When you want to clone the backup, you can only clone it\nto a database cluster that is in the same Kubernetes cluster and uses the same\nnamespace as the source database cluster. For more information about creating a\nbackup, see [Back up and restore in\nKubernetes](/alloydb/omni/15.7.1/docs/backup-kubernetes).\n\nIf you want to clone the backup to another database cluster in a\nstandalone server environment or in a different Kubernetes environment especially for disaster recovery, then you must use the `pgBackRest` configurations and\ncommands. The backup and restore method for both environments uses `pgBackRest`\nas the underlying backup and restore solution.\n\nThe following terms are used throughout the subsequent sections that explain how\nto clone a database cluster:\n\nSource database cluster\n: An AlloyDB Omni\n database cluster where the backup exists. This backup is cloned on other\n database clusters in a standalone server environment\n or a Kubernetes environment.\n\nTarget database cluster\n: A database cluster in the Kubernetes\n environment where the backup of the source database cluster is cloned.\n\nTarget server\n: A database cluster in the standalone server\n environment where the backup of the source database cluster is cloned.\n\nSupported backup and restore combinations\n-----------------------------------------\n\nBecause the backup of your AlloyDB Omni database cluster can be\nstored either locally or in a Cloud Storage bucket, the following backup and\nrestore combinations are supported:\n\n- [Clone a database cluster in Kubernetes using a Cloud Storage backup](/alloydb/omni/15.7.1/docs/kubernetes-dr-backup-k8-gcs)\n- [Clone a database cluster in Kubernetes using a local backup](/alloydb/omni/15.7.1/docs/kubernetes-dr-backup-k8-local)\n- [Clone a database cluster in a single server using a Cloud Storage backup](/alloydb/omni/15.7.1/docs/kubernetes-dr-backup-singleserver-gcs)\n- [Clone a database cluster in a single server using a local backup](/alloydb/omni/15.7.1/docs/kubernetes-dr-backup-singleserver-local)"]]
