Describe Mirror Back-ups.

Describe Mirror Back-ups.

Answers

Kavungya
A technique in which data is written to two duplicate disks concurrently to ensure continuous availability. This means installing two disk drives and an equal number of drive controllers such that when the computer writes data on one drive, it automatically writes that data to the other drives and therefore offers synchronized copies on several drives. If one drive fails, the system swaps the failed drive for a new one, ensuring continuity. The problem with mirroring is that if a deletion occurs in one disk, the same will be deleted in the mirror back-up. The disks can be installed on the same machine or over long distance.
