I'm in the same boat. I don't have a physical backup in the form of an external hard drive or a backup server, so this question made me stop and think for a second why I don't. But I really don't have anything I can't replace that isn't stored in the cloud.

That's what I use for backups of my business accounting software, but I'm seriously considering changing since losing some sales tax files from Drive. It never really dawned on me that three months worth of records could just vanish, but they did. Thankfully I had paper copies and was able to recreate the spreadsheets, but it was quite a bit of work.
I'm assuming you use Bitbucket for free private repos and GitHub for free public repos? If so, I used to do the same, now I'm just using GitLab since it has free public and private repos.

I use a raspberry pi 1 with a 1TB USB HDD as a "backup server", it used to live off-site in a friend's basement, now I have to find a better place for it than my desk. Having my Nextcloud, PC, laptop and backups all in one flat is not a very comfortable thought.

it doesn't have any out-of-band management. If it dies or you shut it down, someone needs to unplug it and plug it back in.
As long as it's not lying around in some datacenter though, it's just fine.

This is what I use. I'm a professional video editor and so my back-ups are huge and I can't really use a cloud service for it.

Squashfs. It's a usually builtin filesystem for Linux (what I use everyday) that is read-only, and supports some pretty decent compression (usually about 36% of the size for me, but experiences differ, it uses zlib under the covers).
My laptop compiles all my documents and important information into a squashfs file every ten minutes or so. Then, when I connect my laptop up to an external drive, those backups are immediately stored on it (edit here. Multiple backups, not singular).
You can also mount your backup without fear of breaking it, so you can go fishing for old files.
Squashfs also allows you to test integrity, and bit-to-bit comparisons rather easily, to ensure you can still restore from backup.
Speaking of restore, it's a simple dd command (run probably from a live disc), and I have my drive back in a known working order.

I'll second Synology. I have a 4-bay DS918+ with 2x8 TB and 2x2 TB, single redundancy. The 2x8 hosts all my raw media files and other housekeeping type stuff, then the 2x2 TB is split between time machine backups, surveillance station backups, and DS Photo syncs.

For file duplication I use Syncthing:
Syncthing is installed on all devices
Folders are synced between desktops, laptop, (android) phones
Some folders are "masters", meaning that it doesn't accepts changes made by the other side
A "central" desktop keeps a copy of all important folders from each device
Syncthing is configured to keep deleted files for XXX days
Syncing only happens when devices are connected to my local network (using ethernet or wifi)
Now, this is not a proper backup. If a file is modified, it replaces the original file on the other side too, but if my phone goes for a swim, I have at least two copies on two different places.
I only have around 150GB of data that I consider to be really important. I make a monthly encrypted backup to an external drive and to Backblaze B2.
I already have two local (raid) copies of media content (again, using Syncthing), but from time to time I also do a manual backup to an external disk. I only have around 1TB of this stuff and I could always download everything again if something destroys my house.
I could improve this setup with real time backup by using something like Google Drive, Dropbox, etc, but for my usage it's not something I really need.
tl;dr:
Syncthing to sync content between devices;
Important stuff is backed up every month to an external drive and cloud;
Media content on two raid machines, manual backup to external drive every 3 months or so;
Not perfect, but I've been using this for 3-4 years and never had any issues.
I had a go using Syncthing a few years ago. I got it working but it wasn't straightforward and some stuff refused to sync. Keep meaning to give it another go. I guess it's much better now?

I used to use HDDs but then I was lazy a just back everything up. Now I'm having to look back over it and it's the most frustrating thing imaginable.

I don't need a backup of my a game or software instalation nor do I need a downloaded folder with is full of just drivers and random crap.

Duplicacy (the free and open source command line version — there's also a paid GUI) backing up to a Google Drive business account. $10/m for unlimited storage.
Arq is old-fashioned paid software. It's about $50 and works with a number of cloud providers, if you're into that. I like Arq, but I've had a couple of issues related to it being, I believe, a one-person operation. Once they announced that there was a major bug in the garbage collection process that might delete data that you still need. More recently I ran into a bug where canceling a restore midway through can leave partial files on disk which it won't try to overwrite the next time you back up. I'm considering Duplicacy as an alternative.
Duplicacy has been super solid, just uses a lot of memory during multi-TB backups. I've hit funny issues with Google Drive, too. One of my chunks got marked as malware and I had to patch Duplicacy to send the right API parameter to ignore that. Another time, one of my chunks just couldn't be downloaded and then suddenly could be a few days later.

