That depends on you. They are pretty much the same process, except copy copies the Catalog info. > I have space to store up to 7 days of backups on the server hard drive.

Keep your File and Job Retention >= your Volume retention. Your disk pool will have Volume = 7 days. Your tape pool, 14 days. > The big benefit that I would see to copying > is that if I need to restore anything within the first 7 days I can simply > restore it from the server > without having to go get a tape and load it.
