3 Introduction With VMware vsphere 5.1 ( vsphere 5.1 ), VMware is releasing a new backup and recovery solution for virtual machines called vsphere Data Protection (VDP). This solution is fully integrated with VMware vcenter Server (vcenter Server) and provides agentless, disk-based backup of virtual machines to deduplicated storage. Benefits of VDP include the following: This paper presents an overview of the architecture, deployment, configuration, and management of VDP. Architectural Overview VMware vsphere 5.0. VDP supports the backing up of virtual machines on VMware vsphere ( vsphere ) versions 4.0 and higher. The following Web browsers are supported for configuration and management of VDP: machines, and as many as 10 VDP appliances can be deployed per vcenter Server instance. The Windows-based Web browser. TECHNICAL WHITE PAPER / 3

The retention policy can be defined in the following several ways: TECHNICAL WHITE PAPER / 5

6 Figure 3. VDP Retention Policy Configuration Virtual Machine Restore The restore of an entire virtual machine is performed using the Restore tab Client. The administrator can browse the list of virtual machines backed up by VDP and then select one or more since the selected restore point, and it recovers only those blocks. This reduces data transfer within the vsphere environment during a recovery operation and decreases recovery time. VDP automatically compares and the method resulting in the fastest restore time. This is useful in scenarios where the change rate since the selected restore point is very high and the overhead of a CBT analysis operation would be more costly than that of a full-image recovery. VDP intelligently determines which deployment method will result in the fastest full-image restore (CBT is not leveraged). Figure 4.

VDP also features a checkpoint-and-rollback protection system to help ensure that backup data is available for restoration when data loss occurs or disaster strikes.
