Hi.

I used DataKeeper for quite some time now, and repeatedly had problems with it.
First of all, it does _not_ keep a RAID like image, but keeps track of the files that get modified by your applications (and you can also make it do snapshots on request). It does keep a certain (configurable) number of older versions of your files, so I would compare it more to a automized revision control system (without the possibility to mark and comment certain versions) than to a RAID system.
The problems I had with it where numerous though: It was the verified cause of some system hangs, kept keeping copies of files I didn't want it to keep,....
To make a long story short: I wouldn't recommend DataKeeper for backup purposes. It is nice though if you want the ability to step back some file versions when doing excessive editing.
