Problem Description: If I try to do a backup of all instance setups I get an empty backup file and no real console output indicating as to why no backup is created.
The zip file is made however it only contains this
ADS (The top level panel you access) is actually an instance in itself.
Creating a backup there would only backup the contents of ADS, not all the underlying instances, which is why it results in an empty backup.
You would need to take backups individually inside of each instance, or if you are looking to back up the entire datastore do so directly on the filesystem (Making sure you only touch the amp datastore as the AMP user)
