I think for now Forgejo is a drop-in replacement. However since they are a hard-fork, at some point in the future they will diverge enough to be mutually incompatible, so the clock is ticking on migrating.

If you’re not storing on a filesystem that calculates and checks erasure codes then you can always generate PAR2 files yourself.

What was your XMPP client connecting to? Was it a well-known public endpoint (that they could be whitelisting) or was it a private server? If the latter then that indicates that they are allowing arbitrary IP connections which in theory means that you should be able to proxy any traffic you want. I doubt they are doing DPI, since TLS makes this very difficult these days when you don’t control the certificate stores on the clients.

I’d imagine they’re relying on some combination of DNS whitelisting and port blocking which should be trivial to circumvent if you know ahead of time what traffic they allow through.

It sounds like they have some nice improvements, but I wonder why they didn’t contribute them back to the original restic project.

I also wouldn’t rely on an immature piece of software to handle backups - you want to avoid as many risk factors as possible with backups, since when you need to restore you really need it to work.

Thanks for posting this. I’ve been meaning to write something similar for a while but never got around to it. I wish Restic would ship an official client application for managing this stuff!
