Media By Groups - Overview

Scratch Pools

A scratch pool is a repository of media that are available for use. For comprehensive information on scratch pools and the default scratch pool, see Scratch Pools.

Cleaning Media

The Cleaning Media pool is the logical repository for the cleaning media in the library. For comprehensive information on cleaning media and cleaning media pools, see Cleaning Media.

Retired Media

The Retired  Media pool is the logical repository for all Deprecated media. Media is marked as Deprecated when the recycled spare media has been marked as Bad or exceeds the preset thresholds defined for the media in Media Expiration Threshold Parameters. The system determines whether a media is Deprecated during the following operations:

  • Whenever a job requires spare media from the scratch pool, the system determines whether the media has exceeded its threshold values. If the threshold values are exceeded, it is marked as Deprecated and directly moved to the Retired Media pool.
  • In the case of an active media, the system determines whether the media has exceeded its threshold values before writing to that media. If the threshold values are exceeded, an Event Message is generated indicating that the media has exceeded its threshold values. Such media are moved to the Retired Media pool until the media is recycled.
  • Bad media is moved to the Retired Media pool after the media is recycled.
  • If a cleaning media is marked bad or exceeds the preset thresholds defined for the media in the Media Expiration Threshold Parameters, it is marked as Deprecated and moved to the Retired Media pool.

You can perform the following operations on the media available in the Retired Media pool:

  • Export a media to physically remove it from the library.
  • Delete a media to remove the media information from the CommServe database. If the media you wish to delete is not already exported, the delete operation has an option to export the media before deleting it.
  • Verify the media to confirm whether the media information displayed in the CommCell Console matches the OML in the media.

Overwrite Protect Media

The Overwrite Protect Media pool is logical repository for media that should not be used for any write operations. The Overwrite Protect Media pool can be used to save media containing aged data, so that the aged data can be restored if necessary. (See Accessing Aged Data for more information.)

Note that only spare media can be moved to the Overwrite Protect Media pool. If you wish to save data from media in the Assigned Media  pool, use the Prevent Reuse option to automatically move the media to a designated Overwrite Protect media pool when the media is recycled.

Note, however, that the guaranteed way of retaining data is setting the right Data Retention Rules or using the Retain the Job option on the Storage Policy Copy.

You can perform the following operations on the media available in the Overwrite Protect Media pool:

  • Export a media to physically remove it from the library.
  • View the contents of the media. This feature can be used to view information associated with the data secured by data protection operations residing in the media.
  • Verify the media to confirm whether the media information displayed in the CommCell Console matches the OML in the media.
  • Delete the contents of the media.
  • Mark a media bad.
  • Prevent the media from being exported.
  • Update the barcode associated with the media
  • View the media properties

Foreign Media

The Foreign Media pool is the logical repository for media that are not used by the MediaAgents in this CommCell. This could be media from another CommCell or backup software. This media pool can be used to manage foreign media using Vault Tracker.

You can perform the following operations on the media available in the Foreign Media pool:

  • Export a media to physically remove it from the library.
  • Verify the media to confirm whether the media information displayed in the CommCell Console matches the OML in the media.
  • Delete the media.
  • Mark a media bad.
  • Prevent the media from being exported.
  • Erase the media
  • View the media properties

Assigned Media

The Assigned Media pool is the logical repository for all used media inside or outside the library.

You can perform the following operations on the media available in the Assigned Media pool:

  • Export the media to physically remove it from the library. After the export operation the media will be displayed both in the Assigned Media pool as well as the Exported Media pool.
  • View the contents of the media. This feature can be used to view information associated with the data secured by data protection operations residing in the media.
  • Verify the media to confirm whether the media information displayed in the CommCell Console matches the OML in the media.
  • Delete the contents of the media.
  • Mark an active media full.
  • Mark a media bad.
  • View the media properties
