Sgromolo engages in data mirroring

Explanation:

The end goal of data mirroring is to increase data protection by providing shields to a computer system thereby preventing it from data loss and other possible losses due to data failures.

The technique used in data mirroring is that, it uses realtime protection of data by taking a data and replicating the exact copy without adding to or removing from it, to another storage location.

In this technique, Sgromolo picks up these data people think are n longer usable, and duplicated by being written to two or more identical hard drives, all of which are connected to one disk controller card.
