Disaster Recovery in the Same Region for Deployments Using Installed PostgreSQL

The procedure for performing Disaster Recovery (DR) in the same region for deployments using an installed PostgreSQL repository is identical to the process used for bundled PostgreSQL, except for the following additional steps and considerations.

• Install PostgreSQL on the Node: Before executing the disaster recovery script, install the PostgreSQL service on the target node by running the Kyvos-provided installation script:

  configure-postgres16.sh

  This script must be executed using sudo privileges.

• Match Database Configuration: Ensure that the username, password, port, and database names for the installed PostgreSQL service are identical to those used in the previous deployment for which disaster recovery is being performed.

• Password Consistency: If the current passwords for the Kyvos Manager and Kyvos repositories differ from their previous (non-default) values, update them to match the exact passwords used in the earlier deployment before running the disaster recovery script.
