Doug's script works pretty well. I used a version of it myself for doing this when I was doing the same thing.

Lastly, make sure the >dump blocksize and #blocks/tape numbers match your tape drive (ours is for >a 2GB drive). Just to add something here, another thing to do is to try some of the other encryption methods. The default one is pretty slow, so slow machines don't do well with it (I couldn't get the tape drive to stream at all when using it on the 486dx/66 that the machine used to be). However, some of the other encryptions that ssh offers are faster, and thus would at least let you use *some* form of encryption. I ended up using blowfish because it was fast enough that our slow machine was still able to send data fast enough to stream the drive.
