It didn't do this before. Why will it not create a directory? But wait! The directory already exists.

bmike1@c521 ~ $ rsync -aWq --progress --delete-before --compress-level=5 /home/bmike1/Documents /media/bmike1/"USB DISK"/

rsync: mkdir "/media/bmike1/USB DISK" failed: Permission denied (13)

In rsync, incremental recursion, refers to memory saving technique where it starts transferring files while only reading in a subset of the list of files that will be transferred.
If you use --delete-before rsync will have to know the whole list of files so it will know what to delete, so naturally incremental recursion gets turned off because leaving it on conflicts with that you have asked it to do.

Thanks for sharing with me about --delete-before. In my subsequent
investigation into it's use I found the manpage says that using that
option disables 'incremental recursion'. What is 'incremental
recurssion'? I assume that I will still be able to backup lower level
directories.

Some options require rsync to know the full file list, so
these
options disable the incremental recursion mode. These
include:
--delete-before, --delete-after, --prune-empty-dirs,
and
--delay-updates. Because of this, the default delete
mode when
you specify --delete is now --delete-during when both
ends of
the connection are at least 3.0.0 (use --del or
--delete-during
to request this improved deletion mode explicitly).
See also
the --delete-delay option that is a better choice
than using
--delete-after.

Mike,
you can have rsync do the deletes prior to copying files over
--delete-before receiver deletes before xfer, not
during
You can also delete the excluded files if you use some form of
the exclude command,
--delete-excluded also delete excluded files from
dest dirs
