Either works, it all depends on what you are trying to achieve.
A Copy pool will help in 2 ways:
1. You have another copy of the data incase of media failure
2. You have a copy of the data incase of Library/DC/Site failure
So if you have you copy pool in the same library as your primary and leave
the tapes in - you are only addressing number 1. If you take them out
every time you run a backup stgpool, you are covering both. Down side is
that it's a manual operation.
Now if your copy pools is in another library AWAY from the primary, you
are covering both AND it's still automated.
It all comes down to cost at the end of the day.
Obviously you need to do the same with DB backups to be able to recovery
anything.

[ADSM-L] storage pool and its copy pool on a tape library
Caterpillar: Confidential Green Retain Until: 18/02/2010
Hi,
What is the best practice to backup a tape storage pool? Is is
possible/recommended to use one tape library (with enough drives) for a
storage pool and its copy pool? How about dedicating a tape library to
copy
storage pool?
thanks so much
