Preinstallation Checklist for the Web Server

The Web Server is a web service that communicates with the CommServe to provide end users access to CommCell operations on the web.

Use this preinstallation checklist to prepare the computer where the Web Server will be installed and to gather all of the information you will need during the installation.

Verify System Requirements

Verify that the computer where you will install the Web Server satisfies the minimum requirements. For more information, see System Requirements - Web Server.

Verify License Requirements

The Web Server does not require a license.

Determine the Installation Location

Based on your environment, install the Web Server on an appropriate computer.

The Web Server requires that the Internet Information Services (IIS) is enabled on the computer where the software will be installed. If not enabled, IIS can be enabled during the installation.

Additional Packages Installed with the Web Server

Use the following table to review the packages that are automatically selected during the Web Server installation.

Gather Installation Data

Refer to the items in this section to gather the information that you will need during the installation. Record the information before you begin installing the software, so you can refer to it during the installation.

You can install the Web Server only by using the installation package that was created by the Download Manager.


If you plan to install the Web Server on a computer that has other server components installed, only the following information is required:

  • Commvault package to install

  • Destination folder for the Web Server database

Commvault package to install

Install the Web Server package, which is listed under the Server category.


If the File System Agent is not installed on the computer, the File System Core and File System packages are automatically installed with the package that you selected. The File System Agent will not consume any licenses.

To gather the required information for the File System Agent, refer to the Gather Installation Data section in the Preinstallation Checklist for the Windows File System Agent.

Client computer details

If the File System Agent, or another package, is already installed on the computer, you are not required to gather all the computer details again. The installation program reads the details from the previous installation.

Destination folder for the Database Engine

The database engine is the Microsoft SQL Server software. By default, the software binaries are installed in C:\Program Files\Microsoft SQL Server. You can change the destination folder, but it cannot be on a mapped network drive.


If you plan to perform VSS enabled backups on the Web Server computer, we recommend that you do not install SQL Server on the system drive. VSS restores might cause system state restore issues.

Destination folder for the Web Server database

By default, the database files are installed in C:\Program Files\CommVault\ContentStore. The drive must have at least 1 GB of free space. You can change the destination folder, but the folder cannot reside on the following types of drives:

  • Mapped network drive

  • FAT drive (as it does not allow temporary sparse files to be generated when creating the database snapshot, which is required for data verification)

  • Compressed drive

Configure Proxy Service (IIS)

If the Internet Information Services (IIS) is not enabled on the computer, you can enable IIS from the installation wizard. This configuration is useful if you forget to enable IIS before the Web Server installation.
