Image backups wont start for nothing!

I had to reinstall urbackup server on new hardware and did a fresh configuration over the new version and created all clients and confs frmo stratch. The problem is that i cannot do image backups at any cost. File backups (incremental/complete) do perfectly but not images, debug dont show anything either from server or client side. And yes, i have enabled image backups… Can anyone shed a light ?

Found out that general settings arent being applied to clients, dunno why…
And that after i defined C volume to backup on each client it starts to do images.
