Cloud backup & egress cost calculator
Compare cloud backup cost across Amazon S3, Azure, Google Cloud, and ZeroVault — including what a full ransomware restore costs in egress, and how ZeroVault's zero-egress model changes the answer. Runs in your browser.
Prices are commonly-published list rates reviewed 2026-07 and are editable — clouds price per region/tier and change often, so verify against your own bill. ZeroVault defaults reflect IDrive e2 MSP/reseller storage pricing (~$4.1/TiB-month) with $0 egress. Egress here uses a flat effective rate; tiered discounts on very large volumes make the real figure slightly lower on paid clouds.

Provider comparison
How cloud backup and egress cost works
Cloud backup cost has two parts — storage (priced per TiB-month, multiplied by how many copies you keep) and egress, the fee to download your data back. Amazon S3, Azure, and Google Cloud charge roughly $0.05–$0.12 per GB to retrieve. ZeroVault charges no egress fees. A restore is an egress event, so the provider that looks cheapest to store on can be the most expensive to recover from.
The moment egress cost matters most is a ransomware recovery, when you may pull back your entire fleet at once — 100 TiB of egress from Amazon S3 or Azure can cost thousands of dollars, billed exactly when you are already in crisis. This calculator makes that one-time restore cost the headline and compares all four providers side by side, highlighting ZeroVault's zero-egress advantage. It is a planning estimate: all prices are editable and dated.
Example: 50 TiB of backups, two copies, on Amazon S3 at $23.6/TiB-month and $0.09/GB egress. A full ransomware restore of all 50 TiB egresses about $4,600; the same restore on ZeroVault costs $0 in egress.

Frequently asked questions
How much does it cost to restore backups from the cloud?
It depends on egress. Downloading data back costs roughly $0.05–$0.12 per GB on Amazon S3, Azure, and Google Cloud, but $0 on ZeroVault. Storage is separate — about $4–$24 per TiB per month depending on provider and tier.
Why is a ransomware restore so expensive on some clouds?
Because you egress a huge amount of data at once. Backup storage looks cheap month to month, but a full recovery downloads 100% of your data, and paid egress is charged on all of it in the same month — the worst possible time. ZeroVault removes that spike entirely with zero egress fees.
Which cloud is cheapest for backups?
For recovery, ZeroVault avoids the restore bill that makes hyperscalers costly to pull from — $0 egress on a full ransomware restore. For storage alone, ZeroVault is also among the lowest per TiB. This tool prices both storage and restore so the verdict accounts for recovery, not just parking data.
Are these prices accurate?
They are commonly-published list rates reviewed in July 2026 and are fully editable — cloud pricing varies by region and tier and changes often, so enter your own rates for an accurate figure. Egress here uses a flat effective rate; very large restores get small tiered discounts on paid clouds.
