Background
The data backup mode mainly comprises a cold backup mode, a warm backup mode and a hot backup mode. Currently, the mainstream data backup of the network operation and maintenance center is generally based on a remote data replication technology of an intelligent storage system, which is implemented by the intelligent storage system itself to remotely replicate and synchronize data, that is, the intelligent storage system replicates and executes an Input/Output (I/O) operation request of a storage to a remote storage system, and when a disaster occurs, switches to a disaster server to recover the data as soon as possible and as much as possible. In practical application, because the requirements on service continuity and real-time performance are high, the data backup of the service network of an operator can adopt a hot backup or mixed backup mode to backup and store the data.
Traditional data backup relies on backup data storage devices in various places, a disaster recovery mode of two places and three centers is generally adopted, and an operation and maintenance center conducts centralized control. The mode of high in the clouds storage, its main flow includes: 1. establishing a disaster backup center and a disaster backup service storage system, enabling a backup server and a backup program to be in an online state, and setting a data storage mode, a position and a period; 2. transmitting the service data from the main server to a backup system in real time, keeping the synchronization of the backup system and the data of the current application system, and simultaneously backing up and storing the data according to a set mode; 3. when the main server cannot run due to a disaster phenomenon, the backup system can quickly replace the data of the main server to run without supplementing or only needing to supplement less data, so that the business is restored, and the continuity of the business is ensured; 4. for backup data deployed to the cloud, the data is copied during backup, then the data is migrated to the cloud for backup storage, and similarly, when a disaster occurs, the data is quickly recovered from the cloud.

The present invention will be described in further detail with reference to the accompanying drawings and examples.
Referring to fig. 1, an embodiment of the present invention provides a method for disaster recovery backup management of network operation and maintenance data based on a block chain technology, including the following steps:
s1: and determining a plurality of network servers as disaster recovery nodes. In the embodiment of the invention, when the disaster recovery node is determined, the network server with centralized distribution position can be selected as the disaster recovery node.
S2: and connecting the disaster backup nodes and the production nodes to form a consensus network, deploying the block chain program on the disaster backup nodes, forming a block chain network by the plurality of disaster backup nodes, and generating database operation logs by the production nodes. The database operation logs generated by the production node comprise a high-level database operation log and a low-level database operation log.
In the embodiment of the present invention, the production node is a hardware device that executes a specific task, and during the operation process, a log related to the operation of the production node is generated, where the log is a database operation log, and for example, when the production node sends data a from a to b, a database operation log is generated during the process of sending data.
In the embodiment of the present invention, before connecting the disaster recovery node and the production node to form the consensus network, the method further includes: determining the range of the database operation logs needing to be backed up, determining the backup period of the database operation logs, and setting a data grade classification instruction in the production node, wherein the data grade classification instruction is used for classifying the grade of the database operation logs generated by the production node. In the actual operation process of the production node, each operation of the production node generates a database operation log, and many generated database operation logs are irrelevant and do not need to be stored, so the database operation logs generated by the production node are screened by determining the range of the database operation logs needing to be backed up, the database operation logs needing to be backed up are screened out so as to carry out subsequent operation, and the situation that the irrelevant database operation logs are backed up to occupy a server space is avoided.
For the screened database operation logs, whether the generated database operation logs needing to be backed up have primary and secondary scores according to task execution categories of production nodes is further ensured, and in order to further ensure the security of core data, a data grade classification instruction is used for classifying the grades of the database operation logs generated by the production nodes so as to distinguish the core data needing to be backed up from non-core data.
S3: based on the block chain technology, high-level database operation logs generated by production nodes are converted into codes through a Hash algorithm, and then the codes obtained through conversion are uploaded to a block chain network to form transactions.

In the invention, the Hash calculation is carried out on the database operation log, and the obtained code is stored in the block chain, so that the code encryption mode can not be broken by other people except data management personnel, thereby effectively increasing the safety and reliability of data storage.
By using multiple disaster recovery centers to backup data simultaneously and ensuring that high-level database operation logs of each disaster recovery center are determined and written into the blockchain network simultaneously, consistency of data among multiple copies is maintained. Further, a plurality of private chains may be set for a nationwide network, and an association may be set between the private chains.
S4: and when the backup data is restored, retrieving the transaction corresponding to the high-level database operation log on the blockchain network, converting the transaction into the database operation log and restoring the database operation log to the local database where the production node is located.
In the embodiment of the invention, the high-level database operation log generated by the production node is converted into the code through the Hash algorithm, and then the converted code is uploaded to the block chain network to form the transaction.

The invention can realize effective and safe data backup, can quickly recover data when a disaster occurs, and does not need to independently set a centralized data backup center. The main functions are as follows: 1. because the building investment cost of the block chain technology in a single node is low, too large space and equipment are not needed, the remote data backup can be easily realized by the characteristic of distributed storage, the investment of equipment and a site of a disaster backup center is reduced, and the personnel cost and the management cost brought by centralized management are reduced. Meanwhile, the distributed data backup mode also avoids the possibility that all data are destroyed once centralized data management is attacked. 2. The database operation logs are coded by the Hash algorithm and then stored and backed up, only a manager can crack the codes, and other people cannot crack the codes, so that the possibility that the server is attacked by hackers to steal the data is effectively reduced. 3. The multi-node backup mode of the blockchain network effectively realizes multi-node backup, and no matter which network node has a fault or service interruption, the transaction code corresponding to corresponding data can be quickly retrieved on the blockchain and converted into a server operation log, so that services can be quickly recovered.
The invention is based on the number of network nodes involved in the network architecture, the size of the data quantity to be backed up by the database, and the importance degree of the network data of the associated service, and simultaneously considers the regionality, the speed and the capacity of network data transmission and the convenience of management, thereby carrying out reasonable setting. For example, the node configuration number of a certain place is designed according to the number of cities, network node data and a connection mode, wherein the node configuration number is few in nodes, easy to communicate and fast in backup. Because of the hash algorithm technology related to the block chain, the hash algorithm can encode data with any length into a fixed length, so the storage capacity can be reduced, but because the hash algorithm also needs certain resources and storage investment, the data is classified according to safety and importance levels when the data is backed up initially, the block chain storage is carried out in a mode of carrying out the hash algorithm on the data with higher level according to a preset data level classification process, and the data with lower level is stored in the existing mode, so the optimal cost ratio can be reached. Because this encoding technique is irreversible, only the personnel set up can convert the code into the database raw data.
