Soon we plan create a two way trust between our infrastructure and the infrastructure of a new company acquired by our MD.
Our AD servers span across two cities so my question is before creating the trust how should I Backup my AD?
- Do I perform system state backup on each of the 10 DCs or doing it on DC with FSMO roles will be sufficient?
- All our DCs are Windows 2008 R2 so should I take snapshot using ntdsutli?
Please advise because in case things go wrong I know I can simply revoke the trust but just to be on the safe sideI would like to backup our single domain AD.
