@Nikola,

Backing Up the Samba DC:

Here is a step-by-step process for backing up an existing Samba Domain Controller (DC) and restoring that backup to a new server installation:

1. To prevent data corruption during the backup, stop Samba services on the existing DC.

$ sudo systemctl stop samba

2. Copy the Samba configuration file and any other relevant configuration files to your backup location.

$ cp /etc/samba/smb.conf /etc/samba/smb.conf_org

3. Next, use the samba-tool utility to back up the Samba Active Directory database:

$ sudo samba-tool domain backup offline --targetdir=/path/to/backup/directory

4. If you have specific files and shares you want to back up, make copies of those files and directories to your backup location.

Restoring the Backup to a New Server:

1. Install Samba on the new server.

2. Copy the Samba configuration file (smb.conf) from your backup to the new server’s /etc/samba/ directory.

3. Use the samba-tool utility to restore the Samba database on the new server:

$ sudo samba-tool domain restore --backup=/path/to/backup/directory

4. Start the Samba services on the new server:

$ sudo systemctl start samba

By following these steps, you should be able to successfully back up your existing Samba DC and restore it to a new server installation while preserving your Active Directory domain and file shares. Remember to adapt these instructions based on your specific environment and requirements.

Can you please describe a process of backing up existing Samba DC and restoring that backup to a new server installation?

Hi! Did you find anything with LDAP auth?

I have tried and it didn’t work below was a detailed query on askubuntu website.

https://askubuntu.com/questions/1415706/how-to-use-my-existing-windows-server-2016-r2-standard-active-directory-to-authe

It would be very helpful to explain how it works with a systemd Networking configuration.

With krb5.conf there are a lot of workorounds to make because Samba got some bugs to handle.
