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.

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.

split mirror
creation (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.
