Use the Components tab to select which components to update.
To select components to download:
-
From the schedule update rule or manual update document, click the Components tab to set which components to download (see Automatically) or (Manually).
-
Under the Update Components group, select the components to download.
-
Under the Options group, type values in the Retain pattern file history ["x" pattern files] and Retain scan engine history ["x" scan engines] fields to indicate the number of files ScanMail will save.
Note
Because pattern files and scan engine can take up disk space, Trend Micro recommends keeping three (3) previous pattern file and two (2) previous scan engine versions on hand (in addition to the current version). As subsequent pattern file or scan engine updates occur, the oldest component is deleted for each new one added. -
Under Component update, select how ScanMail applies the program update: Download only or Download and apply.
Tip
Use care when applying these options alternately. If you use the Download only option, and then run an update, the latest component will be downloaded to the Update Database. If you then decided to change the setting to Download and apply, ScanMail will not download any components because the ones in the Update Database are already the latest. This prevents ScanMail from applying the latest components to the servers in the Apply To General setting. In this case, use Replicated database as the Update Source to download and apply the latest components to other servers. -
Select the appropriate options from Download components for platforms.
