Every now and then, GMail gets weird, and insists I re-login using an almost unreadable captcha. A couple of times I said my account was suspended but then presented a login with no captcha which worked fine. Which is more than a bit unnerving.
So, I wondered, how can I back up Gmail? It’d be nice to have a backup system in case GMail is down or I get locked out. As it turns out, it was easy. I imported all my addresses and email from GMail into Yahoo Mail then told GMail to forward all email to Yahoo, keeping a copy on Gmail. Thus, I now have two email systems, that with a little maintenance each week, will be in sync. Backups are always a good idea anyway.
