How To Backup SAMBA Server Configuration

Hi Experts,

Samba noob here. I currently have Debian 7 with Samba 3.6.6 installed.  I've been looking around for tutorials on backing up my Samba server. I have purchased a book call The Official Samba-3 Howto and Reference Guide but was hoping to make some progress on my own before it arrives.

All I've found are the following websites:
1. Can't find the backup script in the following website.
https://wiki.samba.org/index.php/Backup_and_Recovery

2. Don't understand the part about the SIDs on this website here...
http://www.linuxquestions.org/questions/suse-novell-60/how-to-backup-samba-files-615619/

Please help point me in the right direction.

Many Thanks
Ricky

The 2 sites indeed are pointing to a right direction. You have to tell us which portion you are not finding in these 2 sites to be right.......

"Can't find the backup script in the following website"--> what do you mean by this? Is it not written that---

 "The backup script of samba isn't installed, when you run 'make install'. It's recommented that you copy it from the sources directory (source4/scripting/bin/samba_backup) to your system, like /usr/sbin, and set secure permissions: "

If you know samba well, you know where the directories and files are, just cp the directories and files......... that's all.....

Best,

Are there any thing to watch out for when performing the backup?

just copying the directories and files would do, nothing else is required. In the backup script also, you need to mention the location and the script will only work if your installation is in the same directory.

The samba configuration files live in a directory called /etc/samba - just backup that directory.

11. Stop Samba server running on the new machine.
myserver2# service samba stop

myserver2# cd /dumpbkp
myserver2# tar -xvzf sambadb.tar.gz -C /var/lib/samba
