Nextcloud for me. I run my own home server, which is just a normal PC on a cheap UPS, on a residential internet connection with dynamic DNS. On that, Proxmox, and Nextcloud lives in there as an LXC container.

On my phone, the Nextcloud app is installed, and that takes care of the photo/video/downloaded file "cloud" sync, and DAVx5 takes care of calendar, contacts, todo. Nextcloud, with additional apps, can also do Kanban, multimedia notes.

I don't have root on my android and I try to avoid using any FAANG's infrastructure. A few weeks ago I bricked my phone and lost a bunch of data because I only backed up my photos. More on that in a sec, but the big thing I learned is how much stuff on my phone I didn't miss once it was gone and how much I did miss. App backup? who cares? This was a chance for me to see what's new on F-Droid and it's been great (look…

Stop using F-droid. It is insecure and shouldn't be the primary way of installing apps. Stick to Aurora Store or Play Store

I read your sources, and one, as a user, I'll let these people sort out their drama among themselves, two, the security issues of the apps that are downloaded I think are way higher potentially than the ones in F-Droid in itself. With these considerations, F-droid is fine as a way of installing apps. Just as fine as any other technically imperfect service, business, or product that we use daily. In fact, I consider it higher than average in quality.

Important to note: unless backups are implemented on the nextcloud server itself, this is sync, not backup.

Earlier quoted context omitted.

I just restored my backups a few weeks ago when I bought a new phone. It doesn't work for all apps (I knew it, it's far from the first time I do that) but I am satisfied with the results. It does help sometimes for retrieving some data manually by digging through the backup files (used it recently for retrieving all invoices from a service that were otherwise only available one by one through a painfully complicated…

My use case would be to get my WhatsApp database…. Anyone knows if it restores properly? (Useful even if not … WhatsApp search is abysmal, the db file is much more useful)

Not sure if it restores well because I don't use WhatsApp anymore, but I checked in an old backup and somewhere in the files there's an SQLite3 database "msgstore.db" with a "messages" tables that contains messages.

You don't. Google backup is partial and very limited compared to what apple does, plus privacy issues and you don't get access to app folder without root. (I know about adb but then you can't push the files back there). So it's a shitshow as usual with Android, it all depends on the app. My weight lifting app it can backup on Google cloud. Great. My 2Fa on the other hand it only backup to the 'external' storage, need…

Last time I had an Apple device the only way to backup was plugging it into a desktop with iTunes. How do you figure Google's backup (which backs up contacts, messages, photos, mail, and remembers which apps you have installed) is bad? What more could it do or should it do in your opinion? Also Google Authenticator now backs up to your account and you can recover it through a logged in browser.

It uses Google. I have servers, desktops, laptops and phones, all of which are computers and all of which are on a local network. It should be possible for me to move all the data on my phone to a server, desktop, laptop or other phone without once sending a single byte outside of my network.

I've never used Android, so the answers here are surprising. There's really no equivalent to iTunes/Finder that'll just back up your phone to a PC?

This is partly because Android apps may store data in one of several locations.

In previous versions of Android it was possible for apps to store data in an arbitrary folder on the device (if the user granted the relevant permission).

That resulted in it being quite difficult for the OS to identify which files and folders related to any single app.

In more modern versions of Android, most apps are no longer allowed to write wherever they want, and are encouraged to only store data in a private folder (like iOS).

A backup system is now present that can back things up in a manner to iOS, but it's limited to 25MB per app, and some apps opt out:

I see your point, but from the perspective of the Android phone, this is already a backup. This is because if I lose the phone, I can restore the important parts of its state from the copy on the server - which is the definition of a backup, according to Wikipedia for example.

Now, of course, we can look at more stringent approaches to backing up data, which I already do, but for some reason I didn't elaborate on the original comment. My home server uses ZFS as storage, and I snapshot that from time to time, and I sync those snapshots to another, otherwise offline ZFS storage. The true 3-2-1 I still don't achieve, because both the online and the offline copies are at the same site, but I opted to take this risk.
