Who are we?

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

@ray@lemmy.ml Got it done, I'm first of the mods here and will be learning a little Lemmy over the next few weeks.

While everything is up in the air with the reddit changes I'll be very busy working on replacing the historical pushshift API without reddits bastardizations should a PS version come back.

In the mean time you should all mirror this data ensuring its survival, do what you do best and HOARD!!

Anyone used this successfully in their setup?

Garage is an S3-compatible distributed object storage service designed for self-hosting at a small-to-medium scale.

Garage is designed for storage clusters composed of nodes running at different physical locations, in order to easily provide a storage service that replicates data at these different locations and stays available even when some servers are unreachable. Garage also focuses on being lightweight, easy to operate, and highly resilient to machine failures.

Garage is built by Deuxfleurs, an experimental small-scale self hosted service provider, which has been using it in production since its first release in 2020.

Looking to build a collection that I just outright own, so any streaming platform that doesn't allow me to download the raw files is a no go. Other than the big players (Amazon, Walmart, etc.) what are some good sources for buying?

Looking to upgrade my NAS hard drives. Currently have two 4TB WD Red Plus hard drives but I wanted to get some large capacity drives. Was looking into getting 16 or 18TB drives. My current drives are basically whisper quiet and have been running great since 2019 but I feel like it's time to upgrade the capacity.

The NAS is currently on a desk beside my computer. I don't have any cabinets to place it in and would prefer not to connect to it through Wi-Fi. Hence why I'd like for the drives to be as quiet as possible.

I was considering getting a Seagate Exos or Ironwolf (and buying used for the great price) but I've read users online saying they regret buying those models because of their noise. I was also looking at the WD Red Pro but WD's own website only rates them at 3.6/5 with most of the negative complaints about dead on arrival drives. Additionally 25% of all reviews are 1 star; both of which don't fill me with much confidence.

TLDR: What's a quiet and reliable hard drive recommendation for a NAS?

Would it be better just to go with the WD Red Plus at a lower capacity?

Okay, so now that my little experiment with a bunch of scam nvme drive from amazon is done and over with and I got my money back from amazon. Where do I look for some cheap and semi decent 4tb nvmes? Adata used to by my goto budget flash memory, never had any problems with any of their drives. But they're not so inexpensive anymore... Team group seems like they have good prices but how reliable are they?

Is prime day or boxing day even a good time to buy drives?

Is there any 4tb nvme under $300(CAD) even worth looking at?

Again, I'm just farting around and experimenting but any suggestion will be greatly appreciated and win you imaginary internet points from a stranger sitting on a porcelain thrown as he writes this.

I'm trying to digitize some VHS tapes (presumably recorded as NTSC), but I have some questions that I've yet to find answers for. My current process/setup is as follows:

  • VHS tapes are played in a PV-D4745S-K VCR
  • The VCR's composite output is captured using a generic EasyCap capture card.
  • The captured output is fed into OBS Studio with the following settings:
    • A source with it's device set to the capture card, the video format is set to YUYV 4:2:2, the resolution is set to 720x480, the frame rate is currently set to Leave Unchanged (more on this later).
    • Under Settings>Video I have set Common FPS Values with 29.97.
    • I also have set my encoding options under Settings>Output, as well as audio settings under Settings>Audio, but the details of that aren't relevant in this context.
    • I also have deinterlacing disabled by right clicking on the scene and selecting Deinterlacing>Disable.

With this, I seem to be able to capture VHS tapes with decent quality, but I have some nagging questions:

  1. How do I verify if OBS has indeed captured interlaced? I'm trying to capture both fields, but I'm unsure if that's actually happening, and I'm not sure how to go about verifying it.
  2. Should I capture at 29.97 FPS or 59.94 FPS? My thinking is that, given that I'm capturing interlaced, I would think I would multiply the number of captured frames by 2 as, if I understand correctly, each captured frame contains 2 fields, and each would be captured sequentially, so if I want to capture at 29.97 FPS interlaced, I would need to capture at 59.94 FPS. I'm not sure if I'm right about that though.
  3. I mentioned above that the framerate under the source properties is set to Leave Unchanged. The reason for why I chose that option is because the only other options that it offers for framerates are 30.00, 20.00, 10.00, and 5.00 — ie there is no option for 29.97, nor 59.94 — so I'm using Leave Unchanged in the hopes that it's autodetecting the proper frame rate, but that's mostly an assumption on my part. The closest to NTSC's 29.97 would be 30.00, but I'm not sure if this is an issue. And what's confusing me more is that I have 29.97 FPS set under Settings>Video with Common FPS Values and 29.97 set. If I set to source framerate to 30 with OBS at 29.97, will that lead to syncing issues? Is there a way to force the source to use 29.97 to match OBS? What's confusing me further about this is that if I list the formats for the capture device with
    v4l2-ctl --device=/dev/video2 --list-formats-ext
    
    I get the following output (I have truncated it to only list what's relevant, as the full output is long and contains unnecessary information):
    […]
    [0]: 'YUYV' (YUYV 4:2:2)
        size: Discrete 720x480
    […]
         Interval: Discrete 0.033s (30.000 fps)
         Interval: Discrete 0.050s (20.000 fps)
         Interval: Discrete 0.100s (10.000 fps)
         Interval: Discrete 0.200s (5.000 fps)
    […]
    
    There is no option for 29.97 FPS, and, as can be seen by the output, it matches what OBS sees. Is this an issue? It seems, to me, that the capture card isn't capable of proper NTSC framerates, and can only capture at 30 FPS as the closest value.

