In that case, let's then go on to the main issue: how do we setup a cloud backup of the calibre library?

Do not put your calibre library on a networked drive.

A filesystem is a complex beast. Most network filesystems lack various filesystem features that calibre uses. Some don’t support file locking, some don’t support hardlinking, some are just flaky. Additionally, calibre is a single user application, if you accidentally run two copies of calibre on the same networked library, bad things will happen. Finally, different OSes impose different limitations on filesystems, so if you share your networked drive across OSes, once again, bad things will happen.

Even with these tools there is danger of data corruption/loss, so only do this if you are willing to live with that risk. In particular, be aware that Google Drive is incompatible with calibre, if you put your calibre library in Google Drive, you will suffer data loss
