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…

yeah like a lot of OSS backup products the docs are grandiose without focusing on ease of operation / feature parity with dropbox

Perkeep is really straightforward to operate though. One can just install the dmg, mount the root and put files there. Also there's a web interface. For me the most interesting feature is though how easy it is to setup a new node and to sync to/from it. Like rsync but no need to worry about the parameters. Also as the name suggests, it's far more difficult to loose important data than with Dropbox (and similar products like iCloud) which can quickly happen through wrong usage.

The first sentence on the site ("Perkeep [...] is a set of open source formats...") describes literally what the thing is, but not at all what it _does_. Not to slam on these cats, because marketing copy is _hard_. For project collaborators, or open-source dorks who live in this kind of world anyway, the sentence on the homepage is probably perfectly…

As an engineer

> files or objects, tweets or 5TB videos

means rsync, curl, and Twitter API integration. It obviously does more than this, since I can throw something together that does that in a few hours. Where is the list of everything it supports?!?

That should be front and center.

I managed to parse it, but there's a great grabber sentence down below that might be right at the top:

"Your data should be alive in 80 years, especially if you are." To which you might add, "We're here to help you make sure that's what happens". Then follow that with the "Things Perkeep believes ..." section.

After that, the mission is clear, how it works is clear (though many people might have -no idea- what 'Open source' is good for). Only Then (IMO) can you get away with going all technical on them!

Do proper use of ZFS also require ECC memory?

100% yes. With non-ECC you will always have bad RAM bits eventually. With ZFS this is especially bad because it can corrupt your checksums or your ZFS metadata, which means either silently corrupting your data, or corrupting ZFS itself and losing your entire zpool (akin to losing a RAID array).

This is FUD perpetuated by a certain individual on the FreeNAS forum.

You can buy a 2tb drive for $100. $200 and you've got 430 DVD's worth of data redundantly stored. $300 and you've got local redundancy AND offsite backup.

Even if magnetically they don't have 'bit rot', they use bearings where the lubrication can dry up and wear out when they're not turning for long periods of time. You need to keep them spinning on a regular basis, and replace them as they begin to fail.

Ideally you would temporally separate the purchasing of the drives and make sure to hook them up and check them every so often (once a year?).

Much like other commenters I'm no expert on the topic, but I think you'd have to be pretty incredibly unlucky to have a mechanical failure on 3 drives at once from lack of use, especially if they were from different manufacturing batches.

I felt the same but if you go to "Docs" the very first link is then:

"Overview: The original motivation and background for why Perkeep exists and what one might use it for."

And there I found a great description.
