In the context of the NetBackup Vault, a vault is logical entity associated with a particular robot that acts as a designated holding place for backups that eventually are sent to a physical offsite vault. The term "vault" is used to refer both to the process and to the physical storage location of a set of tapes offsite.

Vault is a separately-priced NetBackup option that provides off-site backup management. Vault automates the process of off-site media rotation (a critical component of any backup or disaster recovery strategy). Vault manages off-site storage and retrieval of media for original backups, duplicate backups, and catalog backups. Additionally, NetBackup Vault generates reports to track the location and content of each piece of media.
