Yes, "bare" single-user VM with no publicly available services is something you barely have to manage if at all. It's not like it's bare metal where you have to deal with it failing. 4 rented/hosted offsite backups seems overkill. But I can understand that the number of on-site backups doesn't really matter for the safety, because there are several event types that can destroy them all at once. 1 owned backup device in a different location seems perfectly reasonable. Hosted stuff can easily go away if you stop being able to pay for it or lose access, for any reason. Anyway, of course some "I trust backblaze with everything, incl. quality of their backup software" setup, will be much less complicated and will require much less knowledge.
