Option
Description

NDMP Server

The name of the server from which the data was backed up is displayed in this field. Do not change this default value.

Direct Access Restore Mode

The Mirapoint Message Server does not support DAR. Therefore, do not change the default selection for this option. The restore job fails if you change the default selection.

Incremental Restore

Select this option when restoring dump levels 1 through 9.

6
Click OK to save the settings, and then click Next.
7
In Job Name, specify a name for the job.
Assign a descriptive name that allows you to easily identify the job for monitoring its progress. The job name can contain alphanumeric and non-alphanumeric characters, but it cannot include non-English characters. There is no length restriction. However, a maximum of 40 characters is recommended on all platforms
8
In the Target Client list, the client from which data was backed up is selected by default. Do not change this setting.

Select or create the Schedule Set, Restore Source Set, and Advanced Options Set. For more information about these sets, see the Dell NetVault Backup Administrator’s Guide.

Click Submit to submit the job for scheduling.
You can monitor the job progress from the Job Status page and view the logs from the View Logs page. For more information about these functions, see the Dell NetVault Backup Administrator’s Guide.

Post-restore procedures

On completion of the restore procedure, perform the following steps:

•
Merge the restored emails into existing emails. Refer to the relevant Mirapoint documentation for instructions.
•
If you selected /usr/store to restore the entire saveset, reboot the server.

Restoring Incremental Backups

The incremental restores build on each other. To restore an Incremental Backup, you must have all the backups from Level-0 through the last backup in the backup sequence that you want to restore.

To restore an Incremental Backup
1
Restore the Full or Level 0 Backup. For more information, see Restoring data using the plug-in.
2
Restore each Incremental Backup in the backup sequence, starting with the lowest-level backup and going to the last backup that you want to restore (that is, in the same order in which they were created). For each dump level, follow the steps outlined in the section Restoring data using the plug-in.
 
* 
IMPORTANT: All NDMP backups are effectively snapshots of the volume. When you restore a dump backup in an increment series, it restores all the data in the saveset. At the same time, it deletes the files present on the filer, but not available in that saveset. Thus, it reconstructs the subtree as it was at the time of backup.

Searching for files in savesets

The Search option on the Create Restore Job — Choose Saveset page allows you to find specific files or data items without opening any savesets or browsing through their contents. You can use filenames or regular expressions to find the data items that you want to restore.

To search for data items in savesets
1
On the Create Restore Job — Choose Saveset page, click Search.
2
In the Search for files in savesets dialog box, configure the following options:
•
Search String: Type the search string.
•
Regular expression search: To use POSIX (Portable Operating System Interface for Unix) regular expressions in the Search String box, select this check box.
•
Case sensitive: To perform a case-sensitive search, select this check box.
3
Click Search. On the Search Results page, you can view the savesets that contain the specified files or data items.
4
Select the items you want to restore. You can only restore items from one saveset. Click Next.
5
Complete Step 5 through Step 10 in the section Restoring data using the plug-in.
