@Izzy I don't understand his question at all.

@DanHulme As I understand it, OP wants to configure bmgr so it restores all apps and their data backed up from device X and user A. To me that somehow implies multiple users on the device (otherwise there'd be no need for the "user A" condition).

Just thought you might be able to help there (thinking of your answer to my "multiple devices backup" question. If not, my bad :) Thanks anyway.
