Recovery of Kyvos cluster from Kyvos Manager

Kyvos Manager provides a dedicated interface for disaster recovery of all cloud clusters. The dedicated wizard provides a guided flow for performing disaster recovery across all cloud clusters. Disaster recovery applies to the following cases:

• Cross Region Disaster Recovery: Recover the cluster in a region other than the primary cluster's deployment region, which was impacted by a disaster.

• Same Region Disaster Recovery: Recover cluster in a same region in which primary cluster was deployed. The entire primary region is not impacted due to disaster rather few such resources got impacted due to any reason. Restoring of those resources is expected via performing disaster recovery within the same region.

Points to know

• From Kyvos 2026.3 onwards, for AWS, you can enable automated disaster recovery by configuring recovery mode to Auto in DR CFT inputs.
  For more details, see the section, Disaster Recovery on AWS.

• As a prerequisite, keep the following things handy during disaster recovery, depending on what is affected in your cluster.

  • New certificates are applicable if existing settings (domain/subdomain) are changed after recovery.

  • Get the new license by sending the license request file in case of production.

Auto Mode: Disaster recovery via Kyvos Manager for AWS

For AWS, disaster recovery can be performed in either Manual or Auto mode, depending on the recovery mode configured in the DR CFT inputs. In Auto mode, no user intervention is required. The system automatically executes the necessary recovery steps. If a failure occurs during automated execution, the system switches to Manual mode and automatically returns to Auto mode once the issue is resolved.

1. Log on to the Kyvos Manager portal.

2. When you log on to the restored Kyvos Manager, you will be automatically redirected to the Disaster Recovery page. The system is automatically executing the required recovery steps.

3. Click the Home icon to go to the Home page of Kyvos Manager. On this page, verify that all nodes are running after disaster recovery.
