No worries, good question :>

The problem with bidirectional filesync is that it’s an absolutely massive can of worms, very easy to mess up, and the consequences of messing up are usually the worst kind (loss of data). There’s an insane amount of edgecases to keep in mind, and you need to get every edgecase right every single time, otherwise you might wipe someone’s vacation photos, or suddenly downgrade someone’s keepass database to an older version… And stuff like syncing multiple devices to the same server makes it balloon further.

I’ve started becoming more confident in copyparty’s filesystem-index database, but it’s still just a hint/guideline, with the filesystem being the only source of truth – it’s still not something I’d trust with tracking sync-state against one or more clients.

The bigger guys who offer bidirectional sync (nextcloud, syncthing, etc.) have spent years perfecting their logic, so I’d like to leave this in their capable hands.

Yep! Depending on what your home connection looks like, you have a few options:

if you are lucky enough to have your own private IP-address and are able to open ports, then you’re almost done already – you can put copyparty on some port (or keep the default 3923), and then anyone could connect to it by going to https://your.ip.address:3923/

(with this approach, you will want to create your own HTTPS certificate so the traffic is properly encrypted – the best option here is to get a domain and get a certificate for the domain)

however, if you are behind CGNAT, meaning your internet provider has given you a shared IP-address, then people cannot connect directly to your home-PC. One way around that issue is by setting up a machine somewhere on the internet which bridges the gap back home to your PC. Cloudflare offers this as service, and this is explained in the copyparty readme – see the “at home” section for one way to do that.

if you are against using Cloudflare for idealistic reasons (they are becoming quite powerful since they run a whole lot of the internet), then you can set up a cheap VPS which serves the same purpose. That’s my setup, and how you are accessing the copyparty demo server right now – I have the cheapest VPS you can get from Hetzner. The VPS is running nginx, and it forwards the traffic to my homeserver through an SSH tunnel. I haven’t documented this approach in the copyparty readme, but I have a feeling a lot of other people have :>

SFTP is not currently on the roadmap, but it’s not entirely implausible.

FTPS is supported, but it requires an optional dependency to be installed (pyopenssl), so it’s not available in the Windows EXE. And I just realized that the dependency is currently not present inside the docker images either, so I’ll get that fixed right away.

Not proxmox-specific, but I’ve been using btrfs on my servers and laptops for the past 6 years with zero issues. The only times it’s bugged out is due to bad hardware, and having the filesystem shouting at me to make me aware of that was fantastic.

The only place I don’t use zfs is for my nas data drives (since I want raidz2, and btrfs raid5 is hella shady) but the nas rootfs is btrfs.

I’m sorry to say it’s a bit of very old-fashioned php that’s in charge of all that xD

I’ve modified it to print its own source code if you append ?dat=sauce to the URL, and I’ll try to answer questions if I can remember how it worked :-)

oh good, that’s just reader-mode mangling the TOC. Those are supposed to be clickable links to jump to the relevant section. Firefox’s reader-mode does a better job by not rendering the TOC at all. Thanks for the scare hehe

Hey! Website author here :>
Curious about the SEO garbage you’re seeing because that’s not coming from me. Could you post an example? Are you using any shady VPN’s or anything like that?
