By default, Data Transmission Service (DTS) supports only data synchronization within the same country or region. If you want to synchronize data across borders such as from a region in the Chinese mainland to a region outside the Chinese mainland, you must apply for related permissions.

Note If you do not have the permissions to synchronize data across borders, you cannot select a destination region that resides in another country or region after you select a source region on the DTS buy page.

Usage notes

  • Make sure that you comply with related data security policies of the source and destination regions when you synchronize data across borders.
  • Before you perform cross-border data synchronization, you must read and agree to the Alibaba Cloud International Website Privacy Policy.
