One of Red Hat’s customers has configured OpenShift’s log store to send a copy of various monitoring data to an external Elasticsearch cluster. Due to a problem that occurred in this customer’s environment, where part of the data from its external Elasticsearch cluster was lost, it was necessary to develop a way to copy the missing data, through a backup and restore process.
There are several ways to make backups as well as direct data transfers from one Elasticsearch Cluster to another, which allows good flexibility to meet different scenarios. We will see some of them in detail in this article.
