Amazon S3 vs Backblaze B2 — Object Storage Comparison with RcloneView
Both Amazon S3 and Backblaze B2 are S3-compatible object storage platforms — but they serve different use cases. Here's what to know before choosing, and how RcloneView works with both.
Amazon S3 is the foundational cloud object storage service, known for its global infrastructure, deep AWS ecosystem integration, and feature set that spans simple storage to event-driven compute triggers. Backblaze B2 is a leaner, cost-focused alternative that supports the S3 API and is particularly attractive for backup-heavy workloads. RcloneView supports both natively, so you can use each where it makes sense — or run both simultaneously.
