I tried to use kdar and had nothing but problems with it. I think the
problems you experienced are with the application kdar and not with the
linux system it self. If _reliable_ backups are a must I suggest using a
commercial backup program like Microlite BackupEdge. It employs good
verification to ensure a reliable backup has been preformed. You can
download a 60 day eval for free to test.
