How reliable is SnapRAID?

programming.dev/post/29024067

programming.devHow reliable is SnapRAID? - programming.devSnapRAID 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 [https://perfectmediaserver.com/02-tech-stack/snapraid/#is-snapraid-right-for-me] 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?

First steps on data hoarding?

programming.dev/post/28526916

programming.devFirst steps on data hoarding? - programming.devI’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.

I've been on a quest to find the Nortel Networks font files.

I have nostalgia for them since my first job was working on projects for Nortel and I saw that font a lot.

There's one single page I've found on the internet that talks about it: luc.devroye.org/fonts-42992.ht

Thanks to archive.org, I found the download page: web.archive.org/web/2004031507

But the actual link to download the file wasn't archived 😢

Digitizing and archiving old dvd collection

lemmy.world/post/27914511

lemmy.worldDigitizing and archiving old dvd collection - Lemmy.WorldOriginal question by @ezyryder@lemmy.dbzer0.com [https://lemmy.dbzer0.com/u/ezyryder] >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 [http://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.

Ripping some Blurays and had to look this up; first time encountering DTS-HD HRA. Apparently it's lossy, but very high bitrate, to the tune of multiple Mbps just for the audio. The "HRA" stands for "High Resolution Audio" and it has no bitrate listed. It's an older movie and there's no DTS-HD-MA track. Decided I'll just package it up in FLAC. That should make it sound as good as possible and FLAC is losslessly compressed so it should hopefully avoid redundant data.

A screenshot from Handbrake of the audio tracks I'm selecting for a movie I'm ripping. The primary track is encoded in the format "DTS-HD HRA".

Recommendations for an inexpensive DIY backup?

sh.itjust.works/post/35471133

sh.itjust.worksRecommendations for an inexpensive DIY backup? - sh.itjust.worksHi 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.
