Restore Exchange Data using ProxyHost
Before You Begin
- Review the general and agent-specific restore requirements accessed from
Restore Backup Data prior to performing
any restore operation.
- For ProxyHost clients to which you are restoring Exchange data, the Exchange
log files must be deleted before beginning the restore operation. When an Exchange
database and transaction log are restored, only that portion of the transaction
log that existed at the time of the backup is overwritten. Log files that were
created after the backup still exist, but they are not associated with the restored
transaction log. The presence of these unrelated files within the transaction
log causes the backup to fail in the truncating log phase. To prevent this from
occurring, you must manually delete Exchange log files before using the ProxyHost
iDataAgent to restore Exchange data.
Select the desired procedure:
Restore Exchange
2000 data to the production server
Restore
Exchange 2000 data by Synchronizing the BCV group
Restore Exchange
2003 data to the production server
Supported Snapshot Environments:
- EMC TimeFinder (TEIM)
- Compaq EVM
- EMC SnapView 1.0 or 2.0
- QSnap for Windows
Required Capability: See
Capabilities and Permitted Actions
To restore Exchange 2000 data to the
production server:
- Dismount Exchange stores and manually truncate all the log files.
-
Perform any ProxyHost restore procedure.
NOTES
- From the Restore Options (General) dialog box, you must
select the Unconditional Overwrite option.
- When the restore has successfully completed:
- If you restored the KMS database, make sure that you stop and then re-start
the Microsoft Exchange Key Management Service.
- If you restored the SRS database, make sure that you stop and then re-start
the Microsoft Exchange Site Replication Service.
- Mount the Exchange stores.
Supported Snapshot Environments:

To
restore Exchange 2000 data by Synchronizing the BCV group:
-
Perform any ProxyHost restore procedure.
NOTES
- From the Restore Options (General) dialog box, you must
select:
- the backup host as the destination machine
- the Unconditional Overwrite option
- When the restore has successfully completed on the backup host, dismount
all Exchange Services that will be restored.
- On the backup host, run the BCV restore command to synchronize the data
from the backup host to the primary devices. The restore command will differ
depending on which snapshot engine you are using; refer to the manufacturer’s
documentation for instructions on synchronizing a BCV/clone with the primary
volume.
- When the synchronization has successfully completed, mount the Exchange
stores.

To restore Exchange 2003 data to the
production server:
- Dismount Exchange stores and manually truncate all the log files.
-
Perform any ProxyHost restore procedure.
NOTES
- From the Restore Options (General) dialog box, you must
select the Unconditional Overwrite option.
- When the restore has successfully completed:
- If you restored the KMS database, make sure that you stop and then re-start
the Microsoft Exchange Key Management Service.
- If you restored the SRS database, make sure that you stop and then re-start
the Microsoft Exchange Site Replication Service.
- Mount the Exchange stores.
Restore SQL2000 Data using ProxyHost
Select the desired procedure:
Restore single/multiple SQL2000 databases to the production server in one TSIM restore
command
Restore SQL2000
databases to the production server
Restore SQL2000
databases by Synchronizing the BCV group
Supported Snapshot Environments:
Before You Begin:
- EMC TimeFinder for SQL Integration Module (TSIM) has two restore types,
automatic and manual. The automatic restore can be completed in one step, unless
it is a standby restore, and can be covered by one script. This script can also
be used for Post Restore. The manual restore is broken into multiple steps which
can be found in the EMC ResourcePak documentation.
- Backed up data should be restored to the BCVs. In order to synchronize with
the primary volumes of the production server, the user will have to manually
run specific TSIM restore commands. These commands are included in the EMC ResourcePak
for Windows.
Required Capability: See
Capabilities and Permitted Actions
To
restore single/multiple SQL2000 databases to the production server in one TSIM restore
command:
- Restore data/log file system to backup host.
- Run the TSIM restore command to restore database.
- Split the BCV pair.
Since each tsimsnap_restore command can only
specify one database, Steps 2 and 3 have to be repeated again in the same script
file to restore multiple databases. Follow the steps below to perform this operation:
- Run TSIM restore command to restore database1.
- Split the BCV pair1.
- Run TSIM restore command to restore database2.
- Split the BCV pair2.
It will take a moment for the BCV group to update the status flag to "RESTORED".
The "RESTORED" flag is required for the splitting to run.
To improve performance, a flag query command can be inserted between Step 1 and
Step 2 (also Step 3 and Step 4). In that way Step 2 or Step 4 will not start until
the "RESTORED" flag is received by query command.
The final tsim_restore script structure will
contain the following sections:
- Run TSIM restore command to restore database1.
- Wait for the BCV group1 to update the status flag to "RESTORED".
- Split the BCV pair1.
- Run TSIM restore command to restore database2.
- Wait for the BCV group2 to update the status flag to "RESTORED".
- Split the BCV pair2.
Supported Snapshot Environments:
- Compaq EVM
- EMC SnapView 1.0 or 2.0
- QSnap for Windows
Before You Begin:
- For both EMC SnapView and Compaq EVM snapshot systems, the SQL2000 database
which was selected for restore must be manually detached prior to the restore.
The restore does not use SQL2000 APIs, it instead is just a file system restore.
If the database is not detached before the restore, a reboot will be enforced
after the restore has completed.
- The database freeze/thaw utility does not support file group level, therefore
restores cannot be executed on individual file groups.
- Only data that was frozen and backed up should be restored.
Required Capability: See
Capabilities and Permitted Actions
To
restore SQL2000 databases to the production server:
- Detach all SQL2000 databases being restored.
-
Perform any ProxyHost restore procedure.
NOTES
- From the Restore Options (General) dialog box, you must select
the Unconditional Overwrite option.
- When the restore has successfully completed, re-attach all restored SQL2000
databases.
Supported Snapshot Environments:
- Compaq EVM
- EMC SnapView 2.0

To
restore SQL2000 databases by Synchronizing the BCV group:
-
Perform any ProxyHost restore procedure.
NOTES
- From the Restore Options (General) dialog box, you must select:
- the backup host as the destination machine
- the Unconditional Overwrite option
- When the restore has successfully completed on the backup host, detach the
SQL2000 databases that will be restored.
- On the backup host, run the BCV restore command to synchronize the data
from the backup host to the primary devices.
- When the synchronization has successfully completed, re-attach the SQL2000
databases.
