Is there anyway that you could add in the capability to actually see what files have been copied or modified so we can check that it has worked properly?
Before trying I would use following command /usr/local/bin/rsync -avE -progress -delete -exclude-from= /home /Volume/home
With this I could see what happened and could watch the progress. I see the lovely progress bar but would like to be able to delete old files (does this happen with "Unidirectional Backup")? And see what was copied or updated.
