Undo / Roll Back

Question

Is there a versioning feature where we can rollback to a previous verion of a Group e.g. A group with 50 members was modified, however the changes done had an error and we need to roll back the changes, is that possible?

(very strong) assumption1: changes were done via ARS door only, and not DC directly with native rights. 
 ARS does contain Change History holding old and new value of attribute. I guess, though no full list of members for group membership changes and therefore, you will never know the full group.members list at Time=T0. You need separate solution: for example EReporter or RMAD (very easy to use for your case). 
 Legal Compliance: assumption1 + restore group membership based on ARS information will makes legal compliance to be violated. (not sure is it the case for you).
