Binary Backup in Dgraph

I am currently using DGraph cloud, my use case is to archive the data present in DGraph. I am able to export the data using export command. While referring the documentation I came across binary backups. Does the cloud instance support binay backups? If yes can help me out with python code snippet to perform the perform.
Thanks in advance!!

Yes. As far as I know the Cloud backups are binary backups.

Not sure what you mean. Can you explain?
