[CentOS] Tape backup question.

I would use dump and restore to backup the system, it creates an image 
on the tape of the partitions

I would guess the tape device is /dev/nst0

mt -f /dev/nst0 status
dump -0uf /dev/nst0 /dev/sda1

==to backup partition sda1
etc etc

I have a script that does this, that can even pipe it down an encrypted 
ssh tunnel from one linux box to another if the machine housing the tape 
unit is in a different linux box....
