About the recovery disk image process
You can create a disk image of the K2 Media Client system drive and restore from the
image. This simplifies the process of rebuilding a system in a disaster-recovery
scenario.
NOTE: This process is not intended as a means to backup and restore media.
You can also create a disk image of the Control Point PC system drive and restore
from the image.
The system drive of the K2 Media Client is actually a logical drive made up of a RAID
1 pair of disks. The system drive is divided into three partitions, as follows:
• The C: partition — This is the normal PC system drive, which hosts the Windows
operating system and most software components.
• The D: partition — This drive contains the media file system software, including
the media file system metadata files and journal files. The drive also contains the
media database application (SQL) and data files. By storing the media file system
metadata and the media database —both of which contain references to the media
files—on a separate drive, you can re-image the C: system drive while saving your
media.
• The E: partition — This is where recovery disk images are stored.
When you receive your K2 Media Client new from the factory, a default disk image
is stored on the E: partition. This image is generic for all K2 Media Clients, regardless
of the storage type.
You receive a recovery CD with your K2 Media Client. This recovery CD does not
contain a disk image. Rather, the recovery CD is bootable and contains the Acronis
True Image software necessary to create and restore a disk image. You can use the
recovery CD to create and restore disk images for the K2 Media Client and for the
control point PC. Refer to K2 Media Client Release Notes for compatible versions of
the recovery CD.
After your K2 Media Client is installed, configured, and running in your system
environment, you should create new recovery disk images to capture settings changed
from default. These “first birthday” images are the baseline recovery image for the K2
Media Client in its life in your facility. You should likewise create a new recovery
disk image after completing any process that changes system software or data, such
as a software upgrade. In this way you retain the ability to restore your K2 Media
Client to a recent “last known good” state.
For the highest degree of safety, you should create a set of disk image recovery CDs,
in addition to storing disk images on the E: partition. Since the system drive is RAID
protected, in most cases the disk images on the E: partition will be accessible. But in
the unlikely even of a catastrophic failure whereby you lose the entire system drive
RAID 1 LUN, you can use your disk image recovery CDs to restore the system. You
should also create a set of disk image recovery CDs for the Control Point PC.
NOTE: The recovery disk image process is an “off-line” process. Do not attempt
this process while media access is underway.
