I've been dealing with Networker for more than 9 years now, but have
never had to deal with clone issues.   With the recent addition of
storage nodes and dedicated storage nodes, we now have the time to run
clones - something we never had the time to do before. 

If I manually clone an Exchange volume via the GUI, it runs in about 2
hours (give or take a few).   If I set the Exchange Group to
automatically clone, once the backups finish, it runs extremely slow -
in fact the past 2 days, after about 8 hours of cloning, it had finished
only 1 tape, and was working on tape 2.   

If I manually clone, I could get all 5 Exchange tapes cloned much
quicker than having it done automatically - do I have something
configure wrong, or is this just the way Networker works? 

FYI - LTO-3 tapes, about 2.5 - 2.6 TB of Exchange data.
