252 Glossary
(HP StorageWorks Disk Array XP specific term) The Remote
Control Unit (RCU) acts as a slave of an MCU in a CA
configuration. In bidirectional configurations, the RCU can act
as an MCU.
(Windows specific term) A Windows service used for managing
removable media (such as tapes and disks) and storage devices
(libraries). Removable Storage allows applications to access
and share the same media resources.
(Windows specific term) A system-controlled attribute that can
be associated with any directory or file. The value of a reparse
attribute can have user-controlled data. The format of the data
is understood by the application that stored the data and a
filesystem filter that was installed to interpret the data and
process such files. Whenever the filesystem encounters a file
with a reparse point, it attempts to find the filesystem filter
associated with the data format.
(ZDB specific term) An image, at a particular point in time, of
the data in source volumes that contain user-specified backup
objects. Depending on the hardware or software with which it
is created, the image may be an independent exact duplicate
(clone) of the storage blocks at the physical disk level (for
example, a split mirror or snapclone), or a virtual copy (for
example, a snapshot). From perspective of a basic operating
system, the complete physical disk containing backup objects
is replicated. However, if a volume manager is used on UNIX,
the whole volume or disk group containing a backup object
(logical volume) is replicated. If partitions are used on Windows,
the whole physical volume containing the selected partition is
replicated.

(ZDB specific term) A group of replicas, all created using the
same backup specification.

(ZDB specific term) The use of a replica set for regular backup
production: Each time the same backup specification requiring
the use of a replica set is run, a new replica is created and
added to the set, until the maximum number for the set is
