About the recovery disk image process
You can create a disk image of the K2 Dyno S Replay Controller 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.
When you receive your K2 Dyno S Replay Controller new from the factory, you a receive
a system-specific disk image for that particular K2 Dyno S Replay Controller. This factory
image is stored on a bootable USB Recovery Flash Drive. Also on the Recovery Flash
Drive is the Acronis True Image software necessary to create and restore a disk image.
After your K2 Dyno S Replay Controller 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 Dyno S Replay Controller in its life in your facility. There is enough disk space on the
Recovery Flash Drive to store the first birthday image along with the factory image.
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 Dyno S Replay Controller to a recent “last known good” state.
