Does Stash support any kind of mirroring capabilities?

Currently the Stash team is working on a solution that will allow users to mirror their production instance on another instance of Stash. This will be useful for teams who've been hitting Stash with a high amount of continuous integration requests, i.e. your CI server, like Jenkins or Bamboo, clone your repositories every time a change is pushed into the repo. By shifting this CI cloning to the mirror instance, you'll be freeing some of the load on your production server. Keep in mind that the clone action is the most resource intensive action in Stash, and is the number 1 item to consider when selecting your hardware.
