Administrar copias de seguridad

En esta página se ofrece información sobre las operaciones de copia de seguridad de Spanner. Para obtener más información sobre las copias de seguridad, consulta el artículo Introducción a las copias de seguridad.

Antes de empezar

  • Para obtener los permisos que necesitas para gestionar las copias de seguridad, pide a tu administrador que te conceda los siguientes roles de gestión de identidades y accesos en la instancia:

  • En los ejemplos de la CLI gcloud de esta página se dan por supuestos los siguientes aspectos:

Copiar una copia de seguridad

Consola

  1. En la Google Cloud consola, ve a la página Instancias de Spanner.

    Ir a Instancias

  2. Haz clic en la instancia que contiene la base de datos que quieres copiar.

  3. Haz clic en la base de datos.

  4. En el panel de navegación, haz clic en Copia de seguridad o restauración.

  5. En la tabla Copias de seguridad, selecciona Acciones en la copia de seguridad que quieras y haz clic en Copiar.

  6. Rellena el formulario. Para ello, elige una instancia de destino, proporciona un nombre y selecciona una fecha de vencimiento para la copia de seguridad.

  7. Haz clic en Copiar.

Para comprobar el progreso de una operación de copia, consulta Comprobar el progreso de la operación.

Si la operación tarda demasiado, puedes cancelarla. Para obtener más información, consulta Cancelar una operación de instancia de larga duración.

gcloud

Puedes copiar una copia de seguridad en otra instancia del mismo proyecto o en otra instancia de otro proyecto.

Copiar una copia de seguridad en el mismo proyecto

Si decides copiar la copia de seguridad en otra instancia del mismo proyecto, debes crear una instancia (o tener una preparada) para la copia de seguridad. No puedes crear una instancia como parte de la operación de copia de seguridad. Además, el tiempo de vencimiento de la copia de seguridad debe ser de al menos seis horas a partir del momento en que se procese la solicitud de copia actual y de un máximo de 366 días después del create_time de la copia de seguridad de origen.

Antes de usar los datos de los comandos que se indican a continuación, haz los siguientes cambios:

  • PROJECT_ID: el ID del proyecto.
  • SOURCE_INSTANCE_ID: el ID de la instancia de Spanner de origen.
  • SOURCE_DATABASE_ID: el ID de la base de datos de Spanner de origen.
  • SOURCE_BACKUP_NAME: nombre de la copia de seguridad de Spanner.
  • DESTINATION_INSTANCE_ID: el ID de la instancia de Spanner de destino.
  • DESTINATION_BACKUP_NAME: el nombre de la copia de seguridad de Spanner de destino.
  • EXPIRATION_DATE: la marca de tiempo de la fecha de vencimiento.
  • ENCRYPTION_TYPE: el tipo de cifrado de la copia de seguridad creada. Los valores válidos son USE_CONFIG_DEFAULT_OR_BACKUP_ENCRYPTION, GOOGLE_DEFAULT_ENCRYPTION o CUSTOMER_MANAGED_ENCRYPTION. Si usas CUSTOMER_MANAGED_ENCRYPTION, debes especificar un kmsKeyName.

Ejecuta el siguiente comando:

Linux, macOS o Cloud Shell

Copiar una copia de seguridad en otro proyecto

Si decides copiar la copia de seguridad en otro proyecto, debes tener otro proyecto con su propia instancia listo para la copia de seguridad. No puedes crear un proyecto como parte de la operación de copia de seguridad. Además, el tiempo de vencimiento de la copia de seguridad debe ser de al menos seis horas a partir del momento en que se procese la solicitud de copia actual y de un máximo de 366 días después de la copia de seguridad de origen create_time.

