backup & DR · distributed S3 · no egress

Restore it as often as you like.
The bill does not move.

Most disaster recovery plans go untested, and the reason is usually the read charge: every rehearsal costs real money to pull the data back. Restores here are free and uncapped, so the plan you signed off on can be the plan you have actually run. Immutable, versioned, and held on storage you compose yourself — with no single datacenter to lose.

The restore test

A backup you can’t afford to test isn’t a DR plan.

DR is mostly cold data held a long time — then a full restore when something breaks. On hyperscalers, that restore is a four-figure egress bill. On XNS it’s $0, every time, with no ratio cap.

Storage (50,000 GB)~$300/mo*~$1,178/mo

Run the drill weeklyStill $0Still metered

* 50,000 GB at $0.006/GB-mo. The erasure-coding parity that protects your data is included in that rate, not billed on top. Hyperscaler storage and egress figures are AWS S3 list pricing for the same volume, checked 2026-08-19; restore egress is the published per-GB rate with no free tier applied.

restic — change one endpoint
# offsite copy, the same tool you already use

Your metadata

They encrypt your files. They keep your metadata. We keep neither.

Who downloads what, from where, how often — that record is worth more than the data, and 61% of government data demands target it. Every other cloud holds yours. XNS has no access to your data or your metadata. Nobody does.

Virtual Private Datacenter

Compose where your backups live.

Choose geography, durability, and jurisdiction for your offsite copy. A VPD is to storage what a VPC is to compute — the network is raw material; the VPD is what you ship on.

MSPs need per-tenant isolation. IT admins need data residency they can defend. Start from the live map and build a provider set by the dimensions that matter — no other cloud hands you the architect's table.

Your tools

Change the endpoint. Keep everything else.

Backup tools speak S3. Point them at your own XNS endpoint — no custom integration, no lock-in. Then add the controls that make an offsite copy trustworthy.

restic

Point the reference backup tool at our S3 gateway for encrypted, deduplicated offsite copies. Standard S3 backend — nothing custom to maintain.

rclone · kopia · duplicati

Any S3-compatible backup target works. Standard API, standard SDKs — migrate in, migrate out, no lock-in.

Object Lock & WORM

Compliance and governance retention plus legal hold, enforced per tenant at the database key rather than account-wide. A compliance-mode retention period cannot be shortened or lifted by any credential, including yours — which is what stops a stolen key deleting the backups. The exact scope →

live

Per-tenant IAM

Scoped users, roles, and policies via the standard AWS IAM query API — give every client or site its own isolated, least-privilege keys.

live

30-day minimum retention

Low 30-day floor, not 90. No 90-day minimum-duration charge on data you no longer need.

live

Unlimited free restores

Egress is never metered, so a full DR drill costs $0 — run it weekly, not once a year because the restore bill scares you.

How we compare

Cheapest to hold. Free to restore.

For backup and DR, storage price and restore cost matter more than feature checklists.

XNS is billed per TB of your data — the erasure-coding parity that protects it is included in the rate, not charged on top. Competitor figures from each vendor's own pricing page: AWS 2026-08-19, Wasabi 2026-08-19 ($7.99/TB since 2026-07-01), Backblaze B2 2026-09-04. How the egress column works →

Two of those pages are worth ten minutes before you move production backups: what works and what does not for backup — every S3 gap sorted by whether it touches a backup workflow — and how egress pricing actually works, including what our $0 covers and what it does not.

the rest of the evidence

Everything else you would check before trusting us with a backup

Every claim on this page has a page behind it. None of them are marketing summaries — they are the working documents, including the parts that do not favor us.

A tested restic setup, end to end Immutable retention configured, a restore actually performed and verified, and the two places the combination bites. Every command was run before it was written down. What works and what does not Every gap in our S3 support, sorted by whether it touches a backup workflow. Read this before you move anything. Object Lock, at its real scope Compliance and governance retention, legal hold, and why per-tenant enforcement is the part that matters. How the $0 restore works What no egress charge covers, what it does not, and the pricing terms it is scoped to. The conformance results The full ceph/s3-tests run published line by line, including every test we do not pass. What it costs against the alternatives Storage and restore side by side with the clouds you would otherwise be paying. What your own numbers cost Put your data size, retention and restore volume in and see the monthly bill against five other vendors. What runs, and how you would leave The workloads we are built for, the differences to settle during evaluation, and the exit path with commands. What a security review asks Encryption, the durability math, identity and access, the audit log, and the line between what you operate and what we do. The tools you already run restic, rclone, kopia, duplicati, Veeam and thirty more, each with its own setup page. Stand one up Zero to a claimed Relayer with working S3 storage. Copy-paste, about ten minutes, Docker the only prerequisite.
