33 be selected for backup. Containers of virtual machines such as data centers, clusters and resource pools can also be selected for backup. When a virtual machine is added to the protected container, it is automatically backed up. The first time a virtual machine is backed up, all data blocks are imaged; from that point until the next full backup, only unique data segments are backed up, thereby ensuring that redundant data is not backed up, saving backup storage resources. Since VMware vSphere Data Protection is primarily agentless, it eliminates the overhead of installing an agent in every virtual machine. However, through the use of light-weight application agents it allows granular, object-level backup of mission-critical applications like Microsoft® Exchange Server, SQL Server and SharePoint on both virtualized and physical servers. This is the recommended way to backup these mission-critical applications, since the agents utilize the application's backup APIs to perform backups in a transaction-consistent manner. vSphere Data Protection Advanced can replicate backup data to another vSphere Data Protection Advanced appli- ance (or to EMC Avamar servers). Backup data can be repli- cated to offsite or disaster recovery locations in an encrypted, WAN-optimized manner; i.e. only unique data segments are compressed, deduplicated, encrypted and replicated minimizing network bandwidth consumption and helping make the data in-flight secure.
