Archival Computer Storage

Which storage medium does Jow Forums use to archive REALLY important computer data?

tape drives

Cold storage, slow but large storage Hard Drives.
I wanna look at tape drives though, much cheaper

the ultimate storage medium

based

i love tapes, but i would argue that tape cartridges are more optimized for data backup, rather than data archiving. they are extremely cheap per GB (after the huge initial investment for the drive), they are very dense, and they arent optimized for speed. however, due to ferromagnetic depolarization, they only last about 5-10 years before data-rot kicks in. a good archival storage medium would primarily focus on longevity, rather than data density or even cost per GB.
>much cheaper
yes, but only after you purchase the super expensive tape drive.

You did encrypted that data, did you?

yeah but worth for the exponential shit tons of storage i get after

>optimized for data backup rather than data archiving
>they aren't optimized for speed
if you're archiving data you don't need speed.
tape drives lasts around 30-40 years
unless you're keeping them on your croch spitting pieces of food and cum on them

Nice English

its the tape itself. the data integrity will drop drastically if not kept in good condition. you also have to regularly check the data - if you start losing anything, better start moving it onto new tape

Imma try this when I get a laser engraver.

for really important stuff i create copies on multiple different storage mediums for redundancy. m-discs, hdds kn server, ssds in main machine.

>if you're archiving data you don't need speed.
i know, that was my point.

thank you
then keep it in good conditions

Archival Discs
300GiB per disc.

M-DISC since they will apparently last 1000 years and have rally good environmental tolerances.
My uni uses them for backups in some cases.

>Cold storage, slow but large storage Hard Drives
That's as retarded as it gets, enjoy your seized bearings

bluray, got $50 chink usb drive and 100 pcs disks during some sale locally.

Was thinking about LTO5 but those things are complex, in decade or two who knows hows hard it'll be to get one in working order.

Among other things, HDD in [your own] storage cloud.

What this gives you is very frequent verification that the data and its design redundancy is still completely intact and accessible.

Do secondary backups on tape and/or discs, the earlier very easily tie into data clouds too.

I don't, I lost my bitcoin wallet due to lazyness.
Also I think the harddrive I'm using rn has problems and may fail soon and I still haven't backed up my photographs

please please please buy another HDD at least
they're so ridiculously cheap now.
4TB for £80 on amazon. why not?

I would store the data on multiple mediums, depending on the amount of data. With data that is really important, I would even go as far as creating physical representations of them, such as printing out on plain white paper (base64 or whatever your preferred encoding).

Redundancy is key.

I like the paper idea, OCR is really good nowadays so it'd be easy to scan it and recreate it
you're a fuckin genius desu

Forgot to mention, if your really paranoid, you could even store that data in a safe deposit box (in a bank or underground vault). They aren't really expensive either.

It'll feel a *whole lot* less genius if you want to scan in even one 10TB drive worth of data on paper (which you sensibly encoded with some redundancy against loss of a bunch of pages, making the stack even 10-30% or so larger).

buy a professional scanner which goes through large stacks :^)
but yeah thats a shit ton of paper

I never tried it but theoretically, it should be really easy to do as we have tesseract and other really good open source OCRs.
As a matter of fact, I might try it one of these days and if I like it enough, I might even write a program to simplify backing up stuff on paper. I'll post it here on Jow Forums and release it under a foss license if I decide to go with it.

>In the (((bank)))
Might as well just upload it to Google drive.

I was just thinking of doing that!
automation would make it very little effort other than buying ink and paper.

It's obviously not for large quantities of data, but I'll give it a shot to see how much data can be packed on 1 piece of A4 paper while still being readable by OCR.

Yes, and a scanner that can reliably process these stacks might cost you more than keeping 100TB at 5x redundancy online for the rest of your life might have cost you.

And then you find out you also need to hire a programmer because the exotic backup-to-paper software you used has been discontinued 20 years ago and you need to update it to even use it.

(((ink cartridges)))

Do saphires you fool

i don't have any data important enough for that.

I back all my university work up on a free onedrive, and then across 2 HDDs on my NAS that copies from the main drive to the second every week with the rsync command.

no pointless raids, and an offsite backup. works for me

>implying I'm falling for the ink scam

I got a HP FS-1028 MFP laser printer used for around 30 euros. The toner cartridges cost around 10 euros a piece, they can print up to 54k pages. I haven't bought a toner cartridge since I got the printer around 4 years ago and it's still going strong.

where are you getting the toner so cheap?

