Storing Persistent Images
You can store up to 250 persistent images per volume; however, if you exceed 250 persistent
images, the oldest persistent image with the lowest retention weight is overwritten. This
number of persistent images allows you to schedule multiple persistent images. For
example, you could implement a typical schedule similar to the following schedule. (You
should tailor your schedule depending on how the data is changing.)
• Seven daily persistent images
• Two weekly persistent images
• Two monthly persistent images
Accessing Directories, Folders, and Files
By default, administrators can access the ActiveArchive directory in the root of each
volume. Each persistent image is displayed separately with a date and time stamp show ing
when the persistent image occurred. The administrator can browse the persistent image as
if it were a standard volume. To access the ActiveArchive directory from the NAS Manager
home page, click Disks and then click ActiveArchive. Each persistent image is mounted as a
volume on the file system to allow access by clients. Persistent images are created as
read-only.
Persistent image directories are used in the same way that conventional directories are used.
The files and folders in the persistent image directories have the same permissions as the
files and folders on the original volume. All persistent images are persistent and will survive
system power losses or reboots.
NOTE: The ActiveArchive directory is a hidden folder. You must configure your system to view
hidden files and folders to view your ActiveArchive directory.
Allowing User’s Access to Persistent Images
To allow user’s to access the persistent images, the system administrator must modify the
permissions for the ActiveArchive directory. The files and folders within a persistent image
are identical to the permissions on the original files and folders. Use the PowerVault NAS
Manager to change the ActiveArchive directory permissions by performing the following
steps.
