All the other ideas are good, but you could copy your gmail straight to an on-site mailserver (even if it doesn't handle any mail, just have it there formatted) using https://github.com/imapsync/imapsync and then if your gmail got kicked, just sync the mailbox to somewhere else or set up your own mailserver (biased but prefer the latter)

I'd seriously recommend using imapsync - Sending some money to the developer will help with development, there is a goldmine of information in the FAQs section on xxx -> gmail. Good luck! FWIW I just moved a couple thousand off Gmail using the tool :) worked wonderful.
