Data theft and loss have been a rising concern in these tech-savvy times. That’s why creating a backup for emails is something Thunderbird users need to perform on regular occasions. The main idea behind taking Thunderbird email backup is to protect your valuable data from unnecessary corruption and hard drive disasters. For instance, if your machine got physically damaged, then the chances are that you would not be able to access your Thunderbird data at all. In such scenarios, if you had created a Thunderbird email backup in an external drive, you could easily retrieve them back on your new machine whenever needed. It resolves many problems, so we are here to discuss backing up your Thunderbird emails to a hard drive.

Significance of Thunderbird Email Backup

Storing Thunderbird mail backup to a hard drive has its own importance-

  • As users, we may think there is no requirement for Mozilla Thunderbird mail backup because its data is saved on the system. But in cases such as data theft, corruption, and system crashes, all system-saved emails will become irrecoverable.
  • Since the local server gets more space, the server’s performance improves immensely.
  • You can prevent data loss; having a backup means a saved copy, letting the organization continue its regular work without interruption.
  • One can quickly recover the data if it accidentally gets deleted. Backup safeguards data from all accidental loss.

How to Backup Mozilla Thunderbird Emails?

Thunderbird doesn’t provide any built-in feature to backup emails but still there are a few methods to complete task for us. Some standard manual methods to take Thunderbird mail backup are listed below:

  • Export Thunderbird Emails Using Add-on
    You must add a specific add-on (ImportExportTools add-on) to make Thunderbird functional to export emails.
  • Backup Thunderbird Profile
    Thunderbird saves the data to where it belongs, i.e., the User’s profile folder. You have to locate the User’s profile folder, copy the contents, and paste them to a convenient backup location.
  • Save emails to desktop as EML-
    Another method is to save a copy of your emails on your desktop and move it to hard drives. These copies are kept in EML format, where the content of the message, sender, receiver, subject, and date are all stored.

    We will discuss this process in more detail later in this section.
