FR: Progress Sync - alternative sync server options

[mergen3107]

Does your feature request involve difficulty completing a task? Please describe.
Can we please have an option to sync progress over, say, webdav or dropbox?

Describe the solution you'd like
The problem is that recently the rocks.koreader server was down a few times. It is currnently down for the last 3-4 days.

Describe alternatives you've considered
We have Cloud storage working - why can't we sync progress to there?
All it needs to do, is upload and download sync files (a few KB), right?

Additional context
I haven't used progress sync at all before, I don't have any idea of how set it up right now (with server down). Please direct me in the right direction.
I've read the Wiki, a link to which I found in the User Guide.

(by the way, @offset-torque and everyone who helped, thank you sooo much for doing the whole User Guide adventure, I found it like 30+ times useful within a day of setting up a new device - ALL the keywords found in the KOReader I was able to find in the User Guide, you have phenomenal attention to details).

It's not a file, or a DB like the stats, it's all live over a REST API.

Which means doing it another way would basically require crafting something entirely new ;).

I run a small instance of a different server implementation at https://kosync.ak-team.com:3042 but it's not a mirror, so it uses its own database. (It's also on the other side of the Atlantic, which happens to be a plus in my case ;p).

https://github.com/koreader/koreader-sync-server#setup-your-own-server is the main implementation (setup guide in README.md). There's also https://github.com/jberlyn/kosync-dotnet (unofficial).

I think the main difference is that you can disable registration on the unofficial one and it's written in dotnet https://old.reddit.com/r/selfhosted/comments/13o9gv3/my_first_selfhosted_software_contribution_a/

Thank you guys!

There are alternatives in many languages btw, not just C#.

Thanks for the kind words mergen3107. Good to have feedback from field testing. I am glad that user guide is as useful as I intended.

Another sync server wide open, allowing registrations, this one maintained by me. The server itself is on a datacenter near Paris, France:

https://kosync.duckdns.org

It is using https://github.com/lzyor/kosync under the hood
