+ Provider comparison
Compare immutable
backup providers.
If you're evaluating where to send your immutable backups, this page is the cheat-sheet. Five providers, twelve dimensions that actually matter, public-pricing-page sources. We point out where competitors win — there's no version of this we can publish dishonestly.
Pricing and specs retrieved May 2026 from each vendor's public documentation. Vendor positions move; if you're seeing this in 2027 and a row looks wrong, email us.
+ Three questions that matter
Most provider comparisons drown in features. The right provider for you usually falls out of three buyer questions.
01 / Jurisdiction
Where does your data legally need to live?
If "outside the US, outside EU member states, EEA-aligned" is a hard requirement (regulated SMB, EU government contractor, leaving US-controlled SaaS): only one credible option exists. If "EU is fine" is enough, your set widens.
02 / Egress
How big is your monthly egress bill today?
Hyperscalers charge €70–90 per TB egressed. A 50 TB ransomware restore from S3 Glacier Deep Archive is a five-figure bill. Flat-rate providers (Wasabi, B2, Impossible, Recover) eliminate that line item.
03 / Air-gap
Do you need air-gapped recovery, or is Object Lock enough?
Object Lock prevents ransomware from deleting backups — every provider here supports it. Air-gap goes further: credentials and network paths separated from primary backup, so a fully compromised admin domain can't reach the recovery copy. This is the only tier-shaped axis between providers in the table.
+ Side by side
Twelve dimensions. Recover wins on some, loses on others.

+ Concrete pricing — 25 TB stored, one full restore per year
Apples-to-apples scenario: 25 TB Veeam-style backup repository, monthly storage, one full annual restore (25 TB egress) — the kind of bill you'd actually see if a ransomware drill went all the way through.
Scenario
25 TB stored · 25 TB annual egress · standard API call volume
| Provider | Monthly storage | Full restore (annual) | Lock-in |
|---|---|---|---|
| AWS S3 Glacier Deep Archive | ~€25 storage | ~€1,800 egress + retrieval | 180-day minimum |
| Wasabi Hot Storage | ~€175 | €0 egress | 90-day minimum |
| Backblaze B2 | ~€100 | €0 (within 3× tier) | 1 day |
| Impossible Cloud PAYG | ~€200 | €0 egress | None |
| Recover Archive · Pro tier | €349 | €0 egress, €0 API | None · monthly billing |
Recover Archive prices higher per byte. The premium buys: Iceland jurisdiction outside US and EU member states, hash-chained audit evidence bundled, an air-gapped recovery tier (Vault), and a contractually capped sub-processor list. If you don't need any of that, the table above shows you cheaper options — and we mean it.
+ When to pick someone else
The most useful page on the internet for you is one that tells you when not to buy from us. Here's that page.
Pick AWS / Azure if
You already operate deep on a hyperscaler, your backup software is a hyperscaler-native service (AWS Backup, Azure Backup), and jurisdiction isn't a written requirement. Hyperscaler ecosystem gravity is real.
Pick Wasabi or Backblaze if
Cheapest-S3-on-the-internet is the spec, US ownership is acceptable, and your ransomware drill stops at "Object Lock prevents deletion." Their flat-rate model is genuinely good economics for backup workloads.
Pick Impossible Cloud if
EU-member-state jurisdiction is sufficient (you're a German firm storing German citizen data and "Germany or anywhere in EU" is fine), you want a partner-channel motion, and you don't need an air-gapped tier.
Pick recover.is if
Iceland-resident-and-EEA-aligned-but-non-EU is a written requirement (regulated SMB, EU government contractor, sovereignty migration), audit-grade evidence is a recurring auditor ask, or your DR plan requires an air-gapped recovery tier separate from primary backups. Otherwise — see the rows above.
+ Still evaluating?
Send us your current cloud bill and we'll do the math.
Forward the latest invoice from your existing provider — AWS, Wasabi, B2, anyone — and we'll send back the equivalent Recover bill, plus a one-page TCO that includes restore cost. No sales call, no obligation.
