I just finished building the backup routine here, and the main stumbling block I ran into was tape speed and capacity. And this is with new 8mm AIT (25gb native, 50gb theoretical compressed). The drive only writes tapes at about 3MB/s (6MB/s compressed), and takes almost an entire day just to dump 4 days of backups to tape (about 50-60 gig). I haven't had time to research it too much, but I've heard rumours of 300gig AIT's out, and I'm hoping those are faster (trying to get a replacement for this slow AIT I'm stuck with now). Almost all of my experience with autoloaders and DAT in general have been bad, btw.

It has a maximum capacity of 48GB using 120m cartridges. I'm curious - is there anyone using this drive that can vouch for its reliability/robustness? Also, I'm curious if anyone is currently using newer technology such as Exabyte's Arrowhead libraries or Qualstar's TLS systems with success?
