[Dump-users] Simple dump scripts for multiple dump files on a tape?

[Eric J. <eje...@sw...>]

Hi all,
   My use of dump so far has been quite rudimentary; periodic level 0
dumps, and then nightly incrementals.  The latter get successively
appended onto the same tape that sits in the tape drive for a few days
while it fills up.  I'd like to make my dump procedure slightly more
robust, so I'd like to verify each backup.  I wonder if anyone has a
basic script they'd be willing to share to handle this in the case where
the dump file isn't at the beginning of the tape.  I think it must go
something like this:

dump 1uaf /dev/nst0 /
mt -f /dev/nst0 bsfm 1
restore -Cf /dev/nst0

After this restore, what is the tape position?  Can I go ahead and
append another dump file?  Or is more tape repositioning needed?

Any thoughts?  I'm sure someone can point out any folly in the above,
and/or has a better solution.

Thanks in advance for the help,

Eric
