11.3.3 Granular recovery of mailboxes
RDB (RSG) is a special administrative database (storage group) in Exchange Server. It lets you extract
data from the mounted mailbox database. The extracted data can be copied or merged to the
existing mailboxes without disturbing user access to the current data.
For more information about RDB and RSG, refer to the following articles:

Exchange 2010: http://technet.microsoft.com/en-us/library/dd876954

Exchange 2007: http://technet.microsoft.com/en-us/library/bb124039(v=exchg.80)

Exchange 2003: http://technet.microsoft.com/en-us/library/bb123631(v=exchg.65)
To recover a mailbox
1. If a RDB/RSG does not exist, create it as described in the following articles:

Exchange 2010: http://technet.microsoft.com/en-us/library/ee332321

Exchange 2007: http://technet.microsoft.com/en-us/library/aa997694(v=exchg.80)

Exchange 2003: http://technet.microsoft.com/en-us/library/bb124427(v=exchg.65)
2. Recover the database files to the RDB/RSG folder structure. For information about recovering
database files, see "Recovering Exchange Server database files from a disk backup" (p. 292).
3. Mount the recovery database. For information about mounting databases, see "Mounting
Exchange Server databases" (p. 292).
4. Proceed as described in the following articles:

11.4 Recovering Active Directory data
Active Directory recovery differs depending on the type of recovery required.
This section considers the following disaster scenarios:

A domain controller is lost but other domain controllers are still available. See “Recovering a
domain controller (other DCs are available)” (p. 293).

All domain controllers are lost (or there was only one). See “Recovering a domain controller (no
other DCs are available)” (p. 294).

The Active Directory database is corrupted and the Active Directory service does not start. See
“Restoring the Active Directory database” (p. 295).

Certain information is accidentally deleted from Active Directory. See “Restoring accidentally
deleted information” (p. 296).
11.4.1 Recovering a domain controller (other DCs are available)
When one of the several domain controllers (DCs) is lost, the Active Directory service is still available.
Therefore, other domain controllers will contain data that is newer than the data in the backup.
In these cases, a type of recovery known as nonauthoritative restore is usually performed.
Nonauthoritative restore means that the recovery will not affect the current state of Active
Directory.
