Backblaze
Always-hot, S3-compatible cloud storage and unlimited computer backup at a fraction of hyperscaler prices
About Backblaze
Backblaze is a publicly traded (NASDAQ: BLZE) cloud storage company with two product lines: B2 Cloud Storage, an S3-compatible object storage service priced from $6.95 per TB per month with free egress up to 3x stored data, and Computer Backup, an automatic, unlimited backup service for Mac and Windows computers. It targets developers, IT teams, MSPs, media workflows, and individuals who want predictable storage costs without AWS-style egress and API fees.
Pros & Cons
Pros
- B2 storage costs a fraction of AWS S3, Google Cloud Storage, and Azure Blob for most workloads
- Free egress up to 3x stored data and free API calls remove the surprise fees common with hyperscalers
- S3-compatible API lets most backup tools and apps switch over without code changes
- Computer Backup is genuinely set-and-forget with unlimited data for a flat per-computer price
- Free mailed hard drive restores make large recoveries practical on slow connections
- Publicly traded company with a long track record and published drive reliability statistics
Cons
- Initial Computer Backup uploads can take days or weeks for large data sets
- Access controls are simpler than AWS IAM, which limits fine-grained permission setups
- No compute, database, or broader cloud services; you pair B2 with other providers
- Computer Backup does not cover NAS or server backups, which require B2 plus third-party software
- Private encryption keys cannot be recovered by Backblaze if you lose them
