A method for group policy backup management in an enterprise network having a plurality of domains, comprising the steps of: retrieving a list of group policy objects for a domain; generating a configuration initialization file including a domains section identifying a plurality of domains that are to be backed up and a setup section specifying a plurality of values that control the backup of each policy object in each domain; determining a digital signature for each policy object on a list of policies for the domain; comparing the digital signature for each policy object with a corresponding previous digital signature for each policy; determining if a current digital signature for each policy object matches the corresponding previous digital signature for each policy; backing up each policy object having a current digital signature that does not match the corresponding previous digital signature; and repeating the steps of retrieving, determining a digital signature, comparing, determining policy object matches and backing up for each domain in the plurality of domains.
