Administrator Guide

The LUN mapping range is configurable through the Exchange Verification Setup screen. If you have LUN numbering
requirements or want to reserve certain ranges for verification, it is possible to configure it accordingly. Replay Manager
allows LUN numbers 1 through 254. See for information on installing and configuring the Verification Service.
● Use of Expose and Restore to Recover Exchange:
Replay Manager offers two methods for recovering data: Restore or Expose. Both methods provide immediate access to the
data using the snapshots.
The Restore function provides the easiest method for recovering a Storage Group. By selecting the restore point and then
clicking Restore Backup Set, the Restore operation accesses the requested restore point and copies the transaction logs
and databases contained within the backup set back to the production volumes. Using Restore requires a dismount of the
existing Storage Group and databases since the Restore replaces all Storage Group components. Depending on the size of
the database, this can be a time consuming operation as data is copied from one volume to another. This one-click approach
is easy for administrators to use; however Restore provides only a point-in-time recovery from which the restore point was
created.
The Expose function provides more flexibility for recovering individual components. When a restore point is exposed as a
drive letter or mount point, an administrator can then manually select components to recover.
NOTE: Restoring a Replay will eliminate any changes made since the Replay was taken. It is advised to create a Replay after
all changes are made to a database or use the Expose function to manually merge the Replay data with the existing data
set.

Recover a Mailbox
To recover an individual mailbox, Expose the restore point as a drive letter or mount point. Once the snapshot is exposed, an
administrator can recover a mailbox using a Recovery Storage Group or Recovery Database and the built-in tools of Microsoft
Exchange Server.
1. Locate and Expose the restore point that contains the mailbox as described in Expose a Restore Point (Windows Extensions
Only) on page 40.
2. In the Expose Restore Point Volumes dialog box:
a. Make sure that you expose both the Database and the Log volumes, by setting drive letters for both volumes shown.
b. Select Make exposed volumes writable.
3. Click Expose.
4. To verify that the drive was created, use the Computer Management console on the server:
a. Right-click the computer where the drive should appear and select Manage.
b. In the Computer Management navigation tree, expand the Storage entry.
c. Select Disk Management.
d. If the drive does not appear, select Action→ Rescan Disks.
5. Use the Exchange Management Shell to recover the mailbox database:
a. Create a database pointer for the recovery files.
b. Specify the path to the exposed files.
For example:
C:\>new-mailboxdatabase -recovery -name Emailrecovery1 -server ex2010-mb1 -EdbFilePath
“h:\replay users\replay users.edb" -logfolderpath "h:\replay users"
Where Emailrecovery1 is the database name, ex2010-mb1 is the server name, and h:\replay users is the path of the
exposed files.
6. Use the ESEUTIL program to put the database into a clean shutdown.
NOTE:
In the preceding example, all files residing in ”h:\replay users “ are immediately available for recovery. If
files outside that directory are required, copy them into the path of the exposed files (in this case h:\replay users).
7. In the Exchange Management Organization Configuration/Mailbox dialog box, right-click the recovered database and
select Mount Database.
