Is this true?

If we begin placing all unassigned media into the scratch pool
the backups will pull tapes from the scratch pool an assign them to their
respective volume pools.  And then return them to scratch when they expire.

One other concern is that we have different volume pools defined that are
associated with retention periods.  This way we do not mix retentions on to
any single tape.  If we begin using the scratch pool will this become an
issue.  If we begin to mix the weekly and monthly backups then we will not
get our weekly's back for a full year instead of 8 weeks.

This procedure is correct for NBU versions 4.5 FP3 and higher.  I'd 
like to also add one more item.  This option will only return media 
that CAME FROM the scratch pool.

So if you have a tape that's always been in the NetBackup pool and it 
becomes deassigned, it will NEVER go back to the scratch pool.  So as 
an additional step, you may want manually move all unassigned tapes to 
the scratch pool once it's been setup.
