Hi Brian,
Flat files of the Exchange database are restored as any other file by Backup Exec - mounting of the database will not be possible if Exchange is installed and the files are restored from a flat file backup. An online database backup of Exchange, with the Backup Exec Agent for Exchange is actually done by the Exchange ESE.DLL. i.e. the backup is performed by Exchange itself. Tasks such as restoring the database GUIDs and other entries, transaction log related operations etc that are required before a database can be mounted are performed when an online backup of the database is restored. Backup Exec again triggers the Exchange DLL to perform these tasks and is not designed to carry out these actions.
A flat file backup when restored via Backup Exec, will only restore the files but will not be able to mount the database and get it up and running.
Please get in touch with Microsoft to restore the Exchange database from a flat file backup.
We hope the reply answers your question.
