Configuring retirement rules for dependent backups

By default, the retirement of backups from a backup series is deferred until all dependent backups are ready for retirement. The backups are retired only when the last dependent backup is retired. You can use the Retirement Timing Control setting to modify this behavior and force removal of backups according to their retirement schedule.

To configure the retirement rules dependent backups:
1
In the Navigation pane, click Change Settings.
2
On the Configuration page, click Server Settings.
3
Under Services, click Media Manager. In the Media Manager dialog box, under General Settings, configure the following setting:
•
Retirement Timing Control: You can use the following rules to retire dependent backups:
•
Force Always: When this rule is applied, a backup is removed when it reaches its retirement time. As a result, all backups from an Incremental Backup Series or a Differential Backup Series are retired when the first backup is retired. Forcing this behavior can cause early retirement of dependent Incremental and Differential Backups.
•
Keep Duplicates with Dependents: This rule specifies the retirement behavior of Duplicate Backups. When this rule is applied, Duplicates with dependents are retired only after all dependent backups have reached their retirement date. The Duplicate Backups are marked for removal according to the retirement schedule, but the removal is deferred until all dependent backups are ready for retirement.
•
Allow Duplicates with Dependents to Retire: This rule specifies the retirement behavior of Duplicate Backups. When this rule is applied, Duplicates with dependents are removed when their retirement date is reached only if the original backups or other copies are available for these backups. In the absence of the original backup or other copies, the Duplicate Backups are marked for deletion, and removed when the last dependent backup is retired.

On the Configuration page, click Server Settings.
3
Under Services, click Media Manager. In the Media Manager dialog box, under General Settings, configure the following settings.
 
Table 137. Device settings controlled by Media Manager
Setting
Description

Do not describe device activity in device window

Select this check box to stop status updates on the Device Activity page. It may help reduce the load on the NetVault Backup Server when several backup devices are added to the server.

Do not display drives that are available but not active

Select this check box to hide the offline devices on the Device Activity page.

Only check available drives and media when processing a media request

Select this check box to only check for available drives and media when a media request is received. It can be useful in large environment to reduce the network traffic generated by automatic checks. However, it may cause a delay in job startup when several jobs are started at the same time.

Only check available drives when processing a media request

Select this check box to only check for available drives when a media request is received.

Only check available media when processing a media request

Select this check box to only check for available media when a media request is received.

Do not issue Prevent/Allow Media Remove commands to drives

During backup and restore operations, the Media Manager issues PREVENT/ ALLOW MEDIUM REMOVAL SCSI commands to move a tape to or from a drive. If your library software can handle tape removal or ejection by itself and does not require any explicit commands to be sent to the drive, you can select this check box. When this check box is selected, the Media Manager skips the PREVENT/ALLOW MEDIUM REMOVAL SCSI commands during device operations.

Do not open a device if the serial number has changed

Select this check box to stop issuing commands to a device whose serial number has changed since its last configuration for NetVault Backup.

Unavailable device retry interval

Type or select the interval at which NetVault Backup tries to locate unavailable devices. The retry interval is specified in minutes. The default value is 30 minutes.

Allow library modification when jobs are running

Select this check box to allow a user to modify the library settings while it is in use.

Do Not Scan Unknown Media

When you add tapes to a library, and close the door (or restart the library), NetVault Backup takes inventory by reading the media barcodes. If NetVault Backup cannot find the barcode for a piece of media, it marks that tape as “UNKNOWN.” NetVault Backup loads each unknown tape into one of the drives to scan for backups and on-tape indices. On large systems, this process can increase the burden on the drive resources. If you do not want to scan unknown tapes and leave them as “UNKNOWN,” select this check box.

This setting applies to all new libraries that are added to the NetVault Backup Server. It does not change the setting for existing libraries. To apply this setting to an existing library, you must remove the library and re-add it.

Configuring Media Manager settings for backup indexes

To configure Media Manager settings for backup indexes:
1
In the Navigation pane, click Change Settings.
2
On the Configuration page, click Server Settings.
3
Under Services, click Media Manager. In the Media Manager dialog box, under General Settings, configure the following settings.
 
Table 138. Index-related settings
Setting
Description

Days of inactivity before an index is compressed

The online indexes are automatically compressed after 30 days of inactivity. To change the default inactivity period for index compression, type or select the new value.

To disable automatic compression of online indexes, set this option to zero (0).

Hours between scans for indexes to be compressed

This setting determines the interval at which the Media Manager scans the Media Database to identify backup indexes that can be compressed. The default value is 12 hours. To change the default interval, type or select a new value.

To disable Media Manager scans for index compression, set this option to zero (0).

Maximum number of indexes to be compressed/ uncompressed/offlined at a time

This setting determines the maximum number of backup indexes that can be simultaneously compressed, decompressed, or taken offline. The default value is 200 indexes. To change the default setting, type or select a new value.

Minimum Space For Index Decompression

The compressed backup indexes are automatically decompressed when you try to browse or restore the corresponding saveset. The minimum amount of space for index decompression is set to 500MB by default. This space is reserved on the drive or partition on which the NetVault Database resides. To change the minimum space for index decompression, type or select the new value. The space requirement is specified in MB.

A decompression request fails in the following circumstances:

•
The available space on the target drive or partition is less than the minimum required space.
•
The specified amount of free disk space is not available on the target drive or partition after index decompression.
When NetVault Database receives a decompression request, it reads the index header to determine its decompressed file size. The request is not completed if after decompression the free disk space on the target drive or partition would be less than the specified amount.

If the decompression request fails, an error message is displayed. If the request was issued manually, the message is displayed on the Create Restore Job page. When index decompression is performed automatically, the message is displayed on the View Logs page.

Days of inactivity before an index is offlined

To automatically delete online indexes after a specified period of inactivity, type or select the value. The inactivity period is specified in number of days. The default value is zero (0), which disables automatic deletion of online indexes.

Hours between scans for indexes to be offlined

This setting determines the interval at which the Media Manager scans the Media Database to identify backup indexes that can be taken offline. The default interval is 24 hours. To change the default interval, type or select a new value.

To disable Media Manager scans for online index deletion, set this option to zero (0)

Life Of Index When Loaded From Offline

The nvrestore CLI utility automatically imports an offline index if it is needed for a restore job.

This setting determines how long the indexes imported by the nvrestore utility are retained in the NetVault Database. The default value is one (1) day. To change the default setting, type or select the number of days you want to retain the index. This value must be specified in number of days.
