A streamlined approach enables customers to retain management control over their data in a database-as-a-service (“DBaaS”) setting, by providing managed backup copies outside cloud service providers' sphere of control. An illustrative data storage management system provides control over performing backup operations to generate managed backup copies, storing managed backup copies, recovering managed backup copies in whole or in part, migrating managed backup copies, and migrating DBaaS instances. Management control also extends to choices of where to store the managed backup copies, whether on the same cloud computing platform as the source DBaaS, on a different cloud computing platform, and/or in a non-cloud data center.

A method for transmitting data includes a sending end device generating a first packet data convergence protocol (PDCP) protocol data unit (PDU), wherein the first PDCP PDU comprises type information, and the type information is used for indicating that the type of a first data packet in the first PDCP PDU is one of an Ethernet data packet, an Internet protocol (IP) data packet and an Ethernet data packet comprising an IP packet header.
