I use a dump like the following as a cron job Monday-Thursday

/etc/dump 0fubsd /dev/nrst1 50 6000 54000 /dev/rid000a
/etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000e
/etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000f
/etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000g
/etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid000h
/etc/dump 5fubsd /dev/nrst1 50 6000 54000 /dev/rid001e

If I to restore something, usually off /dev/rid000h which is our /home
partition, I use the restore as follows.

restore ibfs 50 /dev/nrst1 5

Hope that helps.
