Restoring Full and Differential Backup sequence

This example assumes that Full Backups are performed every Sunday night at 11:00 p.m. and that Differential Backups are performed Monday through Saturday at 11:00 p.m. If recovery is performed on Tuesday, Sunday’s Full Backup and Monday’s Differential Backup must be restored. If recovery is performed on Thursday, Sunday’s Full Backup followed Wednesday’s Differential Backup must be restored.

Recovering a Full and Differential Backup includes the steps outlined in the following topics:

•
Restoring the original Full Backup
•
Restoring the applicable Differential Backup
Restoring the original Full Backup
1
On the Navigation pane, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select Plug‑in for Exchange from the Plugin Type list.
3
In the saveset table, select the Full Backup saveset that served as a starting point for the applicable Differential Backup sequence, and then click Next.
4
On the Create Selection Set page, select the objects to restore.
For example, you can select the entire Information Store or only the databases that have been corrupted as detailed in Selecting data for a restore.
5
Note which items you selected.
6
Click Edit Plugin Options, and select the following options on the Restore and Recovery Options tab:
•
Verify that the Backup Type is labeled FULL.
•
In the Restore Method section, select Extensible Storage Engine (ESE) or Volume Shadow Copy Services (VSS).
•
In the Restore Options section, select Restore Files from Backup, enter the Maximum Number of Parallel Streams, and select Dismount Databases before Restore.
•
In the Recovery Options section, clear Perform Recovery. All other options should be disabled.
7
Click the Security tab, and enter the proper Authentication Details.

Restoring the applicable Differential Backup
1
On the Navigation pane, click Create Restore Job.
2
On the Create Restore Job — Choose Saveset page, select Plug‑in for Exchange from the Plugin Type list.
3
In the saveset table, select the applicable Differential Backup in the sequence, and then click Next.
4
On the Create Selection Set page, select the objects to restore.
For example, you can select the entire Information Store or only the databases that have been corrupted as detailed in Selecting data for a restore.
5
Click Edit Plugin Options, and select the following options on the Restore and Recovery Options tab:
•
Verify that the Backup Type is labeled DIFFERENTIAL.
•
In the Restore Method section, select Extensible Storage Engine (ESE) or Volume Shadow Copy Services (VSS).
•
In the Restore Options section, select Restore Files from Backup, and enter the Maximum Number of Parallel Streams.
•
In the Recovery Options section, select the following:
•
Select Perform Recovery.
•
If the most recent Differential Backup is selected for restore, select Replay Current Logs. If the Differential Backup selected for restore is not the most recent, that is, you are restoring an Exchange Server to a specific point before the last available Differential Backup job, clear Replay Current Logs.
If this option is selected, the Exchange Server scans all recent logs and updates all data to its most recent state. The Exchange Server performs this process instead of leaving the restored data at the state it was in at the time the Incremental Backup was completed.
When restoring VSS-based backups, current logs are automatically replayed. Therefore, if you want to restore up to the point of the last backup, the current logs must be deleted before the VSS Restore is performed.
•
Select Mount Databases after Recovery.
6
Click the Security tab, and enter the proper Authentication Details.
7
Complete and submit the job.
For details, see Finalizing and submitting the restore job.
On job completion, NetVault Backup finalizes the restore and recovery process and all restored data is accessible to the Exchange Server.

Renaming Storage Groups/Mailbox Databases

•
Supported Exchange Versions: 2007 and 2010
•
Supported Backup Methods: ESE and VSS (2007 and 2010)

The Plug‑in for Exchange allows you to rename a Storage Group/Mailbox Database during VSS-based restores. Renaming is useful if you do not want to overwrite the existing version and want to create a copy of the Storage Group/Mailbox Database. The following prerequisites are met before initiating the restore:

Ensure that the following prerequisites are met before initiating the restore:

•
For Exchange 2007:
•
Target Storage Group must exist: The target Storage Group must be created in the Exchange System Manager or Exchange Management Console.
•
Database names must match original: The database names in the target Storage Group must match the database names in the original Storage Group.
•
Database filenames must match original: The database filenames in the target Storage Group must match the database filenames in the original Storage Group; however, the database file path or directory for the target Storage Group can be different.
 
