Before disaster, you can configure viocli backup scheduler and duplicate the backup file to another vCenter.

Create VMware Integrated OpenStack Scheduled Backup Task

You can automatically backup your VMware Integrated OpenStack deployment on a regular schedule. For more information about creating a scheduled backup task, see Scheduled Backup.

Save Backup Data Outside the Source Site

You must save the backup data outside the source site. For example, you can download the backup data from the content library and upload it to a file server in a third site. The vSphere Content Library has its own built-in native replication mechanism which allows you for publishing and subscribing the libraries between two different vCenter servers. You can leverage this option for saving the backup data out of the source site. For more information about backing up data out of the source site, see VMware vSphere Virtual Machine documentation.
