First of all, why would you want to copy Virtual Hard Drive (VHD) or a blob from a Windows Azure subscription to another? It could be for: doing backups, because your Windows Azure trial is ending, to get a copy of a client’s VM to investigate a problem. So, when one of my client asked me if it was possible to do it, my answer was: “Yes it is, using command line tools”. But since he was looking for a simple solution, I wrote him a little script that I will share here so everyone can enjoy it.
Get Started

Get the source
