Creating Target Sets

A Target Set is used to specify target device and media options for backup jobs. You can create Target Sets from the Create Backup Job page.

To create a Target Set:
1
Start the backup job wizard, and click Create New next to the Target Storage list.
2
On the Backup Job Wizard — Create Target Set page, click the corresponding button, and configure the options described in the following sections:
•
Selecting the device
•
Specifying media options
•
Configuring media sharing options
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 Target Set.

Selecting the device

To select a device for a backup job:
1
On the Backup Job Wizard — Create Target Set page, click Device Selection, and configure the following settings.
Table 25. Device Selection options for Target Set
 
Option
Description

Any Device

This option is selected by default. If you do not specify a device, NetVault Backup uses any suitable device for a job.

Specify Device

To use particular devices for a job, select this option. In the associated box, clear the check marks for the devices that you do not want to use. When you exclude a library, the associated drives are automatically excluded.

You can also use the following buttons to select or clear devices:

•
Unselect all: Clears all devices.
•
Toggle selection: Clear the selected devices and select the cleared devices.

Local Drives Only

To use only devices that are locally attached to the target client, select this check box.

 
* 
NOTE: Disk-based devices (RAS devices) are considered network-attached or non-local devices. A local device is given priority over a disk-based (RAS) device; a local VTL or SCSI device is given priority over a local NDMP filer-attached device.

If you select the Any Device option, NetVault Backup tries to find a suitable local device (local to the NetVault Backup client). To use any other device, you can set a higher media request weight for that device. For more information about media request weightings, see Configuring media request weightings.

Specifying media options

To configure media options for a backup job:
1
On the Backup Job Wizard — Create Target Set page, click Media Options, and configure the following settings.
Figure 14. Media Options dialog box
Table 26. Media Options for Target Set
 
Option
Description

Target media by

Select one of the following options:

•
Any media not in a group: This option is selected by default. To use media items that do not belong to any media group, leave this option selected.
•
Any media: To use any suitable media item regardless of its group association, select this option.
•
Specific Media ID: To use particular media items, select this option. In the list of media items, select the label for the target media.
•
Media in group: To use media items that belong to a particular media group, select this option. In the list of media items, click the group label for the target media. Media group labels are case‑insensitive.

Label Media

To automatically label blank media items during backup, select the Automatically label BLANK media check box.

By default, NetVault Backup assigns a system-generated label to blank media. The label consists of the NetVault Backup Server Name, the current date, and a seed number.

You can configure NetVault Backup to use media barcodes as the default labels. For more information, see Configuring general settings for Media Manager.

NOTE: If a piece of media that previously appeared to contain data becomes unexpectedly blank, it is marked as “suspect” to ensure that auto‑labeling does not occur for it. NetVault Backup does not permit the use of same label, whether user-specified or system-generated, to ensure that only one label is associated with a piece of media. A notification event occurs when any piece of media becomes unexpectedly blank.

Reuse media

Select the appropriate option from the following:

•
Never: This option is selected by default. To ensure that media marked for re-use are not used for backup, leave this option selected.
•
Any: To allow any suitable reusable backup media regardless of the group association, select this option.
•
With the same group label as target media: To reuse media that belong to same media group as the target media, select this option. This option can only be set if you have specified a group label for the Target media by option.
NOTE: A piece of media is automatically marked for reuse when the last saveset stored on it is retired. To manually mark a piece of media for re‑use, see Marking a tape for reuse.

Media request timeout

Type or select the amount of time NetVault Backup waits for the backup media. The timeout value is specified in number of minutes. If the required media item is not available within the specified interval, the job is automatically aborted.

The default value is zero (0). With the default setting, the job waits indefinitely until the media is provided or the job is manually aborted.

The maximum timeout period that can be set is 1440 minutes (24 hours), which ensures that current instance is aborted before NetVault Backup runs the next instance of a Daily job.

NOTE: The timeout interval for media requests cannot be less than 5 minutes. The interval is automatically set to the nearest 5 minutes, if you specify a value that is not a multiple of 5. For example, if you specify 8 minutes, the timeout value is set to 10 minutes, and if you specify 23 minutes, the timeout value is set to 25 minutes.
 
* 
NOTE: Backups to disk-based devices are stream-oriented. The concept of media does not apply to disk-based devices. The media options Target Media By, Label Media, and Reuse Media do not apply to disk-based storage devices.

If a media group contains tape media and NetVault SmartDisk devices, NetVault Backup always uses the physical or virtual tape media from that group. To write backups to a NetVault SmartDisk device, you must explicitly select the device.

Configuring media sharing options

To configure media sharing options:
1
On the Backup Job Wizard — Create Target Set page, click Media Sharing, and configure the following settings.
Table 27. Media Sharing options for Target Set
 
Option
Description

Ensure backup is the first on the target media

To write a backup at the beginning of a tape, select this check box. The data can be restored quickly if the saveset is located at the beginning of a physical tape.

Only new or blank media are eligible for backups that use this option.

NOTE: When performing multi-stream backups, do not select the Ensure backup is the first on the target media check box. If you select this check box for multi-stream backups, each data stream targets a separate piece of media to exist as the first backup on the media item. Thus, if a backup generates five streams, the job tries to obtain five blank or new media items.

Protect media from further writes after backup

To write-protect a piece of media after the backup completes, select this option.

NOTE: To mark any existing tapes as “read-only,” see Marking a tape as read-only.

Only use media with a minimum of <x> gigabytes of free space

To specify the minimum amount of space required on the target media, type or select the value. The value must be specified in GB.

 
* 
NOTE: The Media Sharing options do not apply to disk-based storage devices.
