Someone recently told me about a RAID configuration that can mitigate bit rot but it was a long conversation and I forgot a lot of what they said. I'm currently in the planning stages of setting up my first NAS so if anybody could point me in the right direction that would be pretty sweet.
What the hell is RAID and NAS ? I have a bad ass DvD collection to the tune of 3k films ( no pineapple express bull shit ) that I've been wanting to back up. I don't know shit about computers but have a 2014 MacBook pro with a disk drive that has never been online just used to watch movies when the power is out and to load my cd collection to mp3 players.
Help me out here !!!

ZFS has bit rot protection.
I am currently buying hardware for building my first NAS.
For inspiration, this is what I am building:
Case: White Jonsbo N4
CPU: Ryzen 4600G
RAM: Corsair Vengence 32GB DDR4 3600mhz
Boot drive: Crucial T500 500GB nvme drive.
Storage drives: Seagate Ironwolf Pro NT (I have not yet decided of what capacity I will use).
PSU: Corsair SF750 (overkill, I know) -

NAS stands for "Network Attached Storage", basically a computer whose sole purpose is storing and serving files in your home.
RAID stands for "Reduntant Array of Inexpensive Disks", and is broadly a way to merge multiple disks into one.
RAID 0 means that files are evenly distributed on all disks, which improves IO speed and extends a file system (≈ a partition) 's capacity, but it's useless against disk failure;
RAID 1(mirroring) means that all disks have the same data as a sort of real-time backup, and as long as one disk remains functional, all the other disks can fail without the data becoming inaccessible;
other RAID levels use clever math to offer a mix of the first two, spreading files among disks (like RAID 0) but still tolerating failures of a small number of disks (like RAID 1 but way less redundant).Wikipedia has a less abridged explaination on its RAID page.

A RAID is essentially a way to have multiple "hard drives" connected in a way that looks as if it's one drive so you can have a ton of storage.
A NAS is a sort of like a remote storage device. Not quite a PC, but more than just a storage drive.
Not sure how you'd go about doing any of that with a MacBook.

flash storage too! idk the specifics but I think flash storage has a lifespan of around 15 years
in practice; go backup old flash drives and game cartridges (ex: DS and 3DS cards)

wrote on last edited by [email protected]Adding to that, depending on your RAID configuration you can have one or more drives fail and not lose any data.
Also you can install things like Plex media server or Immich and set up basically your own equivalent of Netflix server or google photos and look at your media from pretty much anywhere.

What's a good medium to back up to, assuming I don't want to pay for a RAID setup?
-
To be fair, RAID is not backup for itself but if they have their stuff on a computer and then sync it to a NAS RAID then that's backup.

So glad that I don't have much important data, a very simple bash script backs up stuff that kinda matters (do I need that 8 year old minecraft save?) and it totals about 30GB currently.
The actually important bit is a 57kB Keepass database. Plus 50MB of compressed/encrypted data of questionable importance - literally never decrypted them other than to test it was readable, but I have been told these documents are "important" so whatever. They are there and the originals burned because I don't want to keep a shitload of paperwork around that looks worthless to me. Got a small folder for stuff that probably should be kept like birth certificates, when that folder gets full I sort and the least important stuff is recorded digitally and physical copies destroyed.

Yeah, the idea is that you should have another copy that is disconnected from the main one, if you have that then you do have a backup.

I have 5-1/4" floppies from the mid 80's that still work.

PSU: Corsair SF750 (overkill, I know)A piece of advice with ZFS, get the largest drives you can afford.
Expanding ZFS is painful and it's wayyyyy easier to just start big then to grow big.
ZFS is also a RAM hog, max out your ram cause that.
If you want to add meta data caches, do it when you first build the array.
The L2-arc cache and SLOG don't do what you think they will. Make sure you really understand them before you throw them on. They're easy to take off though.
Last but certainly not least, ZFS is a money sink. It was made for enterprise solutions, meaning it benefits from more money being thrown at it than say XFS. Figure out what's good enough and live with it.

PSU: Corsair SF750 (overkill, I know)wrote on last edited by [email protected]I switched to raid z2 from a 6 drive mirror and what an ordeal that was. It's because I had to grow into it and buy drives over time but eventually the mirror was too inefficient.
I moved data around like 5 times all because I still didn't have enough disks to build my new array and keep my data on the system at the same time. And expanding raidz expands parity on all disks but not the data so you have to recopy all your data so it stripes fully.
I had a backup on a DAS but USB is slow and I didn't want to have it be the only copy.
Edit: clarifying my point. I have no regrets. ZFS is awesome. But make the important decisions up front and yes start with the right amount of drives that you need. My whole issue was growing into it and having to make changes after the fact.

I plan on having a raid of 5 drives and a hot spare, with a cold spare next to the NAS.
I am considering 8/10 TB drives, I currently have less than 10 TB of data in my archive.
What are the advantages of the different raid z leves?

Media store is a 12TB and an 8TB that dump into a 20TB that sits cold all but once a month.
My more immediate data that I need day to day is in a synced Documents folder across four different devices. I don't back it up, per se, I just make it impossible to lose.

That is a fair point, earlier I considered OpenMediaVault with a softraid and an LVM on top if it, but I take a lot of photos and have already seen bitrot in them, so I'd rather have some insurance for that.
I will in general avoid expanding filesystems, and simply decide that when I need more space to start building a new NAS, copy the data to it and repurpose the old NAS with larger drives or as a test machine.
Though this depends on how financially stable I am, I tend to buy parts over time...

Genuine question, do people actually care about backing up media that much? I don't get it. Everything I actually care about personally I can fit on a thumbdrive and a box of notebooks.

I consider most data on my devices as replaceable, I would only back any of it up if the effort to replace it was much harder than the effort to back it up.