* 
NOTE: Due to a scripting limitation of the Windows PowerShell, the plug-in does not support the use of single or double quotation marks in Storage Group/Mailbox Database names.
•
For Exchange 2010 and later:
•
Target Mailbox Database must exist: The target Mailbox Database must be created in the Exchange System Manager or Exchange Management Console.
•
Database names must be different from the original: The name of the target Mailbox Database must be different from the name of the original database.
•
Database filenames must be different from the original: The database filenames in the target Mailbox Database must be different from the database filenames used in the original Mailbox Database.
 
* 
NOTE: Due to a scripting limitation of the Windows PowerShell, the plug-in does not support the use of single or double quotation marks in Storage Group/Mailbox Database names.

To complete the rename process, perform the following steps.

1
After the prerequisites have been met, click Create Restore Job.
2
Select Plug‑in for Exchange from the Plugin Type list.
3
Select the Storage Group/Mailbox Database to restore from the backup saveset by following the instructions outlined in Selecting data for a restore, and click Next.
4
On the Create Selection Set page, select the Storage Group/Mailbox Database that you want to rename.
5
From the Actions list, select Rename.
6
In the Rename/Relocate dialog box, enter the existing name of the target Storage Group/Mailbox Database in the Rename box, and click Ok.
The name of the Storage Group/Mailbox Database is updated to reflect the rename information in parentheses.
7
Continue with the restore procedure as explained in Setting restore options and Finalizing and submitting the restore job.
8
Open the Exchange Management Shell.
9
Run the applicable command:
•
For Exchange 2007:
Get-Mailbox -Database <SourceDatabase> |where {$_.ObjectClass
-NotMatch '(SystemAttendantMailbox|ExOleDbSystemMailbox)'}
| Move-Mailbox -ConfigurationOnly -TargetDatabase <TargetDatabase>
•
For Exchange 2010 and later:
Get-Mailbox -Database <SourceDatabase> |where {$_.ObjectClass
-NotMatch '(SystemAttendantMailbox|ExOleDbSystemMailbox)'}
| Set-Mailbox -Database <TargetDatabase>
Replace <SourceDatabase> with the name of the original database and <TargetDatabase> with the name of the destination.

Moving databases to an alternate Storage Group

•
Supported Exchange Versions: Exchange 2007
•
Supported Backup Methods: ESE and VSS

With the restore rename functionality, you can move a database to an alternate Storage Group.

 
* 
IMPORTANT: The plug-in does not support the relocation of database file paths. Use the Exchange Management Console or the Exchange System Manager to relocate a database file path. You can find complete instructions in the relevant Exchange documentation. In addition, see How to Move a Storage Group Path at: http://technet.microsoft.com/en-us/library/bb125252.aspx

You cannot use the database rename feature to rename a database in the same Storage Group.

You cannot restore a database to an alternate Storage Group if the same database has already been restored to a different database in that same Storage Group.

If the source Storage Group has multiple databases, you cannot use a single restore job to restore the multiple databases to separate Storage Groups. You can move one database to a Storage Group in the first Restore job and move the next database to a different Storage Group in a subsequent Restore job.

Ensure that the following prerequisites are met before initiating the restore:

•
Target Storage Group must exist: The target Storage Group must be created in the Exchange System Manager or Exchange Management Console.
•
Database must exist: The target database must be created in the Exchange System Manager or Exchange Management Console.

To move a database to an alternate Storage Group, perform the following steps.

1
After the prerequisites have been met, click Create Restore Job.
2
Select Plug‑in for Exchange from the Plugin Type list.
3
Select the Storage Group to restore from the backup saveset by following the instructions outlined in Selecting data for a restore, and click Next.
4
On the Create Selection Set page, select the Storage Group.
5
From the Actions list, select Rename.
6
In the Rename/Relocate dialog box, enter the existing name of the target Storage Group in the Rename box, and click Ok.
The name of the Storage Group is updated to reflect the rename information in parentheses.
7
On the Create Selection Set page, expand the Storage Group, and select the database being moved.
8
From the Actions list, select Rename.
9
In the Rename/Relocate dialog box, enter the existing name of the target database in the Rename box, and click Ok.
The name of the database is updated to reflect the rename information in parentheses.
10
Continue with the restore procedure as explained in Setting restore options, ensuring that the Set 'This Database Can Be Overwritten by a Restore' option is selected for ESE-based restores, and Finalizing and submitting the restore job.
