Finally Google admits it has to centralise its backup process, maybe now we'll see a single decent app for getting data on/off an Android phone and people will be happy about it.
This is a pretty significant policy change by Google, from we don't manage things centrally to this. This isn't so much a feature, but Google getting their heads out of their own asses and recognising that at least some kind of central control on the beast they created is a good thing.
