Hi guys,
You're saying to do snapshots of AD without the Quesce mode, but isn't AD VSS aware (along with SQL, Exchange & sharepoint being about the only other products that are aware)?
My biggest troubles have been with AD when I DON'T quesce the server at snapshot time, rather then doing so!
In ESX 3.5 you could not VSS snapshot and therefore I used Backup Exec System Recovery which did so. Now that I can VSS snapshot I've not had any issues.
Cheers,
Steve
