Recovery Storage Group Override

Why
How backup and restore works on the server when Recovery Storage Group is present
The Exchange Information Store automatically redirects all restore operations to the Recovery Storage Group (if a Recovery Storage Group exists on the server). When a Recovery Storage Group is created on a server, Exchange checks to see if the database that is selected for the restore operation is present in the Recovery Storage Group. If it is present, the database files are restored to the Recovery Storage Group. If it is not present, the restore operation stops. Event messages that are similar to the following may appear in the application event log: Event Type: Error Event Source: MSExchangeIS Event Category: Exchange Backup Restore Event ID: 9635 Computer: EXCHANGE Description: Failed to find a database to restore to from the Microsoft Active Directory. Storage Group specified on the backup media is [GUID]. Database specified on backup media is [Database Name] (EXCHANGE), error is 0xc7fe1f42.
