This article describes the improvements and issues that are fixed in the Azure File Sync Agent v14 release that is dated October 2021. Additionally, this article contains installation instructions for this release.

Improvements and issues that are fixed

Reduced transactions when cloud change enumeration job runs

Azure File Sync has a cloud change enumeration job that runs every 24 hours to detect changes made directly in the Azure file share and sync those changes to servers in your sync groups. We have made improvements to reduce the number of transactions when this job runs.

Improved server endpoint deprovisioning guidance in the portal

When removing a server endpoint via the portal, we now provide step by step guidance based on the reason behind deleting the server endpoint, so that you can avoid data loss and ensure your data is where it needs to be (server or Azure file share). This feature also includes new PowerShell cmdlets (Get-StorageSyncStatus & New-StorageSyncUploadSession) that you can use on your local server to aid you through the deprovisioning process.

Invoke-AzStorageSyncChangeDetection cmdlet improvements

Prior to the v14 release, if you made changes directly in the Azure file share, you could use the Invoke-AzStorageSyncChangeDetection cmdlet to detect the changes and sync them to the servers in your sync group. However, the cmdlet would fail to run if the path specified contained more than 10,000 items. We have improved the Invoke-AzStorageSyncChangeDetection cmdlet and the 10,000 item limit no longer applies when scanning the entire share. To learn more, see the Invoke-AzStorageSyncChangeDetection documentation.
