adb backup

If you control the build, you should implement your own Backup Service. You should not just open all apps' data to any app.

Oh, that useless thing. I was very confused about something which can "app data that requires authorization" (thought maybe it's some Google service that extracts your secrets for device migrations) but you just mean the old adb backup that the security industry (that I'm part of, and fighting from within :p) destroyed in the name of people's own good

Like, yes this exists, but it doesn't back up half the things you need :(

"adb backup" is buggy and deprecated.

It's easier and more reliable to use adb root to rsync everything. No apps need root access that way.