So i'm testing one of the drives I got on amazon using an old computer. It started off promising, didn't get any errors when formating the drive, write speed using a usb adapter at 25mb/s... Then it dropped off to 7mb/s and the expected time shot up from 40hours to 156h🤣

I'm going to let it run over night and see what happens in the morning. If I can get it to show 4tb without error I might still keep them to test out my geekworm pi nas, otherwise back to amazon you go!

I stumbled upon that new use of mp4 format. Interesting.

I'm sure some of you already using it like this but if not, this could be useful for you.

It creates a directory with the channel's name, create sub-directories with the playlist name, it gives them a number and put them in an order, it can continue to download if you have to cancel it midway.

You can modify it to your needs.

Add this to your ~/.bashrc or your favourite shell config.

alias yt='yt-dlp --yes-playlist --no-overwrites --download-archive ~/Downloads/yt-dlp/archive.txt -f "bestvideo[height<=1080]+bestaudio/best[height<=1080]" -o "~/Downloads/yt-dlp/%(uploader)s/%(playlist_title,single_playlist)s/%(playlist_index,00)s - %(title)s - [%(id)s].%(ext)s"'

You can even limit the download speed by adding this parameter: --limit-rate 640K This example is for 5 Mb/s.

Harvard made available some politics courses entirely for free available on edX which made me nosy to check out other courses in the platform and I'm finding plenty of very interesting courses in there, is there a way to bulk download the courses?

Scouring through amazon for random stuff yesterday, saw these "generic brand" nvmes for $65 a pop. Figured I's give it a shot for my little geekworm pie nas. 4 for the raid and 1 for backup if something goes boogers up. 20tb for $325 was too good to pass up, worse case scenario they are either 1tb each or they fail after a few months. We'll see whats up when they get here in 2 weeks.

Hi, I'm having a bit of information overload. I'm trying to digitize my VHS collection as I know they'll stop working one day, and I'd like to keep their contents around after their analog form has parished. Ive tried startpaging this issue, but I'm honestly overwhelmed. The biggest take-away I have is avoid cheap USB capture devices (EasyCaps and generic variants.) What is the best option for an American on a fixed budget who wants to digitize their collection in the highest quality possible? Ive seen people recommending: TV Tuner Cards RF Video capture via MISRC and Domescape? i think were the names Using a combo DVD/VHS player to copy the VHS to DVD and then ripping the DVD with MakeMKV or handbrake Probably more, I can't recall at the moment but, I'm sure someone will.

Basically, if I dont have to spend money, I would prefer not to, but I do want a quality recording/rip. I know for a fact anything over $200 USD is going to be out if my budget. I have sufficient Linux knowledge and soldering knowledge and I have seen some people those are needed for the RF tools, but I also see some of those options are pricy.

Lemmings, what are your opinions on my situation? Is there anything short of an easycap in my budget that I should be looking into? What are your experiences? Thanks.

SnapRAID doesn't compute the parity in real time, so there's this window between making a change to the data and syncing where your data isn't protected. The docs say

Here’s an example, you acquire a file and save it to disk called ‘BestMovieEver.mkv’. This file sits on disk and is immediately available as usual but until you run the parity sync the file is unprotected. This means if in between your download and a parity sync and you were to experience a drive failure, that file would be unrecoverable.

Which implies that the only data at risk is the data that's been changed, but that doesn't line up with my understanding of how parity works.

Say we have three disks that store 1 bit of information and a parity drive: 101 parity 0. If we modify the data in the first disk (data 001 parity 0), then the data is out of sync. Say we now lose disk 2 (data 0?1 parity 0). How does it then recover that data? We're in an inconsistent state where the remaining data tells us that drive 2 used to hold 0^1^0=1 when it actually held a 0. So doesn't that mean that between any modifications and a sync operation, all your data in that disk region is now at risk? Does SnapRAID do anything special to handle this?

I'm thinking of backing all of my family's digital assets up. It includes less than 4 TB of information. Most are redundant video files that are in old encodings or not encoded at all and there are a lot of duplicate images and old documents. I'm gonna clean this stuff up with a bash script and some good old manual review, but first I need to do some pre-planning.

  • What's the cheapest and most flexible NAS I can make from eBay or local? What kind of processors and what motherboard features?
  • What separate guides should I follow to source the drives? What RAID?
  • What backup style should I follow? How many cold copies? How do I even handle the event of a fire?

I intend to do some of this research on my own since no one answer is fully representative but am appreciative of any leads.

My partner's grandmother has passed and has left a collection of hundreds possibly thousands of DVDs. These range from official releases to pirated and bootleg copies.

