How to backup samba4

[Marc Muehlfeld]

Hi,

I'm currently planing and testing the final steps for our switch to s4 in 3 
weeks and now got the following two important questions:

- How do I backup samba4 (databases, etc.) while it's running?
- What do I have to backup from samba (byside the data on the shares) to 
restore the whole AD if neccessary? (/usr/local/samba/private|etc|var + sysvol 
+ netlogon folder?

Regards,
Marc
