I am completely new at this just tried OMV@192.168.2.101:://D/Documents
Please wait, syncing <OMV@192.168.2.101:://D/Documents> to </srv/dev-disk-by-label-SSD_T5/test> ...
ERROR: The remote path must start with a module name not a /
of course I do not know how to configure Rsync , but should I use the plugin Remote Mount? any input would be appreciated.
