As usual for most backup tools it does not include cloud API access and relies upon enumerated local folder mirrored to the cloud by local clients that can be accessed by ransomware so is pointless at backing up in the event of ransomware attack. Ok it does have FTPS support but that is an expensive option, most web hosting options while they do offer FTP they do not normally offer FTPS and it is usually against their terms to use it for private storage FTP server instead of a web server… You could rent a dedicated virtual server but it’s unlikely you’ll be relying upon cheap/giveaways if you can afford to rent a dedicated virtual server to get FTPS access to secure online storage.
