Protection of the virtual infrastructure is an essential key point for every administrator, to limit potential services disruption.

The chapter covered how to protect ESXi hosts with a backup of the host's configuration to quickly restore a failed ESXi with minimal downtime. You just need a fresh installation of the ESXi host and to restore the configuration from the backup.

Another important key point to consider to avoid potential issues in case of failure is the backup of the vCSA. If the vCenter Server fails, vSphere features, such as vMotion and DRS, are no longer available and VM on production is not protected from potential host failures. This chapter explained how to protect the vCSA with the available backup options to quickly restore vCenter Server functionality, limiting service disruption.

Virtual servers are the most critical components of an infrastructure, since they provide services to the business. A suitable protection of VM is therefore required to ensure data protection and BC. The chapter provided a general overview of some backup solutions available in the market that protect virtual environments. Hyper-scale technology is quite a new solution that reduces the management of the workload's protection, providing appliances that are ready to go.
