Glossary
resource A component of the NetWorker software that
describes the NetWorker server and its clients.
Devices, schedules, clients, groups, and policies are
examples of NetWorker resources. Each resource
contains a list of attributes that define the parameters
to use for the specific NetWorker resource.
resource database A database that contains information about each of the
configured backup server’s resources.
resource owner The cluster (logical, not physical) host that owns the
resource. If a resource (for example, a shared disk) is
not owned by any virtual host, it is assumed to be
owned by the local host (physical node) that hosts the
resource.
retention policy A policy that determines how long save set entries are
retained in the NetWorker server’s media database.
retrieve The process of locating and copying back files and
directories that NetWorker software has archived.
retry mechanism The action NetWorker software performs when client
operations fail. This situation might occur when the
rate of transmission is either low or nonexistent. By
using this mechanism, a previously failed operation
might be more successful. Another common situation
whereby a retry mechanism might succeed is when
the client is in a reboot cycle.
root 1. (UNIX only) The UNIX superuser account (with
user name “root” and user ID). By extension, the
privileged system-maintenance login on any
operating system.
2. (Windows NT/Windows 2000 and UNIX) The top
node of the system directory structure; the home
directory of the root user.
save set A group of files or a filesystem from a single client
computer backed up onto storage media.
