I just figured all this out for myself. To do the dump that will allow multiple file systems, use something like the following: dump -u0 -a -f /dev/nrst0 /usr The -f /dev/nrst0 tells dump to use the non-rewinding form of SCSI tape 0. As for restoring multiple file systems, you need to use the mt command before each restore. For example, if /usr is the first dump session on your tape, simply type restore -i to enter the interactive restore shell and restore from /usr. Then, exit restore, and type mt fsf. This will advance the tape to the next session. Then type restore -i again to restore the next session. The only problem I had was restoring from the first session on the tape. It was really SLOW (but worked perfectly). I was using a DEC TZ04 (I think) to do the dump/restore. If anyone can shed some light on restore hints to improve speed, I'd love to hear them. Par la vie, the TZ04 is a SCSI-2 device.
