I use adb and a script to pull my data via USB. Backup and restore is easy. Unfortunately, this is largely useless to me. The actual data on my phone already easily syncs as needed as part of the apps I use. What I really care to back up is the app settings and account data, which I haven't been able to successfully transfer. When wiping or changing phones, reconfiguring and logging in to all my ~100 apps is tedious to say the least, even with a password manager. If anyone has a non-google-services, non-root solution to that, I would love to know about it. Convenience and difficulty don't matter, anything can be scripted.
