(The device name prefixed with "n".) Is this what you're looking for? Assuming you're using the rsa0 tape device: mt -f /dev/rsa0 rewind dump -0u -f /dev/nrsa0 filesystemA dump -0u -f /dev/nrsa0 filesystemB ...and so on... These two dumps will now be arranged in sequence on the one tape. And to restore stuff from filesystemB sometime in the future: mt -f /dev/rsa0 rewind mt -f /dev/nrsa0 fsf 1 restore -if /dev/nrsa0 You'll need to be diligent about logging backups, so you can find things later, but it works just fine. Hope this helps. Dave On Thu, 17 Feb 2000, Stephen D.
