Again, I'd like to do a partial backup. Let's say I export 10GB of titles at time. Once the first 10GB of data is safely backed up in the cloud, I can delete those titles from my calibre library and then move on the the next batch. How can I do such a partial backup while keeping all metadata.
Create a new, empty library (keeping the structure of your old library). Copy the books you want to back up to the new library. Zip the new library folder up and upload to the cloud. Delete the copied books from the old library.

When restoring, extract the second library from the .zip file. Point Calibre to it (switch/create library -> use the existing library at the new location). Copy the books there to your main library. Delete the second library.
