I changed the path the default path of the Archive Settings ( RME > Admin > Config Mgmt > Archive Mgmt > Archive Settings) with another path with casuser permission.
I stopped the ConfigMgmtServer process e retarted it after changing.
During a resotore backup all configuration files are losted.
This mean that I have to put my new path into AllowedFolders.properties file?
Thanks a lot!
