Description
Technical Field
The present disclosure relates to the field of data processing technology, and in particular, to the field of block chaining technology. In particular, the present invention relates to the field of data backup technologies, and in particular, to a method, an apparatus, a device, a medium, and a product for processing backup record data based on a block chain.
Background
The automatic backup system is a management tool for data backup, uniformly manages and executes a data backup strategy by adopting a task scheduling system, has the advantages of stability, reliability and comprehensiveness compared with the traditional manual script backup mode, is simple to operate and centrally managed, can quickly and accurately restore data, reduces the operation and maintenance complexity, is very suitable for being used in scenes needing a large amount of data backup management, such as a data center in the financial industry and the like, and can well adapt to the backup management and restoration work of mass data.
In an automated backup scenario, an automated backup system can autonomously perform a particular backup task at a particular time through a pre-customized backup strategy. After each backup task is executed, corresponding data backup record data including backup time, backup type, backup target, backup storage address and the like are generated and used for accurately describing the backup plan. By managing the data backup records, the automatic backup system can intensively manage all backups and retention time in the system, and realize one-key completion of data recovery.
Therefore, backup recorded data is the key for backup management and recovery of the automatic backup system, and mass backup data can be changed into unusable meaningless data due to the loss or tampering of the backup recorded data. Therefore, ensuring that the backup record data is safe, accurate and available is crucial to an automatic backup system.
In an automated backup scenario, the current solution generally uses a traditional database such as MySQL, Oracle, etc. as a system database to perform simple backup or perform master-slave synchronous copy backup. These two solutions present the following safety problems:
risk of data tampering: backup record data in the scene of an automatic backup system is used as historical data, and the data characteristics require that the backup record data cannot be modified and is available all the time. And the traditional database can modify the data, so that the risk of tampering the data after the database is maliciously attacked is increased.
Central structure risk: the centralized structure of the traditional database enables the role of an administrator to have the right to perform all operations, including increasing, deleting, modifying and checking, on the data, and the artificial risk of the administrator for performing wrong operations/maliciously modifying the backup record data is increased.
Single crop of malignancy risk: the traditional database carries out single-point operation on the data nodes to cause the risk of global crash, so that the risk of crash exists in the process of storing backup record data.
Risk of database loss: the traditional database has the risk that a single point of failure of a database server causes data loss.
Therefore, there is a need in the art to provide a safe, accurate and available data management method for backup recorded data.

It should be understood that the number of blockchain nodes and automated backup systems deployed in fig. 1 is merely illustrative. There may be any number of blockchain nodes and automated backup systems, as desired for implementation.
A block chain based backup record data processing method, apparatus, device, medium, and product according to embodiments of the present disclosure will be described in detail with reference to fig. 2 to 10 based on the scenario described in fig. 1.
Fig. 2 schematically shows a flowchart of a method for processing backup record data based on a blockchain according to an embodiment of the present disclosure, which is mainly described from the perspective of a blockchain system.
As shown in fig. 2, the embodiment provides a method for processing backup record data based on a blockchain, where the method is applied to a blockchain system, and the method includes operations S210 to S240, and specifically, the following steps are performed:
in operation S201, a transaction broadcast by an automated backup system is received, where the transaction is generated by the automated backup system based on packing of backup record data, and the backup record data is used to describe a data backup task executed by the automated backup system. Further, the backup record data is used to describe a successful data backup task performed by the automated backup system.
And the automatic backup system triggers a data backup task according to a backup rule in the backup plan. In particular, the data backup task may be triggered once according to a time rule in the backup plan, for example, the automated backup system may trigger the data backup task once according to a certain time period.
After triggering a data backup task, the automated backup system schedules a backup job to execute the data backup task and creates a unique backup task identifier corresponding to the data backup task. And the backup task identifier is a unique identifier uuid which is correspondingly established for the data backup task by the automatic backup system according to the current timestamp.
