Jupyter notebooks deleted in Paperspace

I had made several copies of the Jupyter notebooks from the lessons to play around with the code. Today when I logged in, all my copies had been removed. How do I save my Jupyter notebooks to ensure that they are not overwritten/deleted whenever I do an update?

I am using Gradient Notebooks in Paperspace.

This happened to me as well. Contacted Paperspace, but wasn’t fixed. I guess we just have to remember to backup those notebooks locally each time we finish
