backupId

You can set the BackupId parameter to the backup set ID of the source instance. The system uses the data stored in the backup set to create an instance. You can call the DescribeBackups operation to query backup set IDs. If the source instance is a cluster instance, set the BackupId parameter to the backup set IDs of all shards of the source instance, separated by commas (,). If your instance is a cloud-native cluster instance, we recommend that you use DescribeClusterBackupList to query the backup set ID of the cluster instance. Then, set the ClusterBackupId request parameter to the backup set ID to clone the cluster instance. This eliminates the need to specify the backup set ID of each shard.
