Symantec LiveUpdate, which provides updates, upgrades, and new versions of Backup Exec, is installed automatically with Backup Exec. If you enable the automatic update option, you can configure LiveUpdate to poll the main Symantec Web server on a scheduled interval. The automatic update option only searches for Backup Exec updates. It does not show updates for other Symantec products that use LiveUpdate. Likewise, when LiveUpdate is scheduled to automatically update other Symantec products, it does not search for Backup Exec updates.
In addition to scheduling LiveUpdate, you can also run it manually at any time. You can access LiveUpdate from several locations in Backup Exec. However, you cannot access it from the Windows Start menu.
When LiveUpdate installs updates on the Backup Exec media server, it also determines if computers on which the Remote Agent for Windows Systems have the latest updates. If you do not have the latest updates you receive an alert to install the updates. You can push-install or manually copy those updates to Backup Exec Remote Agents.
You can use the LiveUpdate Administrator Utility with LiveUpdate. The LiveUpdate Administrator Utility allows an administrator to modify LiveUpdate so that network users can download program and virus definition updates from an internal server rather than going to the Symantec LiveUpdate server over the Internet.
