7.4.3 Restoring Data to Recovery Storage Group
7.4.3.a Recovery Storage Group OverviewThe Recovery Storage Group (RSG) is a resource that was first made available in Exchange 2003. This utility allows for the creation of this special Storage Group that can be mounted outside of an actual Exchange Server’s configuration to serve as a target for the restore of backed up data. With an RSG in place, previously backed up data can be restored to an RSG without disrupting the existing structure of the Exchange Server. This can be ideal when previously backed up individual Storage Group data (for example, Mailbox Stores and their contents) must be reviewed, but the Exchange Server must stay up and running.
RSGs can also be useful when correspondence is accidentally deleted or must be recovered in the case of a legal inquiry. Lost correspondence can be retrieved by performing individual mailbox or mailbox component recovery.
Important:
1. Restoring to a Recovery Storage Group on an alternate Exchange Server is not supported.
2. Restoring a VSS based backup to an RSG is not supported in Exchange 2003.

A complete description of Recovery Storage Groups and their usage can be found in the relevant Microsoft Exchange documentation. For more information, refer to the Exchange 2007 article Understanding Recovery Storage Groups at:

2003
Supported Backup Method – ESE Only
The procedures that follow illustrate the steps required to establish an RSG in Exchange 2003 as well as how to use NetVault: Backup to restore backed up data to it.
Creating a Recovery Storage Group (RSG)
Setting up a recovery Storage Group involves two basic steps:
Creating Recovery Storage Group
Adding Databases to be Restored
Complete instructions for both of these procedures can be found in the relevant Microsoft Exchange documentation. For more information, refer to Setting Up a Recovery Storage Group at:
http://technet.microsoft.com/en-us/library/aa997784.aspx
Important: The Database File Locations section detailed in the article Setting Up a Recovery Storage Group requires that the logical name of the desired database be known so that it can be selected for addition to the RSG. Therefore, BakBone recommends that the desired backup saveset be browsed in the Selections tab of the Restore window to record this information prior to performing this procedure.
Restoring Data to Recovery Storage Group (RSG)
With the RSG successfully created and the appropriate database(s) added to it, you can begin restore procedures of the desired data to the RSG.
Important: To avoid complications in a restore of this type, BakBone recommends that individual Storage Groups be restored on a one-per-job basis, that is, only select an individual Storage Group for inclusion in a single restore job.
Depending on your backup and recovery strategy, refer to one of the applicable procedures outlined in the section, Example Restore Sequences on page 64 for instructions on restoring data items in a Backup Saveset to an RSG.
During an RSG restore operation, the Exchange Server APM will redirect recovered data to the RSG rather than overwriting the original database.
After data has been restored to the RSG it must be extracted for viewing. For Exchange 2003, the Mailbox Merge Wizard (ExMerge) tool is the only supported method of extracting data from a database in an RSG. See the relevant Microsoft Exchange documentation pertaining to the use of this utility. For more information, refer to Salvaging Data from the Recovery Storage Group in Exchange Server 2003 at:

Viewing Data Restored to Recovery Storage Group (RSG)
For Exchange Server 2007, the Exchange Troubleshooting Assistant (ExTRA) and Windows PowerShell included with Exchange 2007 may be used to extract data from a database in an RSG. Refer to the relevant Exchange documentation for details on the use of these utilities. For additional information, refer to Exchange 2007 How to Recover a Mailbox by Using a Recovery Storage Group at:

7.4.4 Disaster Recovery of Exchange Server
This section offers a brief synopsis on how to fully recover an Exchange system utilizing backups performed with the Exchange Server APM. This procedure can be used to rebuild an Exchange Server completely if the original was destroyed or is otherwise unusable. If you are completely rebuilding an Exchange Server, the Active Directory service should be available in Disaster Recovery Mode.
The restore sequence performed should bring the Exchange Server up to the most current point before the failure of the Exchange Server. This could include restoring a Full Backup, a Full Backup + a Differential Backup, or a Full +
Incremental Backup(s) depending on your Exchange Server backup and recovery strategy. However, BakBone strongly recommends that the Microsoft
documentation for the Exchange version in use be consulted for complete details on the proper way to perform this type of recovery. For additional information:
