I use rsync normally but I want something similar for my Android (GrapheneOS) smartphone. I want to just click and backup everything that I set up earlier. For now I manually copy folders to one and then upload it to external drive. What are your recommendations?
Generally I don’t keep important stuff on my phone. That stuff is in cloud storage and synced down to my phone as necessary.
Personally I use Google Drive, but you could certainly self-host an equivalent.
