Backblaze B2

Yes, Backblaze B2 supports S3-compatible Object Lock, which allows you to make files immutable for a specified period. This prevents data from being deleted or modified by unauthorized users or ransomware, ensuring your backups remain safe and recoverable.

There is virtually no limit to the total amount of data you can store in B2. Individual files can be as large as 10TB when using our large file upload API, which handles multi-part uploads to ensure reliability and speed for massive datasets.

We offer several migration paths, including the Backblaze Cloud Waiter service for automated transfers and the Universal Data Migration service. For very large datasets, we can even provide physical 'Fireball' ingest devices to move your data without consuming your local bandwidth.

B2 is highly versatile and commonly used for offsite server backups, media archiving, content delivery for web applications, and long-term data preservation. Its high performance and low cost make it an excellent choice for any scenario requiring scalable, reliable cloud storage.

Absolutely. Backblaze B2 features a fully S3-compatible API, meaning you can use your existing code, scripts, and third-party applications designed for AWS S3 by simply changing the endpoint URL and credentials. This allows for a seamless 'drop-in' replacement.

Backblaze B2 integrates with a wide range of popular backup and sync tools including Veeam, MSP360, Duplicati, Synology Hyper Backup, and rclone. Our ecosystem is designed to work natively with the hardware and software you already use in your workflow.

Backblaze B2 is significantly more affordable, typically costing about 1/5th the price of Amazon S3. We offer a simple flat rate for storage with no hidden tiers, and the first 10GB of storage is completely free, making it ideal for both small projects and enterprise-scale data.

Backblaze B2 offers free egress up to three times your average monthly storage amount. For transfers beyond that, we charge a low flat rate per GB, and we also offer free egress through our partnerships with Content Delivery Networks (CDNs) like Cloudflare via the Bandwidth Alliance.

Your data is stored in secure, SOC 2 Type II compliant data centers with 24/7 monitoring, biometric access controls, and redundant power systems. We use a Reed-Solomon erasure coding strategy to shard data across multiple drives and servers, ensuring 11 nines of durability.

Yes, we strongly encourage all users to enable Two-Factor Authentication on their accounts. We support 2FA via SMS or TOTP applications like Google Authenticator and Authy, providing an extra layer of security to prevent unauthorized access to your storage buckets.
