There are several types of controls to protect data on the network. My personal favorite is the RAID setup. RAID comes in different variations such as RAID5, RAID1, RAID0, RAID10, and RAID6. The point of the RAID setup is to store copies of data across multiple disks either by pairs or stripes or both in the cases of RAID5 and 6. In the event of a disk becoming corrupt or crashes, the data that has been copied to another disk can be used to rebuild the crashed disk. This is a good method of data loss prevention. Another method is the iSCSI protocol. it has the benefit of appearing to be a local network but actually provides remote access.
