Hi Dojo,

I have a single ElasticSearch node running on a remote Linux server. Is there a way that I can configure daily backups to a shared location?

Hi Jens,

I'm using the Standalone Elastic Backup Tool - DataMiner Dojo, which is shipped by default with most recent versions of DataMiner. As far as I know, the automatic backup procedure cannot be configured with Cube for remote nodes, but you can schedule a Windows task with the following commands.

1) First initialize the repository.

"C:\Skyline DataMiner\Tools\StandaloneElasticBackup.exe" init --host *IP* --repo *REPO* --path "/mnt/networkshare"

2) Take a backup:

"C:\Skyline DataMiner\Tools\StandaloneElasticBackup.exe" backup --host *IP* --repo *REPO*

Hi Jarno, When taking a backup it fails with below message. Do you have an idea what can be wrong?
2022-01-13 07:55:26|Backup failed with reason: Object reference not set to an instance of an object..

I had a look in Kibana by sending command GET /_snapshot/my_repository/_all and there the snapshot was successful. I notified the developer and more logging will be added to investigate in the future.
