Schedules

Use this panel to schedule persistent images to be taken at specific times (this is
independent of the scheduled backup function through NAS Backup Assistant
described earlier). Each PSM schedule entry defines a set of persistent images to
be taken starting at a specified time and at a specified interval, with each image
having the set of properties defined in the entry. This allows you to customize
scheduled persistent images on a per-volume basis. For instance, you could set a
persistent image for one volume to occur every hour, and for another volume to
occur only once a day.
The set of properties you define are the same properties described in the Persistent
Images panel description assigned above; when you define these properties, all
persistent images created according to this schedule entry will be given those
properties. After a scheduled persistent image is created, certain properties of that
persistent image can be modified through the Persistent Images panel,
independently of other persistent images created according to the schedule.
After you create a schedule entry, it appears in the list of scheduled persistent
images. Subsequently, you can modify the properties of an existing entry, such as
start time, repetition rate, the volumes, and so on. For a schedule, you can name
the persistent images based on a pattern that you configure. The following format
specifiers allow you to customize variable portions of the name:
%M
%D
%Y
%h
%s
%i
%a
%H
%W
%w
%%
As an example, the name pattern %w_%M_%D_%Y_%h_%m_%a would produce
the persistent image name Mon_Apr_1_2002_10_47_AM.

Restore Persistent Images

On this panel, you can select an existing persistent image and quickly restore the
volume contained in the image back to the state it was in when the selected
persistent image was taken. This is useful if you need to recover an entire volume,
as opposed to just a few files. This volume restore function is available for the data
volumes, but not the system volume.
