Well, yeah, if you back it up with a 3rd party backup tool, you are trusting the 3rd party.<p>I recommend you make a backup to your laptop, which you then encrypt manually. That way the trust model is: you trust yourself. Then you can do whatever you want with the encrypted file. Apple&#x27;s iCloud is perfectly fine at this point.<p>The real challenge is to find a way to restore that backup, because you have to be on a computer you trust. If you decrypt the backup on a &quot;loaner&quot; laptop, your security is broken.<p>If you decrypt the backup on your personal laptop but the laptop has a hidden keylogger installed by the TSA or TAO, your security is broken.<p>It would be necessary to backup the phone on the _phone_ _itself_. Then manually encrypt the file (easy to do). Then upload to iCloud. At this time, no such app exists for iOS.<p>Since you plan to restore the backup to the phone anyway, it&#x27;s no problem to decrypt a file on the phone before using it for the restore.
