GUP providing full update

Created: 21 Feb 2013 | 10 comments

If 1 client (LiveUpdate Policy with GUP) has a definition too old (not stored on the SEP Manager), the GUP cannot provide delta.
So, in this case, GUP downloads full update from SEPM and then client download full update from GUP.

If a second client, short after, has the same situation, what happens?
Will the GUP provide directly the same full update it downloaded before for the other clients or the GUP has to download full package for every single clients that need it?

Hello,

Check these Articles:

When does a client download full.zip from SEPM/GUP?

http://www.symantec.com/business/support/index?pag...

Symantec Endpoint Protection clients download full definitions from Group Update Provider or from Symantec Endpoint Protection Manager

Hope that helps!!

Uhm... this did not help...

I know when I client needs a full update.

What I don't know if: if 2 clients (referred to the same GUP) must download full package, will GUP download full package 2 times from SEPM or it downloads it only first time then it mantains it and give it to the second?

See my note below:

 

- will GUP download full package 2 times from SEPM - no

- or it downloads it only first time then it mantains it and give it to the second? - yes

 

Hope that helps.

A: The second client will be provided with the same full update - at the time the client requests the full .zip GUP first checks if that file is available locally on GUP (sharedUpdates folder) -if it is, the client will get the cached file, no need again to go to SEPM.

Ok. This helps surprise

Another question. Is it GUP able to use its own definition (the one used by itself) to provide it to the same (32 or 64bit) system?

Don't think so because a normal client does not have zip stored on the hard drive but... just to be sure :-)

No. GUP uses the SharedUpdates folder to send the files to the other clients.

The Local SEP client uses the the Definitions folder instead.

C:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\12.1.2015.2015.105\Data\Definitions

Treat the GUP and the SEP client on the GUP separately - the SEP client needs to request the defs - so it behaves as any other client on any other machine. It won't use directly the defs stored in GUP cache folder - so it will request the update from GUP - GUP will check if delta is in cache, if not it will provide the full.zip

GUP will Download the Full Data if the SEPM is unable to build the Delta for the Content because Client donot make own Delta, it is dependent on SEPM.

One thing you need to look here at as well is the setting in the LU policy for the - maximum disk cache size allowed for downloading updates in MB on GUP - as the full.zip packages are quite big - it may happen that before the second client requests the same full.zip that was already requested before - GUP in the meantime may already purge its cache - this way this file will not be available anymore = GUP will then need to download it again.
