This is the full reference behind the family-archive backup series, beginning with the hub: a complete list of the cloud and self-hosted backup providers worth knowing in 2026, from the cheap rent-by-the-terabyte services a family might actually use, through the self-hosted and ZFS-native options, to the enterprise and cold-storage tiers that exist but aren’t aimed at home archivists.
It is deliberately comprehensive and a little technical, because that is what a reference is for. If you only want the handful that suit a family archive, the main articles make those picks for you and explain them in plain language, with the cloud guide covering these providers in prose; this page is here for when you want the whole field in one place.
Prices are 2026 guide figures and the market moves quickly, so treat them as the shape of the costs rather than a live quote, and verify directly with the provider before committing. “Backs up a NAS” and “ZFS-native” are the two columns that matter most for keeping a NAS copy in sync off-site.
A note on Synology: it appears below as a compatible target for a few services, so it’s worth being plain. I can no longer recommend Synology, for reasons set out in a number of posts you’ll find online; where it shows up here, that’s a statement of compatibility, not an endorsement.
Backup providers, A to Z
Two columns are new and worth a word. Every service below encrypts your data both at rest and in transit, so the column that matters is who holds the key: the provider (who can read it, or be compelled to), or only you (zero-knowledge). And sync or backup matters just as much — a sync service mirrors changes both ways, so a deletion propagates, while a backup keeps versions you can return to; raw storage is either, depending on the tool you point at it. The article Keeping your family archive out of the wrong hands works through what these mean.
