My old Colorado (Jumbo?) QIC-40 drive which i'm using to occasionally test the ft driver does its job, although it's a mess compared to the SCSI drives, and i simply don't trust it much more than i trust a /dev/null. :-) > I'm looking into DAT or 8MM for tapes..

Uh, DAT is fairly fragile (and abrasive). The experience with 8mm drives is vastly different, and Exabyte is (unfortunately) a true firmware-patch-of-the-week company. There are many reports of good results with their drives, but at least as many reports of miserable failures. Modern QIC drives meet the DAT speeds. My Tandberg 4222 (2.5 GB plus compression) gets ~ 180 KB/s with 1 GB cartridges, that's about the same as an HP-DAT DDS-1 drive does. The Tandberg goes better with 2.5 GB cartridges, between 300 and 500 KB/s. Still, this is not the 900 KB/s and more you can get with some modern DDS-2 drive, but it's often more than the disks can deliver (if they start seeking during the backup). Sure, if you need more, head for DLT... -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
