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.

mirror creation.
replica set (ZDB specific term) A group of replicas, all created using the
same backup specification.
See also replica and replica set rotation.
replica set rotation (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
reached. After that, the oldest replica in the set is replaced,
maintaining the maximum number of replicas in the set.
See also replica and replica set.
restore chain All backups that are necessary for a restore of a backup object
to a certain point in time. A restore chain consists of a full
backup of the object and any number of related incremental
backups.
restore session A process that copies data from backup media to a client.
resync mode (HP StorageWorks Disk Array XP VSS provider specific term)
One of two XP VSS hardware provider operation modes. When
the XP provider is in the resync mode, the source volume (P-VOL)
and its replica (S-VOL) are in the suspended mirror relationship
after a backup. The maximum number of replicas (S-VOLs per
a P-VOL) rotated is three provided that MU range is 0-2 or 0,
1, 2. Restore from a backup in such a configuration is possible
only by re-synchronization of an S-VOL with its P-VOL.
See also VSS compliant mode, source volume, primary volume
(P-VOL), replica, secondary volume (S-VOL), MU number, and
replica set rotation.
RMAN
(Oracle
specific term)
See Recovery Manager.
RSM The Data Protector Restore Session Manager controls the restore
session. This process always runs on the Cell Manager system.
