Is there cheap cloud backup that will integrate directly with Windows Server Backup?

I've been thinking about backing up my home server to the cloud. The obvious choice is Azure but given the amount of data, it's cheaper to buy external HDDs and rotate them, which is what I do. I have perhaps 5 TB of data which includes backups of my PCs, and I do want those backups in the cloud. It excludes WSUS data, which can safely not be backed up. Even £1 / TB a month seems not cost-effective with HDDs so cheap.

Not buy a 2 or 4 disk Nas box and use it for backups, music, pics and movies? Lowish energy, quiet and almost invisible but locally manageable.

That's essentially what my WSE 2016 box is. I just think that an online backup would be a good idea

What about a second 2/4/5 bay nas (5TB is tiny in grand scheme of things) at your parents house (assuming this is an option), with remote synchronisation between your home nas and the one at your parents.
