Recovery Manager
(RMAN)

(Oracle specific term) An Oracle command-line interface that
directs an Oracle Server process to back up, restore, or recover
the database it is connected to. RMAN uses either the recovery
catalog or the control file to store information about backups.
This information can be used later in restore sessions.

recycle

A process that removes the data protection from all backed up
data on a medium, allowing Data Protector to overwrite it during
one of the next backups. Data that belongs to the same session(s)
but resides on other media is also unprotected. Recycling does
not actually alter the data on the medium.

redo log

(Oracle specific term) Every Oracle database has a set of two
or more redo log files. The set of redo log files for the database
is known as the database's redo log. Oracle uses the redo log
to record all changes made to data.

Remote Control
Unit (RCU)

(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.

Removable
Storage

(Windows specific term) A Windows service used for managing
removable media (such as tapes and disks) and storage devices

Management
Database

(libraries). Removable Storage allows applications to access
and share the same media resources.

reparse point

(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.

replica

(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
