FAQ

My organization has a large amount of files that we need to access quickly and easily. How does Backblaze meet this need?

Backblaze offers specialized cloud storage that makes it astonishingly easy for businesses to store, use, and protect their data. The B2 Cloud Storage platform offers always-hot, S3 compatible object storage that’s readily available through APIs, ISVs, CLI, and web UI. With a tech stack agnostic approach that integrates with companies' existing workflows and preferred compute and CDN tools, the platform fits multi-cloud, hybrid cloud, and other IaaS strategies.

Does Backblaze B2 support hybrid cloud/multi-cloud infrastructure?

Yes, Backblaze B2 is often used within organizations’ hybrid cloud or multi-cloud infrastructure. You can easily integrate Backblaze B2 via API, CLI, or third-party software and/or hardware integration.

Is it possible to migrate my data from a legacy storage solution to Backblaze B2?

Yes, Backblaze offers Universal Data Migration to support moving or copying data from a range of sources, including legacy public cloud providers such as AWS, Google, and Microsoft, cloud drive services such as Google Drive and Box, on-premises servers, storage area network (SAN), and network attached storage (NAS), and LTO tape media. Backblaze will help cover migration costs with qualifying commitments.

Why should I trust Backblaze with my data?

Backblaze has proven itself as a provider of tried and trusted cloud storage solutions since 2007. It has exabytes of customer data under management for respected organizations around the world. The company is also known for transparent business practices—ranging from a consistent pattern of sharing data that can improve our industry to our choice to operate as a publicly traded company (Nasdaq: BLZE). We have nothing to hide in our easy to adopt and easy to manage solutions, and in our affordable and straightforward pricing structures.

How does Backblaze support sustainability?

Storing and using data is energy intensive–there’s just no way around this fact. However, by centralizing and optimizing data storage within our network of data centers, the Backblaze Storage Cloud operates more efficiently than distributed, on-premises systems storing the same volume of data. That said, the company understands that there is still more work to be done and is committed to a more sustainable future. Backblaze is acting accordingly to do its part and help B2 Cloud Storage customers reduce their carbon footprints and progress on their environmental, social, and governance (ESG) policies. Backblaze from its beginnings focused on building a sustainable business. We lead the industry with our learning—for more than 10 years, sharing data and insights from more than 200,000 spinning drives to help others globally to do better. Additionally, we’ve operationalized impact reduction, from supporting data lifecycle rules to help customers store selectively and thereby manage down energy consumption, to recycling decommissioned hardware including drives, to moving into our Stockton1 data center for river cooling, no water consumption, no water pollution, no chemical use, and projected carbon footprint approximately 30% below average.

Is Backblaze B2 compatible with third-party applications and integrations?

Yes, Backblaze B2 integrates seamlessly with thousands of hardware and software tools, likely including those you use in your workflow. Some examples of our Alliance Partners are Veeam, MSP360, Arq, rclone, Commvault, Veritas, iconik, LucidLink, Synology, Fastly, and Vultr. You can find a more extensive list of tested integrations here; and many more will work seamlessly with Backblaze B2 given its S3 compatibility.

How can I get unlimited free egress?

Backblaze B2 offers unlimited free egress when downloading to or through partner content delivery networks (CDNs) and compute services, including Fastly, Cloudflare, bunny.net, CacheFly, CoreWeave, Equinix Metal, Vultr, and phoenixNAP. Additionally, B2 Overdrive includes unlimited free egress to any destinations, supporting throughput-intensive workloads.

What is B2 Overdrive?

Backblaze B2 Overdrive is a high-throughput cloud object storage solution, engineered for workloads needing rapid data access. Built on top of Backblaze B2, it provides increased storage and networking throughput, and includes unlimited free egress to facilitate intensive data operations without prohibitive costs.

Who is B2 Overdrive best suited for?

B2 Overdrive is specifically designed for organizations with demanding, throughput-intensive applications like AI/ML training and inference, high-performance compute (HPC), large-scale data analytics, media processing pipelines, and research compute.

How does Backblaze's 3x free egress work?

All Backblaze B2 Cloud Storage users enjoy free data egress (also known as download) up to 3x their average monthly storage amount. The monthly average is determined based on byte hours over the billing cycle, with total egress up to 3x the average provided free.; Egress exceeding this amount is priced at $0.01/GB.
