Real-Time Replication & Failover SupportExtracts and repository data can change rapidly and even regular backups may not help you fully recover from a system failure. To help with this, distributed Tableau Server deployments now provide real-time content replication and failover support. You can configure one Tableau worker server to actively host the data extract and repository services, and another to be on standby. You can also set up email alerts so that youre notified of server failures or changes in status for your extract and repository services.
