Imagine an application that lets you effortlessly back up your gigantic Gmail account to your computer in one fell swoop; that can move your entire email history, labels and all, to a new Gmail account at the push of a button; that is completely free; that works across Windows, Mac, and Linux; that takes less than a minute to configure; and that doesn't require administrative privileges to install and use? If that sounds too good to be true, you'll be be very pleasantly surprised with Gmvault.

Gmvault doesn't have to download your entire history: I tested it by downloading just the previous two months of email in my account. The total came to 13,546 files (from 6773 original email messages) occupying 268MB of storage space. It did get stuck once during the download, but I simply terminated the operation (by pressing Ctrl-C) and then ran the same sync command again. The download took a couple of hours on my not-very-speedy Internet connection, but it completed the job without a hitch and without interrupting my regular Gmail workflow.

Next I created a new Gmail account, and used Gmvault to "restore" (shift) the email messages to the new account, to simulate a migration. I aborted about 3 hours into the process, after becoming convinced the process works very well (I didn't really want my email to migrate to a new account). Messages uploaded without a hitch and with their original labels and other metadata perfectly intact--except for importance markers, which are not included in the process. All in all, it was a stellar performance: Gmvault worked exactly as described, and with virtually zero annoyances. The only problem I ran into was that the upload process severely congested my broadband connection, making it very slow; but you could avoid that issue by running the restore process overnight (or over several nights).

Gmvault is open-source, and the project accepts donations.

Note: The Download button takes you to the vendor's site, where you can download the latest version of the software.
