I know that making networks out of duct tape and bubblegum is a point of pride in the Linux community, but if you have to store vital data, wouldn't a nice hardware NAS and a RAID array be a better solution?

Funny. My WD nas runs linux and the support ended so i've had to upgrade myself with entware... and it's old, so the fan was sized for cooler hard drives, so I cut a hole in the top and screwed on another fan... and WD removed NFS support years ago, so I just mount my shares oversshfs... and i'm currently upping my local security so it's only accessible over wireguard... honestly, I have no idea what it's doing with the hardware raid and the way it mounts drives so i'm tempted to switch over to mergerfs and snapraid...
Basically my legit consumer hardware raid nas is more duct tape and bubblegum than my home built linux nas. Then again, it's easily a decade past its anticipated useful life too.
I guess it is a point of pride.
Backups people backups. You don't realize how much you want them until it's too late to make them.
don't worry I have raid, that's a backup right?
Raid 0 right? I heard the number stands for how much risk there is of losing data.
Add more disks for more reliability
Due to the green economy I only buy second or third hand disks for my RAID0 setup
Also remember to backup before things break. I once diligently backed up a system image before an upgrade. But I backed up a already failed SD card.
and if possible, keep some backups in a separate physical location. House fires or break-ins aren't all that uncommon.
A good advice, but most regular people don't seem to bother with rotating physical off-site storage mediums so I advocate automated (and encrypted) backups to a cloud or something as well.
LPT: pies since at least the 3b can boot from USB.
If you must use an SD card: use log2ram. Greatly reduces the number of IO operations to the card and prolongs its life.
I’ve never relayed to a meme more. I moved my UPS to my work computer after that one failed and three days later, I lost power. Spent five hours fixing a corrupted SD card then reconfiguring my Pi-Hole and HomeBridge.
Pfft, mine boots from a USB SSD, and since my services are all containerized I just gzip the directory with all my docker-compose files and volumes and chuck it into B2 every 6 hours
M.2 sata to usb enclosure
I just bought this, we'll see how easy it is to setup. Do you still run raspian on it, or something else?
Very easy. https://www.makeuseof.com/boot-raspberry-pi-4-via-ssd-network/
I used to run Fedora, now openSUSE on mine.
do you use a separate power for the sad? or just leave it plugged into the raspi?
No, it's a NVMe to USB-C enclosure, with a USB-A to C cable connecting it to the Pi. No external power.
I run ubuntu server on my RPi 4 with USB3 SSD. No issues so far, but needs a good PSU. Survived a blackout without an issue.

This has happened several times to my Pi-Hole. Even with backups, trying to get my network back online still takes too long. I haven't found a good solution for resilience yet.
Try to use overlayfs under raspi-config, I've been running some raspberry pis for years with that (mostly on offsite locations where fixing dead sd cards is not possible)
Updating the pis is a little more work but in some use cases it's worth it
Honestly something that critical probably shouldn't run on a rpi. There are plenty of cheap used thin clients you can buy on eBay that have better performance and reliability. I probably like the thinkcentre micros, but feel and hp have good options too
Pis can be supremely reliable when used correctly for the purpose. E.g. use high quality SD cards and don't write to them much, or a good quality SSD if you have to do significant writes, etc. My oldest 4 is from 2019 and it's been in continuous use since then. It used to be a NAS running a 2-disk mirror exported over NFS. These days it's a gigabit OpenWrt router with SQM. It's still in the original SD card.
Full redundant JBOD backup. It's unfancy and safe.
My phones sd card died this weekend. Fuuck. Still trying to recover the data somehow. Can relate..
SD card clone taped on the box, USB disks and ZFS. Mirror works well. You could try a 3-4 disk RAIDz1 through a USzb hub if you're feeling ambitious.
Why are 5v ups's not a common thing?
They are, kinda. You can buy a power bank that can be charged and still output energy
They are? ~~Hours~~how do I look for one? Never seen one that could do that, mine certainly doesn't.
Some models support it. I had one from PowerAdd
Is it advertised somehow?
I saw it in a review, so idk
Not quite the same, but I made the mistake of using my RPi to run my home server and NAS off of an external USB non-NAS (i.e., not intended to be running 24/7) drive...with no backup or redundancy. The drive actually lasted a good long while, but it did die, and very suddenly, a couple of months ago. And now I've lost all my stuff that was on it. Still holding out hope I can figure out a way to recover the drive, but yeah.
Back up your shit, yo.
Is it an HDD? Those are quite easy to recover, just put the disk into a working HDD
Sorry I'm not sure what you mean. Yes it's an HDD. A USB plug-in one in a non-user-serviceable enclosure. I can't (without completely destroying it) get the HDD itself out. And I'm not sure what it would even mean to put it into a working HDD. The broken HDD itself is the problem, I think.
this is what I mean by putting it into a working hdd
what model is the usb dongle?
I can't recall the exact model, but it's some form of Seagate Expansion Desktop, sort of like the ones shown here. Mine was 1.5 TB, IIRC.
Thanks for that link. Wish there was a bot to translate links back into normal YouTube videos like there's one to send you off to that other site, but it's easy enough to manually change the URL I suppose. Anyway, doing that is way beyond my skills, and I'm not sure the data would be worth paying a professional to do that either. I can't imagine that comes cheap.
Opening a HDD on your own is usually a terrible idea.
HDDs need a completely dust free environment so that no dust enter the harddrive.
I would recomend something more repairable in future, sorry for your data loss
