Backing up Active Directory

I'm trying to backup Active Directory on two Server 2012 domain controllers.

I tried using Arcserve backup software, but when I run a test restore (from Arcserve) the System State folder and sub folders are empty. Not sure if I need an agent for Arcserve to backup Active Directory.

Can I backup Active Directory running on the Server 2012 domain controllers using Windows backup and then backup the Windows backup file to tape using Arcserve?  Would I be able to restore Active Directory from the Windows backup in the event that both domain controllers went down?

Thanks,
cja

Hi,

Windows backup supports backing up AD Services, so yes, you can use it to backup your Win 2012 DC. After that you can of course copy/backup to some additional tape.  

There are MS procedures for backup and restore, and are described at following articles:
Backup: https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/manage/ad-forest-recovery-backing-up-system-state
Restore: https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/manage/ad-forest-recovery-perform-a-full-recovery
Restore of AD services: https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/manage/ad-forest-recovery-nonauthoritative-restore

Regards,
Ivan.

Should I run the backup on both domain controllers? One being the FSMO and the other being the secondary?

I set up Server Backup to backup AD daily to a second drive installed in the server.  Where can I find the backup files so I can back them up to tape using Arcserve?

Windows backup takes control of the whole drive so don't think you can.

Depends on your RPO/RTO.

Do you have AD Recycle Bin enabled?

I found the folder called WindowsImageBackup and set that to be backed up to tape by Arcserve.

Thanks for your help.
