Configure update servers

By default, computers update from a single primary source UNC share, \\<ComputerName>\SophosUpdate, where <ComputerName> is the name of the Update Manager’s computer. 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). 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. The secondary update server location may alternatively be set to get updates directly from Sophos over the internet via HTTP.
Note: Update Managers may have multiple distribution shares available, depending on how you have set them up.
