Managing Failover : What Happens When the Protected Site is Down
  
What Happens When the Protected Site is Down
If the protected site is down, you can initiate the failover from the recovery site, as described above in To initiate a failover:.
The specific VPG tab for a VPG shows whether recovery is possible.
If the Zerto Virtual Manager service is down the actual machines that are being protected can still be up, but they are only recoverable to the last checkpoint written before the Zerto Virtual Manager went down. If the vCenter Server is down, some of the protected virtual machines might not be protected.
When there is no connection with the protected site, the status for recovered VPGs is red with an Error status and green while recovery is being performed. If the protected site restarts so that Reverse Protection is possible, the status changes to orange.