The poor security is definitely worrisome but in my case it's a non issue. My main goal for backing up files is to make sure family photos are backed up off site somewhere. Although it wouldn't be good if the files were somehow compromised there's really nothing there that would be problematic for me.
Financial documents and other sensitive documents are stored in seperate encrypted containers on my machine for piece of mind. My assumption is that these types of files are just as much at risk on my computer as they would be somewhere else. For things that I want to have an extra layer of security I use this method.
Does it work for me? Yes. Will it work for others? Maybe. Is it an excellent option? No but it's good enough for my case. Is the price right? Very much.
Edit: By the way if you have any suggestions that are user friendly and cheap that are better than Backblaze's offering, I'm all ears.

I should clarify that the financial documents and other sensitive documents are not stored unencrypted on the harddrive and the encrypted containers are what get backed up. I don't just keep them on my machine but, I also don't put my faith in them being kept secure by backblaze's security measures.
Even if there is a breach on their end and the encrypted containers get out somehow, at least there is a good layer of protection on them. On my machine I mount and access the files as needed but they aren't needed frequently so it ends up being a good system for me.

I have a recovery disk of my Windows system in case it needs restoring, and I back up sensitive files on an external hard drive that I keep in a high-security vault (also known as "the bottom of an IKEA storage box filled with unused cables and other computer hardware). Most everything i have on my devices I don't really care if I lose or not. Nothing is really unique or important enough for that to matter.
External HDDs primarily, though I also like to copy smaller documents on to memory sticks for easier access. I tend to have multiple local backups as they make the most sense to me.

Very little of my data is meaningful to me. I keep a few local copies on every hard drive just because they're so small. I probably have some copies around on USB sticks or Google drive as well but it's not something that I regularly bother with.
Hell even if I lost all of my data and backups it really wouldn't cause me any issues, at most I lose a couple of funny pics that I look at once a year when I decide to poke around some old folders, and then forget about until next time.

The RPi idea is interesting! Right now I'm just using an HDD for backup and it isn't off-site.
Off-site backup once saved me in the aftermath of a very nasty theft. Things have changed since then and I ought to find a way to do it again.
Yeah, it's a nice and cheap solution for DIY off-site backups. The only problems I have with it:
pacman -Syumeans 10-30 minutes of lock-upAs long as it's not lying around in some datacenter though, it's just fine.
Actually, the Pi has a watchdog timer. You can use that to reboot the Pi if it gets locked up for too long.
Huh, yeah, that's true. Gotta take a closer look at that when I've got time. An alternative would be to craft something out of a microcontroller with network connection that just drives the pi's GPIO and serial pins, then you'd even have console access.

Squashfs. It's a usually builtin filesystem for Linux (what I use everyday) that is read-only, and supports some pretty decent compression (usually about 36% of the size for me, but experiences differ, it uses zlib under the covers).

Multiple HDDs locally for important files like photography, etc.
Very little of my data is meaningful to me. I keep a few local copies on every hard drive just because they're so small. I probably have some copies around on USB sticks or Google drive as well but it's not something that I regularly bother with.
Hell even if I lost all of my data and backups it really wouldn't cause me any issues, at most I lose a couple of funny pics that I look at once a year when I decide to poke around some old folders, and then forget about until next time.
Syncthing to distribute often accessed files over all devices where I need them in a pseudo backup fashion.
A local copy on a btrfs multi-device array.
restic in combination with rclone to dump all other stuff I need backed up but don't need to access on many devices or regularly on mega.nz actually.
For important, mostly administrative, files I use Google Drive. Though I've been thinking of a non-cloud reliant solution I'm a little worried that the risk of failure of such a solution outweighs the risk of a cloud data breach.
On my mac I'm using backblaze, which I've found to be a pretty good service. I'd love to use it on my PC if only they had a linux client :(
