The packaging option is more specific to moving a project from PC to PC. Any good backup tool will give you the suitable archive and backup needed, or use a version control tool.
If you organise your projects into sub-folders for the Library files and Scene files eg ..\mydocuments\Lumion\Library\ProjectXYZ and ..\mydocuments\Lumion\Scene\ProjectXYZ plus use another single project folder for all your input and output resources, then its not too hard to zip or RAR up or use backup tools to backup or archive or restore from.
All you need to do manually is maintain the sub-folders (10 seconds a day) to move the files to respective places.
