What is Failover vs Failback?

in today's unpredictable business environment, organizations face a wide range of disruptions either from cyberattacks and natural disasters to system failures and geopolitical conflicts. With Failover and failback, business can continue to function properly, even if the production site is affected by a disaster.

Failover: Failover is the process of automatically switching to a backup system when the primary system goes down. It switches operation from the main system to a backup in case of failure; this process is done either manually or automatically.  

Failback: Failback is the process of returning everything to normal once the primary system is fix and ready. After the outage, team restores the primary system making sure all the data and changes made during the failover are synchronized. This is important because running on the backup for too long can cause issues or vulnerability. Failback can be automatic or manual depending on the setup.
