Tue Jun 18 09:28:38 UTC 2019

Hi,
first online backup works, but why some parts are missing?

Online:

root# samba-tool domain backup online --targetdir=/mnt/backup/online/ 
--server=DC -UAdministrator

Backup created 2019-Jun-18 11:04:19
Using samba-tool version: Samba 4.10.2
Domain online backup, using DC 'DOMAIN'
Backup for domain DOMAIN (NetBIOS), DOMAIN (DNS realm)
Backup contains domain secrets: True

missing files:
bind-dns/ folder is empty no DNS Records will be saved (not fine)

pritave/tls folder is empty my self created and samba created certs wont 
be backupped

sysvol is not included

but i thing this is right cause online backup :)

Offline:
tryed with running and stopped samba processes
do i need to stop named also when running with bind_dlz?

samba-tool domain backup offline --targetdir=/testfolder
