Yes, the control files are on one of the BCV volumes; i.e. they're part of
the copy.
Just noticed this in the earlier email. In our BCV backups we excluded
controlfiles to avoid possible corruptions. I am not sure if it's
required though. AFAIK, controlfile transactions are normaly
self-recoverable in case of block split during hot backup using block
version bitmap and alternating two versions of blocks to update.
Checkpoint heartbeat should not be splitted either as it's in one
physical block. Don't know if async IO can cause any problems.
