Client virus definition revision numbers

I think in SEP by default it keeps three Content revision & deletes the older revisions :)

Hello,

By Default, Symantec Endpoint Protection Manager downloads and keeps 3 Revisions of Virus definition versions in its Repository.

Incase if Space is a Concern in Regards to Virus Definitions Folder Size....

1) Login to Symantec Endpoint Protection Manager

2) Click on Admin

3) Go to Servers

4) Right Click on the Local Site

5) Click on Properties

6) Go to the Liveupdate Tab 

My understanding this setting "Number of content revision to keep" is for SPEM, I need to know the client configuration on the client's machine.

Hello,

Correct,
The above resolution provided is for the SEPM.
However, if we check it properly, the same is reflected to the SEP clients along with Liveupdate downloads and Policies from SEPM at every update..

We cannot control the contents stored by the SEP client atleast from GUI.
SEP caches three defs
called SEP cache1,2 and 3
you can see the usage.dat in virusdefs folder.

usage,dat is indeed has three revision lines of def caches, however, what I observed was that the SEP client only has one version of  def when LiveUpdate successfully download the new def to the machine. or the theory of cach 1, 2, 3 only work when client receives def from managment server, not use Liveupdate?

Hi,

At any session for liveupdate only one revision is downloaded. Be it SEPM or SEP client. SEPM, can store multiple revisions and thats why it can provide multiple revisions.

You can control which revision the clients should have by going into policies->LIveupdate Policy-> LIveupdate Content Policy.

The main purpose behind having multiple policies is to provide a scalable security solution. So, if we see that a particular revision is corrput, we switch to an earlier revision untill a new one is released.

btw, I would like to know how to do this in SAV parent server(SAV10.1), thanks! :)
