[Samba] some questsions to online backup and a failiure with offline backup
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

offline mode?No, it is not required to stop the servers. This looks more like a bug. There may be some issues around offline backups with BIND9_DLZ, or perhaps a site-specific issue.
