Table 1. Parameter description
Parameter	Description
backup	Provide an elasticsearch snapshot repo via a shared volume
backup.enable	Enable/disable the Elasticsearch snapshot repo. Changing this value may require a restart/rebuild of the Elasticsearch cluster. If disabled it must not be deployed to a namespace which is backed up by Velero CSI snapshots.
backup.snapshotPVCStorageClass	Storage class to use for the shared volume used by the snapshot repo
backup.snapshotPVC	(Optional) override the PVC name
backup.sizeLimit	Size of the snapshot volume

Note:

To perform backup and restore backup.enable must be true in the CR section. This creates /workdir/snapshot_storage, on OpenSearch file system to host all the backups.
