Multiple tape backups

We received a new tape backup drive. SCSI, 4 tape magazine, etc...

Is there a simple way to have tar/mt/cpio/whatever to switch to the next tape in the magazine when the first is full? This product is reconditioned, and we have no manuals for it... however, knowing how intelligent linux is, I figured there might be a way for it to send a command to switch tapes.

I dunno about simple... You have to have software that can talk to the robotics in the tape library and manipulate the changer. There are some packages out on the net that support various flavors of tape libraries. I believe that I saw some links to changer s/w in the Faq for Amanda (, but right now I can't seem to get the the server it's on.
The software in question is "mtx". The URL is:

Awesome! Thanks a bunch... we found another 'option' (using mt to change the tapes) but this is much more robust.

Good work chap!

A counter question - what changer did you get.... I am running like a headless chicked trying to think of a normal way to get 40GB into a 33GB tape ;-)...

What drive do we have? It's a 4 tape system, DSS-2, so with 4 tapes and compression we only have 36gb of storage, however you can get a 12 tape magazine for the drive, allowing 96gb.

I'm not sure the model number, but we got it at go to online store->tape drives, and it's the 4 tape drive for $349
och... dds-2 is damn slow....
