We recently had a sys admin from another division let go. Although his core duties were for his division, he oversaw different tasks for other divisions. He set up our domain controllers to image using symantec besr. My question is, in a scenario where a DC goes down, am I not committed to *only a non-authoritative restore of the domain controller since I will be restoring from a static image? In other words, is this even a good practice? Shouldn't I be using *only MS proprietary backup methods (i.e. NTbackup.exe)?
If my current recovery process is good, won't I still have to utilize directory services restore mode, etc?
