I just read a few days ago how Google would be adding gmail to there data download page.
Heck I did not even know this google data download page even existed. Just checked it again tonight and see they now have gmail added to it.https://www.google.com/settings/takeouthttps://support.google.com/accounts/answer/3024190?rd=1
I'm a big fan of gmail and have been using it for many years along with a number of other google services.
I'm also a big fan of having multiple backups. Not only a fan up backing up but also of making sure my backups work.
Anyway thought I would share...
