Veritas NetBackup™ Backup, Archive, and Restore Getting Started Guide

About backup images

NetBackup stores all of the items that are backed up by a single job in a backup image. When you restore files, you select the items to restore from a backup image or from multiple backup images.

Backup images can expire after a certain amount of time (configured by the NetBackup administrator). If a backup image expires, you cannot see or restore its files.
