Answer 2

Answer:

Data Redundancy refers to duplication of data

Explanation:

• Data redundancy is the practise of duplicating data.

• The situation of having the identical piece of data stored in two different locations is known as data redundancy and is created by databases or other data storage technologies.

• This can refer to two distinct areas in various software systems or platforms, or two distinct fields within a same database. Redundant data is essentially any data that has been repeated.
• For example, inconsistent duplicates of the same entry may be discovered in the same database, leading to unnecessary data redundancy. Accidental data redundancy can be a problem in terms of efficiency and costs if it results from inadequate coding or overly complex data storage procedures.
• Data redundancy can happen accidentally, however, it can also be done knowingly for backup and recovery purposes.
