of another program, called the server. The following
types of clients can obtain services from an IBM Tivoli
Storage Manager server: administrative client,
application client, API client, backup-archive client, and
HSM client (also known as space manager client).
client node. A file server or workstation on which the
backup-archive client program has been installed, and
which has been registered to the server.
client options file. A file that a client can change,
containing a set of processing options that identify the
server, communication method, and options for backup,
archive, hierarchical storage management, and
scheduling. Also referred to as the dsm.opt file.
copy group. A policy object whose attributes control
how backup versions or archive copies are generated,
where backup versions or archive copies are initially
located, and when backup versions or archive copies
expire. A copy group belongs to a management class.
D
data manager server. A Tivoli Storage Manager server
that collects metadata information for client inventory
and manages transactions for the storage agent over the
LAN. The data manager server informs the storage
agent with applicable library attributes and the target
volume identifier.
