New Features

  • Neverfail Heartbeat v6.5.1 is Certified on Windows Server 2008 R2.
  • Orphaned files management - Neverfail Heartbeat now allows the user to identify and/or delete orphaned protected files on the passive server that do not exist on the active server.
  • Controlled Shutdown - Neverfail Heartbeat can now be configured to force Windows Server to wait for replication to complete before shutting down thereby ensuring Neverfail Heartbeat servers shutdown in a synchronized state.
  • Fast Check - Neverfail Heartbeat can now be configured to perform a Fast Check of the protected set. This optimization process uses time stamp and attribute information to accelerate the file verification process. When combined with Controlled Shutdown, Neverfail Heartbeat performs an unattended restart of the system.
