Commonly known as RDB, Recovery Database is an out-of-the-ordinary mailbox database that permits you to mount and then extract data from a restored mailbox database as part of a recovery process. RDBs allow restoring data from the backup or copy of the database without restricting or disturbing users in accessing the data of the mailboxes saved in the Exchange Server database.
After you create an RDB, you can restore the mailbox database into the RDB by using a backup or by copying a database and its log files into the RDB folder structure. Thereafter, you can use the New-MailboxRestoreRequest cmdlet to extract data from the restored database. Once you extract the mailbox data, you can export it to a folder or merge into an existing mailbox.
