It was decided to have task only in one backend (if I remember, the
discussion was mainly with JML).

My suggestion for now : 

1) consider that each task is in one backend and only one.
2) backend number should be unique (use uuid)
3) stay with the task@backend TID for now.
4) For retrocompatibility reason, be aware that "@1" means the first
localfile

That's the easiest way I can see to go forward. We will care about other
problems later.
