Index Storage

Edit online

The Index Storage graph displays the index storage usage.

When a host is scanned by a policy, the anomaly scan software organizes the data in the index into segments. Each segment contains information about the host and the files that are scanned. An index can contain many segments, which can no longer be needed later. You can use two options to reclaim index storage space and remove hosts that you do not want to index.

  • Reclaim index storage: The weekly process that manages older segments and removes versions of files that are no longer needed from the segments. You can set the weekly schedule for the process to run.
  • Enable unindexed hosts removal: When enabled, the daily process checks for any new backups within the specified number of days for a known host, which has had previous backups analyzed, and if newer backups do not exist, removes that host and all related data from the index. If a host is scanned but later decommissioned, eliminating the need for further scans, the host is removed from the index. In this case, the host data is still in the index but is old and no longer relevant and can be removed. You can set the schedule for the process to run every 30 to 90 days.

Go to Settings > Storage > Index Storage to view the graphical representation of the storage used by the indexing jobs, storage availability, and reset the index. Hover over the usage line to see how much storage is being used for a particular date.

Editing the index maintenance settings

You can modify the index maintenance settings from the Index Maintenance Settings section. The following settings can be modified:
  • When index storage is reclaimed
  • Enable or disable unindexed host removal
  • Modify how long to retain unindexed hosts in an index
To edit the index maintenance settings, complete the following steps:
  1. Go to the Settings > Storage > Index Storage page.
  2. Select Index Maintenance Settings.
  3. To change the time and day of reclaiming index storage space, select a new value from the Reclaim index storage field calendar.
  4. To enable or disable unindexed host removal, enable or disable Enable unindexed host removal toggle option. By default, the option is not enabled.
  5. To change how long to retain unindexed hosts in an index, select a new value from the Remove Hosts not indexed in field. The value can be set between 30 to 90 days. The default value is 60.
  6. Click Save Changes to save any changes that you made. Click Discard Changes to discard any modifications you made.
