Embodiment 1

[0037] see figure 1 It is a flow chart of an embodiment of a solid state disk data backup method of the present invention.

[0038] The embodiment of the present invention adopts a dual-port SSD: the SSD has two data interfaces on the framework, the first data interface is used to send and receive data or commands from the host or storage server, the second data interface is used to connect the backup SSD, and the data passes through and backup The second data interface connected to the SSD for transmission. In this embodiment, the first data interface of the master disk is connected to the host computer, and the second data interface of the master disk is connected to the data interface of the backup disk.

[0039] The process is as follows:

[0040] Step 101, the main disk obtains the connection success information of the backup disk;

[0041] When the backup disk and the master disk are successfully connected through the data interface, the master disk can know that the...

Embodiment 2

[0046] see figure 2 It is the flowchart of the second embodiment of a kind of solid-state hard disk data backup method of the present invention;

[0047] Embodiment 1 of the present invention also adopts dual-port SSD: SSD has two data interfaces on the framework, one data interface is used to send and receive data or commands from the host or storage server, and the other data interface is used to connect another SSD. Data is transferred through the port connected to the backup SSD. The difference is that the attributes of the SSD can be set as the main disk or the backup disk.

[0048] The backup process is as follows:

[0049] Step 201, setting the properties of the solid state drive;

[0050] Here, to set the properties of the solid-state hard disk, you can use the button provided by the SSD for the user to choose, for example: a button, pressing it means it is used as a spare disk, and popping it up means it is used as a main disk. The first solid-state hard disk is ...

Embodiment 3

[0056] see image 3 It is a flow chart of the third embodiment of a solid-state hard disk data backup method of the present invention;

[0057] The embodiment of the present invention adopts a single-port SSD: the SSD has only one data port on the framework. When needed, the device of the SSD that needs to be backed up is set as the master disk, and then connected to the backup disk to realize data backup between hard disks. In this embodiment, the two SSDs can be powered by an external power supply.

[0058] The process is as follows:

[0059] Step 301, when the master disk needs backup data, send a connection request;

[0060] When the master disk needs to back up data, the master disk sends a connection request to the backup disk.

[0061] Step 303, after the master disk and the backup disk are connected successfully, the master disk sends the backup data;

[0062] When the backup disk receives the connection request sent by the master disk, it connects with the master di...

Abstract

The invention discloses a data backup method of a solid-state hard disk, which includes: detecting whether a backup disk is successfully connected through a data interface; and sending backup data to the backup disk when the connection is successful. The embodiment of the present invention also provides a corresponding system and a solid-state hard disk. Because the technical solution of the present invention adopts the structure method of SSD with direct backup function, two SSDs are directly connected, data backup becomes simpler, without the help of other devices, data transmission between hard disks is faster, and the backup speed is faster.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to a solid-state hard disk data backup method, system and corresponding solid-state hard disk. Background technique [0002] With the development of storage technology, a solid state disk (SSD, solid state disk) composed of non-volatile flash memory (Flash) chips has appeared; SSD does not use mechanical rotating devices, and has high read and write performance, strong shock resistance, and power supply. With the advantages of low cost, it is widely used in military, vehicle, industrial control, video surveillance, network monitoring, network terminal, electric power, medical, aviation, navigation equipment and other fields. [0003] The performance of SSD determines its application in mid-to-high-end storage services. How to realize efficient and convenient backup, that is, realize direct backup without affecting the current storage service working status and server structure as ...
