mirroring

   1. <hardware, storage> 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}.
