In combination with the server shown in FIG. 2 and the terminal shown in FIG. 4, an embodiment of the present application provides a data backup method. Please refer to FIG. 6. FIG. 6 is a diagram of another data backup method provided by an embodiment of the present application. Schematic. Wherein, as shown in FIG. 6, a data backup method provided by an embodiment of the present application may include:

Step S601: The terminal obtains the backup request of the first user and the identity of the first user.

Specifically, after the user completes the operation on the terminal, the user logs in to the data backup system, and the terminal sends the data that the user needs to back up, the user identity identifier, and the backup request to the server; the backup request is used to request the first user Back up the data to be backed up. The following description is made with reference to FIG. 7, the content of the display interface of the data backup system may be, for example, but not limited to, as shown in FIG. As shown in Figure 7, Figure 7 is a schematic diagram of a data and backup system display interface provided by an embodiment of the present application. The data backup system interface 700 includes: a text box 701 for displaying the data that the user needs to back up. "Represents the data that needs to be backed up; the backup button 702 is used to indicate the user's backup request; the exit button 703 is used to instruct the user to give up the backup data. Further, if the user selects the backup button, the terminal sends the user's backup request to the server.

Step S602: The terminal sends the backup request and the identity identifier to the server.

Step S603: The server obtains the backup request and the identity sent by the terminal.

Step S604: The server determines a backup scheme according to the identity identifier and the backup request.

Optionally, the backup scheme may include: one or more storage systems to be backed up, the number of backups, the primary storage system, the backup storage system, and the backup delay time.

Among them, storage systems include storage systems such as Solid State Disks (SSD) and distributed storage systems. Different users have different backup requirements, and the server stores storage solutions corresponding to different user identities. The backup storage system is determined according to user requirements. For example, user 1’s backup requirements are: user data needs to be backed up to storage system A and storage system B; user 2’s backup requirements are: user data needs to be backed up to storage system A and storage System B and Storage System C.

Specifically, the server stores backup schemes corresponding to different users, which are described below in conjunction with Table 1. The storage content of the data backup system may be, for example, but not limited to, as shown in Table 1:

Table 1

It can be seen from Table 1 that the corresponding backup plan for the user whose user ID is 001 is: backup user data to storage system A and storage system B respectively, and the number of backups is 1 copy respectively, and storage system A is the main storage system, and System B is the backup storage system, and the backup delay time between backup storage systems is 30s; the corresponding backup plan for the user whose user ID is 002 is: backup user data to storage system A, storage system B, and storage system C, respectively The number of each is 1 copy, where storage system A is the primary storage system, storage system B and storage system C are backup storage systems, and the backup delay time between backup storage systems is 30s.

Step S605: The server establishes a connection between the primary storage system and the corresponding backup storage system in the blockchain network according to the backup scheme.

Specifically, the backup scheme includes the storage system that the user needs to back up, and the server establishes a connection with the storage system that the user needs to back up, so as to facilitate subsequent backup of user data to the corresponding storage system. Optionally, the main storage system may be a node in the blockchain network, or the main storage system may not be a node in the blockchain network. The backup storage system is a node in the blockchain network (it can be understood that multiple backup storage systems correspond to multiple nodes in the blockchain network). Based on the characteristics of the blockchain, the backup data is not easily tampered with maliciously.

For example, the user storage solution with the identity identifier 001 is to back up user data to storage system A and storage system B, respectively, so the server establishes a connection with storage system A and storage system B.

Step S606: The server backs up the first data to be backed up to the corresponding backup storage system.

Specifically, the server backs up the data to be backed up to the corresponding backup storage system according to certain backup rules (including backup sequence, etc.). Both the backup storage system and the primary storage system can be nodes in the blockchain network. Developers can preset that the system corresponding to a certain node is the primary storage system, and then the system corresponding to other nodes in the network is the backup storage system. The embodiment of the present application does not limit the specific object content and form corresponding to the backup storage system and the main storage system.

