How the NetWorker server uses volume labels

A volume label is a unique internal code, applied by the NetWorker server, that initializes the volume for the server to use and identifies a storage volume as part of a specific pool. Using media pools provides more information about pools. Labeling a volume provides a unique name for tracking and recognizing the media, as well as references to volume labels in the records stored in the media database. The NetWorker server uses the media database records to determine which volumes are needed for backing up or recovering data.

When NetWorker labels a volume, the label operation performs the following actions:

1. Verifies that the volume is unlabeled.
2. Labels the volume with the name specified in the Volume Name attribute by using one of the following:
   • The next sequential label from the label template that is associated with the chosen pool.

     If a recyclable volume from the same pool is relabeled, the volume label name and sequence number remain the same, but access to the original data on the volume is destroyed. The volume becomes available for new data.

   • An override volume name that was entered by the user.
