Cloud drives are a handy form of secondary backup, IF you secure the contents with a tool like Cryptomator. I backup my content to a local NAS which one-way syncs nightly to an external drive attached to Raspberry Pi at my office and a cryptomator Dropbox, that in turn one way syncs to cryptomator Google Drive. I also manually encrypt and upload important documents to Proton Drive and Mega as cold storage.
