The Big Fritzbox update has arrived: you must do one thing first
The good news is that the Fritzbox offers an integrated backup function under “System” in the “Backup” section. There, go to the “Backup” tab and assign a password that protects the backup file. Take a secure password that you don’t use anywhere else and save it to your password manager of choice. A good solution for this is, for example, KeePassXC.
Once the password has been assigned, click on “Save”. The backup now needs to be confirmed, which can be done either via a phone connected to the Fritzbox or by pressing a button on the Fritzbox itself. On a phone, enter the number sequence displayed, for example *18653. If it worked, you can save the backup locally. You will then find a file with the extension “.export” on your system.
By the way, restoring a backup is just the opposite. There is a “Restore” tab on the Fritzbox for this purpose, where you feed the export file again, for which you need the password. Note: You can restore the full backup on the same Fritzbox model, on other models only part of the backup may be available, depending on the range of functions.
