Method: googleapis.spanner.v1.projects.instances.backups.copy

Starts copying a 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 copying of the backup. The operation is associated with the destination backup. The metadata field type is CopyBackupMetadata. The response field type is Backup, if successful. Cancelling the returned operation will stop the copying and delete the destination backup. Concurrent CopyBackup requests can run on the same source backup.

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 destination instance that will contain the backup copy. Values are of the form: projects//instances/.
body	object (CopyBackupRequest) 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.
