How to synchronize many disconnected Stash instances?

Question

I (shortly will) have Stash instances on several disconnected networks (no Internet, no connection to each other) , each containing a large number of projects and repos. What's the "Atlassian" best way to synchronize these repos on a weekly (or daily) basis?

I am writing some custom shell scripts that use git bundle in order to meet this use case. I am unsure if I will be permitted to post these to GitHub, although that is my goal.

Hi Brandon,

There isn't really much in the way of help that Stash can provide if the networks are separated like that. But you can utiise the distributed nature of Git to make things easier. You could have a repository on the the drive for copying, and just pull changes from the home network to the device, and then push it back onto the destintation. This will work just fine when you don't make changes on the destination, but my comment above still stands when there are, and you may have to deal with merge conflicts. The nice thing abou using Git like this, rather than just copying files, is that Git will tell you when you get conflicts without you having to think about it.

I hope that answers your question?

Currently, source code 'lives' in its home repo on a given network, and gets transferred / copied / synchronized (via sneaker net - the networks are not physically connected, so mirroring probably? won't work here) to repos on other, disconnected networks. Usually, the synchronized code is just checked out of the destination repo only so that other code may be built, but sometimes, bug fixes and changes are checked into the destination repo, and rolled back to the source repo. Ideally, we would just compile all our source on its home network, and transfer artifacts around, but we're not there yet - this is related to my other recent question: https://answers.atlassian.com/questions/163199/stash-using-managing-multiple-repos-simultaneously
