My decade old Loader Express with ten 40 GB tapes finally died a couple of months ago. So, I just switched over to a different style. I don't know how applicable it is to your situation. I have used amanda for years to manage tape drives. In the latest version they support backup to hard disk. They have a disk-chg script that acts like it's changing a tape in a tape changer when really it's just pointing at a different directory on the disk. It ends up writing what otherwise would be on a tape to a file in that directory. But, it looks like a tape to amanda.
Since tapes get expensive and disks are relatively cheap I went out and bought a 300 GB USB disk drive for about $90.00. Right now I have amanda configured to back things up onto 6 "virtual tapes" each of about 40GB, which matches the tape capacities I was using. The virtual tapes exist on the 300 MB USB disk drive. That all seems to be working. So, I am backing up 5 days a week onto a backup cycle of 6 tapes. I could mount and unmount the USB disk before and after the backups to make them a little more inaccessible when not performing a backup, but at the moment I don't. I also have an unused 8 port Power control unit that can be controlled by network or serial port. So, eventually I plan on connecting the USB disk drive to this power control unit and then modifying the disk-chg script to turn on the power to the USB disk and then mount it. Once the backup is done I'll unmount the disk drive and turn the power to the USB disk drive off via the APC control. So, my backup device will only be on-line during the backup itself. I can grow this by adding more external USB devices and modifying the disk-chg script to turn on the correct USB drive and mount it so I can have up to 8 USB devices, assuming I use a 4 port USB adaptor since the hardware only has 2 USB ports. I can add disks depending on how far back I want to save data. Each 300 GB should be able to handle a weeks worth of data at the current capacities. Anyway, to just get the 1 week depth was an ~$90.00 solution for me, the best I could find for a refurbished tape drive for my old tape changer was ~$600.00, and I can store things in the way I have been used to for that last decade, using amanda. Since I have a spare APC controller around I can expand on this at ~ $90.00 per week of backup desired, once I've provided a little software glue. Just a thought.
