Restoring a standalone Full Backup

Restoring a single Full Backup is seen as a restore sequence by the Plug‑in for Exchange. Therefore, you must follow these steps to restore a standalone Full Backup and ensure that its recovered data is suitable for use by Exchange.

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 item, 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 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, select Perform Recovery, and then select Mount Databases after Recovery. If you are using the VSS Restore Method, verify that Verify Recovery Completion, Replay Current Logs, and Delete Temp Log Files after Recovery are also selected.
7
Click the Security tab, and enter the proper Authentication Details.
8
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.

Restoring Incremental Backup sequence

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

Recovering a sequence of Incremental Backups includes the steps outlined in the following topics:

•
Restoring the original Full Backup
•
Restoring all intermediary Incremental Backups
•
Restoring the final Incremental Backup

•
In the Restore Options section, select Restore Files from Backup, and enter the Maximum Number of Parallel Streams.
•

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.
8
Repeat Step 1 through Step 7 for all additional Incremental Backups in the order they were performed except for the last Incremental in the sequence.
Specific settings must be made for the last Incremental in the sequence; these settings are covered in the following topic.
Restoring the final Incremental Backup
1
With all previous restores successfully completed, including the original Full and subsequent Incrementals, click Create Restore Job on the Navigation pane.
2
On the Create Restore Job — Choose Saveset page, select Plug‑in for Exchange from the Plugin Type list.
3
In the saveset table, drill down to the last Incremental Backup saveset in the sequence, and then click Next.
4
On the Create Selection Set page, see the data items that were restored in all previous Incremental Backup restore jobs, and select the same items for the 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 INCREMENTAL.
•
In the Restore Method section, 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.

If recovery is performed on Thursday, Sunday’s Full Backup followed Wednesday’s Differential Backup must be restored.

Additional guidelines for restoring a DAG

Whether you are restoring a Full Backup, Incremental Backup, or Differential Backup for a DAG, there are two options on the Restore and Recovery Options tab that you can select or clear depending on where you are in the restore process.

•
Suspend database Replication before Restore: If this is the first restore that you are performing in the process of recovering a DAG environment, you must select this option. This ensures that replication is suspended and recovery continues.
•
Update database Replication after Recovery (Deletes Existing Files and Resumes Replication): If this is the last restore that you are performing in the process of recovering a DAG environment, you must select this option. This ensures that replication resumes and recovery continues.
