6 Backblaze B2 Hidden Costs Beyond the List Price

Beyond the listed price, Backblaze B2 has at least 6 documented hidden costs that can significantly increase total cost of ownership.

Watch for 6 hidden costs
  • Egress / Download Fees Above Free Threshold $0.01/GB above free threshold
    high 3 sources
    Reddit "Egress above 3x monthly average storage is also free through many CDN and compute partners; otherwise, overage is billed at $0.01 per GB. That monthly average gets a lot of people in trouble."
    Reddit "Be VERY careful with BackBlaze pricing. Their pricing for us JUST to do the _directory listing_ needed for us to do our nightly backups was $3000/mo. I confirmed this with their support and dropped them on the spot."
    Reddit "Yes, the 3x was related to free egress but that wasn't clear in my comment. What I wanted to state is that if you have a busy streaming app this model might not be ideal as egress can easily exceed that threshold"
  • API Transaction Fees 5-15% of storage costs
    medium 2 sources
    Reddit "They also charge a very nominal amount for certain API calls beyond certain limits (if your usage is below that limit the calls are free). See https://www.backblaze.com/cloud-storage/transaction-pricing"
    Reddit "storage charges apply to all data after the first 10GB in your account at the rate of $0.006/GB/month"
  • Byte-Hour Billing Can Surprise New Users varies by upload timing
    low 2 sources
    Reddit "Backblaze charges by the byte-hour, so even if you uploaded 1TB today, your monthly average storage would not be 1TB yet, because it's only been a single day."
    Reddit "I'm looking at https://www.backblaze.com/cloud-storage/pricing and it says 'starts at $6/TB/month', which confuses me - if I put 10 GB there, will I pay $6 anyway, or 6 cents"
  • NAS / Business Plan Upgrade Required $6/TB/month for NAS vs $99/year unlimited for PC
    medium 2 sources
    Reddit "BackBlaze use to be a good option. But if you use a NAS for Plex it jumps up to a Business plan with becomes a lot more expensive."
    Reddit "circumvent, or attempt to circumvent, storage space limits or pricing. use the Backblaze system in a manner inconsistent with its intended manner or purpose."
  • Monthly Average Storage Billing Complexity $6/TB/month on actual stored average
    medium 2 sources
    Reddit "Backblaze charges by the byte-hour, so even if you uploaded 1TB today, your monthly average storage would not be 1TB yet, because it's only been a single day."
    Reddit "Full disclosure, in case you don't look at my profile - I'm a Backblaze employee. Backblaze charges per byte-hour, and the first 10 GB is always free, so for 100 GB for a month, you'd pay 0.09 * $6 = $0.54 for the storage."
  • GST/VAT Surcharges for Non-US Users 10-30% of license costs
    low 2 sources
    Reddit "That's way cheaper than mine. Naka-Backblaze ako pero ang mahal niya at 588 for month for 1.5TB. Naka-USD pricing pa ako kaya mas mahal minsan."
    Reddit "I'm in the same situation... factoring in GST, Backblaze is no longer as affordable as I had hoped."

How to Negotiate Backblaze B2 Pricing

Negotiation Playbook 7 tactics
Use Cloudflare CDN for Free Egress high success

Backblaze partners with Cloudflare (and other CDN/compute partners) to offer free egress when traffic flows through their network. Routing your downloads through Cloudflare R2 or Cloudflare CDN can eliminate egress charges entirely for high-bandwidth workloads.

reddit (multiple users)
Set Price Caps to Avoid Surprise Bills high success

Backblaze allows you to set caps on downloads, storage, and API call classes so you don't get surprise charges. Configure these immediately after account creation to protect against runaway egress or transaction costs.

Backblaze B2 Pricing FAQ

01 What is the cheapest paid plan?

The B2 Cloud Storage plan is the cheapest paid plan at $6.95 per TB per month.

02 What are the pricing options for B2 Reserve?

B2 Reserve has several annual pricing options: $19,500.00 per year, $75,600.00 per year, $52,395.00 per year, and $69,000.00 per year.

03 Does Backblaze B2 offer a free plan?

Backblaze B2 does not offer a free plan.

04 How does Backblaze B2 pricing actually work — is it really $6/TB/month?

Backblaze B2 Cloud Storage charges $0.006/GB/month (which equals $6/TB/month), billed by the byte-hour on actual data stored. The first 10GB is always free. There is no minimum monthly charge — if you store 100GB, you pay roughly $0.54/month. Downloads (egress) up to 3× your monthly average stored data are free; beyond that, egress costs $0.01/GB. API transactions beyond daily free allowances also incur small fees.

05 Can I use Backblaze B2 for NAS backup?

Yes, but you must use the B2 Cloud Storage pay-per-TB plan ($6/TB/month) rather than the consumer Personal Backup unlimited plan ($99/year). The unlimited personal plan only covers computers with directly attached storage. NAS users typically use rclone, Duplicati, or their NAS OS's built-in cloud sync to push data to B2.

06 Is egress really free on Backblaze B2?

Partially. Egress is free up to 3× your monthly average stored data each month, and also free when routed through Cloudflare and other CDN/compute partners. Downloads exceeding the 3× threshold are billed at $0.01/GB. For backup use cases with rare restores, egress is effectively free. For streaming or high-download applications, costs can add up quickly.

07 What happens if I upload a large amount of data suddenly — will my bill spike immediately?

Backblaze charges by the byte-hour, so if you upload 1TB on the last day of the month, your charge for that month will be very small (only a few hours of storage). However, your monthly average stored data will be higher going forward, affecting your free egress threshold. New users often underestimate this billing model.

08 Does Backblaze B2 have any restrictions on use case?

Yes. Backblaze's Terms of Service prohibit circumventing storage limits or pricing (e.g., using Docker to back up NAS storage through the personal unlimited plan), and using the service in a manner inconsistent with its intended purpose. Violations can result in account termination.

09 How does Backblaze B2 Cloud Storage pricing actually work?

Backblaze B2 charges $6.95/TB/month (approximately $0.006/GB/month) for the B2 Cloud Storage plan, billed by byte-hour (monthly average stored). The first 10GB is always free. Egress (downloads) is free up to 3x your monthly average stored data through CDN/compute partners, or $0.01/GB for overages. There are also API transaction fees for certain call classes beyond daily free limits.

10 Is Backblaze B2 truly cheaper than AWS S3?

For storage and egress, yes — B2 Cloud Storage at $6.95/TB/month compares favorably to AWS S3's $23/TB/month. AWS Glacier is cheaper ($1-3.6/TB/month) for pure storage but has high retrieval costs ($9/TB). The comparison depends heavily on your download/egress patterns.

11 Does Backblaze B2 charge for downloads?

Downloads up to 3x your monthly average stored data are free when using Cloudflare or other CDN/compute partners in the bandwidth alliance. Otherwise, egress above that threshold is $0.01/GB. High-traffic applications should route through Cloudflare to eliminate egress costs entirely.

12 What's the difference between Backblaze Personal Backup and B2 Cloud Storage?

Backblaze Personal Backup is an unlimited computer backup service at $99/year for a single computer. B2 Cloud Storage is a pay-as-you-go S3-compatible object storage service at $6.95/TB/month, designed for developers and businesses. NAS users and those needing S3 API access should use B2 Cloud Storage.

13 How does Backblaze B2 Overdrive differ from B2 Cloud Storage?

B2 Overdrive (at $15/TB/month) is designed for performance-intensive workloads requiring higher throughput. B2 Cloud Storage ($6.95/TB/month) is the standard tier for most backup and storage use cases. B2 Reserve offers custom pricing for committed capacity.
