⁨Comment⁩ on ⁨Tell me the truth.⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
You’re just repeating the definition that I’ve already made clear I disagree with. This definition isn’t science, it’s taxonomy. Taxonomy is just a tool; we to group similar entities together so we can characterize them. A body’s orbit and neighbors aren’t as important for that purpose as other attributes like size and composition.

Should they be considered planets? No, of course not.

Why not?
⁨Comment⁩ on ⁨Tell me the truth.⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
I’m saying that (most) moons are planets too. Anything big enough to be round, but not big enough to burn hydrogen, should be a planet regardless of where it orbits.
⁨Comment⁩ on ⁨Tell me the truth.⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
Why does the definition involve location? Intrinsic properties make more sense. Who cares what it orbits or what else is is in a similar orbit?
⁨Comment⁩ on ⁨Tell me the truth.⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:
They should have done that

And the IAU got it wrong when they reclassified Pluto. Jupiter and mercury belong in the same category but the moon and mercury don’t? Get the fuck outta here

I looked into tape drives for my own backups and they don’t make sense unless you’re working with double digit terabytes. We’re talking used old enterprise gear with weird form factors and connectors, I never found something like an external USB tape drive for a reasonable price.

Do you remember what kind they were? For awhile they made them with organic dyes and those died quickly. I believe they stopped producing those, and the inorganic ones are supposed to be much better.

It’s pretty dependent on humidity and temperature, so a DVD buried in a well sealed plastic bag with a desiccant packs is actually in good conditions. No light, generally cool, and low humidity are perfect.

A hard drive has a lot of moving parts that must work and are basically impossible to replace. With optical media you’re just storing the platters, and I’m sure you’ll still be able to track down a drive somewhere. You can still find VHS players and those have been obsolete for 25 years.

I’d go with optical media here. Probably multiple capsules.
- M-Disk (DVD if it will fit, otherwise Blu-ray)
- Make an encrypted archive of your data. Strong password - I suggest diceware with 8 or more words so you might remember it in 30 years
- Use DVDisaster to add parity data. You sacrifice some space, but you get error tolerance in exchange
- Wrap the disks up in good jewel cases, well sealed plastic, along with some good big silica gel desiccant packs.
- Put all that in the smallest durable, airtight container you can
- stash somewhere it probably won’t be disturbed for a few decades. Memorize.
- destroy all evidence you did this.
⁨Comment⁩ on ⁨Looking for recommendations for a multi home NAS solution⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
Yeah, syncthing can do all of that except public share links. Run an instance on your NAS so there is always a sync target online.
⁨Comment⁩ on ⁨Looking for recommendations for a multi home NAS solution⁩ ⁨⁨4⁩ ⁨weeks⁩ ago⁩:
Id strongly recommend ZFS as a filesystem for this as it can handle your sync, backup, and quota needs very well. It also has data integrity guarantees that should frankly be table stakes in this application. Truenas is an easy way to accomplish this, and it can run docker containers and VMs if you like.

Tailscale is a great way to connect them all, and connect to your nas when you aren’t home.

I’ll caution against nextcloud, it has a zillion features but in my experience it isn’t actually that good at syncing files. It’s complicated to run and there are frequent bugs. Consider just using SMB file sharing (built into truenas), or an application that only syncs files without trying to be an entire office suite as well.

For your drive layouts, I’d go with big drives in a mirror. This keeps your power and physical space requirements low. If you want, ZFS can also transparently put metadata and small files on SSDs for better latency and less drive thrashing. (These should also be mirrored.) Do not add an L2ARC drive, it is rarely helpful.

The boxes are kinda up to you. Avoid USB enclosures if at all possible. Truenas can be installed on most prebuilt NAS boxes other than synology, presuming it meets the requirements. You can also build your own. Hot swap is nice, and a must-have if you need normies to work on it. Label the drive serial number on the outside so you can tell them apart. Don’t go for less than 4 bays, and more is better even if you don’t need them yet.

Have you considered karakeep (formerly hoarder)? It does all of this really well - drop it a URL and it saves a copy. Has lists & tagging (can be done by AI if you want), IOS & android apps as well as browser extensions that make saving stuff super easy.

Dude, the same people made nine parchments which got me and my friends through the pandemic. It’s such a good game and I don’t think we’ll ever get a sequel :(

It worked for us because you could do combo co-op: my wife and I sharing a switch at our place, friends (also a couple) on their switch at their place.

