Neverfail IT Continuity Engine v7.1.2 - Release Notes


This Knowledgebase article provides information about this specific release of Neverfail IT Continuity Engine v7.1.2


This release of Neverfail IT Continuity Engine is a patch release that applies to Neverfail IT Continuity Engine v7.1.x and addresses the loss of Neverfail Engine registry configuration information caused by upgrading to JAVA 8 Update 60. 

IT Continuity Engine v7.1.2 is the latest addition to the Neverfail family of continuous availability technologies that has been optimized for use in VMware virtualized environments. It provides product capabilities and benefits similar to Neverfail Heartbeat, but with a highly simplified and automated deployment process. IT Continuity Engine's deep integration with VMware vSphere provides complementary add-on HA/DR value in addition to the native VMware BCDR oriented solutions such as HA, SRM, and so on.

What’s New

Engine 7.1.2 builds on the core features and benefits of Engine 7.0 by adding the following:

  •  Tertiary Support
    • Create new trio (tertiary) deployments via an easy to use wizard
    • Transition an existing pair (HA/DR) to a trio (tertiary) deployment
  • Streamlined Deployment Options
    • The ability to customize IP configurations on each node during each deployment by allowing you to select which IP will be your public and which interface you want to use for the Neverfail Channel
    • Support for multiple NICs. Use a single or dual NIC configuration while using the Engine deployment wizard.
  • Redesigned Network Management
    • A complete redesign of packet filtering to leverage Windows Filtering Platform thus restricting network access on passive nodes without the need for hardware specific network interface device drivers.
    • Enhancements to the Configure Server wizard that allow DHCP to be selected for public and/or channel IP addresses.
  • Redesigned User Interface (Web Services)
    • Engine Management Service now has its own web portal service which enables management and deployment without the need for VMWare specific plug-ins.
    • Simplified upgrade of managed servers.
    • The ability to upgrade a a single server from a cluster by IP address.
  • Licensing Enhancements
    • Offline key application process. This now allows for pre-authorized license keys to be deployed quickly and easily for systems that are not connected to the internet.
  • Bundled Plug-ins
    • Neverfail IT Continuity Engine now includes common plug-ins bundled into the setup .msi file and installed automatically.
  • Enhanced Fast Check support for:
    • File servers with 1 Million + files
    • Closed files for running applications
    • Fast Check use at first time start-up
    • Improved administrator control over options for synchronization time versus application start-up time.
    • Configurable FileInfoCache
  • Citrix Xen to VMWare as a Deployment Option
  • Neverfail Engine System Integrity
    • Enhanced resistance to Neverfail IT Continuity Engine registy preference configuration loss.

Known Issues

Install/Uninstall/Upgrade of Neverfail IT Continuity Engine Management Server

  • After successfully deploying the Primary server and attempting to deploy the Secondary virtual machine, the deployment fails with the message: Creating VM. 100% Timed-out waiting for SECONDARY VM to complete auto-configuration.
    Workaround: Reboot the Secondary server and then wait for the reconfiguration to complete (EN-1573).
  • Performing a single node upgrade and then cancelling the upgrade will continue to display the single node upgrade status in the server list.
    Workaround: Navigate to Manage -> Remove Server to remove the single node upgrade status from the server list. Removing the upgrade status may result in the main entry for the cluster being removed as well. To re-add the cluster, navigate to Manage -> Add (EN-1491).
  • When performing an upgrade and selecting the Upgrade only a specific server in the cluster option, the progress status for the Secondary/Tertiary sever being upgraded is displayed in the Primary server Status field.
    Workaround: This can be safely ignored as it is only a cosmetic status message (EN-1491).
  • After deploying the Engine, the navigation through Status/Events/Tasks/Rules/Settings is blocked.
    Workaround: Refresh the page and login again (EN-965).
  • When upgrading Neverfail IT Continuity Engine with the Neverfail System Tray tool running, the About information may not be updated.
    Workaround: Restart the Neverfail System Tray tool (EN-867).
  • The Engine Management Service User Interface fails to display a correct status when it is closed and reopened during an upgrade process (EN-1083). 
  • On uninstallation of Neverfail IT Continuity Engine Management Service, you may receive a popup about another process holding a lock on a log-file. 
    Workaround: Start Task Manager and terminate any instances of nfremoteexec.exe (Ref-15310)
  • After uninstalling Neverfail Engine, when reinstalling, the status of the operation may briefly display inaccurately. (Ref-16640)
  • Attempting to upgrade multiple pairs of Neverfail IT Continuity Engine v7.0 to v7.1.1 results in the sequential upgrade of the pairs rather than a simultaneously upgrade and requires the user to click Next to continue the upgrade on the additional pair (EN-919).  


  • In the event the registry preferences be lost, they will be restored during the Neverfail Engine Server service restart (EN-1447).
  • Logging out of the Neverfail Engine Management Service User Interface with a server pair selected in the Protected Servers pane and logging back in may result in the server cluster's information failing to display.
  • Workaround: Refresh the Neverfail Management Engine User Interface page (F5) and re-login (EN-1018).
  • The Plan Execution pane steps displayed may not correspond to the server cluster selected in the Protected Servers pane except when an update arrives (EN-905).
  • When a trio is installed and the Secondary server becomes dead or deleted, you reinstall the entire trio (EN-508).
  • Synchronization status between servers in a trio is relative, for example, "A" is in-sync with "C" if "A" is in-sync with "B" and "B" is in-sync with "C" (EN-1037).
  • When extending a pair to a trio, the status message displayed during tertiary deployment may not be accurate (EN-1094).  
  • If a protected server is removed and re-added via Discover Protected Servers in the Neverfail Engine Management Service, old tasks may display in the tasks pane for the newly added protected server (Ref-15470)
  • Multiple concurrent tasks of the same type may not be shown correctly in the Neverfail Engine Management Service (Ref-16522)
  • When attempting to collect logs via the Neverfail SCOPE Configuration Tool, the dialog prompting you to put Neverfail into the Maintenance Mode is hidden behind the Neverfail SCOPE Configuration Tool dialog and prevents you from collecting the logs (Ref-14294).
    Workaround: Either maximize the dialog icon from the Windows Toolbar or use Alt+Tab to bring the dialog forward so that a response can be given to the prompt.
  • After performing a switchover with VMware Platform Services Controller installed, the user must restart their browser and re-login to the vSphere Web Client v6.0 (EN-1310).
  • The switchover plan may fail after unprotecting and then again protecting an application (EN-1446).


  • Setup —Neverfail for vSphere 6.0 Plug-ins do not support the ` (grave accent) character
