From your link, I wish they would answer this, and they've been asked numerous times, and to my knowledge have avoided the question (which is very concerning to me): >This is excellent news! Will there also be official documentation on the backup format, potentially even official tooling like signalbackup-tools[0] to access/parse backups offline? I'm asking because, having used Signal/TextSecure for 10 years now, my backups are worth a lot to me (obviously) and there have been times when I would have liked to mine & process my backed-up data. (Extract media from conversations in an automated manner, build a more elaborate search, …) I'm like that poster and backup all my chats obsessively, since way back in the day, and experienced a period with Signal where it was impossible for me to access my own data because of their position.
