How to use Recovery Storage Groups in Exchange Server 2003




                                This article describes the new Recovery Store Group feature in Exchange Server 2003. By using
                                the Recovery Storage Group feature, you can mount a second copy of an Exchange mailbox
                                store (database) on the same computer as the original mailbox store, or on any other Exchange
                                computer that is in the same administrative group. You can use the Recovery Storage Group
                                feature to recover mailbox data without having to install and to configure a separate Exchange
                                recovery computer.


                                This article contains information about how the Recovery Storage Group feature works. This
                                article discusses how to create a Recovery Storage Group, how to restore mailbox data to a
                                Recovery Storage Group, and how to extract recovered mailbox data from the Recovery Storage
                                Group.


                                Overview of How Recovery Storage Groups Work
                                In versions of Exchange Server that are earlier than Exchange Server 2003, you must configure
                                a separate Microsoft Active Directory directory service forest on a recovery server if you want to
                                mount another copy of a production Exchange database or to mount a different version of a
                                production Exchange database. With the Recovery Storage Group feature in Exchange Server
                                2003, a separate recovery computer is not required in certain situations when you want to
                                recover data from a mailbox store. After you create a Recovery Storage Group, and after you
                                add one or more databases to it, you can either restore online backup sets or you can copy
                                offline database files to the Recovery Storage Group. To extract or to merge data from recovered
                                databases in the Recovery Storage Group to a mailbox in a regular storage group, use the
                                Exchange Server 2003 version of Microsoft Exchange Mailbox Merge Wizard (Exmerge.exe).


                                To use a Recovery Storage Group, the Active Directory topology of the Exchange Server 2003
                                computer must be intact and must be in the same state as when the copy of the database was
                                made. This means that the mailbox or the mailboxes that you want to recover must not be
                                deleted or purged from the system, or moved to a different database or to a different server.


                                The Recovery Storage Group feature is not intended for use in disaster recovery operations that
                                involve multiple servers or multiple storage groups. It is intended as a substitute in situations
                                where previously, an alternative forest recovery server was required. Use the Recovery Storage
                                Group feature in recovery situations where both the following conditions are true:


                                         The logical information in Active Directory about the storage group and its mailboxes is
                                         intact and unchanged.
                                         You want to recover data from a single mailbox, a single database, or a group of
                                         databases that are in a single storage group. For example, you can use a Recovery
                                         Storage Group to recover items that were deleted and purged from a user's mailbox, or
                                         you can use a Recovery Storage Group to restore or to repair a copy of an alternative
                                         database while another copy of the database remains in production.


                                How a Recovery Storage Group Is Different from a Regular Storage Group
                                A Recovery Storage Group is a specialized storage group that can exist with regular storage
                                groups. Although a Recovery Storage Group is similar to a regular storage group, Recovery
                                Storage Groups differ from regular storage groups in the following ways:


                                         All protocols except MAPI are disabled. This means that you cannot send mail to or
                                         receive mail from a mailbox store that is in a Recovery Storage Group. However, you can
                                         use the Exmerge.exe tool to access mailboxes to recover data.
                                         You cannot connect user mailboxes in a Recovery Storage Group to user accounts in
                                         Active Directory. The only supported method that you can use to access mailboxes in a
                                         Recovery Storage Group is by using the Exchange Server 2003 version of the
                                         Exmerge.exe tool.
                                         You cannot apply system and mailbox management policies to a Recovery Storage Group.
                                         Online maintenance and defragmentation do not run against databases in the Recovery
                                         Storage Group.
                                         You must manually mount databases in the Recovery Storage Group. You cannot

How to use Recovery Storage Groups in Exchange Server 2003                                                 Page 2 of 8



                                configure the databases to automatically mount in Exchange System Manager.
                                You cannot change path locations or move data files after a Recovery Storage Group is
                                created because those actions are not supported. If you want to change the location of
                                the files in a Recovery Storage Group, you have to delete and then re-create the
                                Recovery Storage Group.
                                You can only recover mailbox stores to a Recovery Storage Group. You cannot restore a
                                public folder store to a Recovery Storage Group because that action is not supported. The
                                methods that you use to recover a public folder store in Exchange Server 2003 are the
                                same methods that you use in Exchange 2000 Server.
                                You can restore any private mailbox store from any computer that is running Exchange
                                Server 2003 or Exchange 2000 Service Pack 3 (SP3) or later to a Recovery Storage
                                Group, if the computer that contains the private mailbox store and the computer that
                                contains the Recovery Storage Group are both located in the same administrative group.


