[Samba] how to create a backup domain controller

[deepak prasad]

Hello everyone,

I am using samba4 as my Primary Domain Controller in my company. But I am concerned if my DC goes down due to some reason then is there any way I can create a Backup Domain Controller or Secondary Domain Controller which can be used at that moment of time so that all my users can login to their respected machines with all the policies. I don't want my organization's work to be hampered in the mean time.
