Back up and Use Gmail Offline
The reason it always seems like your Internet connection goes out at the worst possible time is because when you stop and think about it, there’s really no good time to be without Internet access. Whether we’re trying to play an online multiplayer game or collaborate on a cloud project, losing an internet connection sucks. That doesn’t mean you can’t still be productive, however, because Google has made it possible to use your Gmail account offline (provided you use Chrome). Here’s what you need to do.
Log into your Gmail account, click on the Gear icon in the top-right corner and select Settings, and then click on the Offline link. If you see a blank page, select the Install Gmaill Offline option and proceed to do so.
After you install the app, launch it and follow the prompts. The first one will ask whether or not you want to allow offline mail. By choosing the Allow offline mail option, Gmail will save copies of recent mail for your account to your PC. You can then choose to download from the past week, 2 weeks, or month by clicking on the gear icon in the upper right corner.
At this point, the synchronization process will kick in. Depending on how much email you’ve acquired through the years, this could take a long while, even on a fast connection. Once it’s finished, however, you’ll be able to access all your mail offline.
What if you’re not using Google’s Chrome browser? You can still backup your Gmail and view them offline in a third-party email client. Here’s how:
Download and install Gmail Backup from here. Run the program, input your username and password, and choose a directory to save your mail. When you’re finished, click the Backup button and Gmail Backup will do the rest. Should you ever need to view these messages offline, you can do so in Outlook and other clients that support the .eml file format. But what’s even cooler is that you can restore your local emails back into Gmail just by clicking on the Restore button.
