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

Storage1 TB/month5 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

Connect OneDrive in RcloneView
  1. Open RcloneView and click New Remote.
  2. Select Microsoft OneDrive.
  3. Click Authorize — a browser window opens for Microsoft OAuth.
  4. Log in and grant access.
  5. Choose your OneDrive type (Personal, Business, or SharePoint) and save the remote as onedrive.

Step 2 — Connect Backblaze B2 in RcloneView

  1. Log in to the Backblaze dashboard and navigate to App Keys.
  2. Create a new application key with Read and Write access to your target bucket.
  3. Note the keyID and applicationKey.
  4. In RcloneView, add a new remote of type Backblaze B2.
  5. 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:

SettingValue
Sourceonedrive:/Archives/ (or whichever folder you're migrating)
Destinationb2:onedrive-archive-2026/
ModeCopy (preserves OneDrive copy until verified)
Transfers4–8 concurrent (adjust to your bandwidth)
ChecksumEnabled
Transfer OneDrive to Backblaze B2 in progress

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:

Verify OneDrive to B2 migration

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:

  1. Switch the job mode to Sync instead of Copy.
  2. Open Schedule and set a recurring interval (e.g., nightly at 2 AM).
  3. 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

  1. Download RcloneView from rcloneview.com.
  2. Add OneDrive and Backblaze B2 remotes through RcloneView's setup wizard.
  3. Create your B2 bucket in the Backblaze dashboard.
  4. 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.
