Recovering Exchange Databases from Exchange Streaming BackupsSets

Recovering Exchange Databases from Exchange Streaming Backups Sets

Individual databases in a storage group may be restored while all other databases remain online. This method is the preferred means of replacing a single failed database. When the database is remounted, pertinent transactions are automatically played back from the storage group's log files to bring the restored database back to the time of the disaster.

When you use Backup to restore Exchange databases, API calls are made to the Exchange Extensible Storage Engine (ESE) to restore Exchange database files and their associated log files. You can use Exchange database backups to restore one or more damaged mailbox stores or public folder stores. You can also use Exchange database backups to restore every mailbox and public folder on the server. In a disaster recovery scenario that involves rebuilding a server, use Backup to restore your Exchange databases after you run Exchange Setup and any Exchange service packs in Recover Server mode (assuming that Active Directory is still available).
