I have an Urbackup server 2.1.20 who backup 4 Windows stations (images and files).
Everything works fine exept for one client (version 2.1.17) who fail at every image backup. I don’t understand why.
Here are the outputs of /var/log/urbackup.log , c:/Program Files/Urbackup/debug.log , log section client side and log section on the server :

Sry, have looked into this. It’s probably because the sysvol disk size isn’t a mulitple of 4096. This might be fixed with the next 2.2.x client version (not out yet).
I found a solution,
the system disk had a 40MB dell recovery partition on it. I deleted this partition, it was useless in my case.
Now the backup works properly.
