백업 관리

이 페이지에서는 Spanner 백업 작업에 대한 정보를 제공합니다. 백업에 대한 자세한 내용은 백업 개요를 참조하세요.

시작하기 전에

백업을 관리하는 데 필요한 권한을 얻으려면 관리자에게 인스턴스에 대한 다음 IAM 역할을 부여해 달라고 요청하세요.
- 백업 만들기, 보기, 업데이트, 삭제: Cloud Spanner 백업 관리자(roles/spanner.backupAdmin)
- 백업 만들기 및 보기: Cloud Spanner 백업 작성자(roles/spanner.backupWriter)
참고: IAM 기본 역할도 백업을 관리할 수 있는 권한이 포함될 수 있습니다. 프로덕션 환경에서는 기본 역할을 부여하지 말아야 하지만 개발 환경 또는 테스트 환경에서는 부여해도 됩니다.
이 페이지의 gcloud CLI 예시에서는 다음 가정이 사용됩니다.
- gcloud CLI가 이미 Spanner에 사용하도록 설정되어 있습니다. Spanner에서 gcloud CLI를 처음 사용하는 경우 gcloud CLI를 사용하여 Spanner 시작하기를 참조하세요.
- 프로젝트에 gcloud CLI를 구성했습니다. 예를 들면 다음과 같습니다.
```
gcloud config set core/project PROJECT_ID
```

백업 복사

콘솔

Google Cloud 콘솔에서 Spanner 인스턴스 페이지로 이동합니다.

인스턴스로 이동
복사할 데이터베이스가 포함된 인스턴스를 클릭합니다.
데이터베이스를 클릭합니다.
탐색창에서 백업/복원을 클릭합니다.
백업 테이블에서 백업에 대한 작업을 선택하고 복사를 클릭합니다.
대상 인스턴스를 선택하고, 이름을 제공하고, 백업 복사본의 만료 날짜를 선택하여 양식을 작성합니다.
복사를 클릭합니다.

복사 작업의 진행 상황을 확인하려면 작업 진행 상황 확인을 참조하세요.

작업에 시간이 너무 오래 걸리는 경우 취소할 수 있습니다. 자세한 내용은 장기 실행 인스턴스 작업 취소를 참조하세요.

gcloud

동일한 프로젝트의 다른 인스턴스 또는 다른 프로젝트의 다른 인스턴스에 백업을 복사할 수 있습니다.

동일한 프로젝트의 백업 복사

백업을 동일한 프로젝트의 다른 인스턴스로 복사하도록 선택한 경우 복사된 백업을 위한 새 인스턴스를 만들거나 인스턴스를 준비해야 합니다. 백업 복사 작업 중에는 새 인스턴스를 만들 수 없습니다. 또한 백업 만료 시간은 현재 복사 요청이 처리된 시점부터 최소 6시간, 소스 백업 create_time 이후 최대 366일이어야 합니다.

아래의 명령어 데이터를 사용하기 전에 다음을 바꿉니다.

PROJECT_ID: 프로젝트 ID입니다.
SOURCE_INSTANCE_ID: 소스 Spanner 인스턴스 ID입니다.
SOURCE_DATABASE_ID: 소스 Spanner 데이터베이스 ID입니다.
SOURCE_BACKUP_NAME: Spanner 백업 이름입니다.
DESTINATION_INSTANCE_ID: 대상 Spanner 인스턴스 ID입니다.
DESTINATION_BACKUP_NAME: 대상 Spanner 백업 이름입니다.
EXPIRATION_DATE: 만료일 타임스탬프입니다.

다른 프로젝트의 백업 복사

백업을 다른 프로젝트에 복사하도록 선택한 경우 복사된 백업을 위해 자체 인스턴스가 준비된 다른 프로젝트가 있어야 합니다. 백업 복사 작업 중에는 새 프로젝트를 만들 수 없습니다. 만료 시간은 현재 복사 요청이 처리된 시점부터 최소 6시간, 소스 백업 create_time 이후 최대 366일이어야 합니다.

클라이언트 라이브러리

다음 코드 샘플은 기존 백업을 복사합니다. 백업을 다른 리전 또는 프로젝트의 인스턴스로 복사할 수 있습니다. 완료되면 샘플이 이름, 크기, 백업 상태, version_time과 같이 새로 생성된 복사된 백업에 대한 몇 가지 정보를 검색하고 출력합니다.

백업 작업 취소

콘솔

Google Cloud 콘솔은 백업 작업 취소를 지원하지 않습니다. 하지만 Google Cloud CLI, REST, RPC API를 사용할 때는 너무 오래 걸리는 작업을 취소할 수 있습니다. 자세한 내용은 장기 실행 인스턴스 작업 취소를 참조하세요.

아래의 명령어 데이터를 사용하기 전에 다음을 바꿉니다.

사용 참고사항:
- 목록을 제한하려면 --filter 태그를 지정합니다. 예를 들면 다음과 같습니다.
  - --filter="metadata.name:example-db"는 특정 데이터베이스의 작업만 나열합니다.
  - --filter="error:*"는 실패한 백업 작업만 나열합니다.
  필터 구문에 대한 자세한 내용은 gcloud topic filters를 참조하세요. 백업 작업 필터링에 대한 자세한 내용은 ListBackupOperationsRequest의 filter 필드를 참조하세요.
- --type 플래그는 대소문자를 구분하지 않습니다.
gcloud spanner operations cancel을 사용하여 백업 작업을 취소합니다.
아래의 명령어 데이터를 사용하기 전에 다음을 바꿉니다.
- OPERATION_ID: 작업 ID
- INSTANCE_NAME: Spanner 인스턴스 이름
- DATABASE_NAME: Spanner 데이터베이스 이름

클라이언트 라이브러리

다음 코드 샘플은 백업을 만들고 백업 작업 취소한 다음 백업 작업이 done이 될 때까지 대기합니다. 작업이 성공적으로 취소되었으면 cancelTime 및 오류 메시지를 반환합니다. 취소되기 전 백업 작업이 완료되었고 백업이 존재하면 이를 삭제할 수 있습니다.

목록을 제한하려면 --filter 태그를 지정합니다. 예를 들어 아직 작성 중인 백업만 포함하도록 목록을 필터링하려면 --filter="state:creating"을 추가합니다. 필터 구문에 대한 자세한 내용은 gcloud topic filters를 참조하세요. 백업 필터링에 대한 자세한 내용은 ListBackupsRequest의 filter 필드를 참조하세요.

클라이언트 라이브러리

다음 코드 샘플은 지정된 인스턴스의 백업을 나열합니다.

필터 표현식을 제공하여 반환된 백업 목록을 필터링할 수 있습니다(예: 이름, 버전 시간, 백업 만료 시간으로 필터링). 필터링 구문에 대한 내용은 Backups 나열의 filter 매개변수를 참조하세요.
