Re: using dump?

 The /dev/st0 device will rewind the tape between each dump, so you'll 
end up overwriting all dumps but the final one. 

Instead, use the no-rewind device, /dev/nst0. Then use mt to rewind 
after all dumps have completed: 

    mt -f /dev/st0 rewoffl 

"rewoffl" means "rewind and then take offline" (eject)
