1. Writing duplicate data to more than one
device (usually two {hard disks}), in order to protect against
loss of data in the event of device failure. This technique
may be implemented in either hardware (sharing a {disk
controller} and cables) or in software. It is a common
feature of {RAID} systems.

Several {operating systems} support software disk mirroring or
{disk-duplexing}, e.g. {Novell NetWare}.

See also {Redundant Array of Independent Disks}.

Interestingly, when this technique is used with {magnetic
tape} storage systems, it is usually called "twinning".

A less expensive alternative, which only limits the amount of
data loss, is to make regular {backups} from a single disk to
{magnetic tape}.

2. {mirror site}.
