Backblaze vs Box

What Backblaze is

Backblaze sells distinct products, most notably B2 Cloud Storage and Computer Backup. B2 is usage-billed always-hot object storage with Native and S3-compatible APIs, browser access and command-line tooling. Current public pricing starts with 10 GB free, then meters byte-hour storage, egress beyond an allowance and selected Class D transactions. Encryption, Object Lock, version history and replication are capabilities to configure—not substitutes for independent access controls and tested recovery.

What Box is

Box stores and shares files with enterprise governance: retention policies, legal holds and detailed permissions. Governance is the product: retention schedules, legal holds and granular permissions are why it appears in regulated procurement. For a small team that just needs shared folders, all of that is cost without benefit.

What Backblaze is built to do

S3-compatible API

Supports common S3 operations alongside Backblaze's Native API.

Usage-based storage

Bills stored bytes over time with separate egress and selected transaction rules.

Object immutability

Object Lock and Legal Hold can prevent deletion or change for governed retention periods.

Encryption and replication

Offers managed-key or customer-key SSE and configurable bucket replication.

What Box is built to do

Retention and legal hold

Applies policy-driven retention and preserves content for litigation.

Granular permissions

Sets access at folder and item level with external collaborator control.

Compliance certifications

Supports regulated industry requirements and audit reporting.

Choose Backblaze if

• Backup repositories whose software has verified B2 or S3-compatible support
• Media and application objects with modeled storage, download and transaction patterns
• Immutable off-site copies configured with restricted keys, Object Lock and restore drills

Skip Backblaze if

• The workload depends on an untested Amazon S3 feature or exact behavioral parity
• Required data residency, region pairing or recovery throughput is not available and verified
• No owner exists for key rotation, retention, lifecycle, replication and restore testing

Choose Box if

• Regulated organisations that need content governance, not just storage.

Backblaze: pros & cons

• Low-friction object storage: Native and S3-compatible APIs work with many existing backup and application tools.
• Published usage model: Storage, egress allowance, overage and transaction classes are documented publicly.
• Data-protection controls: Optional server-side encryption, Object Lock, version history and bucket replication support resilient designs.
• Egress options: Downloads are free up to three times average monthly storage and through named CDN/compute partners.
• Not all S3 behavior is identical: Compatibility must be checked against the exact SDK, operation and application workflow.
• Encryption is a configuration decision: Official documentation says B2 data is not encrypted by default and offers optional SSE.
• Recovery cost can vary: Large restores may exceed free egress and generate transaction, network and operational costs.
• Product confusion risk: Computer Backup retention and device rules do not describe generic B2 object storage.

Box: pros & cons

• Strong governance and compliance controls
• Granular permissions
• Good audit trails
• Costs more than consumer storage
• Interface is heavier than rivals
• Sync client has a mixed reputation
