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?
SMBSync2. It looks sketchy as hell but has a pretty intuitive interface to copy files to a NAS.
First create a task saying which folder to copy to where. Then either activate it manually or put it on a schedule. It makes it possible to auto create new folders based on date whenever I do a copy which I love.
