@d_rift My understanding is that theres the stuff that is backup up to signals servers & protected by the magic of Intel SGX & (by default) a short PIN (can elect to use a long password/phrase, but most people will go with the default) - SGX private keys can and have repeatedly been extracted from hardware. Think this backup is list of contacts and groups you have and maybe your profile details (name, image)? Pretty sure the other backup of messages ,which I think can only be done manually and locally (actually I see they also have a beta e2ee storage service option for this now, Im not sure of details), is where your encryption keys are transfered. Which means your contacts dont get told your safety number has changed. Restoring this backup to a new device/client used to be painful and prone to failure for a number of reasons. Had to do incantations including granting Signal a lot of permissions you may not have otherwise wanted/needed for it to work. Thankfully much smoother now.
