Scheduling Persistent Images
When you click Disks® ActiveArchive® Schedules, the Scheduled Persistent Image page displays a list of all
scheduled persistent images and associated tasks. Each scheduled persistent image is identified by the scheduled time,
day, frequency, starting date, and target volume ID. Persistent images are identified by time and date and are located in
the ActiveArchive directory. The ActiveArchive directory is located in the root of each ActiveArchive volume. Only the
administrator can access the ActiveArchive directory. The files and folders in the persistent image directories have the
same permissions as the files and folders on the original volume. Persistent image directories are used exactly the same
way as conventional system volumes. Unlike conventional volumes, read-only persistent image images are static,
recording the precise content of the originating volume at the time you created the persistent image.
