Report on Media moves between Media Sets

We are currently running BE2012 in conjunction with a FalconStor VTL.

Within BE we have created 3 media sets (Daily, Monthly and Annual) with their respective retention periods.

The issue we face is that a tape stored within our annual media set will receive a retention period of 10 years, however if I drag this media into scratch (or any other media set) the retention period changes to reflect the retention period of the new media set the tape resides in.

From an Audit point this is a risk because if a tape is moved by mistake we have no way of knowing until it’s to late.  Is there a report  that we run on a daily basis that shows if tapes are moved between media sets?

Thanks
