Dell NetWorker 19.9 Administration Guide

Labeling volumes

The NetWorker software applies a label template to create a unique internal label for each volume. The label corresponds to a pool and identifies the pool for the volume during backup and other operations.

Several preconfigured label templates are supplied with the NetWorker software. You cannot delete these preconfigured label templates. Naming label templates provides more information.

When you label a volume, the labeling process:

• Writes a label on the volume.
• Adds the volume label to the media database.
• Prepares tape media to have data written to it.

When you re-label tape, the data on the tape is effectively gone.

During data recovery, the server requests the volume that contains the required data, identifying the required volume by the name with which it was labeled.
