At some point I turned on backup, and now find my account over the 3T budget. So effectively DB has stopped working. The problem is that I have no memory of what computer is backed up. I've disconnected all but two. There seems no convenient way from the web app to turn this off or delete the backup. Neither of the connected machines seems to be the one I backed up. I have been unable to download the files from the web just to get at them. So my questions are 1) is there a way from the web to disable/delete the backup? 2) is there a method that if I disconnect the final two machines to delete the backup and reconnect will Iose all those unsynced files? 3) as a desperate measure, is there a way to transfer to a new account?
