NetVault 13.1.2 - Administration Guide

Configuring media sharing options

On the Backup Target details drawer, click Media Sharing, and configure the following settings.

Table 43. 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.

Creating Source Sets for backup jobs

Source Sets are used to specify source device options. Source Sets are required for Plug-in for Consolidation jobs, Plug-in for Data Copy jobs, and Secondary Copy jobs.You can create Source Sets from the Create Backup Job page.

To create a Source Set for backup jobs

Start the backup job wizard, and click Create New next to the Source Storage list.

On the Backup Job Wizard — Create Source Set page, click Device Selection, and configure the following settings.

Table 44. Device Selection options for Source Set
Option	Description
Any Device	This option is selected by default. If you do not specify a device type, NetVault 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 remove a library, the associated drives are automatically removed.
Local Drives Only	To use only devices that are locally attached to the target client, select this check box. NOTE: NetVault SmartDisk is considered a network-attached device or a non-local device.

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 Source Set.

Option

Description

Archive

To create an archive, select this option.

An archive cannot be used as a base for Incremental or Differential backups. When archiving data, you must always select the Full Backup type. If you select Incremental or Differential Backup type, the restore job fails.

Backup

This option is selected by default. To create a backup, use this option.

Backup Life

This option specifies how long a backup is retained.

A backup can be retained indefinitely or retired after a specified period. NetVault supports generation- and time-based retirement methods for backups. For more information about backup retirement methods, see Backup retirement.

You can specify the retirement options in the Backup Advanced Options Set. Alternatively, you can use the Change Expiry method to set or change the expiry date or generation count for existing savesets. For more information about the Change Expiry method, see Configuring saveset expiry options.

To set the Backup Life option, do the following:

•

Backup life — based on Full Backup count: To configure generation-based retirement, select the Discard After Full Backup Count option. In the associated list, type or select the maximum number Full Backups that you want to retain.

•

Backup life — based on time: To configure time-based retirement, select the Discard After option. Type or select the period, and in the associated list, select the Days, Weeks, Months, or Years option.

By default, the Backup Life option is set to Discard After and the retirement period is set to three months.

•

Force Expiry: By default, if a backup has any dependent backups, its retirement is deferred until all dependent backups are ready for retirement.

You can select this check box to retire a backup according to its retirement schedule. Forcing this behavior can cause early retirement of dependent Incremental and Differential Backups.

To apply this rule globally to all backups, you can modify the Media Manager settings. For more information, see Configuring retirement rules for dependent backups. If the Retirement Timing Control option is set to Force Always, the Force Expiry is option is used, regardless of state of this check box.

•

Retain a backup indefinitely: To retain a backup indefinitely, select the Don't Discard based on Full Backup Count and Don't Discard based on Time options.

NOTE: If you set both Discard After Full Backup Count and Discard After options for a Full Backup, the backup is retired only when both conditions are met. For example, if you set the Discard After Full Backup Count option to four Full Backups and the Discard After option to 30 days, the backup is retired after five Full Backup counts and 30 days.

NOTE: When you set time-based retirement, the time component (HH:MM) is automatically set to the job save or job submit time.

NOTE: In time-based retirement, the time component (HH:MM) does not represent the actual retirement time. It only represents the time due for backup retirement. The actual time of retirement is determined by the interval at which Media Manager scans the Media Database to identify the backups that it needs to retire. The default interval between two scans is 60 minutes. Thus, if the retirement time is set to 10:20, the backup is actually retired at 11:00. You can change this default setting in the mediamgr.cfg file. For more information, see Configuring default interval for backup retirement scans.

Offline Index After

Online backup indexes allow you to quickly scan through the contents of a saveset without loading the media. However, these indexes can increase the overall size of the NetVault Database. To manage the database size, you can delete the online indexes.

You can use different methods to delete online indexes:

•

You can configure the Offline Index After option in the Backup Advanced Options Set to automatically delete the online index for a backup after the specified period. This method is described in this section.

•

You can use the Days of inactivity before an index is offlined setting to configure a global policy for deleting online indexes after a specified period of inactivity. For more information, see Configuring Media Manager settings for backup indexes.

•

You can manually delete the online indexes for one or more backups from the Manage Backup Indexes page. For more information, see Manually deleting online indexes.

To specify the index retention period in the Backup Advanced Options set, select Offline Index After option. Type or select the length of time that you want to retain the index, and in the associated list, select the Days, Weeks, Months, or Years option.

Make Backup Immutable

To make files immutable, select this option. If you did NOT select Discard After for Backup Life, then enter a length of time in hours, days, months, or years, to keep the files before NetVault discards them. If you selected Discard After, then the immutability feature bases its file retention on this selection.

NOTE: This setting is irreversible. After you make backups immutable, you cannot make them not immutable.

NOTE: You cannot delete an immutable file until it reaches the selected length of time.

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


	NOTE: When a backup stored on a disk-based storage device (such as NetVault SmartDisk, Quest DR Series system, or Data Domain system) is retired, that backup is deleted from the device. You cannot import the deleted backup by scanning the device. NOTE: When a backup is immutable, it does not retire until it reaches the selected length of time, regardless of the backup count
