Migrate Between Wasabi, Backblaze B2, and AWS S3 — S3-Compatible Cloud Migration with RcloneView
Found a better deal on S3-compatible storage? Wasabi, Backblaze B2, and AWS S3 all speak the same protocol — migrating between them should be easy. With RcloneView, it is.
S3-compatible storage has become the standard for object storage. When you find a provider with better pricing, more features, or different regional coverage, you shouldn't be locked in. Since Wasabi, Backblaze B2, and AWS S3 all use the S3 API, RcloneView can move data between them seamlessly.

Price Comparison
| Feature | AWS S3 Standard | Backblaze B2 | Wasabi |
|---|---|---|---|
| Storage (TB/month) | $23 | $6 | $7 |
| Egress (TB) | $90 | $10 | Free* |
| Minimum storage duration | None | 1 day | 90 days |
| Free tier | 5 GB (12 months) | 10 GB | None |
| API compatibility | Native S3 | S3-compatible | S3-compatible |
*Wasabi's "free egress" has a fair use policy — egress should not exceed storage volume.
Migration Scenarios
Wasabi → Backblaze B2
Wasabi's 90-day minimum storage policy charges you even if you delete files early. If your usage pattern involves frequent file turnover, B2 (with no minimum) may be cheaper.
Backblaze B2 → Wasabi
Wasabi offers predictable pricing with no egress fees. If you download data frequently, Wasabi's flat-rate pricing saves money.
AWS S3 → Backblaze B2 or Wasabi
AWS S3 is the most expensive option. Moving archival or backup data to B2 or Wasabi can cut costs by 70–80%.
Any → AWS S3
If you need AWS ecosystem integration (Lambda, CloudFront, Athena), S3 is the only choice.
How to Migrate
1) Add both providers
2) Browse and compare
3) Run the migration
Use a Copy job for safe migration:
4) Verify
5) Monitor large transfers
Minimize Migration Costs
Egress is the biggest cost
When migrating FROM AWS S3, egress charges add up. For 10 TB: $900 in S3 egress. Plan accordingly:
- Migrate in phases — Spread across billing cycles.
- Prioritize cold data — Migrate infrequently accessed data first.
- Use bandwidth limits to control daily egress volume.
Backblaze B2 egress
B2 offers free egress through Cloudflare (Bandwidth Alliance). If your destination supports it, use the Cloudflare integration.
Wasabi considerations
Wasabi charges for 90 days minimum. Don't delete data from Wasabi within 90 days of upload, or you'll pay the full 90-day charge anyway.
Post-Migration Steps
- Verify all objects — Folder Comparison confirms completeness.
- Update application configs — Point your apps to the new endpoint.
- Test access — Ensure applications can read/write to the new provider.
- Keep source active — Maintain the old provider for 30 days as fallback.
- Delete source data — After confirming everything works.
Getting Started
- Download RcloneView from rcloneview.com.
- Add source and destination S3-compatible remotes.
- Run a Copy job to migrate data.
- Verify with Folder Comparison.
- Update applications and decommission the old provider.
Same API, different provider, better price.
