By default the 2008 R2 AD has recycle bin disabled, and if enabled it cannot be disabled. So, quick question is it a good idea to have the recycle bin, what sort of complications we might face if something goes wrong and a recovery of the entire AD is needed.
Plus what is the best method to backup AD, I have AD running in a Hyper-v and I do not think making snapshots of the hyper-v is advised, so would a system state backup using windows backup feature within the hyper-v be the best way to keep AD backups or is there something else out there to have a healthy AD backup system.
