Menduplikasi disk dengan clone

Dokumen ini memberikan informasi tentang cara kerja clone disk dan cara membuat clone disk. Cloning disk memungkinkan Anda membuat duplikat disk yang ada yang dapat langsung digunakan. Buat clone disk dalam skenario saat Anda ingin membuat salinan disk yang ada yang identik dan dapat langsung dilampirkan ke VM, seperti berikut:

Membuat lingkungan staging dengan menduplikasi data produksi untuk proses debug tanpa mengganggu produksi
Membuat salinan untuk verifikasi cadangan database
Memindahkan data disk non-boot ke project baru
Menduplikasi disk saat menskalakan VM

Untuk melindungi dari pemulihan dari bencana, cadangkan disk Anda dengan snapshot standar, bukan menggunakan clone disk. Untuk merekam konten disk secara berkala tanpa membuat disk baru, gunakan snapshot instan karena lebih hemat penyimpanan daripada clone. Untuk opsi perlindungan disk tambahan, lihat Opsi perlindungan data.

Sebelum memulai

Jika Anda belum melakukannya, siapkan autentikasi. Autentikasi adalah proses verifikasi identitas Anda untuk mengakses layanan dan API Google Cloud. Untuk menjalankan kode atau contoh dari lingkungan pengembangan lokal, Anda dapat mengautentikasi ke Compute Engine dengan memilih salah satu opsi berikut:

Select the tab for how you plan to use the samples on this page:
Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
gcloud
1. Install the Google Cloud CLI, then initialize it by running the following command:
  gcloud init
  Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.
2. Set a default region and zone.

Cara kerja cloning disk

Saat meng-clone disk, Anda membuat disk baru yang berisi semua data di disk sumber. Anda dapat membuat clone disk meskipun disk yang ada terpasang ke instance VM.

Jenis disk clone harus sama dengan disk sumber. Namun, Anda dapat mengubah properti pada clone, seperti ukuran disk. Anda juga dapat menghapus disk sumber tanpa berisiko menghapus clone.

Jenis disk yang didukung

Anda dapat membuat clone disk hanya untuk jenis disk berikut:

Persistent Disk: Semua jenis Persistent Disk
Google Cloud Hyperdisk: Hyperdisk Balanced, Hyperdisk Extreme, dan Hyperdisk Throughput

Pembatasan

Bergantung pada jenis disk, clone disk memiliki batasan berikut:

Batasan umum

Batasan berikut berlaku untuk clone dari semua jenis disk:

Jenis disk clone harus sama dengan disk sumber.
Anda tidak dapat membuat clone disk zonal dari disk zona yang ada di zona berbeda.
Ukuran clone minimal harus sama dengan ukuran disk sumber. Jika membuat clone menggunakan konsol Google Cloud, Anda tidak dapat menentukan ukuran disk, dan clone tersebut akan memiliki ukuran yang sama dengan disk sumber.
Jika Anda menggunakan kunci enkripsi yang disediakan pelanggan atau kunci enkripsi yang dikelola pelanggan untuk mengenkripsi disk sumber, Anda harus menggunakan kunci yang sama untuk mengenkripsi clone tersebut. Untuk informasi selengkapnya, lihat Membuat clone disk sumber yang dienkripsi.
Anda tidak dapat menghapus disk sumber saat clone-nya sedang dibuat.
Instance komputasi tempat disk sumber terpasang tidak akan dapat dinyalakan saat clone sedang dibuat.
Jika disk sumber ditandai untuk dihapus bersama dengan VM yang terpasang, Anda tidak dapat menghapus VM saat clone sedang dibuat.
Anda dapat membuat maksimal satu clone disk sumber tertentu atau clone-nya setiap 30 detik.
Anda dapat memiliki maksimal 1.000 clone disk secara bersamaan dari disk sumber tertentu atau clone-nya. Jika batas ini terlampaui, internalError akan muncul. Namun, jika Anda membuat clone disk dan menghapusnya nanti, clone disk yang telah dihapus tersebut tidak akan disertakan dalam batasan ini.
Setelah disk di-clone, setiap clone berikutnya dari disk tersebut atau clone-nya akan dihitung dalam batas 1.000 clone disk simultan untuk disk sumber asli, dan dihitung dalam batas pembuatan maksimal satu clone setiap 30 detik.
Jika membuat disk regional dengan meng-clone disk zona, Anda dapat meng-clone maksimal 1 TiB kapasitas setiap 15 menit, dengan batas permintaan burst sebesar 257 TiB.

