Tricky Quoting Issue in BASH

I'd like to run an rsync command to do backups, with an exclude
pattern. I can build what looks like a perfectly good command, echo
it, then run it. But the exclude pattern is ignored. However, if I
copy the echoed command line and execute it directly, it works and the
exclude pattern is respected.

Something like:

    # options to feed to rsync

    opts="-va --exclude '*~' --delete --delete-excluded"


    cmd="rsync $opts $internal$back/ $external$back"

    echo $cmd
