Ray - Yes, the copy stgpool knows that it already has a copy.
Keep in mind that server storage files are not identified by where they are at
the moment, but rather by originating nodename, filespace, and file name
(primarily). Thus, whether the file is in the disk pool because of not yet
having been migrated or caching, and then later in the tape pool, Backup
Stgpool can tell whether there already is a copy in the Copy Storage Pool and
thus not have to make a copy.
