That's essentially an Android system backup, i.e. a disk dump of the app data folder, right?

Almost nobody uses these in practice, so I think my point largely still stands.

I'm pretty sure that, given their stance on this issue on iOS, they'd start locally encrypting the message database using a key stored in the Android Keystore system (which won't be backed up or extracted).

No, and automatic backups are on Signal desktop as well. They are also supported by this tool.

No as in, this is not the Android backup system, but rather something custom-built by Signal? If so, how do I enable this on my phone, and what's that passphrase the tool alludes to? I don't see an option to set one in the Android app.

Yes it's custom-built by Signal. I thought it was enabled by default — I don't remember ever turning it on — but it might not be. Here is how to do it:

> Where can I find the backup file?

> Your backup folder is listed under Signal Settings profile_avatar.png > Chats > Chat backups > Backup folder. Use the files app or plug your phone into a computer to go to the folder.

> For older versions of Signal, the backup file signal-year-month-date-time.backup can be found at /Internal Storage/Signal/Backups or /sdcard/Signal/Backups

Huh, then I have no idea what they are doing with backups anymore. It makes zero sense to support that on Android but not iOS.
