Everything is about data mgmt now. Dedupe will be old school in 015. Along with that I see ILM practices taking hold. For example: instead of just using data retention policies, expiration, etc, I'm seeing HSM-like built in tools to give the data value, where metadata will be utilized to move the data around for disk tiering/archival. Data mgmt policies will be more departmental instead of enterprise-wide, giving way to more diverse ILM practices, and more stringent file retention policies.
