Today my virtualbox was halt and I did the poweroff and didn't care it have checked on,( I always avoid use poweroff so it still check on as 4 month ago),maybe I was too tired, I realized immediately but it was too late only 1 second without any warning,my four month works has gone. Didn't backup more often is my critical mistake. some project under subversion manager could recover to 3 days ago. but experimental project and code, new research document an so on which didn't backup have to rewrite.
Please add a warning when do the revert or some other destroyed method. Thank you.
