How Client Agents Work

BrightStor ARCserve Backup and the client agents are designed to support

data storage activities for companies and organizations with networked

computers. In these scenarios, Computer Associates customers use the

BrightStor ARCserve Backup base product and its client agents (and any

required options). The client agents allow you to back up and restore mission-

critical data on your network. They help to:

Facilitate backup of applications or file systems

Facilitate monitoring of the backup progress

Facilitate monitoring for backup log activities

With client agents installed on your network computers, a single BrightStor

ARCserve Backup server can perform data backup and restore operations on

multiple computers and operating systems.

Agent Features

This section discusses the features and functionality offered by the various

BrightStor ARCserve Backup client agents.

Push Technology

All client agents use push technology, which automates the backup and restore

process. The client agent contains separate internal client engines that help

reduce the resource-intensive backup processes for the BrightStor ARCserve

Backup server. With this feature, the client agent filters and packages its

archive data for reception by the server. This data preparation and

transmission method provides real-time directory browsing, offloading system

resources from the backup server, improves data transfer through use of

packet technology, provides network security, and monitors backup and

restore jobs.
