Comments about using rdflib.js to backup and migrate ldp server content

I would like to use rdflib.js to recursively create a backup of a linked data platform server.

 - I managed to get the child containers with the sixth experiment with rdflib.js
- I need to also find any contained RDF files (some other term in the ldp vocab.)
 - I need to also pull all the content for each ldp container)

- Then i need to do http requests to ldp server of my choice.
- and rewrite the ldp server uris appropriately (move from one content to another)
