RAID 1
RAID 1 mirrors the contents of the disks, making a form of 1:1 ratio realtime backup. The contents of each disk in the array are identical to that of every other disk in the array. A RAID 1 array requires a minimum of two drives. Although RAID 1's writing process copies the data identically to all drives, a RAID 1 mirror would not be suitable as a permanent backup solution for businesses, since RAID architecture by design allows for certain failures to take place (e.g. vandalism or accidental file deletion). However for home or other applications, where vandalism is very unlikely and accidental file deletion is put up with, RAID 1 offers a good backup solution.
