It seams that Oandbackup is not able to restore accounts. With DAVdroid I had the Problem, that the account after restoring not appeared but DAVdroid was also not able to create new Accounts because an Account with these Name already existed. At the end I had to remove the Account database file manually to get Apps work again.
