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?
I use Resilio to constantly back up everything to my NAS, then I run a backup nightly to iDrive e2 from there.
Resilio monitors the folder(s) you pick for new files and instantly uploads them. I have it set to the root at /emulated/0 so it just grabs everything.
