About database updates in configurations with a DAG of Microsoft Exchange servers

In configurations with a DAG of Microsoft Exchange servers, anti-virus database update settings are the same for the entire DAG. This lets you configure centralized updates of anti-virus databases on all servers that are part of the configuration.
Centralized updates for anti-spam and anti-phishing are unavailable for configurations that have a DAG of servers.
You can configure centralized anti-virus database updates in the following ways:
- From Kaspersky update servers. When this method is used, each server in the DAG connects to Kaspersky update servers at the specified time independently of other servers, which causes a great amount of Internet traffic. This method is therefore not recommended for configurations with a large number of servers. Another downside of this method is the need to configure the Internet connection on each server in the configuration. The advantage of this method is high reliability, as updates are performed directly from Kaspersky servers without intermediaries.
- From an intermediate server or network folder. When this method is used, servers belonging to a DAG download updates from an intermediate HTTP server or FTP server or network folder located outside of the configuration of Microsoft Exchange servers. This method reduces the amount of Internet traffic while ensuring fast and synchronized updates on all servers in the configuration, but also entails extra expenses on the upkeep of intermediate hardware.
- From an update center. This method provides for assigning one of the servers in the DAG to act as the update center. The advantages of this method are low Internet traffic, fast and synchronized updates on all servers in the configuration. When this method is used, however, higher reliability requirements apply to the server designated as the update center.
