backup and recovery for virtualized environments
DESCRIPTION
Virtualized environments running independently on a hypervisor always bring up the question of protection. Should you install the agent in the guest? Can you offload the backup to another host? Can you use hardware acceleration for backup? In this session we’ll address all those questions in the context of leading virtualization solutions such as vSphere, HyperV, or Citrix XEN. Then we’ll show you eight ways you can use HP Data Protector to protect your environment, including our market-leading functionality for hardware acceleration using Zero Downtime Backup.TRANSCRIPT

―Server virtualization has greatly reduced infrastructure costs, but it has also complicated backups‖
Forrester
96% of enterprises say server virtualization will have an impact on their backup strategy
87% consider virtual server backup as an important component of data protection
Server Virtualization creates new challenges in data protection

What needs to be protected ?
Virtual Environments
– VM information
• Protects the configuration details
• Enables Restore of VM image
• No Application data protection
– Application data
• Protects Application data in online
mode.
• Enables Automated recovery of
Application
– Disaster Tolerance
• Provides cross site protection
