Description

Technical Field

[0001] The present application relates to the technical field of data storage, and in particular to a data storage method, apparatus, computer equipment, storage medium and program product. Background Art

[0002] With the rapid development of the digital economy, the amount of data has exploded. As an efficient data storage solution, object storage has attracted attention for its high scalability, flexibility and cost-effectiveness. Nowadays, object storage data storage solutions have been widely used in cloud computing, big data, network resource distribution and other fields.

[0003] However, with the development of new infrastructure such as artificial intelligence and industrial Internet, the data generated is growing exponentially. How to effectively manage this data, reduce storage costs, and ensure fast access and security of data has become a pressing problem to be solved.

Users manually select the appropriate storage category for the bucket based on the access frequency and importance of the data.

Some low-frequency data objects may become hot data, and the storage category limits the access experience to the data.

[0067] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0068] With the rapid development of the digital economy, the amount of data has exploded. As an efficient data storage solution, object storage has attracted attention for its high scalability, flexibility and cost-effectiveness. Nowadays, object storage data storage solutions have been widely used in cloud computing, big data, network resource distribution and other fields.

[0069] However, with the development of new infrastructure such as artificial intelligence and industrial Internet, the data generated is growing exponentially. How to effectively manage this data, reduce storage costs, and ensure fast access and security of data has become a pressing problem to be solved.

[0070] In traditional object storage services, users are generally provided with limited storage category options. Users manually select the appropriate storage category for the bucket based on the access frequency and importance of the data. After the user selects the storage category, access to the data is restricted by the storage category. However, as time goes by, the user's access pattern will also change. Some low-frequency data objects may become hot data, and the storage category limits the access experience to the data. At the same time, the access frequency of some data objects may decrease or even tend to be no longer accessed. If users rely on manual adjustment of data object categories, as the amount of data increases, in the case of large amounts of data, it will bring a lot of tedious work to users, and at the same time, data security cannot be guaranteed. It will cause difficulties in the reasonable management of data storage categories, and bring high storage costs to users.

[0071] In view of this, providing a method for realizing automatic classification and storage of data objects is a technical problem that needs to be solved urgently.

[0072] like Figure 1 As shown, in a first aspect of an embodiment of the present application, a data storage method is provided, comprising:

[0073] Step S110: Acquire a user-defined data storage policy of the target server.

[0074] Exemplarily, a user may intuitively input and modify a user-defined data storage policy through a user interface.

[0075] Step S120: Obtain historical access information of the target server.

[0076] Exemplarily, the access activities of all data objects in the storage system of the target server can be monitored and captured, and the historical access information of the target server can be obtained according to the access log by monitoring the access events of the data objects in real time.

[0077] Step S130: extract features from historical access information to obtain feature access information.

[0078] Exemplarily, key features can be extracted from access logs to identify user patterns of the target server, such as the periodicity of access frequency, the distribution of access time, and the changing trend of the size of transmitted data objects, to generate feature analysis reports and provide data input for large model analysis.

[0079] Step S140: Determine the dynamic data storage strategy of the target server according to the characteristic access information.

[0080] For example, the large model can be fine-tuned to adapt it to specific data sets and business needs, so that it can understand and predict data access patterns and output a series of dynamic data storage strategies. These dynamic data storage strategies will be combined with user-defined data storage strategies to form a comprehensive strategy to provide decision-making basis for the intelligent decision engine.

[0081] Step S150: Determine the target data storage policy of the target server according to the user-defined data storage policy and the dynamic data storage policy.

[0082] Exemplarily, the target data storage strategy can be determined by an intelligent decision engine. The intelligent decision engine is responsible for automatically determining the best storage category for the data object to be stored according to the target data storage strategy. The intelligent decision engine uses a complex algorithm to comprehensively consider the access pattern, storage cost, performance requirements and other relevant factors of the data object to determine whether each data object should be stored in standard storage, low-frequency storage or archive storage.

[0083] Step S160: store the data object to be stored in the target server according to the target data storage policy.

[0084] The data storage method, device, computer equipment, storage medium and program product provided by the embodiments of the present application can realize the customization of the data storage policy to a certain extent by obtaining the user-defined data storage policy of the target server, and at the same time, by obtaining the historical access information of the target server and extracting the features of the historical access information, the feature access information is obtained, so as to further generate the dynamic data storage policy of the target server for the data object to be stored according to the feature access information. Therefore, the target data storage policy of the target server can be comprehensively determined by combining the user-defined data storage policy and the dynamic data storage policy, so as to store the data object to be stored in the target server. Therefore, in the ever-increasing amount of user data and the diverse user needs, the automatic classification storage of the data object to be stored can be realized through the dynamic adjustment of the data storage policy, and at the same time, it can ensure that the data storage has a certain customization function, improve the personalization of data storage, thereby reducing the difficulty of data storage, saving the cost of data storage, further reducing the difficulty and cost of managing data objects, improving the access speed of data, and improving the security of data storage.

