Domain controllers as VM's

Stanleyj

Almost all of our domain controllers are VM's running on ESX4.1. We are running netbackup version 7.0.1 and i wanted to see if anyone had any thoughts on proper procedure for backing these up. Whether it is better to backup using the system state method or if backing up the entire VMDK file using the VMware snap method is ok.

It is not reccomended to backup a VM running as a DC using vstorage api's as it can cause all sorts of issues like AD corruption! Microsoft do not support this either  http://support.microsoft.com/kb/888794

We tried this and the domain controllers pause for a split second and it made them not work correctly afterwards!

I'd use two backup approach.

One, full backup for DR purpose using VMDK with Full-Mapped-VM type of backup

Second, backup of Shadow Copy Components with client inside VM for GRT, and/or system state purpose.

Could the snap of the VMDK file possibley cause an issue with the backup of the shadow copy or vice versa?