Antes de usar los datos de los comandos que se indican a continuación, haz los siguientes cambios:

  • SOURCE_PROJECT_ID: el ID del proyecto de origen.
  • SOURCE_INSTANCE_ID: el ID de la instancia de Spanner de origen.
  • SOURCE_DATABASE_ID: el ID de la base de datos de Spanner de origen.
  • SOURCE_BACKUP_NAME: nombre de la copia de seguridad de Spanner.
  • DESTINATION_PROJECT_ID: el ID del proyecto de destino.
  • DESTINATION_INSTANCE_ID: el ID de la instancia de Spanner de destino.
  • DESTINATION_BACKUP_NAME: el nombre de la copia de seguridad de Spanner de destino.
  • EXPIRATION_DATE: la marca de tiempo de la fecha de vencimiento.

Comprobar el progreso de la operación

Consola

  1. En la Google Cloud consola, ve a la página Instancias de Spanner.

    Ir a Instancias

  2. Haga clic en la instancia que contiene la base de datos cuya operación de copia de seguridad quiere ver.

  3. Haz clic en la base de datos.

  4. En el panel de navegación, haz clic en Operaciones. En la página Operaciones se muestra una lista de las operaciones en curso.

gcloud

Usa gcloud spanner operations describe para comprobar el progreso de una operación.

  1. Obtén el ID de la operación:

    Antes de usar los datos de los comandos que se indican a continuación, haz los siguientes cambios:

    • INSTANCE_NAME: el nombre de la instancia de Spanner.
    • DATABASE_NAME: el nombre de la base de datos de Spanner.

    Ejecuta el siguiente comando:

    Linux, macOS o Cloud Shell

    gcloud spanner operations list --instance=INSTANCE_NAME \
--database=DATABASE_NAME --type=backup

    Windows (PowerShell)

    gcloud spanner operations list --instance=INSTANCE_NAME `
--database=DATABASE_NAME --type=backup

    Windows (cmd.exe)

    gcloud spanner operations list --instance=INSTANCE_NAME ^
--database=DATABASE_NAME --type=backup

    Deberías recibir una respuesta similar a la siguiente:

    Notas sobre el uso:

    • Para limitar la lista, especifica la marca --filter. Por ejemplo:

      • --filter="metadata.name:example-db" solo muestra las operaciones de una base de datos específica.
      • --filter="error:*" solo muestra las operaciones de copia de seguridad que no se han realizado.

      Para obtener información sobre la sintaxis de los filtros, consulta gcloud topic filters. Para obtener información sobre cómo filtrar operaciones de copia de seguridad, consulta el campo filter en ListBackupOperationsRequest.

    • La marca --type no distingue entre mayúsculas y minúsculas.

  2. Ejecuta gcloud spanner operations describe:

    Antes de usar los datos de los comandos que se indican a continuación, haz los siguientes cambios:

    • OPERATION_ID: el ID de la operación.
    • INSTANCE_NAME: el nombre de la instancia de Spanner.
    • DATABASE_NAME: el nombre de la base de datos de Spanner.

    Ejecuta el siguiente comando:

    Linux, macOS o Cloud Shell

    gcloud spanner operations describe OPERATION_ID \
--instance=INSTANCE_NAME \
--backup=BACKUP_NAME \

    Windows (PowerShell)

    gcloud spanner operations describe OPERATION_ID `
--instance=INSTANCE_NAME `
--backup=BACKUP_NAME `

    Windows (cmd.exe)

    gcloud spanner operations describe OPERATION_ID ^
--instance=INSTANCE_NAME ^
--backup=BACKUP_NAME ^

    Deberías recibir una respuesta similar a la siguiente:

Cancelar una operación de copia de seguridad

Consola

La Google Cloud consola no permite cancelar una operación de copia de seguridad. Sin embargo, puedes cancelar las operaciones que tarden demasiado con la CLI de Google Cloud, REST o la API RPC. Para obtener más información, consulta Cancelar una operación de instancia de larga duración.

gcloud

  1. Obtén el ID de la operación:

    Antes de usar los datos de los comandos que se indican a continuación, haz los siguientes cambios:

    • INSTANCE_NAME: el nombre de la instancia de Spanner.
    • DATABASE_NAME: el nombre de la base de datos de Spanner.

