Just one would be a great backup, but I’m not ready to run a server with 30TB drives.

[–] mosiacmango@lemm.ee 9 points 22 hours ago (1 children)

I'm here for it. The 8 disc server is normally a great form factor for size, data density and redundancy with raid6/raidz2.

This would net around 180TB in that form factor. Thats would go a long way for a long while.

[–] Badabinski@kbin.earth 7 points 22 hours ago (3 children)

I dunno if you would want to run raidz2 with disks this large. The resilver times would be absolutely bazonkers, I think. I have 24 TB drives in my server and run mirrored vdevs because the chances of one of those drives failing during a raidz2 resilver is just too high. I can't imagine what it'd be like with 30 TB disks.

[–] killabeezio@lemm.ee 2 points 15 hours ago

Yeah I agree. I just got 20tb in mine. Decided to just z2, which in my case should be fine. But was contemplating the same thing. Going to have to start doing z2 with 3 drives in each vdev lol.

Is RAID2 ever the right choice? Honestly, I don't touch anything outside of 0, 1, 5, 6, and 10.

Edit: missed the z, my bad. I don't use ZFS and just skipped over it.

A few years ago I had a 12 disk RAID6 array and the power distributor (the bit between the redundant PSUs and the rest of the system) went and took 5 drives with them, lost everything on there. Backup is absolutely essential but if you can't do that for some reason at least use RAID1 where you only lose part of your data if you lose more than 2 drives.

How can someone without programming skills make a cloud server at home for cheap?

Debian, virtualmin, podman with cockpit, install these on any cheap used pc you find, after initial setup all other is gui managed

[–] frezik@midwest.social 4 points 20 hours ago

Raspberry Pi or an old office PC are the usual methods. It's not so much programming as Linux sysadmin skills.

Beyond that, you might consider OwnCloud for an app-like experience, or just Samba if all you want is local network files.

I run docker services and host virtual machines from Unraid OS

Here i am still rocking 6TB.

[+] NuXCOM_90Percent@lemmy.zip -13 points 22 hours ago (9 children)

Just a reminder: These massive drives are really more a "budget" version of a proper tape backup system. The fundamental physics of a spinning disc mean that these aren't a good solution for rapid seeking of specific sectors to read and write and so forth.

So a decent choice for the big machine you backup all your VMs to in a corporate environment. Not a great solution for all the anime you totally legally obtained on Yahoo.

Not sure if the general advice has changed, but you are still looking for a sweet spot in the 8-12 TB range for a home NAS where you expect to regularly access and update a large number of small files rather than a few massive ones.

[–] barkingspiders@infosec.pub 4 points 18 hours ago (3 children)

honestly curious, why the hell was this downvoted? I work in this space and I thought this was still the generally accepted advice?

[–] NuXCOM_90Percent@lemmy.zip 3 points 17 hours ago (1 children)

Because people are thinking through specific niche use cases coupled with "Well it works for me and I never do anything 'wrong'".

I'll definitely admit that I made the mistake of trying to have a bit of fun when talking about something that triggers the dunning kruger effect. But people SHOULD be aware of how different use patterns impacts performance, how that performance impacts users, and generally how different use patterns impact wear and tear of the drive.

[–] Blue_Morpho@lemmy.world 0 points 14 hours ago

Come on man, everything, and mean everything you said is wrong.

Budget tape backup?

No, you can't even begin to compare drives to tape. They're completely different use cases. A hard drive can contain a backup but it's not physically robust to be unplugged, rotated off site , and put into long term storage like tape. You might as well say a Honda Accord is a budget Semi tractor trailer.

Then you specifically called out personal downloads of anime as a bad use case. That's absolutely wrong in all cases.

It is absurd to imply that everyone else except for you is less knowledgeable and using a niche case except you.

So I'm guessing you don't really know what you're talking about.

[–] Gradually_Adjusting@lemmy.world 5 points 22 hours ago (1 children)

Oh hey, I did something right. That's kinda neat

I am troubled in my heart. I would not have been told so in this way.
