What folders should be backed up on a 2012 Server FSMO Domain Controller

What folders should I backup on the 20102 Server FSMO domain controller so that I could restore the domain if both DC's went down.  Currently I'm backing up to tape.


Thanks,

Backup system state of fsmo holder server daily, it contains all ad configuration and you can restore system state in case required

Also backup system state of adc as well

U should always take system state backup of pdc and one adc

AttachedBackup.pdf is a picture of what is being backed up on the FSMO DC and the other DC.  Is this correct?
Mahesh

The fsmo server is backing up wrongly
Use system state backup instead for fsmo server as well

The tape drive is connected to the other DC and the FSMO is being backed up from it.  I do not see the "system state" folder on the FSMO when I browse from the backup program.   What folder on the C drive of the FSMO would hold the system state information?
Mahesh

U need to connect to client agent of fsmo server, then only you can get system state option

Just to clear up the confusion: system state isn't a set of folders. It is a particular type of backup. When a backup program (or client agent) performs a system state backup, it uses windows APIs to tell the system it is performing a backup and the OS does some cleanup and database work to ensure the entire backup is in a consistent state.

Most programs that use database backends need this treatment. That's why your agent has special categories for Exchange (uses a database), SQL, and SharePoint. You can't just back up a bunch of folders for exchange either. The agent has to tell exchanhe to reconcile, thus the special category.

To back up a domain controller, you need to back up system state. And that'll require an agent on the machine, not just a bunch of folders over the network.

So I need the Arcserve agent installed on the FSMO?

If I'm backing up the System State on the other domain controller, not the FSMO, is that sufficient to restore AD if necessary?

Thanks

Ok. I transferred the 5 FSMO roles to the DC that has the tape drive attached and will backup the system state on that DC.

Should I backup the SYSVOl and NETLogon folders on the other DC that DOES NOT have FSMO roles?

Thanks

I meant to give Mahesh credit for the answer. I clicked the wrong expert. How do I correct this?
