Abstract

A hard disk and methods for forwarding and acquiring data implemented by a hard disk. The hard disk includes: a storage module, configured to store data; an interaction interface, configured to implement data interaction between the hard disk and an external device; and a data control module, configured to control, by using the interaction interface, data interaction between the hard disk and the external device. In a process of performing backup implemented by the hard disk, a write data operation does not need to be performed on each backup hard disk when a server performs data backup by using the hard disk, which reduces operations performed by the server and releases resources of the server.

Claims

1. A hard disk, comprising:

a storage module configured to store data;

an interaction interface configured to implement data interaction between the hard disk and an external device; and

a data control module configured to control, using the interaction interface, the data interaction between the hard disk and the external device.

2. The hard disk according to claim 1, wherein the external device is an external computer.

3. The hard disk according to claim 1, wherein the external device is an external hard disk.

4. The hard disk according to claim 1, wherein the interaction interface is one of a Serial Attached Small Computer System (SAS) interface, a Serial Advanced Technology Attachment (SATA) interface, a Universal Serial Bus (USB) interface, and a wireless network interface.

5. The hard disk according to claim 1, wherein the interaction interface is an Internet Small Computer System Interface (iSCSI) and configured to receive, disassemble, assemble, and send iSCSI data.

6. The hard disk according to claim 1, wherein the data control module comprises a data forwarding unit configured to forward the data stored in the storage module to an external hard disk.

7. The hard disk according to claim 6, wherein the data forwarding unit further comprises:

a forwarding command receiving subunit configured to receive a forwarding request and forwarding configuration information;

a forwarding control subunit configured to control a data forwarding process; and

a forwarding status feedback subunit configured to feed back a state in which the hard disk forwards the data.

8. The hard disk according to claim 1, wherein the data control module comprises a data acquiring unit configured to acquire the data from the external device and store the data in the storage module.

9. A method for forwarding data implemented by a hard disk, comprising:

receiving the data;

storing the data; and

forwarding the data to an external device.

10. The method for forwarding the data implemented by the hard disk according to claim 9, further comprising a step of receiving a forwarding request and forwarding configuration information.

11. The method for forwarding the data implemented by the hard disk according to claim 9, further comprising a step of feeding back a state in which the hard disk forwards the data.

12. The method for forwarding the data implemented by the hard disk according to claim 9, wherein the data is forwarded to the external device at the same time when the data is stored.

13. The method for forwarding the data implemented by the hard disk according to claim 9, wherein the data is forwarded to the external device after the data is stored.

14. A method for acquiring data implemented by a hard disk, comprising:

receiving a data acquiring command;

establishing a data connection with an external device; and

acquiring the data.

15. The method for acquiring the data implemented by the hard disk according to claim 14, wherein the external device is an external hard disk.

16. The method for acquiring the data implemented by the hard disk according to claim 14, wherein the data acquiring command comprises a network address of the external device.
