Update rollback

If you suspect that a new detection engine update or program modules may be unstable or corrupt, you can roll back to the previous version and temporarily disable updates. Alternatively, you can enable previously disabled updates if you had postponed them indefinitely.

ESET Mail Security records snapshots of the detection engine and program modules for use with the rollback feature. To create virus database snapshots, keep Create snapshots of modules enabled.

When Create snapshots of modules enabled, the first snapshot is created during the first update. The next one is created after 48 hours.

The Number of locally stored snapshots field defines the number of stored detection engine snapshots.


When the maximum number of snapshots is reached (for example, three), the oldest snapshot is replaced with a new snapshot every 48 hours. ESET Mail Security rolls back detection engine and program module update versions to the oldest snapshot.

Click Rollback, you have to select a time interval from the drop-down menu that represents the period of time that the detection engine database and program module updates will be paused.


Select Until revoked to postpone regular updates indefinitely until you restore update functionality manually. Since it represents a potential security risk, we recommend not selecting this option.

If a rollback is performed, the Rollback button changes to Allow updates. Updates are not allowed for the time interval selected from the Suspend updates drop-down menu.

The detection engine database version is downgraded to the oldest available and stored as a snapshot in the local computer file system.
