I need a solution
How can I check what amount of space a full backup will take up? The only thing I can see that sounds like it might do that is Test Run, but this apparently requires a tape to be inserted which it is not presently and I'm remote.
Also if there is a way to do this, does this method take into account whether or not compression is being used, and whether or not you have the Deduplication Option installed?
Thank you.