When a data backup task is executed each time, corresponding backup record data can be generated, the backup record data is used for accurately describing the data backup task, the backup record data comprises information such as a backup object, backup time, a backup type, a backup storage address and backup preservation time of the data backup task, and the backup record data further comprises a unique backup task identifier corresponding to the data backup task.
By generating and managing backup record data, the automatic backup system can intensively manage all data backups in the system and the storage time of the data backups, and the backup data recovery is completed in a key way.
To avoid the bloated block chain system, the present disclosure packs and chains only the backup record data that the data backup task successfully executed.
The present disclosure uses the blockchain system as a way to store backup record data, mainly considering: backup recorded data is used as key data of an automatic backup system, and the artificial interference can be eliminated by matching the design principle of a block chain decentralized structure; backup recorded data is used as log data, the characteristics of no modification and no modification are required, a block chain is matched with a design principle that only the data can be added and cannot be modified, and malicious data tampering is prevented; the full-node redundant backup of the block chain can guarantee the safety of backup record data under extreme conditions.
The blockchain system includes at least three or more private chains. For privacy and security, the blockchain system of the present disclosure needs to build at least more than three private chains for storing backup record data.
In operation S202, a node consensus for the transaction is achieved according to a consensus mechanism in the blockchain system.
The consensus mechanism is a practical Byzantine fault-tolerant (PBFT) consensus algorithm, the backup recorded data are stored by adopting a private chain created by the practical Byzantine fault-tolerant (PBFT) consensus algorithm, the backup recorded data corresponding to a successfully executed data backup task are abstracted into block chain transactions, and after the consensus algorithm achieves consensus at each node of the private chain, the backup recorded data are chained. Based on the PBFT consensus algorithm, the fault-tolerant fault node and the fault-tolerant rogue node (namely the node which intentionally sends error data) are supported, and the reliability of backup record data storage is improved.
In operation S203, the transaction that achieves node consensus is packed into the latest block in the blockchain system and uplinked.
Each block in the block chain system adopts a merkel Tree (Merkle Tree) structure to store the transaction, so that the data can be conveniently searched during data recovery.
In operation S204, storage success information is sent to the automated backup system.
And after receiving the successful storage information, the automatic backup system informs an upper layer application of finishing the data backup task.
After the block chain-based backup record data storage is executed, according to actual needs, recovery of the backup record data is also executed, that is, the block chain-based backup record data processing method provided by the present disclosure further includes a block chain-based backup record data recovery method.
Fig. 3 schematically shows a flowchart of a block chain-based backup record data recovery method according to an embodiment of the present disclosure.
As shown in fig. 3, the embodiment provides a method for restoring backup record data based on a blockchain, where the method is applied to a blockchain system, and the method includes operations S301 to S303, specifically as follows:
in operation S301, a recovery request for the backup record data is received, where the recovery request includes the backup task identifier.
Since the blocks in the blockchain system have redundant backups at each node, any node in the blockchain system can receive a recovery request for the backup record data, and the corresponding backup record data can be searched and obtained from the blocks stored in the nodes according to the backup task identifier.
In operation S302, backup record data is queried in a block stored by a node in the blockchain system according to the backup task identifier.
In operation S303, the queried backup record data is sent to the automated backup system.
By means of the backup record data processing method, storage and recovery of backup record data in an automatic backup scene are achieved, non-falsification data storage and recovery for protecting key data of an automatic backup system are provided, the method can be widely applied to the automatic backup scene, and therefore safe, accurate and available storage and recovery of the backup record data in the automatic backup scene can be guaranteed.
Fig. 4 schematically shows a flowchart of a block chain-based backup record data processing method according to an embodiment of the present disclosure, which is mainly described in the context of an automated backup system.
As shown in fig. 4, the embodiment provides a block chain-based backup record data processing method, which is applied to an automated backup system, and the method includes operation S401 to operation S408, specifically as follows:
in operation S401, a data backup task is triggered according to a backup rule in a backup plan.
