Backing up your Mozilla Thunderbird profiles and emails, especially those placed into local folders, is an essential step to ensure your data is secure and can be restored in case of data loss or migration to a new computer.

It used to be quite difficult but as of December 2023, the process has improved quite a bit.

Here’s a step-by-step guide on how to do it:

Backup Thunderbird Data Manually

1. Locate Your Thunderbird Profile Folder:
   • Thunderbird stores your data in a profile folder, which contains your emails, settings, and other personal information.
   • To find it, open Thunderbird, go to Help > Troubleshooting Information, and under the Application Basics section, click on Open Folder next to Profile Folder. This will open your profile folder in your file explorer.
2. Close Thunderbird:
   • Ensure Thunderbird is completely closed before proceeding to avoid any file corruption. You can do this by exiting the application and checking that it’s not running in the background.
3. Backup the Profile Folder:
   • Copy the entire profile folder to a backup location. This can be an external hard drive, USB flash drive, or a cloud storage service.
   • It’s important to copy the entire folder, as it contains all your emails, settings, and other data.
4. Backup Local Folders Separately (Optional):
   • If you have emails stored in local folders and want to ensure they are doubly secure, you can locate these within your profile folder (typically under Mail or ImapMail folders) and copy them to another location.

Using a Backup Tool

Alternatively, you can use a third-party backup tool designed for Thunderbird to automate the backup process. Tools like MozBackup (for Windows) or MailStore Home can simplify backing up and restoring your data. Follow the specific instructions provided by the tool you choose.

Restoring Your Backup

To restore your data, you would:

1. Install Thunderbird on the computer where you want to restore your data.
2. Close Thunderbird if it’s running.
3. Locate the profile folder on the new installation.
4. Delete its contents and replace them with the contents of your backup.
5. Start Thunderbird, and your data should be as it was at the time of the backup.

Tips for Successful Backup and Restore

• Regularly backup your data to minimize the loss in case of a failure.
• Verify your backup by occasionally checking that the copied data is accessible and not corrupted.
• Keep multiple backups in different locations for added security.

By following these steps, you can ensure your Thunderbird profiles and emails are securely backed up and can be restored when needed.
