Hi,
The store.fcl file belongs to the Program Files\Exchsrvr directory.
If the Exchange services are started, then this file will be invariably be active and hence will be skipped during backup.
If you are using the Backup Exec Agent for Exchange then there is no need to backup these files. The selection for the exchange data should be made from the Exchange agent itself.
Please refer to:
During the backup of an Exchange server, the Microsoft Exchange database files are skipped.
