NetVault Plug-in for Exchange 11.3

Extensible Storage Engine (ESE): To restore selected data using the ESE method, which allows for the recovery of Full, Differential, and Incremental Backup types, select this option. For more information, see Extensible Storage Engine (ESE) Restore Method.

•

Copy Files to Target Directory Only: Select this option if you want to restore the raw files from storage to a specific target directory. When choosing this method, database recovery is not available. When restoring using this method, you do not have to dismount databases from the Exchange Server before the start of the restore job.

•

Volume Shadow Copy Service (VSS): (available only for VSS-based backups) Select this option to restore selected data using the VSS method, which allows for the recovery of Full, Differential, and Incremental Backup types. For more information, see Volume Shadow Copy Service (VSS) backup method.

•

Restore Options: Select the applicable options:

•

Restore Files from Backup: This option is selected by default to restore the files selected in a backup set. If the Perform Recovery (Enable Only on Last Step in Restore Sequence) option was not selected for the last restore job in a restore sequence, run an additional restore job. This job should have the same backup saveset selected, the Restore Files From Backup option cleared, and the Perform Recovery (Enable Only on Last Step in Restore Sequence) option selected. With these options set, NetVault Backup performs the recovery without re-transferring the data from the backup media to the Exchange Server.

•

Temporary Directory Used During Restore: (for restored log files on ESE-based backups only) Transaction log and patch files are stored in a temporary location during the restore and recovery process. In this field, specify an empty temporary directory for this restore job.


	IMPORTANT: Ensure that the temporary directory is empty. Failing to do so can cause restore jobs to fail with “Restore Environment Information Corrupted” errors.

•

Maximum Number of Parallel Streams: Specify the maximum number of parallel restore streams that to use during the restore. By default, this field displays the maximum number that is allowed based on the version and edition of Exchange Server that was used to generate the backup.

•

Dismount Databases before Restore (Not Recommended for Restores to Recovery Storage Groups): To dismount the databases that have been selected for restore automatically before actually performing the restore, select this option. All databases in selected Storage Groups are dismounted when restoring VSS-based backups. Also, databases in RSGs are not dismounted when this option is selected.

•

Set ‘This database can be overwritten by a restore’ Flag for Databases (Not Required for ESE Restores to Original Database): To restore all databases involved in the restore operation automatically and eliminate the requirement to use an Exchange utility for this operation, select this option. If you do not select this option, Quest recommends that you use the Exchange Management Console, Exchange System Manager, or Exchange Management Shell to set the Overwrite Permissions to ensure a successful restore.

IMPORTANT: Selecting This database can be overwritten by a restore has the following limitations:

•

When an RSG is configured for a database, the overwrite permission is not set for the databases in the RSG. Quest recommends that you do not select this option if the restore location is redirected to an RSG.

•

When the restore job has multiple databases in multiple Storage Groups, the overwrite permission is set for all the databases.

•

When you rename a Storage Group, the overwrite permissions are set for all databases in the target Storage Group.

•

When you rename databases, the overwrite permissions are set for the target databases.

•

Suspend Storage Group Replication before Restore: (only available for Exchange 2007) Select this option to disable replication automatically to all Storage Groups that have replication enabled for LCR and CCR.

•

Update Storage Group Replication after Recovery (Deletes Existing Files and Resumes Replication): (only available for Exchange 2007 LCR environments) Select this option to update the replication data for LCR automatically. After the existing replicated database files have been deleted, the replication is updated by copying the new database and log files. This process deletes the existing replicated database and log files. After the restore job has been completed with this option, the status in the Exchange Management Console should be Healthy.


	NOTE: After the Update Storage Group Replication after Recovery has completed successfully, the Storage Group Copy Status restored in the Exchange Management Console might show Initializing instead of Healthy. However, this status is not a problem because the Copy Status will change to Healthy after a new log file is generated for the active Storage Group.

•

Recovery Options: Select the applicable options:

•

Perform Recovery (Enable only on Last Step in Restore Sequence): Select this option when performing the last job of a restore sequence. If the restore sequence only includes a Full Backup, select this option for the Full Backup. If the restore sequence includes Incremental or Differential Restores, select this option when restoring the last backup in the restore sequence. This option finalizes the restore process after completion of the restore job for which it was selected, that is, the Exchange Server is alerted to perform necessary recovery tasks. All other options in the Recovery Options section are disabled unless this option is selected.


	IMPORTANT: When the Perform Recovery option is used with the Mount Databases after Recovery option, NetVault Backup may not automatically remount all databases included in the restore, after the recovery completes. The Storage Groups that the selected databases belong to can be mounted using the Exchange Management Console (2007) utility. For information about remounting stores, see the relevant Exchange documentation.

•

Verify Recovery Completion: (ESE restores only) Select this option to let the recovery process, which includes replaying the restored log files, complete during the duration of the NetVault Backup Restore job. This option ensures that the status of the Restore job reflects bringing the Mailbox Databases into a consistent state and mounting the databases. Clearing this option ends the NetVault Backup Restore job after the files have been restored to Exchange Server and recovery has been initiated; however, the restore job status does not accurately reflect the status of the databases and the recovery. Therefore, log in locally to the target Exchange Server and verify the status of any restored data.

