Does the /autofs/backup/linux/samba_dom/backup.tgz directory actually exist
?
To me it looks like a compressed file.

I have a script that runs every hour to backup my domain and it uses
this:

samba-tool domain backup online -N --server="$PDCe"
--targetdir=/srv/backups/$(hostname -d) --use-krb5-ccache=/tmp/backup_cc

and I end up with the directory /srv/backups/samdom.example.com full of
files like this:

samba-backup-samdom.example.com-2023-11-20T12-45-15.011687.tar.bz2

I suppose I should also say that I run the script on a Unix domain member
and not on the DC.
