You are right. The primary purpose of those APIs was the use with the GUI, so
this was never an issue for us.

Returning an ID is not an ideal solution, because an API call can fail. In
that case you do not know the ID anyways, but the resource could be
created anyways (i.e in case of network problems).
But why do you need to know the backup ID exactly?
