I bet you did not know you could backup ALL your gmail correspondence with one nifty application. I did not either. Until today, when about 150 000 gmail accounts representing less that 0.08% of all Gmail users were reset to ‘0’.
In the meantime, those concerned about safety of their gmail accounts may use app called Gmail Backup. It is available for Mac, PC and Linux. It might take a while to back up and download all the mail you’ve got but it’s definitely worth a shot. I know I am downloading it already.
