General availability release for Azure File Sync Agent: July 2018

Van toepassing: Azure

Introduction


This article describes the Azure File Sync general availability (GA) release for the Azure File Sync agent, including how to get it and how to run a silent installation.

The Azure File Sync agent is supported on Windows Server 2016 and Windows Server 2012 R2. It consists of three main components:

  • FileSyncSvc.exe: The background Windows service that's responsible for monitoring changes on server endpoints and initiating sync sessions to Azure.
  • StorageSync.sys: The Azure File Sync file system filter that's responsible for tiering cold files to Azure Files (when cloud tiering is enabled).
  • PowerShell management cmdlets: PowerShell cmdlets for interacting with the Microsoft.StorageSync Azure Resource Provider. By default, the cmdlets can be found at the following locations:
     
    • %ProgramFiles%\Azure\StorageSyncAgent\StorageSync.Management.PowerShell.Cmdlets.dll
    • %ProgramFiles%\Azure\StorageSyncAgent\StorageSync.Management.ServerCmdlets.dll

How to run a silent installation for new agent installation


To run a silent installation for a new agent installation, you must use the MSI package that is included in the agent installer package. To extract the MSI package, double-click the appropriate agent installer package (for example, StorageSyncAgent_V3_WS2016.exe), copy the MSI packages that are located under %systemdrive%\AfsAgentSetup to another location, and then cancel the attended agent installation.

To perform a silent installation for a new agent installation, run the following command at an elevated command prompt:

msiexec /i packagename.msi /qb /l*v AFSInstaller.log

For example, to install the Azure File Sync agent for Windows Server 2016, run the following command:

msiexec /i StorageSyncAgent.msi /qb /l*v AFSInstaller.log

Note Use the /qb switch to display restart prompts (if required), agent update, and server registration screens. To suppress the screens and automatically restart the server (if required), use the /qn switch.
