ACCUDUAL
RAID level 1 concept (Disk mirroring)
RAID is an acronym of Redundant Array of Independent/Inexpensive Disks.RAID1 is
one of several RAID levels. RAID 1 also known as "Disk mirroring". Data are written
to both disks simultaneously. RAID1 provides both high reliability and continued
data availability in the event of failure of an array member. When a RAID1 member
disk fails, array management simply directs all application requests to the
remaining disk. RAID1 is suitable for data which reliability requirements are
extremely high, or for data to which high performance access is required.
Disk backup function description
