The benefits of server virtualization for consolidation as well as management transparency are becoming well understood as are the issues associated with protecting data in virtualized server environments. There are many options to meet different RTO and RPO requirements. Virtualized server environments or infrastructures have varying functionalities and interfaces for application aware integration to enable complete and comprehensive data protection with data and transactional integrity. A combination of tape and disk-based data protection, including archiving for data preservation, coupled with a data footprint reduction strategy can help to address PCFE or "green" while meeting other needs and issues. There is no time like the present to re-assess, re-architect and re-configure your data protection environment particularly if are planning on, or have already initiated a server virtualization initiative. The bottom line is that virtual server environments require real and physical data protection. After all, you can not go forward if you can not go back.
