Backblaze B2 Cloud Storage review
A low-cost object storage option with strong backup, retention, and replication features.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Backblaze B2 Cloud Storage is an always-hot object storage service for businesses, developers, IT teams, and individuals. It stores files in buckets accessible through a web interface, command-line tools, and APIs. The service is positioned for application storage, backup and disaster recovery, active archiving, media workflows, and AI data workloads. Its S3-compatible API and Native B2 API make it suitable for teams that need object storage without committing to a broader cloud platform.
Pricing is straightforward. The listed Pay as you go plan costs $6.95 per TB per month, with the first 10GB of storage always free. Free egress is available up to 3x average monthly storage, while there are no minimum file size or storage duration fees. Class A, B, and C API calls are free. This structure fits storage and backup use cases where predictable capacity costs matter, although teams with higher egress requirements should account for the stated limit. The plan also includes the service’s core storage capabilities rather than separating essential retention or replication features into additional tiers.
B2’s strongest fit is backup, archive, and application storage that benefits from ecosystem connections. Integrations include Veeam, Synology, Rclone, Fastly, Cloudflare, Snowflake, Commvault, and LucidLink. Lifecycle rules can hide and delete files, while object version retention, Object Lock retention and legal hold, server-side encryption with SSE-B2, and cross-region bucket replication support protection and operational control. Web console and command-line access add flexibility for administration. Choose B2 when low-cost storage, backup integrations, S3 compatibility, and retention controls are priorities. Consider a broader cloud platform when you need a wider range of services beyond object storage.
