has anybody got any suggestions regarding this and linux?
Amanda, Bakula, and probably more.
As mentioned, rsync is also able to make incremental backups.
I would say that, roughly, Clonezilla, dd and other cloning tools are good for disaster recovery, especially if you combine them with an incremental tool.
File-by-file backup tools like rsync, Amanda etc are good for restoring files that you deleted or overwrote by mistake.
And there is a large overlap between the two.
