Migrate OneDrive to Backblaze B2 for Affordable Cloud Backup with RcloneView
OneDrive storage costs add up — especially for archive-heavy teams or individuals with terabytes of data. Backblaze B2 offers S3-compatible object storage at a fraction of the price. RcloneView makes the migration straightforward.
OneDrive is convenient for active collaboration, but it's not the most cost-effective choice for long-term archives, cold backups, or large media collections. At roughly $0.006/GB per month, Backblaze B2 is significantly cheaper than OneDrive's per-user plans for data you access rarely. Moving archival data from OneDrive to Backblaze B2 — while keeping active working files in OneDrive — is a smart cost optimization strategy that RcloneView can execute without any command-line expertise.

When Does This Migration Make Sense?
- You're over your Microsoft 365 storage quota and want to avoid upgrading.
- You have large media archives (photos, videos, project files) sitting in OneDrive that you rarely access.
- You're replacing OneDrive with Backblaze B2 as your primary backup destination.
- You want S3-compatible storage with native rclone support and no egress fees to other regions.
Cost Comparison: OneDrive vs Backblaze B2
| Storage | 1 TB/month | 5 TB/month |
|---|---|---|
| OneDrive (Microsoft 365) | ~$9.99/user | ~$50+ (per user limits) |
| Backblaze B2 | ~$6.00 | ~$30.00 |
For archive-heavy users, Backblaze B2 can cut your storage bill by 40–60%.
Step 1 — Connect OneDrive in RcloneView
- Open RcloneView and click New Remote.
- Select Microsoft OneDrive.
- Click Authorize — a browser window opens for Microsoft OAuth.
- Log in and grant access.
- Choose your OneDrive type (Personal, Business, or SharePoint) and save the remote as
onedrive.
Step 2 — Connect Backblaze B2 in RcloneView
- Log in to the Backblaze dashboard and navigate to App Keys.
- Create a new application key with Read and Write access to your target bucket.
- Note the keyID and applicationKey.
- In RcloneView, add a new remote of type Backblaze B2.
- Enter the keyID and applicationKey, name it
b2, and save.
Step 3 — Create the Target Bucket
In Backblaze B2, create the destination bucket before migrating:
- Bucket name: choose a unique name (e.g.,
onedrive-archive-2026) - Bucket type: Private (for personal backups) or Public (for media delivery)
- Versioning: Optional — enables recovery of overwritten files
Step 4 — Run the Migration
Open Jobs in RcloneView and configure:
| Setting | Value |
|---|---|
| Source | onedrive:/Archives/ (or whichever folder you're migrating) |
| Destination | b2:onedrive-archive-2026/ |
| Mode | Copy (preserves OneDrive copy until verified) |
| Transfers | 4–8 concurrent (adjust to your bandwidth) |
| Checksum | Enabled |
Click Run. RcloneView shows file-by-file progress, transfer speed, and estimated completion time.
Step 5 — Verify the Migration with Folder Comparison
When the job finishes, use RcloneView's Folder Comparison to verify that every OneDrive file landed in B2:
Any discrepancies appear highlighted. Re-run the job — rclone skips files that are already present and retransfers only the missing ones.
Step 6 — Schedule Ongoing Backups (Optional)
If you want to keep B2 as a live backup of OneDrive going forward:
- Switch the job mode to Sync instead of Copy.
- Open Schedule and set a recurring interval (e.g., nightly at 2 AM).
- New or changed OneDrive files will be backed up to B2 automatically.
Tips for Large OneDrive Migrations
- Migrate folder by folder — break large accounts into 100–500 GB chunks.
- Avoid peak hours — Microsoft throttles OneDrive API access under heavy load.
- Use bandwidth limits — set a limit in RcloneView to avoid impacting daily work during business hours.
- Keep OneDrive active — don't delete files from OneDrive until B2 is verified.
Getting Started
- Download RcloneView from rcloneview.com.
- Add OneDrive and Backblaze B2 remotes through RcloneView's setup wizard.
- Create your B2 bucket in the Backblaze dashboard.
- Copy, verify, then decide whether to keep OneDrive as active storage or fully switch to B2.
Less Microsoft lock-in, lower costs, and S3 compatibility — Backblaze B2 is a smart landing zone for OneDrive archives.
