Что передать
Проект, исходный и целевой кластеры, область копирования, расписание и срок хранения.

Оценки пользователей
Как использовать
Помогает администраторам настроить Backup for GKE для приложений, которые хранят состояние в Kubernetes. Охватывает расписание копирования, срок хранения, шифрование собственным ключом и восстановление в целевой кластер.
- Определите пространства имён и состав копии; для полной защиты явно включите данные томов и секреты.
- Подготовьте включение BackupRestore и планы копирования и восстановления, при необходимости задайте собственный ключ шифрования.
- Проверьте восстановление в непроизводственном кластере и выберите политику обработки конфликтов перед рабочим восстановлением.
Условия работы
- Нужны компонент gcloud beta и включённый BackupRestore; для снимков данных постоянных томов должен использоваться драйвер CSI GKE.
- Без явного включения данных томов и секретов копия содержит только конфигурацию.
- Перед любым восстановлением в производственный кластер обязательно явное подтверждение пользователя с описанием политики конфликтов и возможной перезаписи или удаления. Сначала восстановление проверяют вне производства.
- Скилл не предназначен для резервного копирования баз данных. Hyperdisk ML и Balanced High Availability поддерживаются начиная с GKE 1.33.1-gke.1959000.
Пример запроса после установки
Настрой Backup for GKE для пространства имён нашего приложения: сохраняй данные томов и секреты, а восстановление сначала подготовь в отдельном тестовом кластере.

# GKE Backup & Disaster Recovery
Protects stateful GKE workloads using Backup for GKE. Backup for GKE can capture
both Kubernetes resource metadata (manifests, configurations, and secrets) and
the underlying persistent volume (PV) data — but volume data and secrets are
**only** captured when the backup plan explicitly enables them (see the flags
below).
## CLI Reference
```bash
# Enable the BackupRestore addon (Slow cluster-level update)
gcloud container clusters update {cluster_name} \
--update-addons=BackupRestore=ENABLED --location={location} --quiet
# Create Backup Plan
gcloud beta container backup-restore backup-plans create {plan_name} \
--project={project_id} --location={location} \
--cluster=projects/{project_id}/locations/{location}/clusters/{cluster_name} \
--all-namespaces \
--include-volume-data --include-secrets \
--backup-retain-days={days} --cron-schedule="{cron}" --quiet
# Trigger Manual Backup
gcloud beta container backup-restore backups create {backup_name} \
--backup-plan={plan_name} --location={location} --quiet
# Create Restore Plan
gcloud beta container backup-restore restore-plans create {restore_plan_name} \
--location={location} \
--cluster=projects/{project_id}/locations/{location}/clusters/{target_cluster_name} \
--backup-plan=projects/{project_id}/locations/{location}/backupPlans/{source_backup_plan_name} \
--all-namespaces \
--cluster-resource-conflict-policy=use-existing-version \
--namespaced-resource-restore-mode=fail-on-conflict --quiet
# Execute Restore
gcloud beta container backup-restore restores create {restore_name} \
--restore-plan={restore_plan_name} --location={location} \
--backup=projects/{project_id}/locations/{location}/backupPlans/{source_backup_plan_name}/backups/{backup_name} \
--quiet
# Verify Restore Status
gcloud beta container backup-restore restores describe {restore_name} \
--restore-plan={restore_plan_name} --location={location}
```
> [!WARNING] **`--include-volume-data` and `--include-secrets` BOTH DEFAULT TO
> FALSE.** If you omit them, the backup plan silently produces **config-only
> backups** with no persistent volume snapshots and no Secrets. Always pass both
> flags explicitly when the goal is full workload protection.
Notes:
- The `backup-restore` command group requires the `gcloud beta` component
(`gcloud components install beta`).
- `--cluster` requires the full resource path
`projects/{project_id}/locations/{location}/clusters/{cluster_name}` (or
`projects/{project_id}/zones/{zone}/clusters/{cluster_name}` for zonal
clusters), not a bare cluster name.
- Restore plans require exactly one namespaced-resource scope flag:
`--all-namespaces`, `--selected-namespaces={ns1},{ns2}`,
`--excluded-namespaces=...`, `--selected-applications=...`, or
`--no-namespaces`.
