In some regions, afaik, you just CANNOT install certain apps without adb, this in my experience includes: KDEConnect, Fdroid, Newpipe...etc. The list changes time to time.
I honestly think that this is just not going to happen. It's already a giant pain in the ass to install apps from anywhere else than Play Store. With Shizuku it got much, much better.
You'd be kicked out of highschool debate at this point, but okay.
Did you actually read what I said? Jesus being a real historic person and not being a son of the God or whatever Christians believe him to be is not mutually exclusive.
This is not the way to be critical about Christianity(or anything, really). If anything, you're making it worse.
Exactly what are you trying to back up? If it's for something like, let's say, a password manager, syncing is the worst way imaginable.
But if it's for your Jellyfin media backup, rsync is pretty sufficient imo. They rarely change, costs pretty penny to back up and (relatively) easy to rebuild.
Linkwarden has pretty minimal hardware requirements - it was tested on a VPS with 4gb of memory and it ran pretty smoothly, the most intense part is when you build the app, but once it's running it's relatively lightweight.
From their website. I wouldn't consider tested on 4gb vps having minimal hardware.
I use Linkding and I am very happy with it. Less feature? Maybe. But it's a bookmark sync. What do you need?
Or just block internet access completely.
