NetVault Plug-in for Exchange 11.0

When using the ESE Restore Method, all databases being restored must first be dismounted using a Microsoft-approved approach or by selecting the Dismount Databases Before Restore option in the Restore and Recovery Options tab of the Restore Options tab. Failing to dismount the database before performing the restore results in either a Restore Failure or a Restore Completed with Warnings job status.


	IMPORTANT: Windows Server® 2008 supports Exchange Server 2007 SP1 or later; previous versions of Exchange 2007 are not supported. In a standard Exchange Server 2007 SP1 installation, there is an ESE client library (esebcli2.dll) in the Exchange Server Bin folder. The file version of esebcli2.dll is 8.1.240.5 for Exchange Server 2007 SP1. However, if this library is not replicated from the Exchange Bin folder to the Windows Bin folder, an older version of the .dll file might be present in the Windows Bin folder. Plug‑in for Exchange uses the ESE client library that is available in the Windows Bin folder. If the older version of the library is contained in the Windows Bin folder, a backup or restore job might fail. If a failure occurs, save a copy of the ESE client library from the Windows Bin folder to a safe location, copy the ESE client library from the Exchange Server Bin folder to the Windows Bin folder, and run the backup or restore job again.

Volume Shadow Copy Service (VSS)

During a VSS-based restore, the plug-in instructs the Exchange Store Writer to coordinate with the Exchange Information Store — on behalf of the plug-in — to prepare the system for the restore, verify the restore targets, put back the data from the backup device, and then replay the transaction logs as needed.

Copy Files Restore Method

Plug‑in for Exchange lets you restore the raw files from storage to a specific target directory. This method provides greater freedom in restoring database files, particularly when restoring files for non-traditional purposes, such as data mining or compliance auditing.

The Copy Files Restore Method does not require that you dismount databases from the Exchange Server. However, Database Recovery is not supported when using this restore method.


	NOTE: The Copy File Restore Method is required when creating a Staging Area or Target Directory to perform individual mailbox and mailbox item recovery. For more information, see the Dell Recovery Manager for Exchange User Guide.

Reviewing the Phases of the Restore Sequence

Each Exchange Server restore scenario has two distinct phases: the Restore Phase and the Recovery Phase.

Restore phase

The Restore Phase is used to transfer all the files included in a backup from storage to the local disk. This process can be done using one of the Restore Methods defined in Reviewing the available restore methods.

When performing restore sequences that include Incremental or Differential Backups, the Restore Phase is performed for each backup that is restored.

Ensure that adequate disk space is available on the volume or volumes where the databases are stored during a restore. If disk space is exhausted during the Restore Phase, the restore job fails.

Recovery phase

In the Recovery Phase, changes that were logged in the transaction log files are reapplied to the corresponding databases to bring the Exchange Server forward in time. This phase is only available when using the ESE or VSS Restore Method.

When restoring sequences of backups (as in the case of Incremental or Differential Backups), the Recovery Phase is performed one time as the final step in the restore sequence. Recovery is only performed once, regardless of the number of backups included in the restore sequence.

Restoring data using the plug-in

A standard restore procedure includes the steps outlined in the following sections:

•

Selecting data for a restore

•

Setting restore options

•

Setting security options

•

Finalizing and submitting the restore job

Selecting data for a restore

On the Navigation pane, click Create Restore Job.

On the Create Restore Job — Choose Saveset page, select Plug‑in for Exchange from the Plugin Type list.

To filter the items displayed in the saveset table further, use the Client, Date, and Job ID lists.

The table displays the saveset name (Job Title and Saveset ID), creation date and time, and size. By default, the list is sorted alphabetically by saveset name.

The following table outlines the backup-type identifiers:


Backup method	Backup type	Backup type identifier
Extensible Storage Engine	Full	ESE FULL
	Copy	ESE COPY
	Incremental	ESE INCREMENTAL
	Differential	ESE DIFFERENTIAL
Volume Shadow Copy Service	Full	VSS FULL
	Copy	VSS COPY
	Incremental	VSS INCREMENTAL
	Differential	VSS DIFFERENTIAL

In the saveset table, select the applicable item.

When you select a saveset, the following details are displayed in the Saveset Information area: Job ID, Job Title, server name, client name, plug-in name, saveset date and time, retirement setting, Incremental Backup or not, Archive or not, saveset size, and snapshot-based backup or not.

Click Next.

On the Create Selection Set page, select the data that you want to restore.

NetVault Backup lets you select from the following items for inclusion in a restore job, depending on what version of Exchange you are using:

•

Entire Information Store

•

Individual Storage Groups

•

Sets of Storage Groups

•

Individual Databases — including Mailbox Databases and Public Folder Databases

•
