About managing online indexes

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 or compress the online indexes.

The following sections provide a brief description of the methods that are available for deleting and compressing online indexes:

Deleting online indexes

You can use the following methods to delete the online indexes for backups:

•
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. For more information, see Setting backup retirement options.
•
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 manually delete the online indexes for one or more backups from the Manage Backup Indexes page. For more information, see Manually deleting online indexes.

The indexes for the savesets can be loaded from the backup media if required.

 
* 
NOTE: Deleting a backup index is not the same as retiring a backup.

When a backup is retired, NetVault Backup discards all information about it from the NetVault Database. When you scan the media to retrieve the index for a retired saveset, it is loaded as a new index in the NetVault Database. When the online indexes are deleted, NetVault Backup still retains some information about the saveset. This information allows NetVault Backup to quickly reload the saveset index from the backup media.

Compressing online indexes

Online indexes are automatically compressed after 30 days of inactivity. You can modify the Days of inactivity before an index is compressed setting to customize this policy. For more information, see Configuring Media Manager settings for backup indexes.

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

Manually deleting online indexes

You manually delete the online indexes for one or more backups from the Manage Backup Indexes page.

1
In the Navigation pane, click Create Restore Job, and then on the Choose Saveset page, click Manage Indexes.

Loading offline indexes
