Where would you save the back up?
And would it be different with an iPhone? (does Apple even let you choose where you save stuff?) Thinking about family members with iPhones.
It's a shit story is the answer.
Signal backups today:
- Must be manually made by pushing the create backup button
- Are stored in a folder of your choice locally
Actually saving that file off of the phone is an exercise left to the owner of the phone. I upload mine to Google Drive, but it doesn't do this automatically.
I see some guides online suggesting the install of an app that will sync any folder on the phone into Google Drive, but I do not let any apps other than Google Apps access Google Drive so I do it manually.
The backup file is encrypted, so it doesn't matter where you put it... you should just get it off your phone somehow.

That's definitely the warning for Signal.
It's secure... very secure. If you fuck anything up but have your phone number then you can always access your account and create new messages. But virtually every other scenario is "unless you manually made a backup and have your backup passphrase, then you have lost your chats". Even adding new devices is "your chats will resume here but you cannot see history on a new device".
This is an extreme take on the security vs convenience question... and if you use Signal you need to keep it in mind.
