Release : 10.8.0


The scheduled backup is failing due to a name resolution error. The Control Center is possibly attempting to resolve the hostname of the system to execute the backup and may be getting a NXDOMAIN response when looking up the hostname in DNS.


This is a known issue and will be addressed with a future release.

Manual backups do not appear to be affected.


  1. Add the Control Center IP address to the local host file in Administration > Configuration > host > DNS / Time > Host name and IP Address Mapping as shown below
  2. Restart the Control Center appliance or virtual machine
