Planned Failover for Azure Storage is a feature that allows controlled failover of storage accounts to their secondary region.Planned Failover ensures that the secondary region has a full replica of the data before failover, eliminating data loss.The failover process can be initiated through the portal or CLI and can be monitored using the same tools.Planned Failover is useful for failover testing, proactive failover, and when other resources fail but storage remains online.