The triggering of the data backup task according to the backup rules in the backup plan specifically includes: and triggering a data backup task according to a time rule in the backup plan. For example, an automated backup system may trigger a data backup task once a certain period of time.
In operation S402, a scheduling backup job executes the data backup task, generates and records backup record data describing the data backup task, and creates a unique backup task identifier corresponding to the data backup task.
In operation S402, when the data backup task is executed, the automatic backup system creates a corresponding unique identifier uuid for the data backup task according to the current timestamp.
When a data backup task is executed each time, corresponding backup record data can be generated, the backup record data is used for accurately describing the data backup task, the backup record data comprises information such as a backup object, backup time, a backup type, a backup storage address and backup preservation time of the data backup task, and the backup record data further comprises a unique backup task identifier corresponding to the data backup task.
By managing the backup record data, the automatic backup system can intensively manage all data backups in the system and the storage time of the data backups, and the backup data recovery is completed in one key.
In operation S403, it is determined whether the data backup task is successfully executed, and if the data backup task is successfully executed, operation S404 is performed; if the data backup task is not successfully executed, the backup failure reason is updated, and operation S408 is performed.
In order to avoid the block chain from being too bulky, the present disclosure packs and chains only the backup record data of which the data backup task is successfully executed.
In operation S404, the backup record data corresponding to the successfully executed data backup task is packaged into a transaction of the blockchain system.
In operation S405, the transaction is broadcasted to a blockchain system, such that the blockchain system achieves node consensus for the transaction according to a consensus mechanism in the blockchain system and packages the transaction achieving node consensus into a latest blockchain in the blockchain system and uplinks.
The present disclosure uses the blockchain system as a way to store backup record data, mainly considering: backup recorded data is used as key data of an automatic backup system, and the artificial interference can be eliminated by matching the design principle of a block chain decentralized structure; backup recorded data is used as log data, the characteristics of no modification and no modification are required, a block chain is matched with a design principle that only the data can be added and cannot be modified, and malicious data tampering is prevented; the full-node redundant backup of the block chain can guarantee the safety of backup record data under extreme conditions.
The blockchain system includes at least three or more private chains. For privacy and security, the blockchain system of the present disclosure needs to build at least more than three private chains for storing backup record data.
The consensus mechanism is a practical Byzantine fault-tolerant (PBFT) consensus algorithm, the backup recorded data are stored by adopting a private chain created by the practical Byzantine fault-tolerant (PBFT) consensus algorithm, the backup recorded data corresponding to a successfully executed data backup task are abstracted into block chain transactions, and after the consensus algorithm achieves consensus at each node of the private chain, the backup recorded data are chained. Based on the PBFT consensus algorithm, the fault-tolerant fault node and the fault-tolerant rogue node (namely the node which intentionally sends error data) are supported, and the reliability of backup record data storage is improved.
Each block in the block chain system adopts a merkel Tree (Merkle Tree) structure to store the transaction, so that the data can be conveniently searched during data recovery.
In operation S406, a storage success message sent by the blockchain system is received.
In operation S407, the upper layer application is notified that the data backup task is successful.
In operation S408, the upper layer application is notified that the data backup task fails.
After the block chain-based backup record data storage is executed, according to actual needs, recovery of the backup record data is also executed, that is, the block chain-based backup record data processing method provided by the present disclosure further includes a block chain-based backup record data recovery method.

In operation S502, a restore request for the backup record data is sent to the blockchain system, so that the blockchain system queries the backup record data in the blocks stored by the nodes in the blockchain system according to the backup task identifier, where the restore request includes the backup task identifier.
Since the blocks on the blockchain system have redundant backup at each node, corresponding backup record data can be searched and obtained from the blocks stored by the nodes in the blockchain system according to the backup task identifiers as long as a backup record data recovery request is sent to any node in the blockchain system.
In operation S503, the backup record data sent by the blockchain system is received.
