Bare Metal Restore (BMR) gives you the ability to restore to a virtual server or dissimilar hardware configuration for ease of recovery after a disaster; e.g. hardware failure. This gives you flexibility for restorations and doesn't require the cost and effort of keeping a standby server ready at all times.
MCO’s recovery process is quite simple. When it is time to restore your virtualized server on the NAS device back to physical hardware a boot cd is inserted into the new physical hardware. The new server maps to the NAS device and begins to pull the latest backup image. Once the image is copied to the server MCO manipulates the hardware abstraction layer and inserts the necessary device drivers for the new hardware. Once the server is completely restored backups continue to take place on their scheduled interval.
