Definicja disk mirroring
A means of protection against disk failures by using redundant disks.
Disk mirroring means writing or mirroring identical data to physically different disk locations to guard against disk failures. Mirroring can be driven by hardware (disk controller, RAID disks using RAID 1) or software (CPU code to emulate mirroring, known as LVM). The mirrored data can reside on either another disk spindle within the same disk array (RAID 1) or a standalone disk (LVM).
