Manual rebuilds are inexpensive as a solution, but recovery time can exceed the maximum tolerable by the business. BMR requires no more infrastructure than do manual rebuilds, but the automation has the potential to greatly reduce the recovery time. Hence, automated bare metal recovery solutions fall under the cost curve, making this solution a cost-effective compromise for data recovery. 2 Why Has This Taken So Long? The principal challenge that all enterprise data protection solutions have faced in performing BMR has been the recovery of the operating system itself.

Check data is information about the user data that is redundant in the sense that it can be used to recover the data if the device that contains it becomes unusable. Array simply refers to the set of devices managed by the control software that presents their net capacity as one or more virtual storage devices. The control software that is typically called a volume manager or logical volume manager runs on the host. In disk systems (commonly called RAID systems), the control software runs in specialized processors within the systems.

Data storage devices are simple devices with straightforward measures of quality. A storage device is perceived as good if it performs well, does not break (is highly available), does not cost much and is easy to manage. Virtualization can be used to improve all four of these basic storage quality metrics: I/O performance. More and more, data access and delivery speed determine the viability of applications. Virtualization can stripe data addresses across several storage devices to increase I/O performance as observed by applications.
