This is very strange, as I said, I have been using a script to backup my
domain using 'samba-tool domain backup online' for the last 2 years, without
problem.

My Unix domain member is using Samba 4.18.8 on Devuan 5 (daedalus) My DC
with the PDC_Emulator role is using Samba 4.17.12 on Raspberry pi OS (64bit)
11 (bullseye)

What versions of Samba are you using and on what OS ?
