Welcome here @LoftyGoals !
I do NOT backup my laptop, my phone or my desktop. Instead I do this:
- I use Syncthing to keep the files I care about synched between my devices and my NAS.
- I run Restic on my NAS for backup.
The benefits I see are these:
- The files are available where I need them regardless of which device I am using at the moment.
- I don’t have to use VPN between my “portable” devices and the NAS.
- I need to backup only ONE device: The NAS.