                                Note When you restore a mailbox store to the Recovery Storage Group, the mailbox store
                                is upgraded to the version of the mailbox store that currently is running on the computer.
                                This means that you must upgrade the original computer to the version of Exchange that
                                is running on the computer where the Recovery Storage Group is located before you can
                                copy the databases back to the original computer. For example, if you restore a mailbox
                                store from a computer that is running Exchange 2000 Server SP3 to a Recovery Storage
                                Group that is stored on a computer that is running Exchange Server 2003, you must
                                upgrade the original computer to Exchange Server 2003.


                                You can use the Exmerge.exe tool to move or to copy mailbox data between servers
                                regardless of the version of Exchange Server that is running on the computers.
                                By default, data is restored to the existing Recovery Storage Group on the computer.
                                If you restore multiple databases to a Recovery Storage Group, all databases that you
                                add to the Recovery Storage Group must be from the same storage group.
                                You can only have one Recovery Storage Group on a computer.
                                You can only have one Recovery Storage Group per two-node cluster, regardless of the
                                number of Exchange virtual servers that are present. For clusters that contain more than
                                two nodes, each Exchange virtual server can have its own Recovery Storage Group.
                                Recovery Storage groups cannot be used to restore Exchange backups that were
                                performed using third-party software that supports the Volume Shadow Service in
                                Microsoft Windows Server 2003. Recovery Storage Groups can be used only to restore
                                backups performed by an Exchange-aware backup application. Backup snapshots that
                                were taken by using Volume Shadow Service can be restored only by using Volume
                                Shadow Service.


                         How the Recovery Storage Group Links Back to the Original Database
                         A Recovery Storage Group uses the following two Active Directory attributes to link a copy of the
                         database with its original database:


                                The msExchMailboxGUID attribute:


                                The first test that a mailbox must pass before you can recover data from the mailbox by
                                using a Recovery Storage Group is that the mailbox GUID must correspond to a user in
                                Active Directory.


                                The mailbox GUID is a unique value that distinguishes a mailbox from all others. The
                                mailbox GUID is created in the mailbox store when the mailbox is created, and the value
                                remains the same for the lifetime of the mailbox. The msExchMailboxGUID attribute
                                uses the mailbox GUID value from the mailbox store. The msExchMailboxGUID
                                attribute is set on the user who owns the mailbox when you link a mailbox to a user
                                account in Active Directory. The Exmerge.exe tool uses the msExchMailboxGUID
                                attribute to match the mailbox in the Recovery Storage Group with the original mailbox.


                                When you delete a mailbox, mailbox attributes are removed from the user object in
                                Active Directory that previously owned the mailbox. As a result, you cannot use a
                                Recovery Storage Group to recover a deleted mailbox.
                                The msExchOrigMDB attribute:


                                The second test that a mailbox must pass before you can recover data from the mailbox
                                by using a Recovery Storage Group is that the mailbox must exist in the original mailbox
                                store where the Recovery Storage Group was created. The msExchOrigMDB attribute is

How to use Recovery Storage Groups in Exchange Server 2003                                                       Page 3 of 8



                                set on each database object in the Recovery Storage Group and it specifies the
                                distinguished name of the original database where the Recovery Storage Group was
                                created. If you move the mailbox to a different mailbox store, you cannot use the
                                Exmerge.exe tool to extract data from the mailbox. To resolve this issue, do one of the
                                following:
                                       Move the mailbox back to the original mailbox store.
                                       Modify the msExchOrigMDB attribute on the Recovery Storage Group database to
                                       point to the mailbox store that you moved the mailbox to.


                                       When you use this option, you cannot use the Exmerge.exe tool to access any
                                       mailboxes that you did not move to a different mailbox store. If you want to
                                       access the mailboxes that remain in the original mailbox store, you must change
                                       the msExchOrigMDB attribute back to its original value.


