Thanks 👍

I think that change was done way back when. Do you have a reference for the algorithm change? I tried a quick search and came out empty.

Really? I was able to comment a couple of minutes ago.

Yeah I have no hope for an American FOSS design.

Perhaps an EU-backed one might appear at some point.

Recently I stumbled upon a Chinese team working on a FOSS pair of cores, with source in GitHub. I think they were aiming at competing with A76 and N2. Supposedly they’re well underway.

Found it

If these guys (or any others) tape out a competitive FOSE chip, it’ll change the world. If it’s a decent project, everyone and their mother will fork it. And we’ll get chips that cost just a bit over the silicon and packaging cost.

A high performance RISC-V CPU core.

A for profit worker co-op is very different than a private for-profit. A for-profit worker co-op would be fine ik my book and in fact preferable than a non worker co-op nonprofit.

I think there’s a difference in definitions, as well as difference between non-profit/not-for-profit and charities. As far as I know what your described is a non-profit and a non-profit can sell services.

Right so I guess the question of 3 is whether it means 3 backups or 3 copies. If we take it literally - 3 copies, then it does protect from user error only. If 3 backups, it protects against hardware failure too.

E: Seagate calls them copies and explicitly says the implementer can choose how the copies are distributed across the 2 media. The woodchipper scenario would be handled by the 2 media requirement.

Hm I wonder why snapshots wouldn’t satisfy 3. Copies on the same disk like /file, /backup1/file, /backup2/file should satisfy 3. Why wouldn’t snapshots be equivalent if 3 doesn’t guard against filesystem or hardware failure? Just thinking and curious to see opinion.

• Primary ZFS pool with automatic snapshots
  • Provides 3+ copies of the files via snapshots (3)
• Secondary ZFS pool at a different location replicates the primary
  • Provides more copies of the files (3)
  • Provides second media (2)
  • Is off-site (1)

Does this make sense?

The answer for doing this on your PC is Docker with one of the open source containers built for this. For example this.

If you want a dedicated machine, your Pi would do just fine but you’ll have to connect your storage where the downloads are to it. You should still use Docker for that since it’s the easiest setup and it would take care of important corner cases such as blocking seed when the VPN is down.

If Raid is backup, then Unraid is?

Try ZFS send if you have ZFS on the other side. It’s insane. No file IO, just snap and time for the network transfer of the delta.

Every hour. Could do it more frequently if needed.

It depends on how resource intensive the backup process is.

Consider an 800GB Immich instance.

Using Duplicity or rsync takes 1 hour per backup. 99% of the time is spent in traversing the directory structure and checking which files have changed. 1% is spent into transferring the difference to the backup. Any backup system that operates on top of the file system would take this much. In addition, unless you’re using something that can take snapshots of the filesystem, you have to stop Immich during the backup process in order to prevent backing up an invalid app state.

Using ZFS send on the other hand (with syncoid) takes less than 5 seconds to discover the differences and the rest of the time is spent on the data transfer, at 100MB/s in my case. Since ZFS send is based on snapshots, I don’t have to stop the service either.

When I used Duplicity to backup, I would backup once week because the backup process was long and heavy on the disk array. Since I switched to ZFS send, I do it once an hour because there’s almost no visible impact.

I’m now in the process of migrating my laptop to ZFS on root in order to be able to utilize ZFS send for regular full system backups. If successful, eventually I’ll move all my machines to ZFS on root.

What’s the second B stand for?

WTF, I always thought Dr. Oetker was just another brand of some American multinational. It’s apparently German.

I think you are underestimating the effect. I’ve learned a whole lot in my year and a half here. Enough to develop a decent understanding of what’s going on and what concrete actions I could take in my corner of the world. I think we can’t expect action without understanding of why act and what action. I think discussions here help with that. For all the people who post and comment, there are many who read, learn go find out more, and so on. Some of those would take action that they wouldn’t have otherwise. If we don’t platform that do this, if all there is are corporate platforms that keep people unaware of even the basics of what’s happening beyond the reporting, then the number of people who’d act in some productive way would be even lower.

Old Social Media

Oof, heavy shade. Well done! Makes the Fediverse sound cooler.

Since the project is already okay with Github, perhaps a set of polls in Github with this feature, linked far and wide in Lemmy.

That’s a great point and a really low hanging fruit that would likely help with adoption and retention. The defaults weren’t great for me either.
