A customer is experiencing rapid data growth and requires more backup data to be available online. Which technology could benefit the customer?
A. deduplication
B. wide striping
C. snapshots
D. tiering
Correct Answer: A
Explanation/Reference:
Data deduplication is a technique for reducing the amount of storage space an organization needs to save its data. In most organizations, the storage systems contain duplicate copies of many pieces of data.
Deduplication eliminates these extra copies by saving just one copy of the data and replacing the other copies with pointers that lead back to the original copy. Companies frequently use deduplication in backup and disaster recovery applications, but it can be used to free up space in primary storage as well.
