Yes, the daemon needs to run as a user who has permission to update the
desired files.  If the homedirs need to be usable as-is on the
destination, your best bet is probably to run the daemon as root.  On
the other hand, if you're just making a backup, you could run the daemon
as an unprivileged user and still record the original ownership using
--fake-super.
