I'm very sorry to advise that this script is not race-free in the
locking done on the AD databases, which is why we have written the
'samba-tool domain backup offline' tool which holds the correct locks.

You should only need to back up the domain on one DC as long as you are
confident the DC is correctly synchronised, including sysvol.
