Create or restore Sophos Firewall backup

In this article, we will show you how to backup and restore a Sophos Firewall wall using Sophos Firewall OS.

Note: In any case, we recommend that you regularly back up the Sophos Firewall. With a backup, you can easily import the configuration onto new hardware in an emergency and be up and running again in no time. However, a backup can also help you to go back to an earlier version in case you might have made a mistake during configuration.

Create backup

Log in to your Sophos Firewall and select Backup & Firmware from the left navigation.

Manual backup

If you just want to make a quick and easy backup of your firewall, just click Backup Now. You can then download the backup to your computer.

Automatic backup

So that you do not always have to perform these backups manually, you can set the firewall to create a daily, weekly or monthly backup of the config. Select your desired option at Frequency and then click Apply to save the settings.

The automatically generated backups can be stored either locally on the firewall or on an FTP. The third option is to send the backups by e-mail. Unfortunately, unlike the UTM, it is not possible to encrypt the backups here, which is why we do not recommend this method at this time.

Update: As of SFOS version 17.5.4, backups can now also be encrypted on the Sophos Firewall. From our point of view, there is no reason why you should not have your backups sent to you by e-mail.

Restore backup
