Data security is one of the most important issues in the use of computers. Generally, Hard Disk Mirroring technology is used in the server environment to achieve dual data backup. We can also use this technology in Linux.
In Linux, Raidtools can be used to mirror not only two hard disks, but also soft RAID 0, RAID 1, and RAID 5. It is soft
