Detailed explanation-2: -Data deduplication is a process that eliminates excessive copies of data and significantly decreases storage capacity requirements. Deduplication can be run as an inline process as the data is being written into the storage system and/or as a background process to eliminate duplicates after the data is written to disk.

Detailed explanation-3: -Duplicate makes an exact copy of a disk or folder (source volume) and saves it to another disk or folder (destination volume) of your choice. It is much like making a “drag and drop” copy of data to another folder or disk. You can access the duplicated files simply by double clicking the destination folder or disk.

Detailed explanation-4: -Data redundancy ensures an organization can provide continued operations or services in the event something happens to its data–for example, in the case of data corruption or data loss. The concept applies to areas such as databases, computer memory and file storage systems.
