Common concerns with backups are disk failure, lack of redundancy, and the necessity of future growth of disk capacity. Which backup method adresses these concerns and has multiple levels of use depending on how you want to prioritize features like performance, capacity, or reliability

RAID Array

Explanation:

Backups are needed in the IT industry to take care of some harm that can affect data resulting in its lose. RAID is the acronym for Redundant Array of Independent Disks. RAID combines multiple physical disks into a large virtual disk. It has different levels which range from 0, 1, 5, 6, and 10. RAID has a high degree of optimizing the data capacity of a backup device and its different levels prioritize features like performance, capacity, and reliability.

It also accommodates the future growth of disk capacity and reduces to the minimum the risk of data loss. It is very useful in ensuring data storage.
