You must have binary logging enabled, and a backup created since binary logging was enabled, before you can clone an instance. For more information and examples, see Cloning Instances.

  }
}

Property name	Value	Description
`kind`	`string`	This is always `sql#operation`.
`selfLink`	`string`	The URI of this resource.
`targetProject`	`string`	The project ID of the target instance related to this operation.
`targetId`	`string`	Name of the database instance related to this operation.
`targetLink`	`string`	The URI of the instance related to the operation.
`name`	`string`	An identifier that uniquely identifies the operation. You can use this identifier to retrieve the Operations resource that has information about the operation.
`operationType`	`string`	The type of the operation. Valid values are `CREATE`, `DELETE`, `UPDATE`, `RESTART`, `IMPORT`, `EXPORT`, `BACKUP_VOLUME`, `RESTORE_VOLUME`, `CREATE_USER`, `DELETE_USER`, `CREATE_DATABASE`, `DELETE_DATABASE` .
`status`	`string`	The status of an operation. Valid values are `PENDING`, `RUNNING`, `DONE`, `UNKNOWN`.
`user`	`string`	The email address of the user who initiated this operation.
`insertTime`	`datetime`	The time this operation was enqueued in UTC timezone in RFC 3339 format, for example `2012-11-15T16:19:00.094Z`.
`startTime`	`datetime`	The time this operation actually started in UTC timezone in RFC 3339 format, for example `2012-11-15T16:19:00.094Z`.
`endTime`	`datetime`	The time this operation finished in UTC timezone in RFC 3339 format, for example `2012-11-15T16:19:00.094Z`.
`error`	`nested object`	If errors occurred during processing of this operation, this field will be populated.
`error.errors[]`	`list`	The list of errors encountered while processing this operation.
`error.errors[].kind`	`string`	This is always `sql#operationError`.
`error.errors[].code`	`string`	Identifies the specific error that occurred.
`error.errors[].message`	`string`	Additional information about the error encountered.
`importContext`	`nested object`	The context for import operation, if applicable.
`importContext.kind`	`string`	This is always `sql#importContext`.
`importContext.fileType`	`string`	The file type for the specified uri. `SQL`: The file contains SQL statements. `CSV`: The file contains CSV data.
`importContext.uri`	`string`	Path to the import file in Cloud Storage, in the form `gs://bucketName/fileName`. Compressed gzip files (.gz) are supported when `fileType` is `SQL`. The instance must have write permissions to the bucket and read access to the file.
`importContext.database`	`string`	The target database for the import. If `fileType` is `SQL`, this field is required only if the import file does not specify a database, and is overridden by any database specification in the import file. If `fileType` is `CSV`, one database must be specified.
`importContext.csvImportOptions`	`object`	Options for importing data as CSV.
`importContext.csvImportOptions.table`	`string`	The table to which CSV data is imported.
`importContext.csvImportOptions.columns[]`	`list`	The columns to which CSV data is imported. If not specified, all columns of the database table are loaded with CSV data.
`exportContext`	`nested object`	The context for export operation, if applicable.
`exportContext.kind`	`string`	This is always `sql#exportContext`.
`exportContext.fileType`	`string`	The file type for the specified uri. `SQL`: The file contains SQL statements. `CSV`: The file contains CSV data.
`exportContext.uri`	`string`	The path to the file in Google Cloud Storage where the export will be stored. The URI is in the form `gs://bucketName/fileName`. If the file already exists, the requests succeeds, but the operation fails. If `fileType` is `SQL` and the filename ends with .gz, the contents are compressed.
`exportContext.databases[]`	`list`	Databases to be exported. MySQL instances: If `fileType` is `SQL` and no database is specified, all databases are exported, except for the `mysql` system database. If `fileType` is `CSV`, you can specify one database, either by using this property or by using the `csvExportOptions.selectQuery` property, which takes precedence over this property. PostgreSQL instances: Specify exactly one database to be exported. If `fileType` is `CSV`, this database must match the database used in the `csvExportOptions.selectQuery` property.
`exportContext.sqlExportOptions`	`object`	Options for exporting data as SQL statements.
`exportContext.sqlExportOptions.tables[]`	`list`	Tables to export, or that were exported, from the specified database. If you specify tables, specify one and only one database. For PostgreSQL instances, you can specify only one table.
`exportContext.csvExportOptions`	`object`	Options for exporting data as CSV.
`exportContext.csvExportOptions.selectQuery`	`string`	The select query used to extract the data.
`error.kind`	`string`	This is always `sql#operationErrors`.
`exportContext.sqlExportOptions.schemaOnly`	`boolean`	Export only schemas.
`importContext.importUser`	`string`	The PostgreSQL user for this import operation. PostgreSQL instances only.
`exportContext.sqlExportOptions.mysqlExportOptions`	`object`	Options for exporting from MySQL.
`exportContext.sqlExportOptions.mysqlExportOptions.masterData`	`integer`	Option to include SQL statement required to set up replication. If set to `1`, the dump file includes a CHANGE MASTER TO statement with the binary log coordinates. If set to `2`, the CHANGE MASTER TO statement is written as a SQL comment, and has no effect. All other values are ignored.
