BE 2010 Does Not Use Existing Tape in Media Set

In Backup Exec 2010 I have specific jobs setup to use specific media sets. Job A runs on day 1 and does not find an existing tape for his media set A, so he allocates a new tape and writes the backup data to it. Then Job A runs again on day 2 with the day 1, media set A tape, which is nowhere near full, still in the library and the Overwrite Protection set to Infinite-Don't Allow Overwrite and Appendable Until set to Infinite - Allow Append.

Instead of using the existing tape in media set A, BE allocates another new tape, assigns it to media set A and writes to it. This doesn't happen every time, just often enough to annoy the crap out of me. My library holds 48 tapes and I have 5 media sets assigned to various jobs (some media sets have more than one job assigned to them - i.e. I have both DATA and Active Directory jobs that both use the DATA media set). Of these 5 media sets, 3 of them have two active, non-full tapes in play.

I don't understand why BE would allocate a new tape to the media set when there is already one in use, available and ready for append.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
