Thanks for the reply
My customer is not using any form of deduplication.
ok, so it looks like backup stgpool and offsite volumes will have to
continue. I will discuss with the customer.
In terms of the target server, you mention "Your setup on the Target server
"should be" identical to the source server
to ensure you don't 'misplace' data". So on that target server, i run
backup stgpool and migration processing to tape media?
Apologies for all of the questions, but some of what i am looking for is
not covered in the Admin Guide. (Chapter 31)
Regards
