Explanation:
Box 1:You can use the Shell to create a recovery database, a special kind of mailbox database that's used to mount and extract data from the restored database as part of a recovery operation. After you create a recovery database, you can move a recovered or restored mailbox database into the recovery database, and then use the New-MailboxRestoreRequest cmdlet to extract data from the recovered database. After extraction, the data can then be exported to a folder or merged into an existing mailbox. Using recovery databases, you can recover data from a backup or copy of a database without disrupting user access to current data.
Box 2: The database must be in a clean shutdown state. Because an RDB is an alternate restore location for all databases, all restored databases will be in a dirty shutdown state. You can use Eseutil /Rto put the database in a clean shutdown state.
Box 3: A recovery database (RDB) is a special kind of mailbox database that allows you to mount a restored mailbox database and extract data from the restored database as part of a recovery operation.
After you've created an RDB, you can restore a mailbox database into the RDB by using your backup application (or if you have the database and its log files in the file system, by copying them to the RDB file structure). Then you can use the New-MailboxRestoreRequestcmdlet to extract data from the recovered database. After being extracted, the data can then be exported to a folder or merged into an existing mailbox. RDBs allow you to recover data from a backup or copy of a database without disrupting user access to current data.
