Question

Quizplus · Accepted Answer

High availability is generally achieved through redundant systems, which means having multiple copies of critical components in order to ensure that if one fails, there is a backup ready to take its place. This can include things like redundant servers, power supplies, network connections, and more. Full backups can be a component of a high availability strategy, but they are not the primary way of achieving it. Fault tolerance and testing are also important, but again, they are not the primary way of achieving high availability.
