Prevent Active Directory SYSVOL Replication

Globally we have around 8 AD servers, Last week all sudden one of our ABC Domain Controller got some drive issue where SYSVOL stored. Problem is after several hours all the scripts and gpo folders are missing in other 7 Domain Controller's, but ABC DC has all the folders also we noticed lot of DFS errors and blocks on the D drive errors on ABC domain controller. To fix the issue I shutdown the ABC DC and restored sysvol from backup.

I need help how can we prevent these type of issues where one specfic DC got some issue and impacts all other domain controllers, all gpo&scripts are missing in SYSVOL which cause major issue. All our 8 server global catalog servers.

OK, How about keeping PDC in data center and DR Global Catalog, Other 6 sites with Read Only Domain Controllers... Will this be a good approach. Because we have don't have control in other 6 sites as its managed by different teams.

Maybe but we can't really say. That's a big AD architecture question and would require getting to know your network, management structure, physical layout, security, and business requirements.
