back up or recover files. Clients may be workstations,
computers, or fileservers.
client file index
A database of information maintained by the
NetWorker server that tracks every database object,
file, or
filesystem backed up. The NetWorker server
maintains a single client index file for each client
computer.
client-initiated
backup See manual backup .
clone The NetWorker process used to make an exact copy of
saved data (save sets). You can clone individual save
sets or the entire contents of a backup volume.
Cloning is different from a simple copy operation
carried out on an operating system or hardware
device. It is indexed and tracked by NetWorker
software in both the
client file index and the media
database .
clone pool
A pool of volumes composed exclusively of cloned
data. Three types of clone pools can be used: backup
clone, archive clone, and migration clone. Save sets of
different types (for example, archive and migration)
cannot be intermixed on the same clone volume.
clone volume A volume belonging to a clone pool.
cluster
Two or more nodes that are connected and appear to
network users as a single, highly available system. A
highly available system allows the application
services to continue despite most hardware or
software failures.
connection port The port NetWorker processes use to perform backup
and recovery sessions through a firewall.
