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.
Is there cheap cloud backup that will integrate directly with Windows Server Backup?
That's essentially what my WSE 2016 box is. I just think that an online backup would be a good idea
