From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I use immutable nixos installs. Everything to redeploy my OS is tracked in git including most app configurations. The one exception are some GUI apps I'd have to do manually on reinstall.
I have a persistence volume for things like:
I have 30 days (or last 5 minimum) of system rollbacks using BTRFS volumes.
The personal files are backed up hourly to a local server which then backs up nightly to B2 Backblaze using rclone in an encrypted volume using my private keys. The local server has a mishmash of drives in a mirrored LVM setup. While it works well for having mixed drives, I'll warn I haven't had a drive failure yet so I'm not sure the difficulty of replacing a drive.
My phone uses the same flow with RoundSync (rclone + GUI).
Git repos are backed up in git.
Logs aren't backed up. I just persist them for debugging and don't want them lost after every reboot.
Caches/Games are persisted but not backed up. Nixos uses symlinks and BTRFS to be immutable. That paradigm doesn't work well for this case. The one exception is a couple game folders are part of my personal files. WoW plugin folder, EvE online layouts, etc.
I used to use Dropbox (with rclone to encrypt). It was $20/mo for 2Tb. It is cheaper on paper. I don't backup nearly that much. Backblaze started at $1/mo for what I use. I'm now up to $2/mo. It will be a few years before I need to clean up my backups for cost reasons.
The local server is a PC in a case with 8 drive bays plus some NVME drives for fast storage. It has a couple older drives and for the last couple years I typically buy a pair of drives on sale (black Friday, prime day, etc). I have a little over 30TB mirrored, so slightly over 60TB in total. NVME is not counted in that. One NVME is for the system, the others are a caching layer (monero node) or temp storage (transcoding as it also my media server).
I like the case, but if I were to do it again, I'd probably get a rack mountable case.
You seem pretty organized in your strategy, I would suggest you just pull a drive in your LVM to check how that goes for you. I've had issues in JBOD style LVM volumes with drive swaps, but YMMV.
Frankly, I use ZFS now in anything that I would have use LVM in before. The feature set is way more robust. Also, an offsite ZFS replication to zfs.rent is a good backup of a backup. But Backblaze is pretty solid too.
Good call on a simulated failure. When I first set it up, it was LVM/BTRFS or ZFS as my top choices. It was a coin toss at the time because I hadn't built this sort of setup before.
Yah, an untested raid is like an untested backup: suspect.
Hetzner's storage boxes have caught my eye but i haven't tried them yet.