Optionally, before the server backs up the first data to be backed up to the corresponding backup storage system, the method further includes: the server performs desensitization processing on the first data to be backed up. Some sensitive information in the backup data is deformed through desensitization rules to achieve reliable protection of sensitive privacy data. In the case of security data or some commercially sensitive data, without violating system rules, reform the real data and provide test use, such as personal information such as ID card number, mobile phone number, card number, customer number, etc. Data desensitization.

Optionally, before the server backs up the first data to be backed up to the corresponding backup storage system, the method further includes: the server encrypts the first data to be backed up according to a hash algorithm. The encryption system involved in the embodiments of this application is composed of plain text, cipher text, algorithms, and keys. The sender (that is, the server) encrypts the data with an encryption key through an encryption device or encryption algorithm and sends it out. After receiving the ciphertext, the receiver (that is, the storage system, such as the backup storage system) uses the decryption key to decrypt the ciphertext and restore it to plaintext. In the transmission process, even if the ciphertext is stolenly obtained by illegal elements, what is obtained is only the unidentifiable ciphertext, which plays a role of data confidentiality.

Optionally, if the backup scheme of the first user includes a backup storage system, the server backing up the first user data to the one or more storage systems includes:

The server backs up the first user data to the primary storage system at the first time, and backs up the first user data to the backup storage system at the second time, and the first time and the second time The time interval is the backup delay time.

Optionally, if the backup scheme of the first user includes multiple backup storage systems, the server backing up the first user data to the one or more storage systems includes:

The server determines a backup sequence for backing up the first user data to the multiple backup storage systems according to the backup space and remaining space capacity of the storage system occupied by the first user data, and the storage system includes one or more backup spaces ；

The server sequentially backs up the first user data to the multiple backup storage systems according to the backup sequence and the backup delay time.

Specifically, each storage system includes one or more backup spaces, and each backup space has a corresponding remaining space capacity. The server determines the logical address where the user data is backed up to the storage system according to the logical address of the first user data at the terminal, and then determines the corresponding backup space of the first user data in the storage system according to the logical address of the storage system, for example, the backup corresponding to user 002 In the solution, storage system B and storage system C are backup storage systems, the backup space corresponding to the user data backed up to storage system B is backup space 1, and the remaining capacity of backup space 1 is 30G; the first user data is correspondingly backed up to storage The backup space of system C is backup space 1, and the remaining capacity of backup space 2 is 40G.

Optionally, the server sorts the multiple backup storage systems in ascending order of the ratio of the memory size of the backup space occupied by the first user data to the remaining space capacity of the backup space, and the The sequence is determined as the backup sequence of multiple standby storage systems.

Specifically, because storage strategies of storage systems are different, the same user data size after being backed up to different storage systems may be the same or different.

For example, the user data of user 002 is backed up to storage system B backup space 1 and the memory size of backup space 1 is 0.5G, and backed up to storage system C backup space 1 and the memory size of backup space 2 is 0.4G. The ratio of the memory size of the backup space 1 occupied by the user data of the user 002 to the remaining space capacity of the backup space 1 is 1/6, and the ratio of the memory size occupied by the backup space 2 to the remaining space capacity of the backup space 2 is 1. /10, so the backup of storage system B and storage system C is storage system B→storage system C.

In the implementation of the embodiments of the present application, the server backs up user data to one or more storage systems according to the user's backup scheme, avoiding multiple backups of user data to different storage systems, reducing user data backup time, and effectively improving user data backup efficiency.

Please refer to FIG. 8. FIG. 8 is a schematic diagram of still another data backup method provided by an embodiment of the present application. When the server backs up the first user data to the storage system, it may include step S801-step S817; among them, for step S801-step S806, please refer to the corresponding step S601-step S606 respectively in sequence, which will not be repeated here; the following are the steps S807-Step S817 detailed introduction:

Step S801: The terminal obtains the backup request of the first user and the identity of the first user.

Step S802: The terminal sends the backup request and the identity identifier to the server.

Step S803: The server obtains the backup request and the identity sent by the terminal.

Step S804: The server determines a backup scheme according to the identity identifier and the backup request.