[0085] In some feasible implementations, the user-defined data storage strategy includes at least one of the data object access frequency, the storage cost budget of the target server, and the data object retention period; the historical access information includes at least one of the accessed data object, the access time, the identity of the accessor, the access request type, and the capacity of the accessed data object; and the target data storage strategy includes at least one of the standard data storage strategy, the low-frequency data storage strategy, and the archived data storage strategy.

[0086] The data storage method, apparatus, computer equipment, storage medium and program product provided in the embodiments of the present application can further enhance the accuracy of automatic classification storage of data objects to be stored and improve the data storage effect by increasing the decision parameters of the data storage strategy, thereby reducing the difficulty of data storage, saving data storage costs, further reducing the management difficulty and management costs of data objects, increasing the speed of data access, and improving the security of data storage.

[0087] In some feasible implementations, obtaining a user-defined data storage policy of the target server includes: collecting a custom data storage policy input by a user; obtaining data storage rules of the target server; and determining the user-defined data storage policy of the target server based on the data storage rules and the custom data storage policy.

[0088] For example, the system administrator can set rules and restrictions for the policy to ensure the rationality and security of the user policy. The policy management module is also responsible for storing the user-defined policy persistently and providing it to other system components, such as the intelligent decision engine, for further processing when needed.

[0089] Exemplarily, the custom data storage policy input by the user can be verified based on the custom policy legal rules and setting restrictions set by the system administrator. When the user enters the custom data storage policy, the custom data storage policy is verified and filtered. If the custom data storage policy fails to pass the verification, an error prompt is given to the user, and the user is required to re-enter the policy. When the custom data storage policy passes the verification, the custom data storage policy is persistently stored to obtain the user-defined data storage policy, and the cached data storage policy is updated. When the dependent component needs to obtain the user-defined data storage policy, the user-defined data storage policy is provided to perform subsequent operations.

[0090] The data storage method provided in the embodiment of the present application can further supervise the user-defined data storage policy to prevent user misoperation from affecting the data storage effect, thereby further improving the security of data storage and the stability and reliability of the target server.

[0091] In some feasible implementations, obtaining historical access information of a target server includes: obtaining a first data object access log of the target server; filtering the first data object access log to obtain a second data object access log; and formatting the second data object access log to obtain historical access information.

[0092] Exemplarily, the user's access operations on each data object in the target server can be monitored and recorded to generate a first data object access log. The first data object access log is cleaned to remove useless and erroneous log records to obtain a second data object access log. The second data object access log is formatted according to a fixed format to obtain historical access information, which is stored so that the historical access information can be used as an original data source and can be directly used for analysis and processing in subsequent processes.

[0093] The data storage method provided in the embodiment of the present application can improve the effectiveness of historical access information and the readability of historical access information by pre-screening and pre-processing the first data object access log of the target server, thereby reducing the difficulty of data storage, saving data storage costs, and further reducing the management difficulty and management costs of data objects.

[0094] In some feasible implementations, data objects to be stored in a target server are stored according to a target data storage strategy, including: obtaining storage information of the data objects to be stored, wherein the storage information includes at least one of an access mode, storage cost, and storage performance requirement; determining a target storage mode corresponding to the data objects to be stored according to the storage information; and storing the data objects to be stored in the target server according to the target storage mode.

[0095] For example, the access mode, storage cost, performance requirements and other related factors of the data object to be stored can be comprehensively considered according to the input target data storage strategy to analyze the storage requirements of the data object to be stored. It is determined whether the data object to be stored is suitable for standard storage, low-frequency storage and archive storage, and the target storage mode of the data object is given.

[0096] The data storage method provided in the embodiment of the present application can improve the automatic classification storage quality of the data object to be stored by determining the target storage mode corresponding to the data object to be stored through the storage information of the data object to be stored, thereby further reducing the difficulty of data storage, saving data storage costs, and further reducing the management difficulty and management costs of data objects.

[0097] In some feasible implementations, the data storage method also includes: obtaining the current storage mode of the data object to be stored; judging whether data migration can be currently performed on the data object to be stored based on the storage status information of the target server; and updating the storage status of the data object to be stored based on the target storage mode if data migration can currently be performed on the data object to be stored.

[0098] Exemplarily, a migration instruction for the data object to be stored can be generated and issued according to the decided target storage mode. Among them, by analyzing the migration instruction, it is determined whether the data object to be stored meets the migration conditions. If the migration conditions are not met, wait for the next evaluation time to re-evaluate, otherwise, execute the subsequent steps. When the data object to be stored meets the data migration conditions, the data object to be stored is migrated from the current object storage category in the current storage mode to the best object storage category given by the target storage mode according to the requirements of the migration instruction. During the migration process, attention is paid to the state of the migration, and specific processing is performed on abnormal situations in the migration process. When the migration of the data object to be stored is completed, the metadata of the relevant object is updated to ensure that the metadata correctly reflects the storage state and storage category of the data object to be stored. Ensure the consistency and integrity of the data.

[0099] The data storage method provided in the embodiment of the present application can further ensure the migration quality of the data objects to be stored by evaluating the migration conditions before data migration is required, and avoid the loss of the data objects to be stored during the migration process, thereby further reducing the management difficulty and cost of the data objects, improving the data access speed, and improving the security of data storage.
