Replication tasks
Use replication tasks to copy the contents of the master repository to distributed repositories.
Unless you have replicated master repository contents to all your distributed repositories, some
systems do not receive them. Ensure all your distributed repositories are up-to-date.
NOTE:
If you are using global updating for all of your updates, replication tasks may not be
necessary for your environment, although they are recommended for redundancy. However, if
you are not using global updating for any of your updates, you must schedule a Repository
Replication server task or run a Replicate Now task.
Scheduling regular Repository Replication server tasks is the best way to ensure that your
distributed repositories are up-to-date. Scheduling daily replication tasks ensures that managed
systems stay up-to-date. Using Repository Replication tasks automates replication to your
distributed repositories.
Occasionally, you may check in files to your master repository that you want to replicate to
distributed repositories immediately, rather than wait for the next scheduled replication. Run a
Replicate Now task to update your distributed repositories manually.
Full vs. incremental replication
When creating a replication task, select Incremental replication or Full replication.
Incremental replication uses less bandwidth and copies only the new updates in the master
repository that are not yet in the distributed repository. Full replication copies the entire contents
of the master repository.
TIP:
McAfee recommends scheduling a daily incremental replication task. Schedule a weekly
full replication task if it is possible for files to be deleted from the distributed repository outside
of ePolicy Orchestrator's own replication functionality.
Repository selection
New distributed repositories are added to the repository list file containing all available distributed
repositories. The agent of a managed system updates this file each time it communicates with
the ePO server. The agent performs repository selection each time the agent (McAfee
Framework Service) service starts and when the repository list changes.
Selective replication provides more control over the updating of individual repositories. When
scheduling replication tasks, you can choose:
• Specific distributed repositories to which the task applies. Replicating to different distributed
repositories at different times lessens the impact on bandwidth resources. These repositories
can be specified when you create or edit the replication task.
• Specific files and signatures that are replicated to the distributed repositories. Selecting only
those types of files that are necessary to each system that checks into the distributed
repository lessens the impact on bandwidth resources. When you define or edit your
distributed repositories, you can choose which packages you want to replicate to the
distributed repository.
NOTE:
This functionality is intended for updating products that are installed only on several
systems in your environment, like GroupShield and WebShield. The functionality allows you to
distribute these updates only to the distributed repositories these systems use.
