Every time a change is made, the old version of your information is saved, giving you the ability to Rollback to a previous time stamped version. And all from a convenient drop down menu.
Reinstate deleted items
Additionally, Rollback saves an item as it is deleted, so that you can reinstate an item that has been unintentionally deleted from the system. To restore an item from rollback, go to the activity page, find the log entry for the deletion of the item, and click on the restore button.
