Question

He should implement RAID 1 or data mirroring to be able to replace a failed hard drive on the fly.
Key Takeaway: RAID 1 creates an exact copy (or mirror) of a set of data on two or more disks. This is useful when read-performance or reliability is more important than data storage capacity. A drive has its data duplicated on two different drives using either a hardware RAID controller or software. If either of the drives fail, the other continues to function as a single drive until the failed drive is replaced. It is popular for those who require fault tolerance and don't need top-notch read performance.
