Then once again I executed, "mt -f > /dev/sa0" to move the tape to the end (to append to it). You need to use the "norewind" device for the tape. Otherwise the tape will rewind between each operation so each thing, including each backup (even after an eom or mt fsf n), starts at the beginning of the tape. So I use dump -0af /dev/nrsa0 ////jerry > > When I go to execute, "restore -if /dev/sa0" to confirm that both filesystems > were saved so far, there's only ONE filesystem saved to the tape "/".
