IP Expo 2009 - How To Backup and Protect Your Data in a Virtual Environment


Published on

Are you still using traditional backup methods in your virtual environment? If so, you know these methods can create resource contention and capacity issues that eat up the cost-savings you were hoping to realize from your virtual infrastructure. Traditional backup is not efficient or effective in a virtual environment. You need an evolutionary shift in your backup strategy. You need EMC’s next generation backup technologies for your VMware environment.

  3. 3. VMware Environment:Business Problem and the Required Solution<br />Business Problem<br />Backup challenges limiting VMware ROI <br />Not meeting VMware consolidation goals or backup and recovery SLAs<br />Higher costs & increased Ops/Mgmt<br />Technical Description<br />Traditional backup processes cause backup bottlenecks<br />Extended backup & restore times; limited server consolidation - increased hw spend<br />Solution Required – Efficient VMware Backup, Maximizing ROI<br />Minimal impact on virtual environment <br />Achieve or exceed consolidation and migration goals – 2X consolidation ratio!!<br />One step recovery; Flexible backup options for greater efficiency<br />Results if achieved<br />Increased server consolidation, lower HVAC/Floor space<br />Lower operational costs, fewer host servers required<br />Operational Mgmt Efficiency – greater TB’s per FTE, one-step recovery (file or image)<br />
