I admire the goal of reliable long term data storage. I don't need to store tweets or 5TB videos, but my current solution is duplicate DVDs with a bunch of par2 files to hopefully ward off bit rot. I feel like there's some room for improvement.

I suggest trying syncthing. It is a cross platform P2P file synchronization tool, super easy to setup.

You don't need funding for focusing on ease of operation, it's a mindset. Either you're user-centered, or you're not.

>Either you're user-centered, or you're not. It really depends on the audience for the product, targeting regular users does require more thought on the UX, etc which almost invariably means more funding.

I don't think the website targets the wrong audience - just the copywriter was so involved in the project they forgot to make what they're offering clear.

When someone says "permanently keep your stuff, for life" do they mean some sort of pay-once eternal backup, like permanent.org? Something censorship-resistant, like Freenet? Something peer-to-peer and distributed-ledger based like Filecoin? Backing up data locked up in cloud services? Converting obscure file formats into ones with more longevity? Bypassing defunct DRM? Activism against civil forfeiture?

Wow, it was really hard to find out what this software does. I finally found a demo at the end of an hour-long talk from 2 years ago: https://youtu.be/PlAU_da_U4s?t=2687 So it seems to have a bunch of scripts to import data into its database from a variety of sources (including cloud services), and provides a search interface to navigate that historical data. And it has a lot of under-the-hood stuff about replication…

You initial confusion and nice summary made me thought of camlistore which I looked at 4 or 5 years ago. And here it is, renamed! This is sad because the project looks interesting, it is not the usual quick kludge or vaporware, but the bad or inexistent documentation is a terrible disservice to the project.

Perkeep is camlistore, FYI.

Agreed. I used to back up onto DVDs, creating a set of (say) 12 DVDs with an extra couple generated by par2, to take care of the case where some of the DVDs just straight aren't readable. However, I found that I had a lot of data to back up, and it was actually cheaper and less tedious to get 4TB USB hard drives for ~£100 each, and plug them into an old defunct EeePC901 (with the added advantage that if the power goe…

Re: 4Tb drives, I do the dollars-per-mb calculation before buying hard drives. The most recent time I included the enclosure cost and found that it was actually cheaper to go huge. Granted the enclosure was a Synology, but buying 16TB drives is the closest I’ve been so ‘solving’ storage in a long time. Formatting them and adding them to the array was brutal, and they are noisy, but it has been worth it.

Yeah, I'm using 4TB laptop-sized (2.5") external USB drives, because they are small, cheap, quiet, and they don't need a secondary power supply. At the time of purchase, they were the sweet spot, with 5TB drives considerably more expensive. That may have changed now.

If you're going for 3.5" drives, then yes I can well believe that the sweet spot is with slightly larger drives, especially if you take enclosures into account. I did the calculations for work a while back for shoving hard drives into something from https://www.45drives.com/ and it seemed that getting the largest drives possible was the best price/capacity option.

Interestingly, on my home ZFS raidz with 3 4TB hard drives, I have had to replace a drive a couple of times because ZFS scrub was reporting silent corruption. They were consumer-grade SATA drives. However, at work, I have backed up ~200TB of data to a large server with RAID-6 and ext4, storing the backups as large .tar files with par2 checksums and recovery data, and regularly scrubbing the par2 data. I have yet to s…

Thanks. What are the drives at your workplace?

I actually have no idea. I didn't have any part in purchasing that particular system, I don't have root, and all the drives are hidden behind a RAID controller. Sorry.

Does anyone know how mature Perkeep is? Is anyone using it regularly? Would love to hear if there is anyone who has experience with it.

I'm guessing not very: "The latest release is 0.10 ("Bellingham"), released 2018-05-02"
