Displaying the List of Persistent Images
The Persistent Images page displays all current active persistent images. Each entry identifies the date and time that
the persistent image was created and the volume it preserves. Select an individual persistent image by clicking the radio
button to the left of the description.
1. Log in to the NAS Manager.
See " Logging in to the NAS Manager " in "NAS Manager."
2. Click Disks.
3. Click ActiveArchive.

Adding Persistent Images to the Schedule
1. Log in to the NAS Manager.
See " Logging in to the NAS Manager " in "NAS Manager."
2. Click Disks.
3. Click ActiveArchive.
4. Click Schedules.
5. In the Tasks list on the Persistent Image Schedules page, click New.
6. Use the menus to select the start time (Start at), the frequency at which to repeat the persistent image (Repeat
every), the day to begin (Begin), the volume(s) to include, the image attributes (Read-only or Read/Write),
the retention weight, number of images to save (per schedule), and the persistent image name.
NOTE: To select multiple volumes, press and hold <Ctrl> and select all volumes that are to be included in
the persistent image.
NOTE: If volumes are not protected by RAID 1 or 5 or if volumes are frequently being added and removed,
Dell recommends that you make persistent images of individual volumes. Because multivolume persistent
images are linked to each other, a multivolume persistent image may become inaccessible if one volume in
the multivolume persistent image fails or is removed from the system.
You can use patterns in the persistent image name to differentiate your persistent images. For example if you use a
pattern of Snapshot.%i and you take two persistent images, you have Snapshot.1 and Snapshot.2. The default
persistent image name pattern is Snapshot %M-%D-%Y %H.%m.%s. Valid pattern macros are as follows:
%M = Month
%D = Day
%Y = Year
%h = Hours in 12-hour format
%H = Hours in 24-hour format
%m = Minute
%s = Second
%i = Instance, which increments once per instance
%a = AM/PM
%W = Day of the week
%w = Three-letter day of the week
