In Exchange Server 2007, you can only restore databases to the active node of an Exchange CCR cluster. Otherwise, the restore will fail.
If you are restoring to a new location and you want to mount the database, you must first create a database in a recovery storage group through the Exchange Management Shell. For more information, see documentation from Microsoft.
Restoring a single database to a storage group with more than one database could result in data loss from other databases.
If a database’s transaction logs are missing or damaged, an incremental backup after the recovery will not succeed. Perform a full backup before you attempt another incremental backup.
