Why Need to Backup Thunderbird Email Windows 10?

There's a golden rule about computers and important data. If it can be lost, then it should be backed up. It's no different for Mozilla Thunderbird emails. Accidents can happen, data loss occurs, virus attacks are common, and not every network is secure.

These reasons alone should push Thunderbird users to regularly backup their data. So, when tomorrow a computer crash or virus attack happens, you can simply recover it from an external device, cloud storage, etc.

On top of that, even with thorough security of your data, such as using Windows Defender, or any other third-party software, you're still immune to malware attacks. This gives you even more reason to regularly backup your Thunderbird emails and data in Windows 10.

Now that we know what Thunderbird is and why it's important to backup its data let's talk about the ways of doing it. While Thunderbird can be backed up in many ways, we picked the three most effective ways for users to back up their emails. Here they are:

  1. Method 1. Export Thunderbird Emails
  2. Method 2. Copy Thunderbird Profile to Another Place

Method 1. Export Thunderbird Emails

The first method is also the lengthiest. This includes us backing up each of our emails or the most important ones. This method requires you to save your emails in the shape of files. Now, after you're done with this, you can do a few things with your saved files, such as:

  • Save it to an external device;
  • Upload to a cloud service;
  • Save it on another computer.

So, in order to be able to do that, here's what you'll have to do:

Step 1. Open Thunderbird and sign into your account.

Step 2. Choose the Inbox or any other subsequent folder you need to backup.

Step 3. Select one or multiple emails that you'd like to save.

Step 4. Click on the "slash button" to trigger the pop-up menu.

Step 5. Pick Save As then click "File".

Step 6. Pick the folder where you wish to save your files.

This will help you save your files in the common email format. You can open those files in common email programs like Outlook, Gmail, and Thunderbird. So it is important for you to know how to save Outlook emails to hard drive. However, it's imperative that you save these files to a secure location and that you regularly update them to ensure backing up the latest files when needed.

Method 2. Copy Thunderbird Profile to Another Place

A Thunderbird profile is a file extension only readable by Thunderbird. This File saves all your information, including login data, inbox emails, sent emails, drafts, etc. So, saving this profile file alone can help you save your files and create a viable backup.

So, how exactly do you find this File and save it? Here's a simple method:

Step 1. Press "Windows + R" to bring up the Run command.

Step 2. Type “%appdata%\Thunderbird\Profiles” and press "enter".

Step 3. Find the folder with the default extension.

Step 4. Copy and paste it into a folder of your choosing.

Now, there are many cases of Windows 10 versions, and the latest release of Windows 11 annuls this process. Simply because your Profile.ini might not be saved in this location. In order to find the location of this File, here's what you'll do:

Step 1. Open the three-slash menu in Thunderbird.

Step 2. Head into Troubleshooting information.

Step 3. Find the Profile folder, and click "Open Folder".

This will most likely bring you to your Documents/Thunderbird. So, once again, find the Profile.ini file and save it to your chosen location. Then, upload it to cloud storage or save it to an external device. But, make sure you do it regularly to keep your backup updated.
