Question

What feature new to Windows Server 2012 provides the ability to find identical sets of data on a SAN based storage array and reduce the identical sets to a single instance, in order to reduce space

Answer 1

Data Deduplication

Step-by-step explanation:

In computing, data deduplication is a technique for eliminating duplicate copies of repeating data. This is also called single-instance storage.

Only applicable to Windows Server 2012 and newer versions, Data deduplication techniques ensure that only one unique instance of data is retained on storage media, such as disk, flash or tape.
