Mirror server

The Mirror feature allows a user to create a local update server. Client computers will not download virus signature updates from ESET’s servers on the Internet, but will connect to a local Mirror server on your network instead. The main advantages of this solution are to save Internet bandwidth and to minimize network traffic, since only the mirror server connects to the Internet for updates rather than hundreds of client machines. This configuration means it is important for the Mirror server to always be connected to the internet.

Warning: A Mirror server which performed a program component upgrade (PCU) and has not been rebooted may cause an outage. In this scenario, the server would be unable to download ANY updates or distribute them to client workstations. DO NOT SET AUTOMATIC PROGRAM COMPONENT UPGRADES FOR ESET SERVER PRODUCTS!

The Mirror feature is available in two locations:

ESET Remote Administrator (Mirror physically running within ERAS, manageable from ERAC)

ESET Endpoint Security Business Edition or ESET Endpoint Antivirus Business Edition (provided that the Business Edition has been activated by a license key).

The Mirror is also available in ESET Endpoint Security and ESET Endpoint Antivirus. See documentation for the appropriate client product for more information.

The administrator selects the method for activating the Mirror feature.

In large networks it is possible to create multiple Mirror servers (e.g., for various company departments), and establish one as central (at company headquarters) in cascade-style – similar to an ERAS configuration with multiple clients.

The administrator must insert the product license key for a purchased product and enter the username and password to enable the Mirror feature in the ERAS. If the administrator uses a license key, username and password for ESET Endpoint Antivirus Business Edition, then later upgrades to ESET Endpoint Security Business Edition, the original license key, username and password must be replaced as well.

NOTE: ESET Endpoint Antivirus clients can also be updated using a ESET Endpoint Security license, but not vice versa. This also applies for the ESET Endpoint Antivirus and ESET Endpoint Security.
