See this has been asked before, but didn't see any good answers.
I have 3 backup physical disks in caddies that I manually change out. But I can't tell how much space is actually used on each one. My backup says how much data has been backed up, but that doesn't account for dedupe or compression... which I have turned on, but again, I can't even see how much this is saving or if it is even working. I want to keep as many backups as I can, but I can't really work out how long to keep backups before starting over again withoug being able to tell how much space is used on the drive. This seems like a rather basic function, not sure why it isn't available or exposed for users.
Regards
Bill
