 Description   

The subtype of a BinData object can change when the database is backed up and restored using MMS.

In particular, a source database which contains a BinData object with 'subtype 2' will be converted to a BinData object with 'subtype 0'. While the data is still intact this is a change in format which may not cause some confusion ("why does not restored database not contain the same data as the source database?" - it does at the logical level but not at the physical level)

Subtype 2 is deprecated as per the 'BSON spec' but we do not document that the backup and restore process will automatically convert the subtype.

This is still the case, the bug ticket and original customer ticket are linked.

Seems possible. I can't find a matching bug ticket right now. Should be easy to run a test to confirm/deny.