Batasan untuk clone Persistent Disk

Clone disk untuk Persistent Disk memiliki batasan berikut:

Anda tidak dapat membuat clone disk zonal dari disk regional.
Untuk membuat clone disk regional dari disk sumber zona, salah satu zona replika clone disk regional harus cocok dengan zona disk sumber.
Setelah pembuatan, clone disk regional rata-rata dapat digunakan dalam waktu 3 menit. Namun, disk mungkin memerlukan waktu puluhan menit untuk direplikasi sepenuhnya dan mencapai status dengan tujuan titik pemulihan (RPO) mendekati nol.
Jika membuat disk zona dari image, Anda tidak dapat menggunakan disk zona tersebut untuk membuat clone disk regional.

Batasan untuk clone Google Cloud Hyperdisk

Anda dapat membuat clone disk hanya untuk volume Hyperdisk Balanced, Hyperdisk Extreme, dan Hyperdisk Throughput.

Pesan error

Jika Anda melebihi batas frekuensi clone, permintaan akan gagal dengan error berikut:

RATE LIMIT: ERROR: (gcloud.compute.disks.create) Could not fetch resource:
 - Operation rate exceeded for resource RESOURCE. Too frequent operations from the source resource.

Membuat clone disk

Bagian ini menjelaskan cara menduplikasi disk yang ada dan membuat clone disk.

Untuk mengetahui langkah-langkah mendetail, bergantung pada jenis pembuatan clone disk, lihat salah satu bagian berikut dalam dokumen ini:

Membuat clone disk zona
Membuat clone disk regional dari disk zona
Membuat clone disk sumber terenkripsi

Izin yang diperlukan untuk langkah ini

Untuk melakukan tugas ini, Anda harus memiliki izin berikut:

compute.disks.create pada project
compute.disks.useReadOnly pada disk sumber

Membuat clone disk zonal

Anda dapat membuat clone disk zonal dari disk yang ada di zona yang sama dengan disk sumber menggunakan Konsol Google Cloud, Google Cloud CLI, atau REST.

Konsol

Di konsol Google Cloud, buka halaman Disks.

Buka Disk
Dalam daftar disk, buka disk yang ingin Anda clone.
Di kolom Actions, klik tombol menu dan pilih Clone disk.

Di panel Clone disk yang muncul, lakukan hal berikut:
1. Di kolom Name, tentukan nama untuk disk yang di-clone.
2. Untuk Location, pastikan Single zone dipilih.
3. Di bagian Properties, tinjau detail lain untuk disk yang di-clone.
4. Untuk menyelesaikan pembuatan disk yang di-clone, klik Buat.

gcloud

Untuk meng-clone disk sumber zonal dan membuat disk zonal baru, jalankan perintah disks create dan tentukan flag --source-disk:

gcloud compute disks create TARGET_DISK_NAME \
    --description="cloned disk" \
    --source-disk=projects/PROJECT_ID/zones/ZONE/disks/SOURCE_DISK_NAME

Ganti kode berikut:

TARGET_DISK_NAME: nama untuk disk baru.
PROJECT_ID: project ID tempat Anda ingin meng-clone disk.
ZONE: zona sumber dan disk baru.
SOURCE_DISK_NAME: nama disk sumber.

Terraform

Untuk membuat clone disk, gunakan resource google_compute_disk.

resource "google_compute_disk" "default" {
  name  = "disk-name1"
  type  = "pd-ssd"
  zone  = "us-central1-a"
  image = "debian-11-bullseye-v20220719"
  labels = {
    environment = "dev"
  }
  physical_block_size_bytes = 4096
}

REST

Untuk meng-clone disk sumber zonal dan membuat disk zonal baru, buat permintaan POST ke metode compute.disks.insert. Dalam isi permintaan, tentukan parameter name dan sourceDisk. Clone disk mewarisi semua properti yang dihilangkan dari disk sumber.

