Update Agent Component Duplication
Like the OfficeScan server, Update Agents also use component duplication when
downloading components. See Server Component Duplication on page 4-16 for details on
how the server performs component duplication.
The component duplication process for Update Agents is as follows:
1. The Update Agent compares its current full pattern version with the latest version
on the update source. If the difference between the two versions is 14 or less, the
Update Agent downloads the incremental pattern that accounts for the difference
between the two versions.
Note: If the difference is more than 14, the Update Agent automatically downloads the
full version of the pattern file.
2. The Update Agent merges the incremental pattern it downloaded with its current
full pattern to generate the latest full pattern.
3. The Update Agent downloads all the remaining incremental patterns on the update
source.
4. The latest full pattern and all the incremental patterns are made available to clients.
Update Methods for Update Agents
Update Agents use the same update methods available to regular clients. For details, see
Client Update Methods on page 4-27.
You can also use the Scheduled Update Configuration tool to enable and configure
scheduled updates on an Update Agent that was installed using Client Packager.
Note: This tool is not available if the Update Agent was installed using other installation
methods. See Installation Methods on page 3-18 for more information.
