Azure File Sync Cloud Tiering Not working

Question

Hi Everyone,

I have recently implemented Azure Cloud Sync with two things in Mind.

1. To centralise the File Share in Azure
2. To cope of the expanding Storage need of the Server. When I implemented the Azure File Sync, and enabled Cloud tiering with 25% free Volume Free Space Policy, my expectation was the storage will be freed (which current is 4%) because of the Cloud Tiering Policy. However, the space is not freed and "Cloud Tiering Space Saving " is 100% which basically means the size in cloud and in On -prem is the same.

I don't see any errors in both Azure and in Server that would indicate anything related to this.

The File Server is Windows server 2012 R2 .

Is there anything that I missed?

Hi @Netra Basyal

Welcome to Microsoft Q&A Forum. Thanks for posting you query here!

As we see that there might be configuration issues or a limitation with the version of Windows server you are using.

Please do try the below suggestions:

Since you have set a 25% free volume space policy, ensure that the local volume has enough free space available. If the current free space is only 4%, Azure File Sync may not be able to tier files as it needs to maintain the specified free space percentage.

Also, check if the cloud tiering policy is supported on Windows Server 2012 R2. Azure File Sync cloud tiering is supported on Windows Server 2012 R2, but there may be some limitations. Make sure that you are using the latest version of the Azure File Sync agent. Which you can download the latest version from the Microsoft Download Center.

However, you can monitor the cloud tiering status through the Azure portal. Check the "Space savings" metric to see if it reflects any changes. If it remains at 100%, it indicates that no files have been tiered yet.

Also, please make sure that the Azure File Sync file system filter (StorageSync.sys) is loaded correctly on your Windows Server 2012 R2. If it is not loaded, tiering will not function as intended.

If these points do not resolve the issue, consider reviewing the Azure documentation for further Troubleshoot Azure File Sync cloud tiering and also please refer the document Cloud tiering policies.
