I can't say much for UNIX backups, but in general I've never had hardware or software compression screw up worse than any other hardware/software combination. I believe in compression because it encourages backups by reducing the media needed, cutting both media cost and time spent swapping volumes. Less media per megabyte up also reduces the chances of an I/O error on media, so compressed backups can be more reliable than uncompressed. Like anything to do with backups, test and then test again. -ahd-
