As I'm in a similar situation with Crashplan I've researched this a bit more (have just under 2TB so was originally just going to pay up for the business plan so cost wasn't to high). VPS's are probably a no go as they have all moved to SSD's with low sized volumes. Even with Digital Ocean where you can add block storage you are looking at $100 for a week for 4TB + compute and bandwidth. AWS you are looking at $368+ just on data egress. hetzner.com server auctions look the best option. Current cheapest is €31.93 per month for a Intel Core i7-3770 (CPU-B 9445) with 2x 3 TB drives and 16 GB. Probably simple enough to use lvm and jbod on the drives to give a single 6tb volume. No egress charges but reading they throttle if you go over 20,000GB a month so a non issue. No setup fees/contract on the auctions although reading I think it's 30 days/1 month notice to cancel so would need to cancel as soon as ordered. My plan is to probably move to Git Annex https://git-annex.branchable.com/ https://git-annex.branchable.com/, use my local NAS as the main backup, maintain a copy of media / photos / docs in Backblaze and duplicate files I can't afford to lose to S3 also. Looks simple enough with Git-annex and lets me maintain multiple copies based on cost / importance.
