I have installed the urbackup client on a another server with debian (version 2.2.6)
I have setup a dir to backup, but i have an error and backup stop with this message :

Error while getting files in folder “/home/admin-sbs”. User may not have permissions to access this folder.

I have setup the dir on urbackup client with root because on normal user i have an error permission pw_change.txt
