Using Persistent Images
In addition to scheduling persistent images, you can take new persistent images on demand, delete existing persistent
images, configure the persistent image environment, and set persistent image retention weights.
Taking a New Persistent Image on Demand
1. On the NAS Manager primary menu, click Disks, and then click ActiveArchive.
2. Click Persistent Images.
3. In the Tasks list on the Persistent Images page, click New...
4. In the menu that is displayed, select the Volume(s) to preserve.
NOTE: To select multiple volumes, press and hold <Ctrl> and select all volumes that are to be included in
the persistent image.
5. Select the Read Only or Read/Write attribute.
6. Select the Retention Weight for the persistent image.
7. Enter the persistent image name.
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
%s = Second
%i = Instance, which increments once per instance
%a = AM/PM
%W = Day of the week
%w = Three-letter day of the week
%% = Percent sign
8. Click OK to create the persistent image.

2. Click Persistent Images.
