@Anonymous Thank you for your time and patience.
There are not a lot of tools that support OpenStack Swift (the foundation of RAX Cloud Files). As this is a small amount of data (500GB), I would recommend using RackSpace’s recommended tool CyberDuck. It can copy and synchronize between Cloud Files and Blob Storage.
Reference / recommendation from Rackspace - Other tools and applications for Cloud Files — Rackspace Cloud Files v1.0 v1. documentation
Please let us know if you have any further queries. I’m happy to assist you further.
