Services such as Dropbox, OneDrive, iDrive etc are regarded as network storage, they're OK for calibre library backup storage, but they're NOT OK for active calibre library storage.

Bad idea. You have to make a backup in order to allow the cloud storage access to your library and since you already have to make a backup, may as well just go with that backup as once you let the cloud storage access to the backup, it's most likely a goner.