                                       To modify the msExchOrigMDB attribute by using ADSI Edit, follow these
                                       steps.Warning If you use the ADSI Edit snap-in, the LDP utility, or any other
                                       LDAP version 3 client, and you incorrectly modify the attributes of Active Directory
                                       objects, you can cause serious problems. These problems may require you to
                                       reinstall Microsoft Windows 2000 Server, Microsoft Windows Server 2003,
                                       Microsoft Exchange 2000 Server, Microsoft Exchange Server 2003, or both
                                       Windows and Exchange. Microsoft cannot guarantee that problems that occur if
                                       you incorrectly modify Active Directory object attributes can be solved. Modify
                                       these attributes at your own risk.
                                             1.   Start ADSI Edit.
                                             2.   Locate the mailbox store that you moved the mailbox to. To do so, expand

                                                  expand CN=Services, expand CN=Microsoft Exchange, expand
                                                  CN=YourOrganizationName, expand CN=Administrative Groups,
                                                  expand CN=Your Administrative Group, where Your Administrative
                                                  Group is the administrative group that contains the storage group that you
                                                  want to modify), expand CN=Servers, expand CN=YourServerName,
                                                  expand CN=InformationStore, and then click CN=YourStorageGroup.
                                             3.   In the right pane, right-click the database object, and then click

                         Recovery SG Override Registry Key
                         The Exchange Information Store automatically redirects all restore operations to the Recovery
                         Storage Group (if a Recovery Storage Group exists on the server). When a Recovery Storage
                         Group is created on a server, Exchange checks to see if the database that is selected for the
                         restore operation is present in the Recovery Storage Group. If it is present, the database files
                         are restored to the Recovery Storage Group. If it is not present, the restore operation stops.
                         Event messages that are similar to the following may appear in the application event log:

                         If you delete the Recovery Storage Group, the information store reverts to typical restore
                         behavior. That is, restore operations are not automatically redirected to the Recovery Storage
                         Group.


                         If you do not want to restore data to the Recovery Storage Group and you do not want to delete
                         the Recovery Storage Group, create the Recovery SG Override value in the following registry
                         key, and then set the value to 1:
                            HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \MSExchangeIS
                            \ParametersSystem

                         When you create this value, the information store ignores the Recovery Storage Group during a
                         restore operation. Important This section, method, or task contains steps that tell you how to
                         modify the registry. However, serious problems might occur if you modify the registry
                         incorrectly. Therefore, make sure that you follow these steps carefully. For added protection,
                         back up the registry before you modify it. Then, you can restore the registry if a problem occurs.
                         For more information about how to back up and restore the registry, click the following article
                         number to view the article in the Microsoft Knowledge Base:

                            Windows


                         To create and configure the Recovery SG Override registry value:


                            1.    Click Start, and then click Run.
                            2.    In the Open box, type regedit, and then click OK.
                            3.    Locate and then click the following registry key:
                                     HKEY_LOCAL_MACHINE \System \CurrentControlSet \Services \MSExchangeIS
                                     \ParametersSystem

                            4.    On the Edit menu, point to New, and then click DWORD Value.
                            5.    Type Recovery SG Override, and then press ENTER.
                            6.    On the Edit menu, click Modify
                            7.    In the Value data box, type 1, and then click OK.
                            8.    Quit Registry Editor.


                         Important Make sure that you delete the Recovery SG Override registry value when you no
                         longer require it.


                         Create a Recovery Storage Group
                         To create a Recovery Storage Group:


                            1.    Start Exchange System Manager.
                            2.    Expand Administrative Groups (if appropriate), expand AdministrativeGroupName
                                  (if appropriate), and then expand Servers.
                            3.    Right-click ServerName, point to New, and then click Recovery Storage Group.
                            4.    In the Name box, type a name for the Recovery Storage Group.


                                  Try to use the same name that you used for the original storage group when you specify
                                  a name for the Recovery Storage Group. If you receive an error message that is similar to
                                  the following when you do so, use a different name for the Recovery Storage Group:

                                 The object StorageGroupName already exists. Enter a unique directory name for this
                                 object.



                           5.   In the Transaction log location and in the System path location boxes, specify a
                                location for the transaction log files and for the system path. Make sure that the location
                                that you specify for the transaction log files for the Recovery Storage Group is different
                                from the location that is specified for the transaction log for the original storage group.
                           6.   Click OK.
                           7.   Right-click the Recovery Storage Group that you created, and then click Add Database
                                to Server
                           8.   In the Select database to recover dialog box, click the mailbox store that you want to
                                add to the Recovery Storage Group, and then click OK.
                           9.   In the Mailbox Store Properties dialog box, review the properties of the mailbox store,
                                and then click OK.


                         Restore a Mailbox Store to the Recovery Storage Group
                         You can restore a mailbox store to a Recovery Storage Group by using either of the following
                         methods:


                                Restore a mailbox store from an online backup.
                                Manually copy database files to the appropriate folder on the server.


