Sophos updating policy secondary server
We recommend that you always specify a secondary source.Both primary and secondary update server locations may be either UNC shares or HTTP URLs from any accessible Update Manager on your network.
You should allow location roaming on an updating policy for laptop users who roam extensively or internationally within an organization.When this option is enabled, roaming laptops will attempt to locate and update from the nearest location by querying fixed endpoints on the same local network they are connected to, which minimizes update delays and bandwidth costs.If multiple locations are returned, the laptop determines which is nearest and uses that location. You can also specify an alternative secondary source for updates, enable location roaming, and enable bandwidth throttling.If endpoint computers cannot contact their primary source, they attempt to update from their secondary source (if one has been specified).Ensure that the number of groups using the same updating policy is manageable.
You should normally have no more than 1,000 computers updating from the same location.
However, we recommend that you also always set up an alternative secondary location for updates.
If endpoint computers cannot contact their primary location, they will attempt to update from their secondary location if set.
The optimum number updating from the same location is Note: The number of computers that can update from the same directory depends on the server holding that directory and on the network connectivity.
By default, computers update from a single primary location.
Any third-party firewalls must be configured to allow update location queries and responses.
