How to Manually Synchronize and Verify Files, the Registry, and Related Tasks with Neverfail Continuity Engine


This article provides information about how to manually synchronize and verify files, the registry, and related tasks with Neverfail Continuity Engine. 

More Information

The Summary Status pane of the Status page of the Engine Management Service User Interface displays the synchronization status of data on the Secondary (passive) server and Tertiary (passive) server if installed.

The synchronization status may read three different values depending on the state the system has reached with its verification and synchronization:

Synchronized - the files have been verified as synchronized

Out-of-Synch / Unsynchronized - the file is not synchronized on the active and passive servers. This is common following a failover and manual synchronization and verification must be carried out

Question Mark graphic - the file or folder has not been checked because either a full system check has not been performed or the file or folder has not yet been reached by the full system check. 


How to Manually Synchronize Files and the Registry

If using the EMS UI:
When a file or folder has been detected as unsynchronized, the Summary Status pane of the Status page displays the Data on Secondary or Data on Tertiary as Unsynchronized. Engine Management Service UI signals this both via yellow coloring of the cluster nodes representations and marking the Synchronization status as Unsynchronized. 

The Unsynchronized files can be manually synchronized by navigating to the Actions drop-down menu and selecting the Check filesystem option.

Additional options if using the Advanced Management Client

Where folders are selected, the Include Subdirectories check box can be selected to ensure all files within the selected folder have been synchronized.

The process to verify and synchronize is identical to the synchronize process except that you select the Verify and Synchronize button. Select the Include Sub-directories check box to ensure all underlying files and subfolders are included in the verification and synchronization operation.

When a verification or synchronization operation is underway, the progress bar graphic will display the status.

Each manual or automatically scheduled synchronization and verification request is defined as a Task. Other tasks are queued for processing until the current task is completed. Each task is listed in the task list to the right of the current task frame.

How to Cancel a Synchronization or Verification Task 

Individual tasks can be cancelled if required. However, canceling tasks that have been automatically triggered may lead to the system becoming unchecked and a warning will display.

If the system is unchecked, recover by performing a Full System Check, which is triggered by selecting the Full System Check button. A Full System Check performs the same block level check of all the files, set by the file filters that the initial startup synchronization and verification performs.

How to Review the Status of Registry Replication

The status of registry replication is displayed in the Advanced Management Client> Registry Synchronization Status pane of the Data: Replication page and displays the same seven icons that the System page displays.

If using the EMS UI:

Registries can be manually synchronized by navigating to the Actions drop-down menu and selecting the Check filesystem option.

If using Advanced Management Client:
The Full Registry Check button allows all the registry keys matching the built-in registry filters to be re-scanned and synchronized between the servers.
