restore AD

I' would try to make a disaster recovery of my Domain Controller.
I make a full backup in the week-end and each day a differential incremental backup of my DC.
If I want restored the active directory, I must use differential incremental backup or the full backup?
thak's a lot

Re: restore AD

Hi Andrew,

Active Directory depens upon the NTDS.dit file.
Entire NTDS.dit is backed up even in incrementals.

But also you would require the other files too.
You will have first to restore the FULL backup then restore the incrementals in order.
What kind of incremental you use differential or cumulative
If its differential then u will have to restore all the incrementals in order.
if its cumulative then only the most latest incremental after the Full backup would be required.

Do not perform AD restoration using authoritative mode unless you know what you are doing....

Re: restore AD

AD is backed up with the System State. I would recommend getting familiar with this:
