Media

Media, or media volume, is a storage unit such as tape or Disk Directory

Media volumes are physical media, such as tape cartridges, or logical storage units, such as Disk Directories, to which data can be backed up or duplicated. Data can only be backed up or duplicated to volumes that have been defined.

A media volume has a unique volume name (also abbreviated to volser = volume serial number) and must be a member of a media pool. You can define media pools and their member media volumes, as well as modify and delete those definitions.

When creating a node group, specify, from the media pools you have created, a default media pool for the node group. Later, when you define a backup or migrate job, you can override this default. During a backup, DPX issues prompts to the media operator or media changer to mount media volumes from the default or specified media pool. The specific volume is chosen from the media pool by DPX and cannot be predicted.

Note. Media pools are also called tape pools. Media volumes are also called tapes or media.
