Restore a Backup in a Clustered Environment
-------------------------------------------

In a clustered environment,  servers can allow for failures and can keep data intact, because
when a server fails, an automatic failover occurs. 

If all services are kept running and data remains accessible, a **backup restore**
would only be necessary in very specific scenarios.

Restoring a backup in a cluster would only be necessary in the following cases:

* Data Corruption (Bad Data)
* Losing the whole cluster - requiring a redeploy of new servers
