Back up Gmail on your PC with Gmvault

A capable, free, cross-platform tool, Gmvault makes backing up and migrating Gmail accounts a breeze.

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.

Unlike Spanning Backup,
Gmvault won't back up your calendar or other Google Apps information: It's strictly for email. So far, it doesn't
have is a GUI: It's a console application, and you interact with it by typing commands into a little black window.
This may seem intimidating if you're not used to working in the console, but you need only a couple of commands:
Sync (for backing up) and Restore (for pushing messages back into Gmail). Like Spanning Backup, Gmvault doesn't
even ask you for your Gmail password: It uses OAuth, so it pops open a browser window, and you just log on to your
Google account and click a button to grant it access. If you don't like OAuth, you can manually enter your
password, but that method is less secure.

When you give Gmvault a command, it sets to work, scrolling Matrix-like log lines across the screen as it
downloads your entire account, message by message. Gmvault's internal flat-file database preserves each downloaded
message as two files: a metadata file, and a gz file containing a zipped copy of the message itself. Gmvault's file
system is sensibly organized, and each month gets its own folder, so you can get at the messages manually using Total
Commander
or another file manager that handles gz files well. You can also disable compression, if you
like.

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.
