Losing data

Hello every one, I created a form for data after entry the data I did some changes in the form, unfortunately some data hided from the columns that I bring changes, how I can recover them again?, I did not backup from my data before the changes.

@pouyaedris, what is the tentative number of cases missing from your server? Could you also share some clues of how you identified the missing cases in your dataset? Screenshots should be helpful if you should have any.
