Update Agent Component Duplication<br />

Like the <strong>OfficeScan</strong> server, Update Agents also use component duplication when<br />

downloading components. See <strong>OfficeScan</strong> Server Component Duplication on page 5-17 for<br />

details on how the server performs component duplication.<br />

The component duplication process for Update Agents is as follows:<br />

1. The Update Agent compares its current full pattern version with the latest version<br />

on the update source. If the difference between the two versions is 14 or less, the<br />

Update Agent downloads the incremental pattern that accounts for the difference<br />

between the two versions.<br />

Note: If the difference is more than 14, the Update Agent automatically downloads the<br />

full version of the pattern file.<br />

2. The Update Agent merges the incremental pattern it downloaded with its current<br />

full pattern to generate the latest full pattern.<br />

3. The Update Agent downloads all the remaining incremental patterns on the update<br />

source.<br />

4. The latest full pattern and all the incremental patterns are made available to clients.
