EMC purchased data-protection and replication software maker Kashya for $153 million in cash to improve its network virtualization and continuous data protection (CDP) products. Robert Emsley, director of marketing for information management software at EMC, said Kashya’s disaster-recovery and replication technology will prop up Invista, which pulls storage from several devices into one pool to draw from. RecoverPoint triggers back-up and recovery tasks frequently throughout the day to ensure that data can be recovered at any point in time.