>yes, but only after you purchase the super expensive tape drive.
I bought a LTO-2 drive (brand new) plus 1TB of tapes for less than one spindle of 4x 25GB M-DISC. I can just write multiple copies if I'm worried about one failing. M-DISC also has the risk of ruining a disc due to a bad burn whilst tape can be re-written to over and over.

i would cry. cry a lot.

big brain play incoming
create a tgz archive of all your important shit
encrypt the archive with gpg
use the GNU/Linux "split" command to split the encrypted archive into 4.7 GB chunks
burn said chunks onto mdisk archival dvds

very big brain desu

A few mirrored HDDs that I swap out every month or so. I keep the spare in a safe.

you swap them every few months?? thats a lot. how come? why not yearly or something

The only files I truly want to preserve are pictures of pets (especially my dog who died in 2016) which I copy to every drive I own, plus a few CDs, and the best ones have been printed.

correction: Kyocera FS-1028 MFP and 7.2k pages
goes to show that I didn't buy toners in forever kek.

You just don't buy the printer manufacturers toners, as they usually have higher markup than "compatible" toners. I just did a quick search on google and found a unit for 10 €, 15 € with shipping.

i, like god, use tablets

I see you're a man of culture as well

It's not just static files. I'm always adding new photos, new code, new financial records, stuff like that.

My brain

first 2000 digits of pi. now.

Hard drives, because having automatic regular verification of data and swapping them out when they fail or show signs of failure is better than tape garbage where you don't even know if it's fucked until you try to restore. Can only be read a few dozen times as well and the tape drive can be a single point is failure if they won't read correctly on a different one, unlike hard drives which will work on any computer. Only advantage of tape is that it's still cheaper, but not by much and not for long. Just get another offsite hard drive backup instead of wasting money on tape.

Error: Comment too long

backups and archives are different. the purpose of a backup is to prevent the loss of data that is currently in use. backups require a medium of storage that is dense, cheap per GB, and does not necessarily require speed. tapes are really good at this.
the purpose of data archiving, on the other hand, is to create and maintain a repository for data currently NOT in use. this data may need to be stored for periods that extend from months to decades. data archives require a medium of storage that is, above all else, able to last a really long time. data density and low cost per GB is just an added bonus. i would argue that optical media is the best when archiving important information, as it is not subject to ferromagnetic depolarization that magnetic media is. due to this depolarization, the longest you could expect a magnetic storage medium to retain your data is between 5-10 years before the data begins to rot and corrupt.

Good idea!!!
Lemme just stainlessteelpunchcard all my 8TB HDD's filled with 1080p mkv's.
I would fucking need Texas for backing this all up.

thats a lot of trap hentai my man

If the data on a hard drive degrades zfs will rewrite it during a scrub so this is a non-issue. What's going to rewrite your up optical media when they start to degrade? How will you even know if it's happening?

I hate both trap and hentai.

Archival BD-Rs. Nothing I do will need to outlive me, so I don't bother with 1000 year meme discs.

I've got triple backups of my data. All of which are covered by ZFS/and or ReFS and Raid Z1/2 & Raid 1/5. Two of those backups are archives shutdown till needed.

I think everyone would agree; backing up 12+TB of data over the internet to the cloud would take fucking forever to do. No to mention the time required to restore it all. Tape was out due to the cost involved. So this way is about as good as it gets yet keeps my data safe.

USB HDD and another USB HDD that is a back up of the back up. I keep one on my desk to access anything I need off of it since I don't keep everything on my main system. The other one is in a fire proof lock box.

Thinking about getting a NAS later this year and dump everything on that.

>12 tb backup to the cloud would take too long
[laughs in gigabit fiber]

>even considering cloud

Originally started my own server due to my growing dvd/cd collection. Decided there had to be a better way to manage it all. So back in 2012 I ripped all my discs and packed them away in storage once I was done. It's (my data) only grown since then. Pictures, other docs, e-books, porn it's all on my server. Replacing some of it would be impossible. Rest of it would be to time consuming now to do from scratch.

why not as another layer of redundancy? Just encrypt and upload, one more layer of redundancy

optical media isnt subject to ferromagnetic depolarization or degradation.
also, true archival storage is offline, cold storage. you arent talking about an archive, but an online / redundant storage solution.

>mfw Jow Forums doesnt even know the difference between an archive and a backup

You can do it tomorrow.

Hard drives don't have to be connected to the internet. Cold storage tape is an artifact of a time before 10+ TB hard drives and modern filesystems existed. No company building a new archival system in 2019 would use tape or optical media.

Learn to draw so I can recreate from memory all the lost hentai

I use DVD disks made of gold pressed latinum

Just print them all off on paper.

NSA has all my shit, ill just give them cunts a ring if i need back ups.

I have enough harddrives to backup the photos I'm just too lazy.
Knowing myself, I will probably back it up when the harddrive start showing real apparent problems, assuming it's not too late by then.
