browse policy A policy that determines how long entries for backup
data remain in the client file index.
carousel A tray or tape cartridge that holds multiple backup
volumes.
client A computer that accesses the NetWorker server to
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.
