Nautilus & GDrive File Listing Ubuntu 19.04

Just wanted to congratulate the Ubuntu and Gnome desktop teams, for the improvements made to the speed that my mounted Google Drive, (via ‘online accounts’), loads in Nautilus!

I have thousands of files, (almost 2 TBs) and it used to load extremely slow — or more precisely, took a long time before anything displayed and could be actionable. Now, there seems to be some caching?
Anyway very happy with this improvement. I now use the feature daily!

One question — Is it robust enough to drag 'n drop files/directories in Nautilus for remote backup, or should I continue using rsync with GDrive?