•

Replay Current Logs: (automatic for VSS-based backups) Select this option to instruct the plug-in to request that the target Exchange Server access additional transaction log files that were generated after the point at which the backup was taken. After the transaction log files have been accessed, they are applied during the Exchange Server’s recovery operations, that is, after data restore is complete, to bring applicable databases to their most recent state.


	IMPORTANT: If the Replay Current Logs option is cleared for ESE-based backups, the current transaction logs are not applied during the recovery phase. This selection results in the loss of all data that is new or has been changed since the time of the backup. When restoring VSS-based backups, current logs are automatically replayed. Therefore, if you want to restore up to the point of the last backup, delete the current logs before the VSS Restore is performed.

•

Delete Temporary Log Files after Recovery: (selected by default) Leave this option selected to delete temporary files and temporary log and patch files from the directory in the Temporary Directory for Restored Log Files field after the recovery process is completed. Clearing this option will retain the log and patch files after the recovery process is completed


	IMPORTANT: The Delete Temporary Log Files after Recovery option should be selected in nearly all cases. If this option is not selected, subsequent restores that use the same directory for temporary files may result in restore failures in which Exchange reports incomplete, incongruous, or out-of-sequence log files and may result in database errors.

•

Mount Databases after Recovery: (selected by default) This option can be selected to mount the dismounted databases within the databases automatically after the restore completes. Quest recommends that you leave this option selected; otherwise, manually mount the databases after completion of the restore to bring it back online.

Setting restore and recovery options for Exchange 2010 and later

On the Create Selection Set page, click Edit Plugin Options, and configure the following parameters on the Restore and Recovery Options tab:

•

Restore Method: Select one of the following:

•

Volume Shadow Copy Service (VSS): To perform the restore of selected data using the VSS method, which allows for the recovery of Full, Differential, and Incremental Backup types, select this option. For more information, see Volume Shadow Copy Service (VSS) backup method.

•

Restore Options: Select the applicable options:

•

Target Directory: If you selected the Copy Files to Target Directory Only option, update the path for the target if you do not want to use the default.


	IMPORTANT: Ensure that the temporary directory is empty. Failing to do so can cause restore jobs to fail with “Restore Environment Information Corrupted” errors.

•

Maximum Number of Parallel Streams: Specify the maximum number of parallel restore streams to use during the restore. By default, this field displays the maximum number that is allowed based on the version and edition of Exchange Server that was used to generate the backup.

•

Dismount Databases before Restore (Not Recommended for Restores to Recovery Storage Groups): To dismount the databases that have been selected for restore automatically before actually performing the restore, select this option. All databases in selected Mailbox Databases are dismounted when restoring VSS-based backups. Also, databases in RSGs are not dismounted when this option is selected.

•

IMPORTANT: Selecting This database can be overwritten by a restore has the following limitations:

•

When an RDB is configured for a database, the overwrite permission is not set for the databases in the RDB. Quest recommends that you do not select this option if the restore location is redirected to an RDB.

•

When you rename a Mailbox Database, the overwrite permissions are set for all databases in the target Mailbox Database.

•

When you rename databases, the overwrite permissions are set for the target databases.

•

Suspend database Replication before Restore: (only available for DAG deployments) Select this option to disable database copying automatically for all Mailbox Databases that have DatabaseCopy enabled for DAG.

•

Update database Replication after Recovery (Deletes Existing Files and Resumes Replication): (only available for DAG deployments) Select this option to update database copying for DAG automatically. After the existing files of the database copy have been deleted, the database copy is updated by copying the new database and log files. This step deletes the existing database copy and log files. After the restore job has been completed with this option, the status in the Exchange Management Console should be Healthy. Updating a database copy might take a significant amount of time depending on the size of the database and the network bandwidth and latency.


	NOTE: After the Update Database Replication after Recovery has completed successfully, the Mailbox Database Copy Status restored in the Exchange Management Console might show Initializing instead of Healthy. However, this status is not a problem because the Copy Status will change to Healthy after a new log file is generated for the active Mailbox Database.

•

Recovery Options: Select the applicable options:

•

Perform Recovery (Enable only on Last Step in Restore Sequence): Select this option when performing the last job of a restore sequence. If the restore sequence only includes a Full Backup, select this option for the Full Backup. If the restore sequence includes Incremental or Differential Restores, select this option when restoring the last backup in the restore sequence. This option finalizes the restore process after completion of the restore job for which it was selected, that is, the Exchange Server is then alerted to perform any necessary recovery tasks. All other options in the Recovery Options section are disabled unless this option is selected.


	IMPORTANT: When restoring VSS-based backups, current logs are automatically replayed. If you want to restore up to the point of the last backup, delete the current logs before the VSS Restore is performed.
