Until now, the full recovery of a server after a catastrophic failure could take several hours. Bare Metal Recovery technology is able to quickly recover an unusable system. It can restore both system and data in a single pass, eliminating the need for multiple backups and significantly reducing downtimes.

Bare-metal restore is a technique where the backed up data is available in a form which allows one to restore a computer system from “bare metal”, i.e. without any requirements as to previously installed software or operating system. Typically, the backed up data include the necessary operating system, applications and data components to rebuild or restore the backed up system to an entirely separate piece of hardware. Bare-metal restore differs from simple data backups where application data, but neither the applications nor the operating system are backed up or restored as a unit. It also differs from the local disk image restore. The local disk image restores from a copy of the disk image and the software performing the restore is invoked by booting the server with the setup/installation disk. Such server backup application supplied with the OS is not designed to be an enterprise-level solution. Bare metal restore for rebuilding a server from ground up is offered by many disaster recovery solution providers.

Vendors offer an optional “bare metal” restoration for rebuilding a computer or server from scratch. Using a separate storage device, the vendor creates a mirror image of the client’s complete system. The device is then shipped to the data center and stored. In case of a system crash, the system can be restored to its original configuration.

The virtual machine technology enables multiple operating systems to run concurrently on a single machine. Virtualization increases the efficiency and the effectiveness of the disaster recovery process and offers cost-savings opportunities. Virtualization is hardware-agnostic; systems can be restored without identical or near-identical hardware. This creates flexibility and expands options regarding the type of hardware one can recover to in case of hardware failure. The virtual server software creates a generic hardware platform that’s consistent, regardless of the physical hardware used to host the virtual servers. This simplifies the “bare metal” restore process, because it is possible to perform a bare metal install on dissimilar hardware.

Outsourcing the disaster recovery solution to a vendor that specializes in
Virtual machine technology along with integrated bare metal restore is the best possible DR solution for an enterprise dealing in mission-critical data.
