yeah, that would be nice but it might make the configuration a bit hard to explain.
I also don't expect people in general to use more than one backup, or 2 at most, so not having a default would't require a lot of duplication.

I was actually thinking to make them slightly bigger (e.g. 2x) as the latency between sites is much higher than local.

Specifically suggesting to add  the element stateTransfer with the attributes timeout and chunkSize. Please let me know what you think of it.
