Pattern File and Engine Updates

It is important to keep your CPM for Mac clients current with the latest pattern and engine files from Trend Micro. The update process can be scheduled to occur automatically and is transparent; there is no need to remove the old pattern or install the new one.

Incremental Updates

To reduce network traffic generated by downloading the latest pattern, the Trend Micro ActiveUpdate server includes incremental pattern updates along with the full pattern file. Updates represent the difference between the previous pattern file and the current one. Like the full pattern file, incremental updates download and apply automatically. Incremental updates are available to both the IBM BigFix Server (which typically downloads pattern updates from the ActiveUpdate server), and to CPM for Mac clients that are configured to get their updates from the BigFix Server.

Updates from the Cloud

Clients typically receive their updates from the BigFix Server or Relays, but CPM for Mac also supports client-updates from the "cloud", that is, directly from the Trend Micro ActiveUpdate server.

Tip: Trend Micro does not recommend updating clients from the cloud as the default behavior.

Pattern files can exceed 20 MB/client, so frequent, direct client downloads from the ActiveUpdate server are not preferred. Instead, you can use the cloud as a fallback for clients to use whenever they are not able to connect to the BigFix Server. Updates from the cloud support incremental pattern updates, but cannot be used to update only certain pattern types.
