I do Copy to tape. Be aware: your tape drive must be on the same SD as your disk storage. Copy and migrate jobs can involve only one SD. You cannot copy/migrate from one SD to another. > If so, how do you deal with pruning?

I keep all retention periods the same. If anything is pruned, the entire job/file/volume is pruned. I think database storage is cheap compared to the hassles of not having the data in the database. -- Dan Langille - http://langille.org ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
