Software Urbackup

Hello, I have been working with your software for a few months now.
After several tests, I think that I do not know how to use it completely
because I encounter some difficulty for the configuration or it comes
from some bug.

  • when I make an individual setting for a client (adding a path to save)
    and I save it.
    from the web interface (no folder configured).

  • (hyper-v 2016 client urbackup plugins) when that hyper-v client
    is installed on the host and I make an image backup of the Vm client
    [ Backup of system reserved partition (SYSVOL) failed. Failed to save
    however, there is a checkpoint creation that was created by urbackup in
    the hyper-v manager

what did i do wrong ?
