Allow any SQL user to create database as copy
According to http://msdn.microsoft.com/en-us/library/windowsazure/hh852669.aspx one of the backup strategies proposed is to copy the database. If that is what is proposed officially, then you can count on people writing scripts, services, worker roles, etc to back up the database. Using the equivalent of the SA to do so is just unacceptable solution. If my code is compromised then I am exposing usernames/passwords (encrypted or not). Furthermore, it's not like I can just remove that user and replace him for some other user.
We should be allowed to set specific roles to any users so they can copy the database.
We understand the scenario here, there are some constraints here as any user would be able to impact the bill here. That said we are actively working in this area, please stay tuned.
