failback การใช้

"' Failback "'is the process of restoring a system, component, or service previously in a state of failure back to its original, working state, and having the standby system go from functioning back to standby.
You need a comprehensive failover / failback plan, showing all the possible failure modalities and how they're addressed, and you need to see a similarly comprehensive test plan that shows they've actually performed those failovers to show things really do survive, and that normal operation can then be resumed afterwards.
