The process of manual failover generally involves the following steps:
1. Identification of Issue: First, the issue with the primary email server must be identified. This could be through monitoring tools or alerts. 2. Decision to Failover: Once an issue is confirmed, the decision to initiate a failover is made by the responsible personnel. 3. Switching Servers: The DNS records or email routing configurations are manually updated to point to the backup server. 4. Testing: After switching, tests are conducted to ensure that the backup server is functioning correctly and emails are being delivered properly. 5. Monitoring: Continuous monitoring is performed to ensure that the backup server remains stable and effective.
