Failback option
The Failback option determines the behavior when a failed encryption engine is restarted. When
the first encryption engine comes back online, the encryption group’s failback setting (auto or
manual) determines how the encryption engine resumes encrypting and decrypting traffic to its
encryption targets.
• In auto mode, when the first encryption engine restarts, it automatically resumes encrypting
and decrypting traffic to its encryption targets.
• In manual mode, the second encryption engine continues handling the traffic until you
manually invoke failback using the CLI or Management application, or until the second
encryption engine fails. When the encryption engine recovers, it can automatically fail back its
Crypto Target containers if the second encryption engine is not hosting them.
