Hi Neil,

For a whole backup of your system you should do:

mt -f /dev/rst0 rewind
dump 0usdf 200000 1000 /dev/nrst0 /dev/rwd0a       # /
dump 0usdf 200000 1000 /dev/nrst0 /dev/rwd0e       # /var
dump 0usdf 200000 1000 /dev/nrst0 /dev/rwd0f       # /usr
mt -f /dev/rst0 rewind

Note the 'n' in the tape-device, it means "non-rewindable" !
and use the right disk-devices for your system.

Hope this helps
Werner
