Explanation

The various types of redundancy are as follows: - Hardware redundancy: it includes the installation of multiple processors, mirrored disks, multiple server farms, and RAIDS. - Process redundancy: It permits software to run simultaneously on multiple geographically distributed locations, with voting on results. It prevents attacks in which an attacker can get physical control of a machine, insert unauthorized software, and alter data. - Data redundancy: It allows the system to take backup on a permanent media at a regular time - Application redundancy: It needs at least two machines that can work on the same application. Application redundancy is the best way to make system infrastructure resilient against problems.
