Windows File System iDataAgent

OnePass for Windows

Additional Considerations


When you install the CommServe on a Windows Server 2012 computer, consider the following:

Using Third-Party Tools That Behave Like the Windows Start Menu

Windows Server 2012 and Windows 8 computers lack the Start menu feature from previous Windows versions. However, there are third-party tools (like Start8), which behave like the Start menu. For the CommServe to run smoothly on a Windows Server 2012 computer, disable these programs as they cause problems with the TCP/IP network.

Windows File System iDataAgent

Change Journal scan method is not supported on Resilient File System (ReFS) volumes on Windows Server 2012, 2012 R2, and Windows 8.x computers. The Recursive Scan or Optimized Scan method is used to backup data.

Restore from Deduplicated Volumes

Windows Server 2012 and Windows Server 2016 has a deduplication feature that can be enabled. Data from deduplicated volumes will be backed up in its original state (uncompressed). Therefore, during a restore, ensure that you have enough storage space on the volume to restore the full data size.

OnePass for Windows

You cannot view the offline stub icon for offline stubs on the local disks using the Windows Explorer.

Additional Considerations

The following sections list other important considerations when using Windows Server 2012, 2012R2, and Windows 8.x.

AlwaysOn Provided by SQL 2012 or Later

AlwaysOn is a new implementation on clusters. You can protect the AlwaysOn configuration on your CommServe and client computers.


Install .NET Framework 3.5 prior to installing Commvault. You can do so either by placing the Windows Server 2012 DVD in the disk drive or mounting the ISO, or by using one of the following procedures:

  1. Installing .Net Framework using Server Manager
  2. Installing .Net Framework using PowerShell
  3. Installing .Net Framework from Command Line

Installing .Net Framework Using Server Manager

  1. Open Server Manager, click the Manage tab, and then click Add Roles and Features.
  2. Click single server or remote install, then click Next.
  3. On the Before you Begin window, click Next.
  4. On the Select installation type window, click Next. Make sure that Role-based or feature-based installation optionis selected.
  5. Select the local computer and then click Next.
  6. Click Next.
  7. On the Select features window, expand .Net Framework 3.5 Features and then select .Net Framework 3.5 (includes .Net 2.0 and 3.0).
  8. Click Install to complete the installation of .Net Framework 3.5.

Installing .Net Framework Using PowerShell

Open Windows PowerShell and run the following command to install the .Net Framework:

Add-windowsfeature NET-Framework-Core

Installing .Net Framework from Command Line

Run the following command to install .Net Framework from command line:

DISM.exe /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:x:\sources\sxs

Where x is the DVD drive (or mounted ISO), and the LimitAccess flag ensures Windows does not download files from the Internet.

Installing Windows File System iDataAgent from the CommCell Console

Remote installs from the CommCell Console on Windows 8 client fail when the client computer is not a part of a domain. To resolve this issue, enable User Account Control: Admin Approval Mode for the Built-in Administrator account on theclient's Local Security Policy dialog box.

Virtual Server iDataAgent (Hyper-V)

The Microsoft Hyper-V iDataAgent will back up all the data on a Windows Server 2012 or 2012 R2 computer.
