increases the availability of systems even when an isolated outage occurs, while provides the procedures to recover systems after a major failure.

Fault tolerance increases the availability of systems even when an isolated outage occurs, while disaster recovery provides the procedures to recover systems after a major failure.

Explanation:

There are two main properties of the system that should be under consideration while designing or deploying a system. fault tolerance and disaster recovery are the two important properties of the system.

In Fault tolerance, a system should be deigned as if some parts or components of the system will fail or not working properly, the system should work smoothly with the help of some alternate components or devices. This is called fault tolerance.

In Disaster recovery, a system should be able to overcome or restarts it working in case of some disaster. This feature enables the system to start its working after recovering from the disaster.
