Accidentally cleared my flight log..

How did you "clear" it? Was it synced to the cloud?
 
Im guessing not, I was fumbling around with the User Center, and hit "clear local cached records", didn't have my glasses on and hit yes insted of no . I hit the cloud and it went through the 100% process, but did not restore my previous flights.. do you have to be linked up and everything powered on for this to work?
