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

IMPORTANT:

Click Edit Plugin Options, and configure the following settings.

NDMP Server

This option specifies the target filer name. It is only required when you want to restore data to an alternate filer. By default, it is set to the name of the original filer from which the data was backed up. Do not change the NDMP Server while restoring data to the same filer.

Direct Access Restore Mode

Select the appropriate Direct Access Restore (DAR) mode from the following:

Use Direct Access Restore if Possible: To perform a direct-access restore if the backup was direct and the mover and data server can complete DAR, select this option. If these conditions are not met, a nondirect-access restore is performed.
Use Direct Access Restore by Recovering Individual Files: To restore a directory and its file contents, select this option. When you use this option, empty directories in the saveset are ignored.
Only Do Direct Access Restore: To force a direct-access restore, select this option. It can be only used if the backup was direct and the mover and data server can complete a direct-access restore; otherwise the restore job fails.
Never Do Direct Access Restore: To perform a standard nondirect-access restore, select this option.

Incremental Restore

To recursively extract data and reconstruct the selected subtree to the state it was in at the time of backup, select this check box.

This option is equivalent to setting the environment variable EXTRACT=N. The plug-in overwrites the existing files and deletes the files that were not present at the time of backup.

Restore ACLs

To restore ACLs from the backed-up file, select this option. This option is equivalent to setting the environment variable EXTRACT_ACL=Y. You can use this option only if the Backup ACLs option was selected during backup.

IMPORTANT:

To save the settings, click OK, and then click Next.

In Job Name, specify a name for the job.
In the Target Client list, the client from which data was backed up is selected by default. Do not change this setting.
For more information about these sets, see the Quest NetVault Backup Administrator’s Guide.
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 Quest NetVault Backup Administrator’s Guide.

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.

Renaming or relocating data

When restoring a backup, you can rename the directories to create a copy of the data instead of overwriting of the existing versions. You can also relocate the data to a different volume. This procedure can be useful if the original volume is down or if you are dealing with limited bandwidth or capacity.

In the Restore Rename dialog box, configure the following option:
Click OK to close the dialog box.

Restoring data to an alternate filer

To relocate a backup to an alternate filer, use the following procedure. This procedure can be useful during a server migration or disaster recovery operation.

Before you start the restore procedure, add the target filer to the plug-in. For more information, see the Quest NetVault Backup Plug‑in for NDMP User’s Guide.

Click Edit Plugin Options, and configure the following option:
NDMP Server: This option specifies the target filer name. By default, it is set to the name of the original filer from which the data was backed up. To relocate the data to an alternate server, type the name of the target filer.
