1 EXECUTIVE SUMMARY As compute servers become more and more powerful, customers are turning to software virtualization technologies that enable them to take advantage of the power provided by these servers. While these virtualization techniques increase the utilization of the server, backup considerations need to be kept in mind for any virtualization architecture (or design). NetApp and VMware have combined resources to keep this piece of data center design relatively simple, yet robust and scalable at the same time. By using NetApp SnapVault technology with VMware Virtual Infrastructure 3 software, customers can rely on secure, fast, and simple backups of their existing infrastructure. This technical report discusses how to implement NetApp SnapVault in a VMware virtual infrastructure environment.