POST https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/disks

ZONE: zona sumber dan disk baru.
TARGET_DISK_NAME: nama untuk disk baru.
SOURCE_DISK_NAME: nama disk sumber

Membuat clone disk regional dari disk zona

Anda dapat membuat disk Persistent Disk regional baru dengan meng-clone volume Persistent Disk zona yang ada. Untuk memigrasikan disk zona ke disk regional, Google merekomendasikan opsi ini, bukan membuat snapshot disk zona dan memulihkan snapshot ke disk regional baru.

Konsol

Di konsol Google Cloud, buka halaman Disks.

Buka Disk
Dalam daftar disk, buka volume Persistent Disk zona yang ingin Anda clone.
Di kolom Actions, klik tombol menu dan pilih Clone disk.

Di panel Clone disk yang muncul, lakukan hal berikut:
1. Di kolom Name, tentukan nama untuk disk yang di-clone.
2. Untuk Location, pilih Regional, lalu pilih zona replika sekunder untuk disk regional baru yang di-clone.
3. Di bagian Properties, tinjau detail lain untuk disk yang di-clone.
4. Untuk menyelesaikan pembuatan disk yang di-clone, klik Buat.

gcloud

Untuk membuat clone disk regional dari disk zona, jalankan perintah gcloud compute disks create dan tentukan parameter --region dan --replica-zones.

gcloud compute disks create TARGET_DISK_NAME \
  --description="zonal to regional cloned disk" \
  --region=CLONED_REGION \
  --source-disk=SOURCE_DISK_NAME \
  --source-disk-zone=SOURCE_DISK_ZONE \
  --replica-zones=SOURCE_DISK_ZONE,REPLICA_ZONE_2 \
  --project=PROJECT_ID

Ganti kode berikut:

TARGET_DISK_NAME: nama untuk clone disk regional baru.
CLONED_REGION: region disk sumber dan disk yang di-clone.
SOURCE_DISK_NAME: nama disk zona yang akan di-clone.
SOURCE_DISK_ZONE: zona untuk disk sumber. Ini juga akan menjadi zona replika pertama untuk clone disk regional.
REPLICA_ZONE_2: zona replika kedua untuk clone disk regional baru.
PROJECT_ID: project ID tempat Anda ingin meng-clone disk.

Terraform

Untuk membuat clone disk regional dari disk zona, secara opsional Anda dapat membuat snapshot disk zona, lalu meng-clone snapshot tersebut. Untuk melakukannya, gunakan referensi berikut:

resource "google_compute_region_disk" "regiondisk" {
  name                      = "region-disk-name"
  snapshot                  = google_compute_snapshot.snapdisk.id
  type                      = "pd-ssd"
  region                    = "us-central1"
  physical_block_size_bytes = 4096
  size                      = 11

  replica_zones = ["us-central1-a", "us-central1-f"]
}

REST

Untuk membuat clone disk untuk disk sumber terenkripsi CMEK, buat permintaan POST ke metode compute.disks.insert dan berikan kunci enkripsi disk sumber menggunakan properti kmsKeyName. Jika Anda menggunakan kunci yang digabungkan RSA, gunakan metode versi beta.

POST https://compute.googleapis.com/compute/v1/projects/PROJECT_ID/zones/ZONE/disks

{
  "name": "TARGET_DISK_NAME"
  "sourceDisk": "projects/PROJECT_ID/zones/ZONE/disks/SOURCE_DISK_NAME"
  "diskEncryptionKey": {
    "kmsKeyName": "projects/KMS_PROJECT_ID/locations/REGION/keyRings/KEY_RING/cryptoKeys/KEY"
  },
}

Ganti kode berikut:

PROJECT_ID: project ID tempat Anda ingin meng-clone disk.
ZONE: zona sumber dan disk baru.
TARGET_DISK_NAME: nama untuk disk baru.
SOURCE_DISK_NAME: nama disk sumber.
KMS_PROJECT_ID: project ID untuk kunci enkripsi.
REGION: region kunci enkripsi.
KEY_RING: key ring kunci enkripsi.
KEY: nama kunci enkripsi.
