Rsync delete orphan files from target only - no copy

Calling rsync in the following way, using --existing, --ignore-existing and --delete allows the following:

• Files at target that do not exist at source will be deleted.
• Skipping all file copy operations from source to target.

$ rsync \
    --delete \
    --existing \
    --ignore-existing \
    --itemize-changes \
    --progress \
    --recursive \
      /path/to/source/ /path/to/target