What would be the best way to digitize and archive this collection? Is there an external device out there that will let me burn and convert the DVDs? I'd want to possibly upload on archive.org if the copyright expired, store on backblaze or maybe another digital archiving site besides a regular torrent, would appreciate any recs on sites and advice in general. I haven't gone through these yet but figure the project would be a fun learning experience.

Hi there, I've been meaning to go get more serious about my data. I have minimal backups, and some stuff is not backed up at all. I'm begging for disaster.

Here's what I've got: 2 8tb drives almost full in universal external enclosures A small formfactor PC as a server, with one 8tb drive connected. An unused raspberry pi. No knowledge of how to properly use zfs.

Here's what I want: I've decided I don't need raid. I don't want the extra cost of drives or electricity, and I don't need uptime. I just need backups. I want to use what drives I have, and an additional 16tb drive I'll buy.

My thought was that I would replace the 8tb drive with a 16tb one, format it with zfs (primarily to avoid bit rot. I'll need to learn how to check for this), then back it up across the two 8tb drives as a cold backup. Either as two separate drives somehow? Btrfs volume extension? Or a jbod connected to the raspberry pi, that I leave unplugged except for when it's time to sync the new data?

Or do you have a similarly cheap solution that's less janky?

I just want to back up my data, with an amount of rot protection, cheaply.

I understand that it might make sense to invest in something a bit more robust right now, and fill it with drives as needed.

But the thing I keep coming to is the cold backup. How can you keep cold backups over several hard drives, without an entire second server to do the work?

Thanks for listening to my rambling.

Archive Team has just begun the distributed archiving of the Japanese SS Blog, a blog hosting service, which is set to be discontinued on March 31, 2025.

And you can help! There isn't much time left, so as many people running the warrior as possible is needed.

Resources:

  • The wiki page of the project (not much info)
  • The tracker (at the top of the page) has the simplest info on how you can help out
  • The github page offers a docker-based alternative for advanced users, and more info on best practices for this sort of archiving

Why help out?

The web is disappearing all the time, and often a lot of previously easily accessible information is lost to time. These japanese blogs may not be very important to you, but they certainly are to a lot of people, and nobody knows what sort of information is found only here, until they need it.

This is the first time I am uploading patched Roms, unlike previously where I uploaded only the patch files. My personal collection of Super Nintendo Romhacks in ready to play patched Roms in .sfc and .smc formats, complete with a descriptive text document. Most, if not all, files are patched by myself, but I did not test every game yet. Some old Romhacks do not work in accurate emulators.

Please share this everywhere where Rom files are allowed to be shared. I am only sharing here at the moment.

This collection comes in two variants: flat structure, and sub structure. "flat" just means all Roms and documents are saved in one single directory. "sub" means, every game got its own dedicated directory, where only related Romhacks and Mods are saved.

For years I've on and off looked for web archiving software that can capture most sites, including ones that are "complex" with lots of AJAX and require logins like Reddit. Which ones have worked best for you?

Ideally I want one that can be started up programatically or via command line, an opens a chromium instance (or any browser), and captures everything shown on the page. I could also open the instance myself and log into sites and install addons like UBlock Origin. (btw, archiveweb.page must be started manually).

Hi all,

I've been thinking about picking up an N150 or 5825U MiniITX board for a NAS, but I'm wondering if there are better options given my requirements.

  • At least 2x 2.5Gb LAN
  • A 10Gb LAN, or 2.5Gb if not
  • 2x NVME
  • 8x SATA for spinning disks
  • 2x SATA for SSDs
  • MiniITX is required for the 10" rack
  • 64+ Gigs of RAM (ZFS cache) (This is not possible on an N150)

The problem I'm running into with the boards I've looked at is PCIe lanes, and not having ways to expand the sata or network ports without stealing from NVME.

I've started to look at boards with PCIe 4.0x16 slots and risers/splitters for expansion, but then I can't find low power CPUs for them.

Thoughts?

A team of volunteer archivists has recreated the Centers for Disease Control website exactly as it was the day Donald Trump was inaugurated. The site, called RestoredCDC.org, went live Tuesday and is currently being hosted in Europe.

As we have been following since the beginning of Trump’s second term, websites across the entire federal government have been altered and taken offline under this administration’s war on science, health, and diversity, equity, and inclusion. Critical information promoting vaccines, HIV care, reproductive health options including abortion, and trans and gender confirmation healthcare have been purged from the CDC’s live website under Trump. Disease surveillance data about bird flu and other concerns have either been delayed or have stopped being updated entirely. Some deleted pages across the government have at least temporarily been restored thanks to a court order, but the Trump administration has added a note rejecting “gender ideology” to some of them.

“Our goal is to provide a resource that includes the information and data previously available,” the team wrote. “We are committed to providing the previously available webpages and data, from before the potential tampering occurred. Our approach is to be as transparent as possible about our process. We plan to gather archival data and then remove CDC logos and branding, using GitHub to host our code to create the site.”

they made cool workout posters, and still do, but I think they got dmca'd in 2016. the superheroes are all gone.

navigating archive. org is slow and often leads to "no hotlinking" and unavailable Google drive PDFs.

anyone got these stocked somewhere?
