Hi there !
I’m sorry if this is not the right place to ask, let me know and I’ll create a new thread… Well, I have a windows computer with a broken hard drive and I was backing it up via internet and image backup with 2.1.20 server and 2.0.36 client, the backups seems alright so I would like to restore the system on the new hard drive I installed on the computer.
I boot with the urbackup_restore_2.1.1 iso (on usb pen) but I struggle to launch the recovery…
I see there is an option to connect to internet server but I can’t manage to make it connect, sorry if the solution is obvious but I really have issue to find how to authenticate 
Every time I enter the server address and port, then I have to provide the Internet server restore authentication key and that the issue, I don’t know what it is !
I looked on the user folder and found a lot of files, maybe I have to write some informations on some files ? What I tried with no success is to copy the server_ident.key I found on the server, I removed the preceding ’#I’ and ’#’ at the end of the contents of ’server_ident.key’ as I found in the documentation with no luck…
I also tried with the internet auth key that can be found in the settings/client section on the webpage with no more success…
I fact I don’t understand why I have to provide this key in place of the username/password (or I imagine it would be the next step since I saw the text that ask it in a file in folders of the restaure image…)
Every time I have the following message : “following error happened: authentication with internet server failed with status error : authentication failure : unknown client (##restore##jkjkgsbgjkregh4567)”
Please can someone tell me the steps I have to do ? Do I have to write some IDs in some text files on the client ? I’m sure I’m not so far to make it work but I tried so much combinations since hours with no result ! 
This computer is very important there is unique data and piece of software and configs and so on… and I can’t get it back without this restore… thank you very much for your help…
