If the clones are in the library and the originals out of the library, 
NetWorker should automatically request the clones and work with them, as 
they'll be "closer".

If neither the clones nor the originals are in the library, you can run the 
command:

nsrmm -o offsite X

for any volume 'X'. This will flag it as offsite, which means that if there is 
a saveset instance on that volume, and another instance of the saveset on 
another volume that isn't marked as offsite, NetWorker will request that volume 
instead of the 'offsite' one. Note that 'nsrmm -o offsite' is very different 
from just setting a location flag of 'offsite'.

Once a volume flagged 'offsite' is inventoried in a library, the offsite flag 
is cleared.

Cheers,

Preston.
