Answer:
Data De-duplication
Explanation:
Data De-duplication is a feature that can help reduce the impact of redundant data on storage costs.
When enabled, Data De-duplication optimizes free space on a volume by examining the data on the volume by looking for duplicated portions on the volume. Duplicated portions of the volume's data set are stored once and are (optionally) compressed for additional savings.
Data De-duplication optimizes redundancies without compromising data fidelity or integrity.
