I've seen them for Mac (cant remember the name) Amiga (tapeworm) and Dos 
(datman).

A previous employer used the dos version to do their backups.

My GF's work uses one for Mac and they haven't had any problems. 
I've heard that the Mac one works by marking overwritten or deleted files 
as deleted and writes new versions later on the tape. So of course your 
storage get less and less.
