This API is used to start real-time migration, synchronization, and disaster recovery tasks in batches.

This API can be called only after all tasks are configured.
In the dual-active DR scenario, this operation can be performed only when the forward task status is INCRE_TRANSFER_STARTED and RPO&RTO is less than 60s. For backward tasks, this operation can be performed only after all tasks are configured. The parent task does not support this operation.