## Restore Safety (CRITICAL)
A restore writes into a **live cluster** and, depending on the conflict policy,
can overwrite or delete existing resources:
- `--cluster-resource-conflict-policy=use-existing-version` keeps existing
cluster-scoped resources (safe default); `use-backup-version` **deletes**
the existing version first — deleting a CRD deletes all of its CRs.
- `--namespaced-resource-restore-mode=fail-on-conflict` aborts on any conflict
(safe default); `merge-skip-on-conflict` skips conflicting resources;
`merge-replace-on-conflict` and `merge-replace-volume-on-conflict`
**overwrite** existing resources or volumes; `delete-and-restore` **deletes
entire conflicting namespaces** (and all resources in them) before
restoring.
**Rules:**
1. Validate the restore in a non-production target cluster first.
2. Prefer the safe defaults (`use-existing-version` + `fail-on-conflict`)
unless the user explicitly needs to revert live resources.
3. **Always obtain explicit user confirmation before executing a restore into a
production cluster**, and state which conflict policy is in effect and what
it may overwrite or delete.
## Best Practices
1. **CMEK Encryption**: Encrypt backup plans using Customer-Managed Encryption
Keys:
`--encryption-key=projects/{project_id}/locations/{location}/keyRings/{ring}/cryptoKeys/{key}`.
2. **Scope**: Prefer backing up specific namespaces rather than the entire
cluster: `--selected-namespaces={ns1},{ns2}` (instead of
`--all-namespaces`).
3. **Application Consistency**: Recommend quiescing the database or pausing
application writes (e.g. using pre-backup hooks or database-specific tools)
prior to backups to ensure data integrity.
4. **CSI Volume Snapshots**: Ensure that stateful backups utilize GKE's CSI
(Container Storage Interface) driver for volume snapshots to capture
persistent volume data.
5. **Service Terminology**: Always explicitly refer to the service as **Backup
for GKE** in your response. This distinguishes it from the broader (but
complementary) Google Cloud **Backup and Disaster Recovery (DR)
Service**, ## Golden Path Backup Defaults
The recommended production golden path configuration for Backup for GKE:
- **Addon**: BackupRestore addon enabled
(`--update-addons=BackupRestore=ENABLED`).
- **Volume Inclusion**: `--include-volume-data` explicitly passed (enabled,
since the service default is false).
- **Secret Inclusion**: `--include-secrets` explicitly passed (enabled, since
the service default is false).
- **Retention**: Defined retention period (e.g. 30 days via
`--backup-retain-days=30`).
- **Encryption**: CMEK enabled (`--encryption-key=...`).
## Recent Changes
- **Cross-project backup and restore (GA)**: Backup plans can store backups in
a different project than the source cluster, and restore plans can target
clusters in a third project. Enables centralized backup projects (with
immutability/retention managed by a platform team) and cross-project
environment seeding without granting access to the source project.
- **Pricing change (effective 2026-03-02)**: The backup management fee moved
from **pod-based** to **NAMESPACE-based** pricing — charged per non-system
namespace in the most recent successful backup of each plan (system
namespaces like `kube-system` are excluded). Existing committed use discount
(CUD) holders keep pod-based management pricing until their commitment ends;
everyone else moves to the new model. See
https://cloud.google.com/products/backup-for-gke/pricing-changes.
- **Smart Scheduling**: RPO-driven backup scheduling as an alternative to
fixed cron schedules — pass `--target-rpo-minutes={minutes}` instead of
`--cron-schedule` when creating the backup plan (optionally with RPO
exclusion windows via `--exclusion-windows-file`).
- **Hyperdisk support**: Backup and restore of **Hyperdisk ML** and
**Hyperdisk Balanced High Availability** volumes is supported on GKE
clusters running **1.33.1-gke.1959000 and later** (Hyperdisk throughput,
extreme, and balanced types are also supported).
## Troubleshooting & Common Pitfalls (CRITICAL)
> [!IMPORTANT] **Slow Operations**: Enabling the BackupRestore addon
> (`--update-addons=BackupRestore=ENABLED`) triggers a slow Google Cloud control
> plane cluster update that takes several minutes. * **Rule**: **Do not run a
> terminal loop waiting for the GKE Backup addon to become active.** *
> **Action**: Provide the command to enable the addon, explain that the
> operation will proceed in the background, and immediately proceed to write the
> backup plan configs. Do not block.
