I have discovered an issue if yuo wish to use the below method to backup your .kodi folder.
Once OpenVPN is installed the backup seems to complete but reports an error with regards to permissions of the openvpn script. Perhaps @sam_nazarko could kindly advise on how to allow the permissions or alter them.
I have a feeling that it is making a backup of the .kodi folder but unable to backup the openvpn part because of the permissions of the script.
I can post back with what putty spits out tomorrow.
