Grass Valley K2 (Summit 3G) 10Gv2 Storage Area Network Installation v.8.1 - Manual (Page 117)

After your server is installed, configured, and running in your system environment, you should
create new recovery disk images for the machine to capture settings changed from default. These
“first birthday” images are the baseline recovery image for the machine in its life in your facility.
You should likewise create new recovery disk images after completing any process that changes
system software or data, such as a software upgrade. In this way you retain the ability to restore 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 system drives are RAID protected, in most failure
cases the disk images on the E: partition will still be accessible. But in the unlikely even of a
catastrophic failure whereby you lose the entire RAID protected system drive, you can use your
disk image recovery CDs to restore the system.
NOTE: Recovery disk images do not back up the media files themselves. You must implement
other mechanisms, such as a redundant storage system or mirrored storage systems, to back up
media files.
Recommended recovery process
The recommended recovery disk image process is summarized in the following steps.
At the K2 Media Server first birthday...
1. Boot from the Recovery CD.
2. Create a set of disk image recovery CDs. These CDs contain the C:, D:, and E: partitions.
3. Create a disk image, writing the disk image to the E: partition. This disk image contains the C: and D:
partitions.
4. Copy the disk image from the E: partition to another location, such as a network drive.
At milestones, such as after software upgrades…
1. Boot from the Recovery CD.
2. Create a disk image, writing the disk image to the E: partition. This disk image contains the C: and D:
partitions.
3. Copy the disk image from the E: partition to another location, such as a network drive.
If you need to restore the K2 Media Server…
1. Boot from the Recovery CD.
2. If the E: partition is accessible, read the image from the E: partition to restore the C: partition, restore the
D: partition, or restore both partitions.
3. If the E: partition is not accessible, do the following:
a. Read the disk image from your set of CDs and restore all three partitions
b. Restart into Windows.
c. Copy your most recent disk image to the E: partition.
d. Boot from the Recovery CD.
e. Read the image from the E: partition to restore the C: partition, restore the D: partition, or restore both
partitions.
Plan a recovery strategy that is appropriate for your facility, then refer to procedures as necessary
to implement your strategy.
