If you're fine with self hosting, you can just self host it and backup your local drives to a remote location. That's what I do.

For backup software, I use Duplicacy. But Veeam, Borg, etc.. would work just fine. For images, since they're just static files and you don't really need a version history, you could get away with a scheduled rsync job. Though, technically that leaves you more at risk of ransomeware or something that overwrites your data.

For remote storage, I'd first consider a Hetzner storage box since they are flat-rate pricing and pretty dang cheap at $13/mo for 5TB. You might also consider StorJ, B2, S3, etc... I'd just stay away from any lesser known ultra-cheap storage providers.
