I may need to visit the United States briefly, therefore I want to offline backup my text messages and signal messages from my GrapheneOS phone. Once I return home I want to restore my data from the offline backup. Does anybody have experience and recommendations for this?

      Wouldn’t be so sure about the 45 days for Signal. Had to do an “emergency” reinstall of Signal at one of my family members. All messages were lost.

      However, Signal has a dedicated backup-function baked in that I’ve used before. (See under Settings > Chats) It should just do want you want.

        Aren’t signal messages dependant on the same password “key” being used to decrypt the messages.

        I’m still new to signal and still playing

          You are right, basically.

          However, the backup solution of Signal will basically export the “content & metadata” of the messages into a re-importable format and then bundle everything into an encrypted container. You will get a separate password for that container file that you need to re-import your messages.

          As far as I understand it, Signal will then re-encrypt your messages after the import with the key of your new Signal installation.

      I tried backing up to seedvault through USB once, that did not work at all lol idk where exactly the issue was but the USB would get warm and eventually fail but I could write so much more data to the USB on a computer so it had to be something with the phone.