                         Restore a Mailbox Store from an Online Backup


                           1.   If databases are currently mounted in the Recovery Storage Group, do the following:
                                    a.   Dismount the databases.
                                    b.   Use the Eseutil.exe command-line tool to verify that the databases are in a "clean
                                         shutdown" state. To do so, open a command prompt, switch to the ExchSrvr\Bin
                                         folder, type the following line, and then press ENTER:
                                            Eseutil /mh YourDatabaseName.edb

                                         In the output that appears in the Command Prompt window, note whether the
                                         State line shows as State: Clean Shutdown or State: Dirty Shutdown. If the
                                         databases are consistent, delete all transaction log files (.log) and checkpoint files
                                         (.chk) for the Recovery Storage Group.
                           2.   Restore a full backup set to the server where the Recovery Storage Group is located.


                                If you are not restoring additional differential or incremental backups, or if you are not
                                adding additional log files, configure a hard recovery to run automatically. If you use
                                Microsoft Backup, you configure a hard recovery to run automatically when you click to
                                select the Last Backup Set check box.
                           3.   Verify that the database that you want to restore is consistent and that it is in a "clean
                                shutdown" state. To do so, open a command prompt, switch to the ExchSrvr\Bin folder,
                                type the following line, and then press ENTER:
                                    Eseutil /mh YourDatabaseName.edb

                                In the output that appears in the Command Prompt window, note whether the State line
                                shows as State: Clean Shutdown or State: Dirty Shutdown.
                           4.   Do one of the following, as appropriate to your situation:
                                         If the database is consistent, go to step 5.
                                         If the database is not consistent, manually perform a hard recovery. To do so,
                                         open a command prompt, switch to the ExchSrvr\Bin folder, type the following
                                         line, where Path of the Restore.env file is the path of the folder that contains the
                                         Restore.env file on the hard disk, and then press ENTER:
                                            Eseutil /cc Path of the Restore.env file

                                         When the hard recovery operation completes successfully, the Restore.env file is
                                         deleted.
                           5.   Start Exchange System Manager, and then view the properties of the database that you
                                restored. On the Database tab of the Mailbox Store Properties dialog box, verify that
                                the This database can be overwritten by a restore check box is selected.
                           6.   Mount the database.

                            1.   Verify that the database that you want to restore is consistent and that it is in a "clean
                                 shutdown" state. To do so, open a command prompt, switch to the ExchSrvr\Bin folder,
                                 type the following line, and then press ENTER:
                                    Eseutil /mh YourDatabaseName.edb

                                 In the output that appears in the Command Prompt window, note whether the State line
                                 shows as State: Clean Shutdown or State: Dirty Shutdown.
                            2.   Do one of the following, as appropriate to your situation:
                                         If the database is consistent, go to step 3.
                                         If the database is not consistent and if the database log files exist, use the
                                         Eseutil.exe tool to perform a soft recovery on the database. When you perform a
                                         soft recovery, uncommitted logs are committed to the database. To perform a soft
                                         recovery, switch to the ExchSrvr\Bin folder at a command prompt, type the
                                         following line, where rnn is the log file prefix and database_folder_path is the
                                         name of the folder where the database file is located, and then press ENTER:
                                            eseutil /r rnn /i /ddatabase_folder_path

                                         For example, you might type the following:
                                            eseutil /r r00 /i /d"c:\Program Files\Exchsrvr\Recovery Storage
                                            Group"

                                         Note There is no space after the /d switch.
                                         If the database is not consistent and if the database log files do not exist, use the
                                         Eseutil.exe tool to perform a hard repair on the database.


                                         Warning When you use the following command, Exchange Server data loss
                                         occurs. Data loss can be significant; however, in most situations the data loss is
                                         minimal. The following command is a hard or forcible state recovery command.
                                         Use it only if the database does not return to a consistent state after you run the
                                         Eseutil /mh YourDatabaseName.edb command.


