Thats ok Brian, Commvault is a very complex tool and we are all learning as we go. The way you are explaining it almost makes me think you will have your environment separated by client OS (or not)...If I`m understanding your question, what you can do is to create different storage policies and with libraries.
Those storage policies will be associated with your clients/subclients. Within the storage policy you can configure different libraries.
Thanks again for your post. YES im finding it very complex... Yes you can say I have it separated by client OS. Basically I just want to make sure our SQL backup data to tape doesnt get written to say our Windows/System backup data Tape.. Not sure if you ever played around with netbackup as in netbackup you could create a volume pool such as SQL and assign that Pool to all of the SQL backup policies...
So your saying I need to create a different Storage policy for each category (like a voulme pool in netbackup) such as SQL; Windows/System etc... and associate that with clients/subclients but how do you assoicate the libaries to the storage ploicies... Man this is confusing... :(