It’s a bit like a very simplified Diablo, with friendly fire. Minimal loot and a 5 color elemental system. Mostly achievement based unlocks. Has a permadeath mode where if you wipe as a party, you have to start the campaign over. Fun, whimsical art and the music ain’t bad either. My only real criticism is that they put so little effort into the plot I wonder why they bothered at all, but it does stay out of your way for the most part

I only looked how zfs tracks checksums because of your suggestion! Hashing 2TB will take a minute, would be nice to avoid.

Nushell is neat, I’m using it as my login shell. Good for this kind of data-wrangling but also a pre-1.0 moving target.

⁨Comment⁩ on ⁨Incremental backups to optical media: tar, dar, or something else?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
Where I live (not the US) I’m seeing closer to $240 per TB for M-disc. My whole archive is just a bit over 2TB, though I’m also including exported jpgs in case I can’t get a working copy of darktable that can render my edits. It’s set to save xmp sidecars on edit so I don’t bother with backing up the database.

I mostly wanted a tool to divide up the images into disk-sized chunks, and to automatically track changes to existing files, such as sidecar edits or new photos. I’m now seeing I can do both of those and still get files directly on the disk, so that’s what I’ll be doing.

I’d be careful with using SSDs for long term, offline storage. I hear they lose data if not powered for a long time. IMO metadata is small enough to just save a new copy when it changes
⁨Comment⁩ on ⁨Incremental backups to optical media: tar, dar, or something else?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
I’ve been thinking through how I’d write this. With so many files it’s probably worth using sqlite, and then I can match them up by joining on the hash. Deletions and new files can be found with different join conditions. I found a tool called ‘hashdeep’ that can checksum everything, though for incremental runs I’ll probably skip hashing if the size, times, and filename haven’t changed. I’m thinking nushell for the plumbing? It runs everywhere, though they have breaking changes frequently. Maybe rust?

ZFS checksums are done at the block level, and after compression and encryption. I don’t think they’re meant for this purpose.

⁨Comment⁩ on ⁨Incremental backups to optical media: tar, dar, or something else?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
Yeah, you’re probably right. I already bought all the stuff, though. This project is halfway vibes based; something about spinning rust just feels fragile you know?

I’m definitely moving away from the complex archive split & merge solution. fpart can make lists of files that add up to a given size, and fd can find files modified since a given date. Little bit of plumbing and I’ve got incremental backups that show up as plain files & folders on a disk.
⁨Comment⁩ on ⁨Incremental backups to optical media: tar, dar, or something else?⁩ ⁨⁨4⁩ ⁨months⁩ ago⁩:
Ohhh boy, after so many people are suggesting I do simple files directly on the disks I went back and rethought some things. I think I’m landing on a solution that does everything and doesn’t require me to manually manage all these files:
- fd (and any number of other programs) can produce lists of files that have been modified since a given date.
- fpart can produce lists of files that add up to a given size.
- xorrisofs can accept lists of files to add to an iso
Image

So if I fd a list of new files (or don’t for the first backup), pipe them into fpart to chunk them up, and then pass these lists into xorrisofs to create ISOs, I’ve solved almost every problem.
- The disks have plain files and folders on them, no special software is needed to read them. My wife could connect a drive, pop the disk in, and the photos would be right there organized by folder.
- Incremental updates can be accomplished by keeping track of whenever the last backup was.
- The fpart lists are also a greppable index; I can use them to find particular files easily.
Downsides:
- Change detection is naive. Just mtime. Good enough?
- Renames will still produce new copies. Solution: don’t rename files. They’re organized well enough, stop messing with it.
- Deletions will be disregarded.
- There isn’t much rhyme or reason to how fpart splits up files. The first backup will be a bit chaotic. I don’t think I really care.
Honestly those downsides look quite tolerable given the benefits. Is there some software that will produce and track a checksum database?

Off to do some testing to make sure these things work like I think they do!

Hey cool, I hadn’t heard of bacula! Looks like a really robust project. I did look into tape storage, but I can’t find a tape drive for a reasonable price that doesn’t have a high jank factor (internal, 5.25" drives with weird enterprise connectors and such).

I’m digging through their docs and I can’t find anything about optical media, except for a page in the manual for an old version. Am I missing something? It seems heavly geared towards tapes.

Can borg back up to write-once optical media spread over multiple disks? I’m looking through their docs and I can’t find anything like that. I see an append-only mode but that seems more focused on preventing hacked clients from corrupting data on a server.
