SIRIS, ALTO, and NAS: Changing from ShadowSnap to Datto Windows Agent

Follow

Topic

This article explains the process of uninstalling the ShadowSnap agent on a Windows machine and installing the Datto Windows Agent. 

Environment

  • ShadowSnap Agent
  • Datto Windows Agent

Description

Before you begin, review our Getting Started with the Datto Windows Agent article for complete information on Datto Windows Agent requirements. Note that several requirements differ from the ShadowSnap agent. 

This procedure will require you to create a new full backup chain on the Datto appliance. Ensure the Datto appliance has more free space than the amount of protected storage on the machine in question. If needed, Archive your agent first, then delete all local data.

Warnings

  • This process requires several reboots of the protected machine. 

  • Small form-factor devices (Alto, X1, X2, X4) have an agent limit that you must consider. Review the article on archived agent limits. 

  • The latest version of the Datto Windows Agent does not support Windows XP or Windows Server 2003. You must use the legacy version of DWA. for those Windows versions.

Getting started

Ensure that a backup is not in progress and pause backups on the protected machine on the remote web.

Removing the ShadowSnap agent

  • We recommend using Revo Uninstaller Pro because it ensures all files and registry entries that are associated with the installation of ShadowSnap and ShadowProtect get entirely removed.

  • An alternate but less-comprehensive method to remove ShadowSnap and ShadowProtect is using the Add/Remove Programs wizard located in the Windows control panel.

Downloading and Installing Revo Uninstaller

1. Download and install Revo Uninstaller.

2. Launch the program. Locate ShadowSnap and ShadowProtect in the Revo UI.

Removing ShadowSnap

1. Click Uninstall. Select ShadowSnap.

If you see the following error message, click OK:

"ShadowSnap is installed in the same location as StorageCraft ShadowProtect! Leftovers will be found from both applications! Carefully check the ones you want to remove!"

2. Revo Uninstaller will perform a full registry backup and create a System Restore point.

3. The StorageCraft Maintenance Wizard will launch. Select Uninstall, and then click Next.

9. Click Next. When prompted, click Yes and then Finish. If Revo finds any other leftovers after the cleanup, review the files, and remove them by clicking Select All and Delete.

10. Reboot the production machine to complete the uninstall.

Installing the Datto Windows Agent 

1. Download the version of the agent compatible with your Windows version: 

    For Windows XP & Windows Server 2003

        Download the agent software from the following link: Datto Windows Agent: Legacy Installer.

    For Windows Vista, Windows Server 2008, and Above

        Download the agent software from the Datto Downloads page.

2. Run the installer. You must have internet access both during the install and during the first start of the agent so that the software can retrieve certificates.

3. When the installer completes, you must reboot the production machine to finalize the installation of the agent.

Pairing the Datto Windows Agent

1. Archive the backup chain which used the ShadowSnap agent. This action will permanently set this dataset to read-only so that you can create a new backup chain with the Datto Windows agent.
