Tak uz jsem nasel chybu...
Pro prvni zalohu jsem hned spoustel  "mt fsf 1", ale tim jsem se na pasce 
hned za zacatku posunul dal, nez bylo potreba..
Ve vysledku tedy :

# /
/usr/bin/mt -f /dev/nsa0 rewind
/sbin/restore if /dev/nsa0

# /var
/usr/bin/mt -f /dev/nsa0 rewind
/usr/bin/mt -f /dev/nsa0 fsf 1
/sbin/restore if /dev/nsa0

# /usr
/usr/bin/mt -f /dev/nsa0 rewind
/usr/bin/mt -f /dev/nsa0 fsf 2
/sbin/restore if /dev/nsa0

Nicmene stale netusim, proc "mt erase" konci chybou... v messages jsem nasel
