Two tape cartridges in one media set - which one will be chosen?
Let's say I have a media set containing one tape which is used and written daily. Let's say the allocated date is 02-Dec-2013
I now add another new tape cartridge to the same media set and erase it so the allocated date is 11-Dec-2013.
On the next backup, which tape will be used? The new one of the older one?
