Hi,
We have a 90M TLZ06 tape. As far as I know its capasity is ~3GB. I want
to increase this amount by compressing using -C and made a script like

 mt -f /dev/rmt0h rew
 vdump -0uCvf /dev/nrmt0h /
 vdump -0uCvf /dev/nrmt0h /usr
 vdump -0uCvf /dev/nrmt0h /root2
 vdump -0uCvf /dev/nrmt0h /usr/local
 vdump -0uCvf /dev/nrmt0h /usr/users/staff
 vdump -0uCvf /dev/nrmt0h -D /usr/users/comp
 vdump -0uCvf /dev/nrmt0h -D /usr/users/student
 vdump -0uCvf /dev/nrmt0h -D /usr/users/academic
 vdump -0uCvf /dev/nrmt0h -D /usr/users/others
 vdump -0uCvf /dev/nrmt0h -D /usr/users/personel
 mt -f /dev/nrmt0h weof

But, aproximately (but I'm not sure exactly, may be less than that ) after
3GB dump. it requires second tape ! But by comression it should dump
about 6GB , I think. Do you have any idea ?
Sincerely.
murat.
