The document discusses disaster recovery for mission critical applications. It notes challenges in ensuring application availability with data growth and budget pressures, while meeting regulatory requirements. It discusses using replication, snapshots, and continuous data protection to reduce recovery point objectives (RPO) from hours to minutes or less. EMC provides integrated solutions using technologies like Data Domain, Avamar, RecoverPoint, and VPlex to automate backup, replication, and recovery for applications.
