Correct. I actually use backup of DC's for 99% for recovery of single objects or similar. As an IT admin (before Veeam) I always had at least 2 DCs in every environment I worked for. (Some environments much more). The 1% other recovery was to build a quarantined test lab or to test if the restore of the backups worked. Something that is much simpler now with SureBackup but in my time (the good old days
) was a bit more difficult.
But this specific case was for a total loss so it is a scenario that you hope will never happen, but you need to take it into account. Even if you have DC's at different locations. You never know there will be a malware that specifically targets DC's and renders your entire worldwide environment useless in minutes.
But as said. Yes, to everyone out there. 2 DC's is indeed a must. And with today's technologies, have at least one of them (or both) virtual. On a core version to save resources
