	use. However background copying processes normally continue
	after creation.

source (R1) device	(EMC Symmetrix specific term) An EMC Symmetrix device that
	participates in SRDF operations with a target (R2) device. All
	writes to this device are mirrored to a target (R2) device in a
	remote EMC Symmetrix unit. An R1 device must be assigned to
	an RDF1 group type.
	See also target (R2) device.
source volume	(ZDB specific term) A storage volume containing data to be
	replicated.
sparse file	A file that contains data with portions of empty blocks. Examples
	are: a matrix in which some or much of the data contains zeros,
	files from image applications, and high-speed databases. If
	sparse file processing is not enabled during restore, it might be
	impossible to restore this file.
split mirror	(EMC Symmetrix and HP StorageWorks Disk Array XP specific
	term) A replica created using split mirror techniques. Such a
	replica provides an independent, exact duplicate, or clone of
	the contents of the source volumes.
	See also replica and split mirror creation.
split mirror backup	See ZDB to tape.

specific term)
split mirror backup	See ZDB to tape, ZDB to disk, and ZDB to disk+tape.

split mirror	(EMC Symmetrix and HP StorageWorks Disk Array XP specific
creation	term) A replica creation technique, in which a pre-configured
	set of target volumes (a mirror) is kept synchronized with a set
	of source volumes until the time at which a replica of the contents
	of the source volumes is required. Then, the synchronization is
	stopped (the mirror is split) and a split mirror replica of the
	source volumes at the time of the split remains in the target
	volumes.
	See also split mirror.
