For cloud backup of anything, even moderate quantities of documents, i've never trusted Google in the least despite its size, even aside from its grotesquely parasitic "privacy" policies (a complete joke of a word for anything to do with that company). Now there's crap like this event, affecting who knows how many customers.
Basically, a 3-2-1 strategy is also a good idea. A physical HD/SSD in a safe place for one, along with synced working copies of documents in a machine you're using, and then in case of deep catastrophe, some sort of cloud solution, preferably one that's zero knowledge, either because it has it baked in or from using something like cryptomator.
So far I've tried several online backup services and maybe unexpectedly, the most easy to work with and simply functional across multiple machines and several external drives has been SpiderOak. Its desktop interface is shit, but the overall service is easy to use and has never failed me one so far, and it constantly, incrementally conducts deduplicated backups of even minor file/folder changes as long as it's running. As a second option, Arq has been nice too, though its UI is also rather clumsy.
