OneDrive Data Transfer Issue - Discrepancy in Storage Space Used

Copper Contributor

Hello OneDrive community,

I'm encountering an issue while transferring data between two OneDrive for Business accounts. I'd greatly appreciate any insights or assistance you can provide. The situation is described below:

  • Cloud A (current work account): Storage reducing from 1 TB to 10 GB
  • Cloud B (new account): 1 TB storage available

Therefore, I want to transfer all data from Cloud A to B. However, here are the problems that I am encountering:

  1. Cloud A storage discrepancy:
    • OneDrive browser/Windows 11 app shows 157 GB used
    • Local folder size: approximately 78 GB

This discrepancy happens even with OneDrive configured to backup all folders and "download all files" option enabled.

 

  1. Cloud B after transfer:
    • Shows only 78 GB occupied (browser/app)

Here it appears to have no discrepancy. That said,

  1. Why is there a discrepancy between the reported storage usage on Cloud A (157 GB) and the local folder size (78 GB)?
  2. How can I ensure all files from Cloud A have been successfully transferred to Cloud B?
  3. Is there a reliable method to verify the complete transfer, given the storage discrepancy? Something similar than the services that Google offers in their clouds.

I would like to add that I am using WinMerge to compare both clouds' directories. Finally, any guidance on understanding these storage discrepancies and ensuring a complete data transfer would be immensely helpful. Thank you in advance for your assistance!
