Does anyone have any suggestions for a moderately-priced USB backup
solution?  I'd like something with removable cartridges (I have three
machines to back up, and would like each one on a separate cartridge) and
which can hold around 20GB per cartridge.

The Seagate Travan 20GB USB tape drive is the perfect solution, except that
it doesn't seem to be Linux-compatible.  (It seems that it has a Freecom USB
controller which is causing problems:
http://www.qbik.ch/usb/devices/showdv.php3?id=445)  More on the trials with
that drive can be found at the end of the message, in case anyone can offer
a fix.

Thanks for any recommendations.


As for the Seagate drive, I'm running RH 7.2 (kernel 2.4.7).  There is an
option in the kernel configuration for Freecom USB/ATAPI bridge support, but
it doesn't seem to help.  With both the out-of-the-box kernel and a
recompiled version (making sure that option is set), I can get the drive
detected with a manual 'insmod usb-storage' - it takes about 5 minutes to
complete, but once it is done, /proc/scsi/scsi shows:
Host: scsi1 Channel: 00 Id: 00 Lun: 00
  Vendor: Seagate  Model: STT20000A        Rev: 8A51
  Type:   Sequential-Access                ANSI SCSI revision: 02
(Interestingly, the model number on this particular drive is STT6201U-R;
from the model numbers, it seems like it is being recognized as a generic
internal TR-5 ATAPI drive - STT20000A doesn't seem to exist as a model
number, but STT22000A is the 20GB internal TR-5 ATAPI drive.)

Trying to access the drive (e.g. 'mt -f /dev/st0 status') results in error
messages:
Oct 31 11:37:56 lumini kernel: st0: Error with sense data: Current st09:00:
sense key Illegal Request
Oct 31 11:37:56 lumini kernel: Additional sense indicates Invalid command
operation code
It looks to me like the driver isn't talking to the drive in a way it
understands.

If anybody knows of a way to fix this, I'd be grateful.
