Special considerations must be taken when restoring to a new disk. You must be aware of how the new drive differs from the original. For instance, is the new disk larger or the same size as the old one? Is the new disk SCSI and the original was IDE? When should you restore the Master Boot Record (MBR)? The MBR is the first part of the drive that contains the partition layout and data used to boot the server. These considerations are discussed in the next section.
Note: A bare metal backup cannot be restored to a smaller disk.