Step S805: The server establishes a connection between the primary storage system and the corresponding backup storage system in the blockchain network according to the backup scheme.

Step S806: The server backs up the first data to be backed up to the corresponding backup storage system.

Step S807: The terminal obtains the modification instruction of the first user.

Specifically, after obtaining the user's backup request, the terminal may modify the first user data; the modification instruction is used to instruct the server to modify part or all of the first data to be backed up . For example, take the first user backing up a large number of pictures as an example for description. After the first user sends the backup request, the user may perform modification operations such as deleting one or more photos and adding other photos.

Step S808: The terminal sends the modification instruction to the server.

Step S809: The server obtains the modification instruction.

Step S810: The server obtains the second data to be backed up.

Step S811: The server backs up the second data to be backed up to the corresponding backup storage system.

Specifically, the server backs up the modified data modified by the first user to the storage system but may not back up all the first user data to the storage system.

Optionally, the server backs up part or all of the modified data to one or more storage systems, including:

The server backs up the modified data after the modification operation in the logical address segment of the terminal and the first mapping table according to the partial data or all the data after the modification operation to the address corresponding to the one or more storage systems Block, the first mapping table includes the corresponding relationship between the modified data in the logical address segment of the terminal and the second mapping table, and the second mapping table includes the modified data in the one or more storage systems The corresponding logical address segment and the physical address in the corresponding relationship, the physical address includes a physical block address and/or a combination of a physical block address and a predetermined offset.

Please refer to FIG. 9, which is a logical address mapping diagram provided by an embodiment of the present application. As shown in Figure 9, take the logical address segment mapping relationship between terminal user data and storage system A as an example; user data A (that is, valid data A or Valid A as shown in the figure; user data B, C, and The meaning of the object described by D can refer to the description of user data A, which will not be repeated hereafter). The logical address segments of user data B, user data C and user data D in the terminal are logical address segment 1, logical address segment 2, and logical address respectively. Segment 3 and logical address segment 4. The logical fields corresponding to user data A, B, C, and D in storage system A are logical address segment 1, logical address segment 3, logical address segment 5 and logical address segment 8, storage system A The physical addresses corresponding to the logical address segment 1, logical address segment 3, logical address segment 5, and logical address segment 8 on the storage system A are physical address 1, physical address 2, physical address 3, and physical address 4, respectively. Address 1 and physical address 3 have preset offsets. The server stores the user data of the terminal to the physical address corresponding to the storage system according to the mapping table relationship between the logical address segment of the terminal user data and the logical address segment of the storage system.

When the first user performs a modification operation on user data A, the data A after the modification operation becomes data F, and the server stores the data F in the physical address 1 in the storage system A. If the modified data F occupies a much larger memory than the data A, and the physical address 1 of the storage system A cannot back up part of the data of the data F, part of the data of the data F is backed up to the predetermined offset of the physical address 1.

Step S812: The terminal sends a view instruction of the first user to the first data to be backed up and/or the second data to be backed up.

Specifically, the first user may have one or more backup data in the storage system, and the user inputs the target backup data to be viewed through the terminal.

Step S813: The server obtains the viewing instruction.

Step S814: The server obtains the first data to be backed up and/or the second data to be backed up from the main storage system according to the view instruction and the backup plan of the first user.

Specifically, the server sends the target backup data (that is, the first data to be backed up and/or the second data to be backed up) identification to the primary storage system corresponding to the first user, and the primary storage system determines the target backup through the identification. Data, and then send the target backup data to the server.

Optionally, when the server cannot send the target backup data from the main storage system within a preset time period, the server sends the identifier of the target backup data to the backup storage system, and obtains the target backup data from the backup storage system.

Optionally, if there are multiple backup storage systems in the backup scheme corresponding to the first user, the target backup data is acquired from the backup storage system in the order of backing up the first user data.

Step S815: The server sends the first data to be backed up and/or the second data to be backed up to the terminal.

Step S816: The terminal receives the first data to be backed up and/or the second data to be backed up.

Step S817: The terminal outputs the first data to be backed up and/or the second data to be backed up.
