HP Application Recovery Manager software A.06.10 Concepts guide (March 2008)

used in operating systems as a means of specifying more than
one file by name.
Windows Registry A centralized database used by Windows to store configuration
information for the operating system and the installed
applications.
WINS server A system running Windows Internet Name Service software that
resolves Windows networking computer names to IP addresses.
writer (Microsoft VSS specific term) A process that initiates change of
data on the original volume. Writers are typically applications
or system services that write persistent information on a volume.
Writers also participate in the shadow copy synchronization
process by assuring data consistency.
ZDB See zero downtime backup (ZDB).
ZDB database (ZDB specific term) A part of the IDB, storing ZDB related
information such as source volumes, replicas and security
information. The ZDB database is used for ZDB and instant
recovery.
See also zero downtime backup (ZDB).
ZDB to disk (ZDB specific term) A form of zero downtime backup where the
replica produced is kept on the disk array as a backup of the
source volumes at a specific point in time. Multiple replicas,
produced using the same backup specification at different times,
can be kept in a replica set. A replica from ZDB to disk can be
restored using the instant recovery process.
See also zero downtime backup (ZDB), instant recovery, and
replica set rotation.
zero downtime
backup (ZDB)
A backup approach in which data replication techniques,
provided by a disk array, are used to minimize the impact of
backup operations on an application system. A replica of the
data to be backed up is created first. All subsequent backup
operations are performed on the replicated data rather than the
original data, while the application system can be returned to
normal operation.
See also ZDB to disk and instant recovery.
