One of <source> or <destination> must be of S3 format, the other a local path.
Reminders:
* An S3 formatted item with bucket 'mybucket' and prefix 'mypre' looks like:
mybucket:mypre/some/key/name
* Local paths should always use forward slashes '/' even on Windows
* Whether you use a trailing slash on the source path makes a difference.
* For examples see README.
