I have a 8GB Travan IDE tape drive.  It works fine using /dev/ht0 and
/dev/nht0.  (Actually, recently I've had to use it on /dev/st0 and
/dev/nst0 only because I don't have IDE-SCSI emulation configured
quite correctly for my CD burner.  But back when it was configured
right, those device worked.)

You need IDE device support and IDE tape device support, if you're
compiling your own kernel.  Most stock kernels ship kernels with this
either compiled in or as a module.

Some distros don't create the device files by default; if yours
doesn't, run "/dev/MAKEDEV ide" and you should be set.

After that, the IDE tape drive works just like any other tape drive,
and you can use whatever backup software (tar, cpio, afio, Amanda,
BRU, whatever).

It's in the kernel boot messages and in /proc/ide.
