Dell NetWorker 19.9 Administration Guide

Reduce the size of the media database size

Use one or more of the following methods to reduce the size of media database on the NetWorker server.

• Remove volumes that contain recyclable save sets from the NetWorker inventory. Removing volume-based entries from the online indexes provides details.

  When you remove a volume from the media database, NetWorker removes the entries that are associated with that volume from the media database and the client file index for the client. If you select this option, you can use the scanner command to recover the data on the volume, if NetWorker has not relabeled the volume.

  NOTE:You gain very little disk space from removing a media database entry. Leaving index entries of a volume in the media database prevents the accidental labeling of another volume with the same name.
• Recycle volumes that contain recyclable save sets. Changing the volume mode provides details.

  When a volume mode changes to recyclable, the volume becomes eligible for reuse and NetWorker can perform the following operations:

  • Relabel the volume
  • Remove information about the save sets on the volume from the media database
  • Reinitialize the volume

    Once NetWorker relabels a volume, you cannot recover the contents.

    To increase the number of currently recyclable save sets, modify the retention policy that is associated with the current media database by using the nsrmm command. Modifying the browse and retention policy on a save set provides details.

• Compress the media database.Compressing the media database provides details.
