Well, instead of having them run the archive twice, you can just create
multiple copy pools.
Send one offsite, keep the other onsite.

But here is another solution: If your data base logs are going to a disk
pool,
run your backup stgpool from your DISKPOOL to create the copy pool tape.

Backup stgpool diskpool tapecopypool

To make that work, you have to manage when migration runs, so that you know
that you can get the offsite tape created BEFORE the data ever migrates off
disk.

That guarantees you never run into the "can't make an offsite copy due to a
tape problem" issue.  (Been there dealt with that before!)
And a nice side effect is that your copy pool tapes take only a fraction of
the tape mounts to create!

Hello!

I have a user that wants 2 copies of their database logs on 2 different
tapes (the onsite tape storage pool is collocated).  They thought that by
archiving the file twice several days apart that it would be on different
tapes (just in case a tape went bad or it never made an offsite copy due to
a tape problem).  Is there a parameter or a certain file configuration that
would allow the user to have 2 copies of the same logs on different tapes?
As of now the only way I can think to do this is to create another onsite
tape storage pool and have them archive their data to both pools.  Is there
a better way?  Thanks!
