Starting with version 9.0 Neverfail Continuity Engine introduced a subscription-based licensing model managed through the Engine Licensing Server (ELS). Engine Management Service component (EMS), installed in the customer environment, securely communicates with ELS via SSL to request and apply license keys, ensuring that only supported versions of Continuity Engine are in use. This model also enables automated license renewals. In version 11, the system was enhanced to incorporate payment status, allowing a temporary 45-day license key to be issued if payment is pending. Upon payment completion, a full-term license is automatically applied. Additionally, version 17 introduced version validation, ensuring that only supported versions of Continuity Engine have access to licensing services, further improving the system’s reliability and control.
To activate a license, customers need to access their EMS web UI and navigate to Managed Engine Server > Actions > License Server > Online Licensing to request and apply the license key to the protected servers.
EMS must have ongoing connectivity to ELS in order get access to licensing services.
Offline environments requiring activation without internet access must follow the Self-Service Claim License Key process, which allows customers to manually generate and apply their license key without requiring direct communication with the ELS.
Term Subscription: A subscription with a fixed duration (years) that requires ongoing communication with the ELS to validate and renew the license periodically. If connectivity is lost for an extended period, licensing issues may occur.
For highly secured environments where connectivity to Internet is restricted, customers can use the Offline License Activation method by following the Self-Service Claim License Key process, which enables license retrieval without direct internet access.
Rental Subscription: Fixed duration. Monthly payment. Engine server using rental licensing requires ongoing connectivity to EMS and cannot be activated offline.
Important: If a subscription license expires without renewal, Continuity Engine real-time data replication feature is disabled. To restore functionality, a new license key must be generated and applied after renewal.
If a customer's payment status is pending at the time of subscription activation, the system will issue a temporary 45-day license key, ensuring business continuity while awaiting payment completion. Once the payment is confirmed, the license will automatically update to the full subscription period.
If the payment is fully completed at the time of activation, the system will generate a license key covering the entire purchased subscription term without requiring additional manual steps.
