[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Embodiment 1

[0031] Reference Figure 1-Figure 5 , a remote disaster recovery backup system is built on a building data center platform, including:

[0032] Data center module;

[0033] Data collection module, the data collection module is connected with a remote control module, the remote control module is connected with a data center module, the data center module is connected with a user management module, the data collection module is connected with a data compression module, the data compression module is connected with a data encryption module, the data encryption module is connected with a data transmission module, the data transmission module is connected with a verification module, the data collection module adopts data mirroring technology, and the data encryption module adopts data AES algorithm;

[0034] AES Algorithm:

[0035] The formula of AES encryption algorithm is C=E(K,P), where K is the key, P is the plaintext, and C is the ciphertext;

[0036] The AES encryption algorithm is a symmetric block cipher algorithm that encrypts data in blocks. The size of a block is fixed at 128 bits. The AES encryption process includes grouping the plaintext, each group is 128 bits long, and then encrypting one group at a time until all the plaintext has been encrypted. The number of AES encryption rounds depends on the key length used, specifically:

[0037] 1. When using a 128-bit key, the number of encryption rounds is 10;

[0038] 2. When using a 192-bit key, the number of encryption rounds is 12;

[0039] 3. When using a 256-bit key, the number of encryption rounds is 14;

[0040] The AES algorithm is based on a substitution-permutation network (also known as an SP network), which is different from the Feistel cipher structure in the DES algorithm. Each round of AES operations includes row shift, byte substitution, column mixing, and round key addition. These operations are reversible, making the decryption process the inverse operation of the encryption process. In the decryption process, reverse row shift, reverse byte substitution, round key addition, and reverse column mixing are performed sequentially until the original plaintext is restored.

[0041] Monitoring module, the monitoring module is connected to the alarm module, the alarm module is connected to the network redundancy module, the network redundancy module is connected to the backup device module, the monitoring module is connected to the data collection module, the data compression module, the data encryption module, the data transmission module and the verification module, the network redundancy module adopts multi-line load balancing and intelligent DNS technology to avoid data loss caused by single point failure, and the multi-line load balancing technology adopts a weighted polling algorithm;

[0042] Weighted Round Robin Algorithm:

[0043] Weighted Round Robin (WRR) is a load balancing algorithm that assigns different weights to each server according to the different processing capabilities of the servers so that it can accept service requests with corresponding weights. The weighted round robin algorithm generates a server sequence that contains all servers. The number of occurrences of each server in the sequence is equal to its weight value, and the distribution of servers in the generated sequence should be as uniform as possible. The core idea of ​​the weighted round robin algorithm is to assign weights according to the processing capabilities of the servers. Servers with high weights will process more requests. However, the original weighted round robin algorithm has some problems. For example, servers with large weights may process a large number of requests in a short period of time, resulting in unbalanced load. Therefore, there is an optimized weighted round robin algorithm that selects servers by calculating totalWeight and currentWeight to achieve more uniform load distribution.

[0044] Automatic backup module, the automatic backup module is connected with a switching module and a setting module, the automatic backup module is connected with a data collection module, a data compression module, a data encryption module, a data transmission module and a verification module, the verification module is connected with a distributed storage module, the distributed storage module is connected with a disaster recovery module, the disaster recovery module is connected with a data recovery module, the data recovery module is connected with a test module, the data collection module is used to collect change data in the data center module, the data compression module is used to compress the collected data, the data encryption module is used to encrypt the backup data, the data transmission module is used to transmit the encrypted data to the distributed storage module, the verification module is used to check the integrity of the backup data, the distributed storage module is used to store the backup data on multiple nodes in a dispersed manner, and transmit it to the disaster recovery module for backup, the monitoring module is used to monitor the backup task execution and data transmission status of the backup data in real time, the alarm module is used to detect abnormal status and trigger the alarm in real time, the data recovery module is used to recover the backup data in the disaster recovery module, the test module is used to simulate the backup data process for testing, the distributed storage module adopts a distributed storage algorithm, and the distributed storage algorithm includes hash remainder partitioning and consistent hash algorithm partitioning;

[0045] 1. The formula for hash modulo partitioning is has(key)%N, where N is the total number of machines. The advantage of this partitioning algorithm is that it is simple and direct. You only need to estimate the data and plan the nodes to ensure data support for a period of time. It uses the HASH algorithm to let a fixed part of the requests fall on the same server, so that each server processes a fixed part of the requests, which plays the role of load balancing + divide and conquer;

[0046] 2. The consistent hashing algorithm partitioning is to minimize the changes in the mapping relationship between the client and the server when the number of servers changes. The algorithm builds a consistent hash ring and maps each IP node in the cluster to a certain position on the ring to optimize data distribution and adjust the mapping relationship when the server changes. This algorithm can reduce the significant changes in the mapping relationship caused by changes in the number of servers, thereby improving the stability and availability of the system.

[0047] Reference Figure 2 The user management module includes a registration unit, a login unit and a permission management unit. The registration unit is connected to the login unit, and the login unit is connected to the permission management unit.

[0048] Reference Figure 3 The setting module includes a frequency setting unit, a time setting unit and an execution unit. The frequency setting unit is connected to the time setting unit, and the time setting unit is connected to the execution unit.

[0051] The implementation principle in this embodiment is as follows: when in use, the data collection module collects the change data in the data center module, including the addition, modification and deletion operations, and compresses the collected data to reduce the volume of the backup data, save transmission time and cost, and transmits the compressed backup data to the data encryption module. The data encryption module encrypts the backup data to protect the security of the backup data and prevent data leakage. The compressed backup data is transmitted to the verification module through the data transmission module. The verification module can verify the integrity and recoverability of the backup data, and then the backup data is transmitted to the distributed storage module, and the data is dispersedly stored on multiple nodes. When a node fails, other nodes can take over the data stored therein to ensure the continuous availability of the data. The data is transmitted to the disaster recovery backup module for storage. At the same time, the monitoring module can monitor the backup task execution and data transmission status of the backup data in real time. The alarm module is used to detect abnormal status and trigger an alarm in real time. The network redundancy module realizes redundancy at the network level to ensure the reliability of data transmission and avoid data loss caused by single point failure. Through the settings of the setting module and the switching module, manual operation backup and automatic operation backup switching can be performed. The backup data in the disaster recovery backup module is restored through the data recovery module. The test module can simulate the backup data process for testing to ensure the stability of the system.
