start time, repetition rate, the volume(s), and so on. For a schedule, you can name
the persistent images based on a pattern you configure. The following format
specifiers allow you to customize variable portions of the name:
%M 3-letter month
%D Day
%Y Year
%h Hour in 12-hour format
%s Second
%i Instance
%a AM/PM
%H Hour in 24-hour format
%W Day of week ( M, T, W ...)
%w 3-letter day of week ( Mon, Tue, Wed ...)
%% Percent sign
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 at the time 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.
Disaster Recovery
PSM provides a disaster recovery solution for the system drive. This extends the
volume restore function of PSM to provide disaster recovery in the event that the
system drive is corrupted to the point where the file system is corrupt, or the
operating system is unbootable. Note that while disaster recovery is also supported
through the Recovery CD-ROM and backup and restore capability, it is a two-step
process. In contrast, the method supported by PSM allows you to restore the
system drive from a single image, without having to go through the entire recovery
procedure and then additionally having to restore a system drive backup.
Use the Disaster Recovery panel to schedule and create backup images of the
system drive, and to create a bootable diskette which will allow you to restore the
system drive from a backup image (located on the maintenance partition, or
network drive). The remainder of this section provides additional information on how
to perform backup and recovery operations for the Model 326.
Note: Restoration of a PSM backup image over the network is not supported for
the Gigabit Ethernet Adapter. If you have only Gigabit Ethernet adapters
installed, it is recommended that you perform PSM backup of each node to
its maintenance partition (D: drive), which would allow you to recover if the
system volume is corrupt and/or unbootable. Should the hard disk drive fail
completely, you would need to use the Recovery CD as described in
“Chapter 9. Using the Recovery and Supplementary CDs” on page 123 to
restore the node to its original (factory) configuration.
Backing up the system drive
The Disaster Recovery panel lists status information for backup operations, both
scheduled and immediate, as well as buttons for starting and stopping a backup
operation, for configuring backup, and for creating a recovery diskette.
