I appreciate the pointer above in regards to mirror usage. I'd be creating this local mirror to remove some load from the other mirrors as we provision anywhere between 1-25 CentOS based servers per week. In this case, what mirror would I use for syncing these repos?

Also, is it possible to create a repo in a sort of 'cache' mode where packages are only stored on the local repo if requested by a device using the repo? Essentially a 'yum caching proxy' for lack of a better term?
