Description

Technical Field

[0001] The present invention relates to a cloud storage portable device, in particular to a multi-platform high-availability data cloud storage portable device with a USB interface, belonging to the technical field of computer and server data storage backup. Background Art

[0002] The hard disk is one of the most important storage devices in a computer. Most of the software required for the normal operation of the computer is stored on the hard disk. The existing mainstream hard disks are mainly divided into mechanical hard disks and solid-state hard disks. Mechanical hard disks are traditional hard disk types that use rotating disks and mechanical read / write heads to read and write data. Solid-state hard disks use flash memory chips to store data and have no mechanical moving parts. Solid-state hard disks have faster reading and writing speeds, are more stable, and are more durable than mechanical hard disks. Existing mechanical hard disks or solid-state hard disks do not have network reading functions, and data is directly stored on magnetic disks or flash memory chips. The so-called network disk application is only a specific program residing in the computer, which requires software installation and maintenance, and is not convenient for people to use. Cloud platform cloud storage provides user access in the form of API function interfaces, which are designed for developers to call and integrate. It is inconvenient for ordinary users to use cloud storage directly. At the same time, the massive scale and complexity of public cloud computing cloud storage platforms make it difficult for the availability and reliability of the overall system to achieve the expected goals.

[0003] Existing hard disks (mechanical or solid-state) or USB flash drives do not have network functions, and data is stored on magnetic disks or flash memory chips; the so-called network disk application is currently a specific program that resides in the computer, which requires software installation and maintenance and has no entity. Existing cloud platform cloud storage provides user access in the form of an API function interface, which is designed for developers to call and integrate, and it is inconvenient for ordinary users to use cloud storage directly. The large-scale and complex nature of public cloud computing cloud storage platforms makes it difficult for the availability and reliability of the overall system to meet the expected goals. Well-known large cloud computing companies in the industry also have major downtime, network disconnection, data loss, service suspension and other failure events with widespread impact. How to avoid such events, reduce business and data losses and reduce risks is the technical solution that this patent considers implementing. In this context, the present application proposes a multi-platform, high-availability data cloud storage portable device with a USB interface. Summary of the invention

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment 1

[0031] like Figure 1 to Figure 2 As shown, a multi-platform high-availability data cloud storage portable device with a USB interface includes a USB network disk, the USB network disk includes a network disk housing 1, a lithium battery 2 and a control mainboard 3, and the lithium battery 2 and the control mainboard 3 are both fixedly installed in the network disk housing 1;

[0032] The control mainboard 3 is integrated with a storage module, a processor 33, a WIFI module 34 and a USB module 35. The storage module, the processor 33 and the WIFI module 34 are arranged in sequence on the control mainboard 3. The USB module 35 is located on one side of the WIFI module 34. The interface end of the USB module 35 is provided on one side of the shell of the network disk housing 1. One end of the USB cable can be inserted into the interface end of the USB module 35, and the other end of the USB cable is connected to the host, so that the cloud storage portable device can be provided with data read and write access functions through the storage module; the WIFI module 34 accesses the data storage space of the external storage server or cloud storage through the Internet, so that the computer terminal can access the network cloud storage space in the form of a general U disk interface operation, and complete data backup, archiving and extraction and other services;

[0033] A micro embedded computer system runs inside the control mainboard 3, and the system software run by the control mainboard 3 includes a cloud storage module and a U disk interface module. The cloud storage module is the functional part of cloud computing related to data cloud storage, archiving, and backup. The U disk interface module can receive USB protocol transmission instructions and data sent by the computer, parse the instruction content, convert the address space to the data space corresponding to the cloud storage, connect to the cloud storage module, and return the read and write access results.

[0034] Furthermore, the USB network disk can also adopt a passive wireless USB network disk without battery, wireless WiFi network, and USB2.0 interface;

[0035] The USB network disk can also use a wired USB network disk with Gigabit Ethernet and USB3.0 interface;

[0036] This enables the cloud storage portable device to adapt to different application scenarios and different performance requirements.

[0037] It should be noted that the initial configuration of the USB network disk includes:

[0038] The storage space of the USB network disk is divided into two parts: the TF card flash memory configuration area on the disk (calibrated 100MB) and the cloud area (maximum 64TB).

[0039] When the computer boots the mobile network disk, it accesses the configuration space in the disk. The network disk responds to the computer's IDENTIFYDEVICE instruction (ATA / ATAPI protocol instruction) and returns the parameter confirmation information of the configuration space in the disk, so that the computer host can read and write files in the configuration space. The entries in the configuration file include the mobile network disk's startup password, wifi information, cloud storage platform name, bucket domain name and AK access key, and storage capacity.

[0040] Users can choose to configure the number of cloud storage platforms. If you want to use multiple cloud platforms, you only need to fill in the configuration items (name, domain name, AK key, capacity) of each platform storage bucket in the configuration file, and the network disk will automatically adapt to the corresponding reliability strategy.

[0041] When you start the mobile network hard disk for the first time, after the user saves the configuration items to the configuration area in the disk, the network disk will link the user's cloud storage space, i.e. the cloud area, generate new parameter confirmation information (including basic information such as cloud storage space capacity and addressing range), refresh the host-side hard disk drive letter, present the cloud space to the host in the form of a local hard disk, and respond to the host's IO operations. The computer host can use the cloud storage space just like using a local hard disk.

[0042] That is, the disk configuration area is first provided to the host, and after obtaining the user's configuration data, the cloud area is provided to the host.

[0043] After the initial configuration is completed, the subsequent insertion of the USB to start mounting the network disk will no longer require the setting of the configuration file, and the cloud area entrance will be directly provided.

[0044] About USB network disk password:

[0045] After the mobile network disk is loaded, the host computer will get the drive letter corresponding to the configuration area in the disk. You need to write the opening password into the configuration file and save it. The mobile network disk internal verification password must pass before you can switch to the cloud area. Protect the data security of the mobile network disk.

[0046] The mobile network disk password is set during the mobile network disk initialization phase and can be changed later

The bottom shell body of the network disk shell 1 adopts a plastic structure, and the upper cover plate of the network disk shell 1 is a metal cover for easy heat dissipation.

[0050] The storage module includes a TF mobile storage card 31 and a memory module 32. The TF mobile storage card 31 is calibrated to 100MB so that the cloud storage portable device is compatible with the storage function of an ordinary USB flash drive without the need for additional driver software.

[0051] A power module 4 is also installed in the network disk housing 1. The power module 4 is electrically connected to the lithium battery 2 so that after the USB cable is unplugged, the lithium battery 2 can continue to power the network disk through the power module 4 to achieve safe shutdown and ensure that data is not lost. When using the cloud storage portable device, the power module 4 can be turned on to charge the lithium battery 2 while transmitting data via the USB cable.

[0052] The cloud storage module integrates the SDKAPI of the cloud storage platform. By calling the interface, basic operations such as creation, reading, writing, and deletion of data in the cloud storage space bucket can be implemented. Users are required to provide the access key, domain name, and capacity of their cloud storage space bucket.
