===== Destination Pool: Recommend discontinue use of Microsoft OneDrive and Microsoft OneDrive for Business in a Destination Pool =====
Date: 2021-09-28
We do not recommend the use of Microsoft OneDrive or Microsoft OneDrive for Business with Predefined Destination Pools.
Due to newly discovered Microsoft limitations with their API, application cannot get real-time quota usage of either OneDrive destinations when used in a Destination Pool. When a pool containing OneDrive destinations exceeds quota, we do not get accurate quota exceed response as Microsoft allows data to continue to be written to storage for a short time, in turn if you exceed your storage limit, your OneDrive account will be frozen by Microsoft. Simply adding more OneDrive destinations into a Destination Pool will not 'unfreeze' your OneDrive storage.
This Microsoft overrun affects all CloudBacko products versions.
What if your Destination Pool are currently using OneDrive or OneDrive for Business ?
You can continue to use it, however you run the risk that Microsoft could freeze or delete your data stored in that destination. You are advised to create new Predefined Destination Pools using alternative destinations hosts, then retire the use of the former OneDrive Destination Pool.
Are you affected if your Destination Pool is a mix of OneDrive and another type of storage?
Yes
How do you know if your OneDrive / OneDrive for Business destination is frozen?
When you login to your Microsoft OneDrive / OneDrive for Business, an alert may appear that your storage account is frozen due to exceeding storage quota.
