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.
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 -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.

split mirror restore (EMC Symmetrix
and HP StorageWorks Disk Array XP
specific term)
A process in which data backed up in a
ZDB-to-tape or a ZDB-to-disk+tape
session is restored from tape media to a
split mirror replica, which is then
synchronized to the source volumes.
Individual backup objects or complete
sessions can be restored using this
method.

disk+tape, and replica.
