@balaji.ramaswamy I have one doubt, am using dremio in helm one coordinator and one executor , Will the data in my system crash when i upgrade the dremio version from v4.1.6 to latest …?

I believe you have used this helm charts

Upgrading dremio using helm chart will not destroy the data. Please find the upgrade instructions for a helm deployment in here. Please ensure you have a backup taken before proceeding with the upgrade.

You have to run the backup command inside the master/coordinator pod. Backup Instructions can be found here

ex: /opt/dremio/bin/dremio-admin backup -i -u user -p password -d /tmp/backup

Use kubectl cp command to copy the backup directory to local.

eg: kubectl cp dremio-master-0:/tmp/backup /my-local/dir
