 style backup?

Solution 1:

Yes, far surpassing it in fact ;-)

There is Déjà Dup.

DéjàDup allows you to easily back up anything to a local drive, a network drive (e.g. a NAS), Amazon S3 and elsewhere. It's set up in seconds and extremely reliable. You can install it by just clicking the link above.

Backup intervals can be set, and the system will automatically delete old files, if you want it to, after a given amount of time.

Select any storage target for your back up, even my university's web-server (shhh!) :P
All very easy. :-)

You can read all about it at gnome live.

You can restore specific versions of a file as well, the number of versions kept depends on storage and how long you set déjàdup to keep backups. In my example, there's about a version a day for three month for the file.
