Setting Description
Minimum life for imported backups
A piece of media is marked as “foreign” if no information for that item is available in the NetVault Database. This can occur for several reasons, for example, when a piece of media is swapped between libraries, removed from the NetVault Backup Server, or loaded on a device controlled by another NetVault Backup Server. NetVault Backup cannot process data stored in a foreign tape until you scan the tape and import the backups and backup indexes into the NetVault Database. Scanning retrieves the header information from the backup media and adds it to the NetVault Database. For more information about scanning foreign media, see Scanning a foreign tape.
The retention period for the imported data is determined by the backup life set for the savesets. If the saveset is already retired, the data is temporarily stored for 7 days. To change the default retention period, type or select a new value. The retention period is specified in number of days. Use barcodes as labels By default, NetVault Backup assigns a system-generated string as the
media label to blank media items. The string consists of the NetVault Backup Server Name, the current date, and a seed number.
To assign media barcodes as the default label for blank media during backups, select this check box.
Continuation Restore
Request Priority Boost A continuation restore request occurs when an active restore job requires additional media for completion. By default, these requests are assigned a priority level of 5 so that they are not preempted by other media requests and the active job is completed without any interruption.
To change the default setting, type or select a value from 1 through 100. 1 denotes highest priority, while 100 denotes lowest priority. A job with a

To change the default setting, type or select a value from 1 through 100. 1 denotes highest priority, while 100 denotes lowest priority. A job with a priority level of zero (0) runs as a background task.
Bulk Label Callback
Timeout The callback timeouts for bulk media labeling controls how long NetVault Backup waits for user inputs before ending these requests. By default, NetVault Backup waits for 120 seconds for user confirmation. If
confirmation is not received within the specified interval, the request is not carried out.
To change the default setting, type or select a new value. The timeout value is specified in number of seconds.
Bulk Blank Callback
Timeout The callback timeouts for bulk media blanking controls how long NetVault Backup waits for user inputs before ending these requests. By default, NetVault Backup waits for 120 seconds for user confirmation. If
confirmation is not received within the specified interval, the request is not carried out.
To change the default setting, type or select a new value. The timeout value is specified in number of seconds.
Minimum interval between reporting online capacity
This setting determines how frequently the online media status is updated on the NetVault WebUI.The default value is 10 minutes.
To change the default setting, type or select a new value. The update interval is specified in number of minutes.
Mark expired Read Only media as writable
This option prevents automatic reuse of retired read-only media. When you select this check box the read-only tag for a piece of media is automatically removed when the last saveset stored on it is retired. This allows you to re-use the media for new backups.
Days of inactivity before
an index is compressed Backup indexes stored in the NetVault Database are called Online Indexes. 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).
Table 15. General settings for Media Manager
6 Click Apply to apply the new settings and close the dialog box. 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 Backup indexes stored in the NetVault Database are called Online Indexes. 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)
Maximum characters in a media request diagnosis
By default, NetVault Backup supports a maximum of 64,000 characters in the Diagnose Media Requests for Job dialog box. To change this setting, type or select a new value. The value is specified in thousands of characters.
Lesser number of characters may result in quicker output. However, the output may be truncated and you may not get the complete information. Therefore, you should not change the default value for this option.
