I can't tell you how many times I've requested the ability to multi-select both jobs to prune as well as jobs to be copied for storage policy copies. I suspect that the SQL database can't handle such a huge update if you were to prune too many things at one time, but data aging basically does the same thing depending on how many database updates there are. I guess Commvault is too busy writing patches to address the countless bugs in the software. I'm not bashing, I love the product, but I wish they would implement some of the customer requests.
