Bugs in Urbackup

Fist I would like to thank to all developers and community for their work, Urbackup is nice piece of work.

But it doesn’t work, setting of new client is always lottery (linux server, windows clients), no log entries at all, sometimes it start working after few client un/reistalls, but now I’m stuck, 1 week client doesn’t connect to server (local network, no logs or errors at all). Big issue is also language setings, it must be possible to select language (would be better for bug reporting, if language is not english).

Client file backup interval still not fixed, I know this is free software, but bugs reported months/years ago should be fixed an they must be not present in new releases, please.

I’m thinking out moving to QNAP or Synology.

Funny i have the opposite experiences, i have zero issues getting clients to connect, even from WAN. Things to keep in mind: firewall on the client, client auth key, server url and client name, restart the client backend when you changed those. Client auth key is in the client specific settings on the web interface. On lan it takes a couple of minutes for the server to see the client online, maybe be a little more patient?

Language settings? You mean for the windows client gui? I have one instance where that is installed and it automatically switched to Dutch (because my dad’s laptop is localized to Dutch). But i think i remember looking for a way to change that, and could only find a way to force it to english via manually removing the translation files, if i recall correctly. I think i have also left a post here somewhere about this; urbackup seems to look at location rather than language settings to determine the language, that is why i needed the trick to switch to english (back when my daily was still running windows, for the tray app). Today i manually updated the windows client app and noticed the first thing it asks is what language, may have been a new addition to the new version, possible reinstalling it and selecting the right language that way works?

It uses the system language ( urbackup_frontend_wx/main.cpp at dev · uroni/urbackup_frontend_wx · GitHub ). I think this is the correct thing to do in general. Otherwise you’d have to have a localization dialog separately for every app including things like comma separator and date format.
What you saw is setting the language for the installer (yeah, it is not consistent…).

Ah, that might explain things; the user display language is not always the same as the system language. I ran a test; i have vm with windows 10 that has Dutch date formatting and such (see just above the top drop-down: English with Dutch between parentheses) but display language in EN and timezone set to NL.


I took a snapshot and when i install the client it presents itself in English, just as expected. When i roll back to the snapshot, and switch the System Locale to Dutch like so:

reboot, and install the client, the client is still in English, perfect.
But when i do it “the proper way” and select Dutch as the display language:

and then

(btw this used to be only possible with Windows Pro/Enterprise, not sure if this is possible with “Home” versions). And i just assume the same behavior applies to Windows 11, but that is something for OP to find out.
Wait for it to install, sign out, confirm everything in windows (menus and such) are displayed in Dutch (note AFTER logon, and also note: some programs like firefox might still display English, they have their own settings).
And then install the current Urbackup Client which correctly preselects the installer language to Dutch:

And guess what? Its behaves exactly like it should:

(also when i hover over the tray icon the text presented is in Dutch).
So what i saw earlier (i have found it back: How to set the client language on Win 10) is not what i see happen now. Back then what i saw happen was basically at what i tried first here (everything was set to English, just formatting and timezone set to Dutch) is that the client presented itself in Dutch, which was quite annoying. But im done with Windows anyway and i dont have the client frontend on my Debian, i spend way too much time looking at the admin webpage anyway.

But fwiw: hope this helps OP: check if you have the display language preferences set to the same language you want the Urbackup Client to show up with. It could mean you need to reinstall the application if you change that afterwards, im not able to tell when that is set, i suppose in an ideal world that would happen dynamically but its a little effort.
Ok, im convinced its done the proper way Martin, ill follow up the other thread with a link to here, maybe that helps the other person too. Possibly things changed in the meantime, great stuff.
