Automatically deletes all incremental backups and creates a new full backup when the incremental backup limit is reached.
Automatically deletes the oldest full backup when the full backup limit is reached.
To run workflow provide the following arguments:
- volume_id – ID of the volume to back up.
- backup_name – Name of the backup.
- max_full_backups – Maximum number of full backups to keep.
- max_incremental_backups – Maximum number of incremental backups to keep per full backup.

Running Mistral Workflow Using Horizon

Log in to the Horizon Dashboard.
Navigate to Workflows → Workflows.
Find the workflow you want to run (e.g., cinder_volume_backup_full, cinder_volume_backup_full_incremental, or cinder_volume_backup_rotation).
In the Actions column, click "Execute" next to the desired workflow.
In the Parameters field, enter the required arguments.

To use the openstack workflow command, you need to install the python-mistralclient library:

...

Code Block
openstack workflow execution create cinder_volume_backup_rotation \ '{"volume_id":"<volume_id>", "backup_name":"bkp1", "max_full_backups":2, "max_incremental_backups":5}'

Navigate to Workflows → Workflow Executions.
The status of the workflow will be displayed under the State column:
- SUCCESS – Workflow completed successfully.
- RUNNING – Workflow is still executing.
- FAILED – Workflow execution failed (check logs for details).
