What Is Backblaze B2 Cloud Storage? Features, Pricing, and Complete Beginner Guide (2026)
In the rapidly evolving digital landscape of 2026, data has become the most valuable asset for both individuals and enterprises. Whether you are a developer looking for a place to host application assets, a small business owner securing your archives, or a creative professional protecting 8K video files, cloud storage is no longer optional—it is essential. Among the top-tier providers, Backblaze B2 Cloud Storage stands out as a leader in affordability, simplicity, and performance.
If you have been searching for "Backblaze S2," it is important to clarify that while Backblaze is often compared to Amazon S3 (Simple Storage Service), its flagship object storage product is officially named Backblaze B2. In this guide, we will explore why B2 has become the go-to alternative to "hyperscaler" services, its latest 2026 features, and how you can get started today.

Understanding Backblaze B2: The "S3-Compatible" Powerhouse
Backblaze B2 is an Infrastructure-as-a-Service (IaaS) offering that provides "hot" cloud object storage. Unlike "cold" storage (which may take hours to retrieve), "hot" storage means your data is available instantly, making it perfect for active backups, content delivery, and live application data.
The term "S3-compatible" is crucial here. It means that Backblaze B2 uses the same API language as Amazon S3. For you, this means that almost any software designed to work with Amazon can switch to Backblaze with a simple change of the "endpoint" URL. This interoperability has made B2 a favorite for those wanting to escape the high costs of the Amazon ecosystem without rewriting their entire workflow.
Key Features of Backblaze B2 in 2026
Backblaze has consistently updated its platform to meet modern security and speed requirements. Here are the core features that define the service in 2026:
1. Ransomware Protection with Object Lock
In an era where cyberattacks are increasingly sophisticated, Object Lock is a standout feature. It allows you to make files "immutable" for a set period. Once locked, no one—not even an administrator with full credentials—can delete or modify those files. This provides a "virtual air gap" that ensures your backups remain untouched during a ransomware outbreak.
2. Cloud Replication
For organizations requiring high availability or data sovereignty, B2 offers automated Cloud Replication. You can automatically sync data between different Backblaze data centers (for example, from the US to the EU). This ensures that if one region faces a catastrophic event, your data remains accessible from another geographic location.
3. Universal Data Migration
Moving terabytes of data from one provider to another used to be a logistical nightmare. In 2026, Backblaze’s Universal Data Migration service simplifies this by handling the transfer for you. If you are moving a significant amount of data from Amazon S3, Google Cloud, or even on-premises tape systems, Backblaze often covers the transfer costs to help you switch.
4. B2 Overdrive (High Throughput)
For AI training models and high-end media production, Backblaze now offers B2 Overdrive. This tier provides dedicated networking and storage resources for maximum performance, supporting speeds up to 1Tbps. It is specifically designed for workloads where "GPU wait time" is a bottleneck.
Backblaze B2 Pricing (2026 Update)
One of the primary reasons users migrate to Backblaze is the transparent, "no-nonsense" pricing model. Unlike other providers that charge for "PUT," "GET," and "LIST" requests in a confusing web of micro-transactions, Backblaze keeps it simple.
- Storage Cost: Approximately $6 per Terabyte (TB) per month.
- Egress (Downloads): Backblaze offers free egress up to 3x your average monthly storage. For example, if you store 10TB, you can download 30TB for free. Beyond that, egress is a flat $0.01 per GB.
- API Transactions: Class A calls (uploads) are free. Small daily allowances cover most Class B and C calls for average users.
- Free Tier: Every account starts with 10GB of free storage, which never expires.
Pricing Comparison Table
| Provider | Storage (per TB/mo) | Egress (per GB) | Complexity |
|---|---|---|---|
| Backblaze B2 | $6.00 | Free (up to 3x) / $0.01 | Low |
| Amazon S3 (Standard) | ~$23.00 | ~$0.09 | High |
| Wasabi | ~$6.99 | $0.00* (Minimums apply) | Medium |
*Note: While Wasabi offers free egress, they enforce a minimum storage duration of 90 days, which can be costly for fluctuating data.
Backblaze B2 vs. Personal Backup: What’s the Difference?
It is a common point of confusion for beginners: Should I use Backblaze Computer Backup or Backblaze B2? Here is the breakdown:
- Backblaze Personal/Business Backup: This is a "set it and forget it" software for your Mac or PC. It backs up everything on your computer for a flat annual fee. You cannot choose specific files easily, and it is not meant for servers or NAS devices.
- Backblaze B2: This is raw cloud storage. You pay only for what you use. It requires a third-party "connector" or integration (like Cyberduck, Duplicati, or Synology Cloud Sync) to work. It is the correct choice for servers, websites, and long-term archiving.
Complete Beginner Guide: How to Set Up Backblaze B2
Setting up B2 is straightforward, even if you are not a developer. Follow these steps to get your first bucket live:
Step 1: Create an Account
Navigate to the Backblaze website and sign up for a B2 Cloud Storage account. You don’t need a credit card to start using the 10GB free tier.
Step 2: Create a "Bucket"
A "bucket" is simply a container for your files.
- Log in to your dashboard.
- Click "Buckets" and then "Create a Bucket."
- Give it a unique name (e.g., my-secure-archive-2026).
- Choose your privacy setting (Private or Public).
- Pro Tip: Enable Object Lock during this step if you want ransomware protection.
Step 3: Generate Application Keys
To connect third-party apps to your storage, you need credentials. Go to "App Keys" and click "Add a New Application Key." Make sure to copy the keyID and applicationKey immediately, as they won't be shown again.
Step 4: Choose an Integration
Since B2 doesn't have a dedicated "folder" on your desktop by default, most users use an integration:
- For Desktop Users: Use Cyberduck or Mountain Duck to drag and drop files like a regular USB drive.
- For NAS Users: Use Synology Cloud Sync or QNAP Hybrid Backup Sync.
- For Developers: Use the B2 CLI (Command Line Interface) or the S3-compatible API.
Is Backblaze B2 Right for You?
As we look at the storage market in 2026, Backblaze B2 remains the "sweet spot" for several types of users:
- The Archivist: If you have 50TB of family photos or business records that you need to keep safe but don't access daily, B2 is significantly cheaper than physical hardware maintenance.
- The SaaS Developer: With S3 compatibility and predictable billing, B2 is ideal for hosting user-generated content or logs.
- The IT Manager: Using B2 as a destination for Veeam or MSP360 allows for enterprise-grade disaster recovery at 1/5th the cost of legacy providers.
Conclusion
Backblaze B2 (often mistakenly called S2) has cemented its place in 2026 as the most reliable and cost-effective object storage solution available. By stripping away the complexity of traditional cloud giants and focusing on "always-hot" performance at a flat $6/TB rate, it empowers everyone from solo creators to exabyte-scale enterprises to own their data without fear of "surprise" bills.
