using dump?

[John Abreau]

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)
