What S3, Backblaze B2, Wasabi and Cloudflare R2 charge when your data leaves their network. Worked out for a 10 TB and a 100 TB restore, with what a flat-rate storage server changes.
Quick answer
What are cloud storage egress fees, and how do I avoid them?
Cloud storage egress fees are charges for data that leaves a provider's network, billed per GB downloaded. On 2 November 2026, Amazon S3 charged $0.09/GB for the first 10 TB a month, so a 10 TB restore cost $891. Flat-rate capacity avoids them: Basalthold storage servers include a monthly traffic allowance, from $110.99, crypto only, no KYC.
| Amazon S3, US East | $0.09/GB for the first 10 TB of a month, $0.085 for the next 40 TB, $0.07 for the next 100 TB, $0.05 above 150 TB; the first 100 GB a month are free |
|---|---|
| Backblaze B2 | $6.95 per TB stored per 30 days; downloads free up to 3× your average stored data, then $0.01/GB |
| Wasabi | $7.99 per TB a month; no egress fee while monthly downloads stay at or below your stored data; 90-day minimum; 1 TB minimum charge |
| Cloudflare R2 | $0.015 per GB-month stored; no egress charge; write and read operations are billed |
| Hetzner Storage Box | Traffic listed as unlimited; $2.27 to $3.58 per TB a month; no crypto payment |
| Basalthold holds | Every server has a 1 Gbit/s port with a monthly traffic allowance (Hold 24 40 TB, Hold 40 60 TB, Hold 100 120 TB, Hold 160 200 TB), one dedicated IPv4 address and an IPv6 /64; going past the allowance never triggers an automatic bill |
| Uploads | AWS lists data transfer in from the internet at $0.000 per GB |

Decimal units: 1 TB = 1,000 GB. AWS tier limits are used as AWS lists them (10 TB = 10,240 GB, 50 TB = 51,200 GB). Prices from each provider's pricing page and the AWS Price List API, read on 2 November 2026.
An egress fee is a price per GB for data that leaves the provider's network for the internet.
Amazon S3 bills egress in tiers. In US East, the first 10 TB of a month cost $0.09/GB and the next 40 TB $0.085. The next 100 TB cost $0.07, and anything above 150 TB $0.05. The first 100 GB each month are free, counted across all AWS services.
Storage is cheap by comparison. S3 Standard costs $0.023 per GB-month for the first 50 TB, so 10 TB stored costs about $230 a month. Downloading those 10 TB once costs $891, almost four months of storage. The storage side for every provider at one capacity is on the 100 TB cloud cost page.
Because you download a backup on the worst day: after a disk failure, a ransomware attack or a deleted bucket.
You pay egress exactly when you need your data most.
The same fee applies to restore tests and to a second copy kept elsewhere. A monthly 1 TB restore test from S3 costs $81 after the free 100 GB. Copying 50 TB out of S3 once costs $4,292.70. The offsite copy of a NAS raises the same question; see offsite backup for a NAS.
Several providers drop the per-GB price, then set a rule somewhere else.
Each model moves the cost: a higher storage price, a download ratio, a minimum term or request fees. The full bill side by side is on our B2 and Wasabi comparison.
It replaces the per-GB price with a port and a monthly allowance. You pay the same rent whether you download 1 TB or the whole array.
Every server has a 1 Gbit/s port with a monthly traffic allowance (Hold 24 40 TB, Hold 40 60 TB, Hold 100 120 TB, Hold 160 200 TB), one dedicated IPv4 address and an IPv6 /64; going past the allowance never triggers an automatic bill.
The port sets the real limit. A 1 Gbit/s link moves at most 125 MB/s, about 324 TB in 30 days in one direction. A full 100 TB restore takes about 9 days and 6 hours at line rate; 10 TB takes about 22 hours.
A flat-rate server turns egress into a question of time, not money.
Of 23 storage-server sellers Basalthold checked on 2 November 2026, 16 accepted crypto. At the no-KYC crypto hosts, a server of 16 TB or more cost a median $9.50 per raw TB a month. Basalthold Hold 160 works out at $3.50/TB and Hold 100 at $3.77/TB. The survey is on the price-per-TB page.
The trade-off is work. You build the array, run the software and keep a second copy: A storage server is not a backup of itself: we keep no copy of your data anywhere else, so a second copy in another place stays your job. An S3 endpoint on your own server is covered in self-hosted S3 storage.
Plan the restore before the disaster, and price it.
Each hold is a whole machine with its own drives and a fixed monthly traffic allowance. Longer terms and the three cities are on the price list.

In every plan: Blank data drives · Encryption keys stay yours · Dedicated IPv4 · No logs · No KYC · No setup fee
No. You pay one price per hold for 30 days or a longer term, and traffic is not billed per GB. Every server has a 1 Gbit/s port with a monthly traffic allowance (Hold 24 40 TB, Hold 40 60 TB, Hold 100 120 TB, Hold 160 200 TB), one dedicated IPv4 address and an IPv6 /64; going past the allowance never triggers an automatic bill. Holds start at $110.99 per 30 days.
Usually yes. AWS lists data transfer in from the internet at $0.000 per GB. The cost sits on the way out, plus request fees where a provider charges them, as Cloudflare R2 does.
About $7,812 in egress at US East rates read on 2 November 2026, after the free 100 GB. Storage and requests come on top. The same restore from B2 or Wasabi costs nothing in egress when you store at least as much as you download.
About 9 days and 6 hours at a full 1 Gbit/s, since the port moves at most 125 MB/s. Busy disks or a slow receiving end stretch that time. Every hold has a 1 Gbit/s port.
Yes. Basalthold takes BTC, USDT, USDC, ETH, SOL, LTC, with a minimum top-up of $25. No KYC: no ID, no selfie, no documents, no card and no phone number, at any point. Setup takes 72 hours at the most after your payment is confirmed.
