By default, the Update type is set to Regular update. This ensures the detection signature database and product modules are updated automatically on a daily bases directly from ESET update servers.

Pre-release updates include most recent bug fixes and/or detection methods that will be available to the general public soon. However, they might not be stable at all times, therefore it is not recommended to use them in a production environment.

Delayed updates allow updating from special update servers providing new versions of virus databases with a delay of at least X hours (that is, databases tested in a real environment and considered stable).

If an ESET File Security for Linux update was not stable, roll back the module updates to a previous state. Click Dashboard > Modules update > Module rollback, select the desired duration, click Rollback now.

You can define up to two alternative update sources, a primary and secondary server.
