Problem/Bug Is it possible to recover corrupted world with all items?

Electricity got shutdown today,and i was hosting a server to play w/ my friends
When electricity switched on,when i logged into our server and noticed that every chunk in our area got messed up.Is it possible to recover,and could u recommend any auto-backuping plugins for not making this happen again?
