Signal's backup is different than what Telegram provides, based on what I read on their webiste: https://support.signal.org/hc/en-us/articles/360007059752-Ba...

On Telegram, login on a new device and you can see your all messages automatically. On Signal, you seems to need to perform it manually, and your history will lost forever if you phone are lost or broken.

I think the first kind of "backup" is what most people would expect, because it is convenient. But to provide this convenience, it can't be full E2E, so Telegram supports secret chat when you need max security if you are willing to sacrifice convenience.

You can get the same convenience with the Signal/Whatsapp E2E type of app. All you need additionally is to keep a passphrase stored somewhere. As long as you do that you can have automatic backups that allow you to setup a new device without access to the old one and get all your history back, without losing the E2E encryption benefits by having unencrypted backups on a server somewhere. Signal UX for this is poor though.
