Creating Restore Advanced Options Sets

A Restore Advanced Options Set is used to specify restore type, pre- and post-script, and other advanced options. You can create a Restore Advance Options Set from the Create Restore Job page.

To create a Restore Advanced Options Set:
1
Start the restore job wizard, and click Create New next to the Advanced Options list.
2
Configure the options described in the following sections:
•
Setting restore type
•
Specifying additional options
•
Configuring pre- and post -scripts for restore jobs
•
Configuring user-defined events for restore jobs
3
Click Save, and in the Create New Set dialog box, type a name for the set.
The set name can contain alphanumeric and non-alphanumeric characters, but it cannot contain non‑Latin characters. On Linux OS, the name can have a maximum of 200 characters. On Windows OS, there is no length restriction. However, a maximum of 40 characters is recommended on all platforms.
Click Save to save the Restore Advanced Options Set.

Setting restore type

To specify the restore type:
1
On the Advanced Options page, click Restore Type, and select one of the following options.
 
Table 65. Restore type
Option
Description

Restore from selected backup

This option is selected by default. To restore data from the selected backup, leave this option selected.

Restore from latest backup

Select this option to restore data from most recent backup that was performed using a particular Backup Selection Set regardless of which saveset you use to create the restore job.

The following example illustrates the difference between these two options:
a
Create a test directory and create a Backup Selection Set “SelectionSet-1” to back up the test directory.
b
Create a file named “first.txt” in the test directory.
c
Perform a Full Backup (TestBackup1) using “SelectionSet-1.”
d
Delete “first.txt” and create a file named “last.txt” in the test directory.
e
Perform a second Full Backup (TestBackup2) using “SelectionSet-1.”
f
Restore TestBackup1 using the Restore from selected backup option. This job restores the file “first.txt.”
g
Restore TestBackup1 using the Restore from latest backup option. This job restores the file “last.txt.”
2
Click Set to save the settings and close the dialog box.

Specifying additional options

To specify additional options for a restore job:
1
On the Advanced Options page, click Additional Options, and configure the following option:
•
Use Network Compression: To use network compression while transferring data over the network, select this check box. The data is compressed on the server or client to which the source device is attached before being transferred over the network. On the target client, the data is decompressed before being restored to the original or alternate location.
Network compression does not work for the following types of jobs:
•
Restores from NetVault SmartDisk
•
Restores from devices attached to NDMP-based NAS filers
•
Restores performed using the Plug-in for NDMP, Plug-in for NetWare, and NetVault Bare Metal Recovery products

Click Set to save the settings and close the dialog box.

Configuring pre- and post -scripts for restore jobs

You can use the pre- and post-script options to run user-defined scripts before a job starts or after a job completes. You can use these scripts to perform tasks such as dismounting or shutting down a database before the job starts or mounting or starting the database after the job completes.

Before configuring pre- or post-scripts, review the following information:

•
The script should be an executable file, for example, “.bat” files on Windows and “.sh” files on Linux.
•
The script file should reside on the target client. It should be available in the scripts directory under the NetVault Backup installation directory.
•
The pre- and post-scripts can contain run-time parameters. These parameters are stored in the environment variable NV_USER_ARG. You can also use other NetVault Backup environment variables in the scripts. For a list of available environment variables, see Environment variables in NetVault Backup.
•
NetVault Backup provides two predefined script files that can be used as post-scripts:
•
psmail: Use this script to send job completion status to the specified email addresses.
•
psmail_logs: Use this script to send job completion status and job logs to the specified email addresses.
On Linux and UNIX, the predefined scripts do not any filename extension. On Windows, the scripts have the filename extension “.bat.” To run these scripts, specify the following in the Post Script box:
•
Linux and UNIX: psmail or psmail_logs
•
Windows: psmail.bat or psmail_logs.bat
To specify pre- and post -scripts:
1
On the Advanced Options page, click Pre & Post Scripts, and configure the following settings.
 
Table 66. Pre and post script options for restore jobs
Option
Description

Pre Script

This option allows you to run a user defined script before a job starts. You can use this script to perform any pre -restore preparation, like dismounting or shutting down a database.

To run a pre -script, do the following:

•
In the Pre Script box, specify the script filename.
•
In the User Parameter box, provide the values for the run -time parameters. The value should be valid and conform to its usage in the script. NetVault Backup does not perform any validity checks for the user parameters.

Post Script

This option allows you to run a user-defined script after a job completes. You can use this script to perform any post restore processing, such as mounting or starting a database after a job completes.

To run a post -script, do the following:

•
In the Post Script box, specify the script filename.
•
In the User Parameter box, provide the values for the run-time parameters. The value should be valid and conform to its usage in the script. NetVault Backup does not perform any validity checks for the user parameters.
