(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.

(ZDB specific term) A storage volume containing data to be
replicated.
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.
(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.

(EMC Symmetrix and HP StorageWorks Disk Array XP specific
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.
