Redundancy is a data protection method intended as a real-time fail-safe measure against hard drive failure. A common redundancy feature found in servers and NAS boxes to prevent data loss is RAID (which stands for Redundant Array of Independent Disks), which creates multiple copies of files across several hard drives. If one hard drive in the array fails, the other hard drives pick up the slack with (usually) no interruption. As adjectives the difference between redundant and duplicate is that redundant is superfluous; exceeding what is necessary while duplicate is being the same as another; identical this may exclude the first identical item in a series, but usage is inconsistent.

For example, you can place your database on two separate computers. If one computer goes down, the same data is available on the other computer.

Redundant data can also be useful and may even be required in order to satisfy service-level goals for performance, availability, and accessibility. It has been shown in the different representations of the same data by data warehouses, operational data stores, and business intelligence systems that redundant data is essential in providing new information.

Data redundancy is the repetition or superfluity of data. Data redundancy data is an common issue in computer data storage and database systems. Data redundancy definition Data redundancy in database means that some data fields are repeated in the database. This data repetition may occur either if a field is repeated in two or more tables or if Data redundancy is a condition that occurs within a database or data storage technology in which, you can find the same piece of data in two or more separate places. Whereas, data inconsistency is a condition that occurs between tables when we keep similar data in different formats in two different tables, or when matching of data between tables is a must. Redundant Data as the name suggests is data duplication.

This is useful for safety.
