The master repository is configured when installed. However, you must ensure that proxy server
settings are configured correctly. By default, ePolicy Orchestrator uses Microsoft Internet Explorer
proxy settings.
Distributed repositories
Distributed repositories host copies of your master repository’s contents. Consider using
distributed repositories and placing them throughout your network strategically to ensure
managed systems are updated while network traffic is minimized, especially across slow
connections.
As you update your master repository, ePolicy Orchestrator replicates the contents to the
distributed repositories.
Replication can occur:
• Automatically when specified package types are checked in to the master repository with
global updating.
• On a recurring schedule with Replication tasks.
• Manually, by running a Replicate Now task.
A large organization can have multiple locations with limited bandwidth connections between
them. Distributed repositories help reduce updating traffic across low-bandwidth connections.
If you create a distributed repository in the remote location and configure the systems within
the remote location to update from this distributed repository, the updates are copied across
the slow connection only once — to the distributed repository — instead of once to each system
in the remote location.
If global updating is enabled, distributed repositories update managed systems automatically,
as soon as selected updates and packages are checked into the master repository. You do not
need to spend additional time creating and configuring repositories or the update tasks.
Source site
The source site provides all updates for your master repository. The default source site is the
McAfeeHttp update site, but you can change the source site or create multiple source sites if
you require. McAfee recommends using the McAfeeHttp or McAfeeFtp update sites as your
source site.
NOTE:
Source sites are not required. You can download updates manually and check them in
to your master repository. However, using a source site automates this process.
McAfee posts software updates to these sites regularly. For example, DAT files are posted daily.
Update your master repository with updates as they are available.
Use pull tasks to copy source site contents to the master repository.
The McAfee update sites provide detection definition (DAT) and scanning engine file updates,
as well as some language packs. You must check in all other packages and updates to the
master repository manually.
Fallback site
The fallback site is a source site that’s been enabled as the fallback, from which managed
systems can retrieve updates when their usual repositories are inaccessible. For example, when
network outages or virus outbreaks occur, accessing the established location may be difficult.
Therefore, managed systems can remain up-to-date in such situations. The default fallback site
is the McAfee HTTP (McAfeeHttp) update site. You can enable only one fallback site.
