For starters, you need to use the non-rewinding device: /dev/nst0
You can then do something like:

mt -f /dev/nst0 rewind
tar cf /dev/nst0 /usr
tar cf /dev/nst0 /var
tar cf /dev/nst0 /home
mt -f /dev/nst0 rewind
mt -f /dev/st0 asf 1
tar xf /dev/nst0

and restore the /var archive.

mt -f /dev/nst0 status

will return some useful information.
