Deep dive
How does DPM do efficient protection?
Protecting virtual hosts
Demo
How Microsoft IT uses DPM
Questions and Answers
Customer Needs & Requirements
• Need for Speed – Fast & Reliable Recoveries• Today, recovery is slow, unreliable and painful
• Data protection is labor intensive & error-prone
• 24x7 Businesses – No Backup Window• Backup is too complex, slow, and inefficient
• Tape inconvenience and unreliability is # 1 challenge
• Application downtime is not an option to get application consistency
• Simplify & Save – Easy to Buy & Use • Current backup products are too complex, costly
• Branch office data protection is cumbersome
• IT budget remains flat but data keeps growing – need to do more with less.
