# How to effectively backup your emails

For quite some time, I have been setting up systems to backup my data of my computer, as well as fetching data from services, such as Trakt, Last.fm or GoodReads. There’s always one kind of service that has been on the back of my mind for a while to backup, but I’ve never got the time, nor the will to do so: email!

Email is fundamental nowadays and it is the basis of Internet communication. Almost all online services require an email, and even though we use it virtually every day for the most varied services and uses, it is not the easiest thing to backup.

Fortunately, I recently came across this post by Diane where they explain how they are backing up their emails using getemail.

First of all, start by installing getmail. In my case, since I use macOS, I will just use the pre-built brew package. For other platforms (since it uses Python), I recommend taking a look at their website.

brew install getmail


Now that the tool is installed, it’s time to configure it. First, create the directory where we’re going to store the configuration. By default, that directory is ~/.getmail and the default configuration file is getmailrc.

mkdir ~/.getmail


For my specific case I am creating different configuration files and I want to archive my Gmail data at ~/gmail-archive. To do so, I create that directory, as well as three other directories inside of it:

mkdir ~/gmail-archive
mkdir {cur,tmp,new}


This will ensure our directories are compatible with the maildir format we’re going to use to store the emails. Don’t worry! They’re all plaintext and easily searchable from the console line or any other tool you might want!

Now, let’s create a configuration file for Gmail at ~/.getmail/gmail.conf. On it, just copy the following configuration and change the user, password, and path to match what you want.

[retriever]
type = SimpleIMAPSSLRetriever
server = imap.gmail.com
mailboxes = ("[Gmail]/All Mail",) # To pull all emails
port = 993

[destination]
type = Maildir
path = ~/gmail-archive

[options]


As you can see, I’m using IMAP retriever. However, there’s a few other options, with and without (don’t!) SSL.

If you’re using a service other than GMail, please change the mailboxes variable too. You can write mailboxes = ALL and it will download all the available mailboxes. By default, it downloads INBOX only.

Now, to fetch your email, just run:

getmail -r ~/.getmail/gmail.conf


Et voilá! You have your email backed up! You now can create more configuration files if you want for different accounts and set up a cronjob to execute this command.

I really hope this will be as useful for you as it was for me!

Or if you don't know what a response is, you can always write a webmention comment (you don't need to know what that is).
