Stay organized with collections Save and categorize content based on your preferences.

Starts creating a new Cloud Spanner Backup. The returned backup long-running operation will have a name of the format projects//instances//backups//operations/ and can be used to track creation of the backup. The metadata field type is CreateBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the creation and delete the backup. There can be only one pending backup creation per database. Backup creation of different databases can run concurrently.

This method waits—the workflow execution is paused—until the operation is complete, fails, or times out. The default timeout value is 1800 seconds (30 minutes) and can be changed to a maximum value of 31536000 seconds (one year) for long-running operations using the connector_params field. See the Connectors reference.

The connector uses polling to monitor the long-running operation, which might generate additional billable steps. For more information about retries and long-running operations, refer to Understand connectors.

The polling policy for the long-running operation can be configured. To set the connector-specific parameters (connector_params), refer to Invoke a connector call.

Arguments

Parameters
`parent`	`string` Required. The name of the instance in which the backup will be created. This must be the same instance that contains the database the backup will be created from. The backup will be stored in the location(s) specified in the instance configuration of this instance. Values are of the form `projects//instances/`.
`backupId`	`string` Required. The id of the backup to be created. The `backup_id` appended to `parent` forms the full backup name of the form `projects//instances//backups/`.
`encryptionConfig.encryptionType`	`enum` Required. The encryption type of the backup.
Enum type. Can be one of the following:
`ENCRYPTION_TYPE_UNSPECIFIED`	Unspecified. Do not use.
`USE_DATABASE_ENCRYPTION`	Use the same encryption configuration as the database. This is the default option when encryption_config is empty. For example, if the database is using `Customer_Managed_Encryption`, the backup will be using the same Cloud KMS key as the database.
`GOOGLE_DEFAULT_ENCRYPTION`	Use Google default encryption.
`CUSTOMER_MANAGED_ENCRYPTION`	Use customer managed encryption. If specified, `kms_key_name` must contain a valid Cloud KMS key.

`encryptionConfig.kmsKeyName`	`string` Optional. The Cloud KMS key that will be used to protect the backup. This field should be set only when encryption_type is `CUSTOMER_MANAGED_ENCRYPTION`. Values are of the form `projects//locations//keyRings//cryptoKeys/`.
`body`	`object (Backup)` Required.

Raised exceptions

Exceptions
`ConnectionError`	In case of a network problem (such as DNS failure or refused connection).
`HttpError`	If the response status is >= 400 (excluding 429 and 503).
`TimeoutError`	If a long-running operation takes longer to finish than the specified timeout limit.
`TypeError`	If an operation or function receives an argument of the wrong type.
`ValueError`	If an operation or function receives an argument of the right type but an inappropriate value. For example, a negative timeout.
`OperationError`	If the long-running operation finished unsuccessfully.
`ResponseTypeError`	If the long-running operation returned a response of the wrong type.

Response

If successful, the response contains an instance of Operation.
