ArcMap should automatically backup ongoing edits

Idea created by ghellyer on Aug 7, 2015
    ArcMap should automatically backup ongoing edits/analyses.  So many of us have lost hours of complex edits/analysis because ArcMap crashes and no backup is available.  Best would be an autosave while working at a user specified interval e.g. 15 minutes.  Alternatively, or additionally, when ArcGIS crashes it should do what Microsoft Office does and save a current version of the map/analysis.  Then when we open ArcMap it should prompt us to load the saved version, or to revert to the original version of the map/analysis.
