I think this is a crap scenario. Yesterday a client accidentally cloned a vanilla switch to a prod switch while attempting to go the other way. This blew out the config in the cloud. Without a local configuration backup, we had to redeploy the entire network. I understand there are 3rd party tools like Auvik to do this, but not every client is going to want to pay for that.
There needs to be a way to generate a backup file, or at lest a repository in the cloud for them to be saved. It didn't help that the Meraki support engineer had us break the stack which them wiped the other switches in the stack. It was an overall horrible experience with Meraki.
