How to create a backup
This guide contains recommended steps and useful commands for creating and managing backups to ensure smooth restores.
Prerequisites
- A cluster with at least three nodes deployed
- Access to an S3-compatible storage
- Configured settings for the S3-compatible storage
Summary
- Save your current cluster credentials, as you’ll need them for restoring
- Create a backup
- List backups to check the availability and status of your backups
Save your current cluster credentials
For security reasons, charm credentials are not stored inside backups. So, if you plan to restore to a backup at any point in the future, you will need the new user password as well as certificates/keys for your existing cluster.
You can retrieve the credentials of the admin user with the following command:
juju run opensearch/leader get-password

Create a backup
Once you have a three-node cluster with configurations set for S3 storage, check that Charmed OpenSearch is active and idle with juju status.
Once Charmed OpenSearch is active
and idle
, you can create your first backup with the create-backup
command:
juju run opensearch/leader create-backup
Running operation 333 with 1 task

backup-id: "2024-04-25T21:16:26Z"
status: Backup is running.
List backups
You can list your available, failed, and in progress backups by running the list-backups
command:
juju run opensearch/leader list-backups
Running operation 335 with 1 task
- task 336 on unit-opensearch-0
