Greetings,
since I could not find a solution to my problem, the best (but long) answer is to re-install and re-do the all backup.
The other part of my quest remain unsolved:
Once all backup (file and image) is done, and I switch to a new OS (Linux in this case), how can I restore my files from a backup?
Can I install a client on linux and read my backup done previously with a a urbackup client?
How can I have the server know that the client should be the same as before?
Please, take in consideration I run URBACKUP on a docker.
I use Portainer as UI.
Probably irrelevant… portainer and so the docker is under Open Media Vault.
Your help is much appreciate.
Thanks
