I will at my two cents: I've been very happily using Restic and B2 for a long time. It's cheaper than the unlimited service given I have ~600GB stored. Plus, it's a "real" backup: on-going series of snapshots, older files are not replaced when a new back up is made, I can restore from as many points in time that I want to store, and I don't have to worry about Backblaze deleting anything due to inactivity. One underrated feature of Restic is tagging, which lets you identify a collection of snapshots. I can point multiple separate backups and devices to the same repository tracked with tags; thus, I de-dupe across all of them.
