This article provides information about how to manually synchronize and verify files, the registry, and related tasks with Neverfail Engine.
About the Replication tab of the Data page:
From the Neverfail Advanced Client, navigate to the Data: Replication page.
On this page, the global status of file synchronization and verification is displayed graphically in the File Synchronization Status pane.
The Data: Replication page presents a tree like structure on the left side showing the protected folders as defined by the file filters.
Each level of the tree can be expanded or collapsed by double-clicking the appropriate folder. If you select the pointer icon that appears to the left side of a folder, it will display the subfolders within that folder. Protected files and their synchronization status, within folders, are displayed on the right side of the pane.
The synchronization status for each file may read three different values depending on the state the system has reached with its verification and synchronization:
In-Synch - the files have been verified as synchronized
Out-of-Synch - 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 and Verify Files and the Registry
When a file or folder has been detected as Out-of-Synch , the folder structure to the left side of the Neverfail Advanced Client changes replacing standard folder icons with red folder icons from the Out-of-Synch file up the tree to the parent drive.
The Out-of-Synch files can be manually synchronized by clicking the Synchronize button, which rather than re-synchronizing the entire protected file structure, will just resynchronize the files listed in the right pane. Any files may be resynchronized at any time by selecting their entry in the file list and clicking the Synchronize button in the controls frame.
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 Registry Synchronization Status pane of the Data: Replication page and displays the same seven icons that the System page displays.
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.
