LiveUpdate Administrator 2.x (LUA 2.x) functions as a mirror of internet LiveUpdate content on an enterprise's internal network.  LUA is a fantastic tool when used correctly, but the definitions it downloads and makes available to Symantec Endpoint Protection (SEP) clients will always be larger than the smaller "delta" definitions that a Symantec Endpoint Protection Manager (SEPM) can calculate, create and supply to its managed clients.  (For some more details, please see the article How Big are Current Symantec Endpoint Protection Definitions?)

One potential enhancement to a future release of LUA is to enable it to use the same delta-generating technology that is used in the SEPM.  Clients which come to the LUA server or one of its remote Distribution Centers will receive a file only as large enough as it needs to be, thus making the most efficient use of bandwidth on the corporate network. 

Also: if LUA could use .dax files, it could possible interact better with organizations that currently rely on SEPM and GUPs for client updates (a completely different update architecture).

The downside would be that the LUA server would likely require might more disk space.  Remote DC's would need to be enhanced for increased awareness/interaction, arther than just being a convenient HTTP, FTP or UNC share.

Note: this would not be an easy enhancement, but a major change to the nature of LUA .  Also, it would not benefit any products other than SEP 11 and SEP 12.1.

This could be a huge help for SEP Customers, Germans hate Full Packages as an vdef update...

Adding an additional elaboration for this idea at suggestion of a techie who has worked with LUA for several years.... 

If this idea does ever become a part of LUA 2.x, it would be best to make it optional: LUA will provide its current LU defs, and only if explicitly configured to do will also be able to generate direct deltas.  There should be a checkbox that is un-checked by default, “enable delta creation.”  A note should warn admins up front: “be aware that feature will require an estimated xxx MB additional disk space”.

If both full Internet LU sets are available, plus a whole array of delta files, each set of definitions could consume several GB of hard drive space.

With thanks and best regards,
