Carter,
Did you hear if Networker 7 would clone to multiple devices when cloning a
tape...I had heard that one must backup to file devices (a seperate license
in Networker 7 now ) in order for a clone process to write to multiple devices.
I think its one of the most requested or needed features in Networker. I
know some have scripts that do this now with success. I still just have
multiple groups that clone at the same time.
