Scheduling Persistent Images
When you click from the NAS Manager primary menu 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 identified by time and date 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.
Displaying the List of Persistent Images
The Persistent Images page displays all currently 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 its check box.

Adding Persistent Images to the Schedule
1. Log in to the 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.
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:
l %M = Month
l %D = Day
l %Y = Year
l %h = Hours in 12-hour format
l %H = Hours in 24-hour format
l %m = Minute
l %s = Second
l %i = Instance, which increments once per instance
l %a = AM/PM
l %W = Day of the week
l %w = Three-letter day of the week
l %% = Percent sign
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 RAID 5, or if volumes are frequently being added and removed, it is recommended 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.
