Backing Up and Redeploying a Cluster
gsctl supports exporting the cluster to a backup image, and then redeploying to a clean directory from the backup file. The backup image includes the machines, product versions, cluster configuration, and services. Data is NOT backed up; this includes anything that may have been saved to disk such as custom Apache Zeppelin web notebooks.
The backup image contains the following:
- cluster.yaml file
- gsctl.yaml file
- Services (JSONs)
To back up a cluster image:
Type the following command to create a backup file with the tmp directory as the target. If you don't specify a target, the backup file is saved in the default directory where the gsctl.jar file is located.
export --target /tmp
This creates a backup file with the name of the cluster (<cluster-name>.backup).
To re-deploy a cluster image from a backup file:
Starting from an empty folder, type the following command. Replace the cluster-name placeholder text with the name of your actual backup file.
This deploys the backed-up cluster image, which is ready to be populated.
