The is a tool that can be use to perform standalone Elastic backup
https://docs.dataminer.services/user-guide/Reference/DataMiner_Tools/Standalone_Elastic_Backup_Tool.html
In case of an Elastic cluster with several nodes, does the backup need to be done on each node ? or the standalone tool perform a backup of the full cluster ?
Hey Bernard,
The standalone Elastic tool basically calls the _snapshot API on all the indices that are relevant for DataMiner. Elastic will then proceed to gather the data for the desired indices from the entire cluster and store it in the location that is linked to the rpo you passed as argument (see https://www.elastic.co/guide/en/elasticsearch/reference/6.8/modules-snapshots.html)
So the tool only needs to be executed on one node to have a backup of the full cluster.