    Ejecuta el siguiente comando:

    Linux, macOS o Cloud Shell

    gcloud spanner operations list --instance=INSTANCE_NAME \
--database=DATABASE_NAME --type=backup

    Windows (PowerShell)

    gcloud spanner operations list --instance=INSTANCE_NAME `
--database=DATABASE_NAME --type=backup

    Windows (cmd.exe)

    gcloud spanner operations list --instance=INSTANCE_NAME ^
--database=DATABASE_NAME --type=backup

    Deberías recibir una respuesta similar a la siguiente:

    OPERATION_ID     DONE  @TYPE                 BACKUP          SOURCE_DATABASE       START_TIME                   END_TIME

    Notas sobre el uso:

    • Para limitar la lista, especifica la marca --filter. Por ejemplo:

      • --filter="metadata.name:example-db" solo muestra las operaciones de una base de datos específica.
      • --filter="error:*" solo muestra las operaciones de copia de seguridad que no se han realizado.

      Para obtener información sobre la sintaxis de los filtros, consulta gcloud topic filters. Para obtener información sobre cómo filtrar operaciones de copia de seguridad, consulta el campo filter en ListBackupOperationsRequest.

    • La marca --type no distingue entre mayúsculas y minúsculas.

  2. Usa gcloud spanner operations cancel para cancelar una operación de copia de seguridad.

    Antes de usar los datos de los comandos que se indican a continuación, haz los siguientes cambios:

    • OPERATION_ID: el ID de la operación.
    • INSTANCE_NAME: el nombre de la instancia de Spanner.
    • DATABASE_NAME: el nombre de la base de datos de Spanner.
    • BACKUP_NAME: nombre de la copia de seguridad de Spanner.

    Ejecuta el siguiente comando:

    Linux, macOS o Cloud Shell

    gcloud spanner operations cancel OPERATION_ID --instance=INSTANCE_NAME \
 --database=DATABASE_NAME --backup=BACKUP_NAME

    Windows (PowerShell)

    gcloud spanner operations cancel OPERATION_ID --instance=INSTANCE_NAME `
 --database=DATABASE_NAME --backup=BACKUP_NAME

    Windows (cmd.exe)

    gcloud spanner operations cancel OPERATION_ID --instance=INSTANCE_NAME ^
 --database=DATABASE_NAME --backup=BACKUP_NAME

Bibliotecas de cliente

En el siguiente código de ejemplo se crea una copia de seguridad, se cancela la operación de copia de seguridad y, a continuación, se espera hasta que la operación de copia de seguridad se done. Si la operación se ha cancelado correctamente, devuelve cancelTime y un mensaje de error. Si la operación de copia de seguridad se ha completado antes de que se cancelara, la copia de seguridad existe y puedes eliminarla.

Por ejemplo, para filtrar la lista de forma que solo se incluyan las copias de seguridad que aún se están creando, añade --filter="state:creating". Para obtener información sobre la sintaxis de los filtros, consulta gcloud topic filters. Para obtener información sobre cómo filtrar copias de seguridad, consulta el campo filter en ListBackupsRequest.

Bibliotecas de cliente

En el siguiente código de ejemplo se enumeran las copias de seguridad de una instancia determinada.

Puede filtrar la lista de copias de seguridad devueltas (por ejemplo, por nombre, hora de la versión o hora de vencimiento de la copia de seguridad) proporcionando una expresión de filtro. Para obtener información sobre la sintaxis de los filtros, consulta el parámetro filter en List Backups.

Eliminar una copia de seguridad

Cuando eliminas una copia de seguridad, Spanner libera el almacenamiento y todos los demás recursos asociados a esa copia.

Si eliminas una copia de seguridad que aún se está creando, Spanner también cancelará la operación de copia de seguridad de larga duración.

Si una copia de seguridad incremental más reciente depende de ella, es posible que al eliminar una copia de seguridad incremental no se libere espacio de almacenamiento. Para obtener más información, consulta el artículo Introducción a las copias de seguridad.