                                         To perform a hard repair, open a command prompt, switch to the ExchSrvr\Bin
                                         folder, type the following line, and then press ENTER:
                                            eseutil /p YourDatabaseName.edb

                            3.   Immediately after the successful completion of the hard repair, perform an offline
                                 defragmentation of the repaired database. To perform an offline defragmentation, open a
                                 command prompt, switch to the ExchSrvr\Bin folder, type the following line, and then
                                 press ENTER:
                                    eseutil /d YourDatabaseName.edb

                            4.   Copy the .edb and the .stm database files to the appropriate folders that you specified
                                 earlier when you created the Recovery Storage Group.
                            5.   If databases are currently mounted in the Recovery Storage Group, do the following:
                                    a.   Dismount the databases.
                                    b.   Use the Eseutil.exe tool to verify that the databases are in a "clean shutdown"
                                         state. To do so, open a command prompt, switch to the ExchSrvr\Bin folder, type
                                         the following line, and then press ENTER:
                                            Eseutil /mh YourDatabaseName.edb

                                         In the output that appears in the Command Prompt window, note whether the
                                         State line shows as State: Clean Shutdown or State: Dirty Shutdown. If the
                                         databases are consistent, delete all transaction log files (.log) and checkpoint files
                                         (.chk) for the Recovery Storage Group.
                            6.   Start Exchange System Manager, and then view the properties of the database that you
                                 restored. On the Database tab of the Mailbox Store Properties dialog box, verify that
                                 the This database can be overwritten by a restore check box is selected.
                            7.   Mount the database.


                         Extract or Merge Mailbox Data from the Recovery Storage Group to the
                         Regular Storage Group
                         Use the Exchange Server 2003 version of Microsoft Exchange Merge Wizard (Exmerge.exe) to
                         extract data from a database in a Recovery Storage Group to the mailbox of the user in the
                         regular storage group. For more information about how to obtain the Exmerge.exe tool, visit the

How to use Recovery Storage Groups in Exchange Server 2003                                                     Page 7 of 8



                         The same Exmerge.exe functionality that is available for databases that are in regular storage
                         groups is available for databases that are in a Recovery Storage Group. However, note the
                         following differences that apply when you use the Exmerge.exe tool with a Recovery Storage
                         Group:


                                  You do not have to override the Deny setting that is configured for the Receive As
                                  permission for members of the administrative group when you extract data from the
                                  Recovery Storage Group. However, when you merge data back to the regular storage
                                  group, you have to add the appropriate user account to the mailbox store, and you have
                                  to assign the account the Receive As permission.
                                  The original mailbox must still be present in the original database and must still be
                                  connected to an Active Directory user account. The following considerations apply:
                                         If the mailbox is disconnected, the Exmerge.exe tool does not display the mailbox
                                         in the list of available mailboxes.
                                         If the mailbox is moved to a different database, the mailbox appears in the list of
                                         available mailboxes, but the Exmerge.exe tool cannot extract data from it.
                                         If the mailbox is disconnected from a user in Active Directory and then is
                                         reconnected to a different user in Active Directory, and the mailbox remains in its
                                         original database, the Exmerge.exe tool can extract the mailbox data from the
                                         Recovery Storage Group. However, the Exmerge.exe tool uses the mailNickname
                                         attribute of the current mailbox owner as the display name of the mailbox, and it
                                         uses the attribute of the previous owner of the mailbox as the directory name. The
                                         resulting .pst file uses a name that is based on the mailNickname attribute of the
                                         previous owner. You must rename the .pst file to match the mailNickname
                                         attribute of the current owner of the mailbox before you can import the mailbox
                                         data back to the original mailbox. This means that you must perform a two-step
                                         merge operation. You must rename the .pst file between each step of the merge
                                         operation.


                         Messaging Dial Tone Recovery Strategy
                         If you have a large mailbox store, it may take several hours to restore the mailbox store from
                         backup. With the "Messaging Dial Tone" strategy, you can restore e-mail service more quickly to
                         users, and you can restore their previous data as it becomes available. You first reset an
                         Exchange database by removing the current database files to create a temporary, blank, "dial
                         tone" database. Users can log on to this database to send and to receive mail. New, empty
                         mailboxes are created in the "dial tone" database when users log on. Because the new mailboxes
                         have the same values for the msExchMailboxGUID attribute in the "dial tone" database as in
                         the original database, you can use the Exmerge.exe tool to transfer data between the original
                         database and the temporary “dial tone” database.


                         When the "dial tone" database is set up and is running, you can restore or repair the original
                         database in the Recovery Storage Group. When the restore or the repair operation is complete,
                         dismount both database, and then swap the database files between the original storage group
                         and the Recovery Storage Group. By doing so, users can access their previous data, but users
                         cannot access new items. To restore access to new items, use the Exmerge.exe tool to transfer
                         data from the "dial tone" database to the original database.
