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.

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.
