About:
The B2 Command Line Tool provides a powerful and intuitive interface for managing data in Backblaze B2 Cloud Storage. It enables users to efficiently upload, download, and manage files and buckets directly from the terminal. The tool is designed for developers and system administrators to automate backups, data transfers, and cloud infrastructure management.
Key Features:
  • Direct file operations (upload, download, copy, delete) on B2 buckets
  • Support for large file uploads with automatic chunking and parallel processing
  • Integration with standard Unix pipes and streams for scripting
  • Bandwidth and thread count configuration for performance tuning
  • Lifecycle rules and versioning management for bucket configuration
Use Cases:
  • Automating cloud backups of local directories or server data
  • Integrating B2 storage into CI/CD pipelines for artifact management
  • Migrating data between cloud providers or local storage and B2
  • Analyzing storage usage and costs through detailed file listings
Alternatives:
  • rclone – rclone supports multiple cloud providers including B2, while b2-tools is specialized for Backblaze with deeper native integration.
  • aws-cli – aws-cli is for AWS S3; b2-tools uses Backblaze's native API which can be more cost-effective for B2 users.
