Saat Anda meng-clone cluster database, hanya data dari instance utama cluster database sumber yang di-clone ke instance utama cluster database atau server target.
Cluster database sumber adalah cluster database AlloyDB Omni tempat cadangan berada. Cadangan ini dikloning di cluster database lain dalam lingkungan server mandiri atau di lingkungan Kubernetes.
Cluster database target adalah cluster database di lingkungan
Kubernetes tempat cadangan cluster database sumber di-clone. Server target adalah cluster database di lingkungan server mandiri tempat cadangan cluster database sumber di-clone.
Untuk mencadangkan cluster database AlloyDB Omni, Anda mengonfigurasi lokasi cadangan di file manifes resource BackupPlan. Saat ingin meng-clone cadangan, Anda hanya dapat meng-clone-nya
ke cluster database yang berada di cluster Kubernetes yang sama dan menggunakan
namespace yang sama dengan cluster database sumber. Untuk mengetahui informasi selengkapnya tentang cara membuat
cadangan, lihat Mencadangkan dan memulihkan di Kubernetes.
Jika Anda ingin meng-clone cadangan ke cluster database lain di lingkungan server mandiri atau di lingkungan Kubernetes yang berbeda, terutama untuk pemulihan dari bencana, Anda harus menggunakan konfigurasi dan perintah pgBackRest. Metode pencadangan dan pemulihan untuk kedua lingkungan menggunakan pgBackRest
sebagai solusi pencadangan dan pemulihan yang mendasarinya.
Istilah berikut digunakan di seluruh bagian berikutnya yang menjelaskan cara meng-clone cluster database:
Cluster database sumber
Cluster database AlloyDB Omni tempat cadangan berada. Pencadangan ini dikloning di cluster database lain dalam lingkungan server mandiri atau lingkungan Kubernetes.
Cluster database target
Cluster database di lingkungan Kubernetes tempat cadangan cluster database sumber di-clone.
Server target
Cluster database di lingkungan server mandiri tempat cadangan cluster database sumber di-clone.
Kombinasi pencadangan dan pemulihan yang didukung
Karena pencadangan cluster database AlloyDB Omni Anda dapat disimpan secara lokal atau di bucket Cloud Storage, kombinasi pencadangan dan pemulihan berikut didukung:

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.
