Backing up vSphere guests
Unlike traditional backup tools designed to work with physical machines, PPR can operate at the virtualization layer and directly employ the VMware snapshot mechanism to do backups. It doesn’t need an agent on a target virtual machine to create its point-in-time copy including its configuration, operating system, apps, etc. This approach significantly enhances the backup performance, while minimizing the load on target machines and the hypervisor during the process. Besides, there’s no need to provide credentials for every guest to do backups.
