Description

Technical Field

[0001] The present invention relates to the technical field of network storage, and in particular to a network storage integrated snapshot service method, device, equipment and medium. Background Art

[0002] With the rapid development of information technology, emerging technology fields such as big data processing and cloud computing services are rising, which has promoted a profound change in the way data is stored. In this technical context, distributed storage architecture is widely favored due to its high efficiency and scalability, and has become the mainstream choice in the field of data storage. In a distributed file storage system, data is organized, stored, and accessed in the form of files, providing users with flexible and convenient data management capabilities.

[0003] In order to further improve the efficiency and reliability of data management, the snapshot function has gradually become an indispensable part of distributed file storage systems. Snapshots can capture the state of the storage system at a specific point in time, allowing users to go back to that state when needed, thereby effectively dealing with risks such as data loss, damage or misoperation. However, due to the differences in snapshot implementation methods and subtle differences in functions of different file systems, it is challenging for NAS (Network Attached Storage) systems to directly use the snapshot function of the backend file system.

[0004] Traditionally, if a NAS system wants to use the snapshot function of the backend file system, it needs to carry out special docking development for each backend file system, such as developing a client to mount the snapshot volume, or building a web interface to implement snapshot management. This process is not only huge in workload, but also has poor versatility and is difficult to adapt to the ever-changing and expanding storage environment. Therefore, a universal NAS snapshot function docking solution is urgently needed to simplify the integration process with the backend file system snapshot function and improve the availability and flexibility of the NAS system snapshot function.

[0063] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0064] Snapshot service is a data protection technology that can capture the complete data state on a server or storage device at a specific point in time and save it to form a "snapshot" copy. This snapshot can help quickly restore to the state when the snapshot was created in the event of a system failure or data loss, thereby ensuring data integrity and business continuity. Snapshot services usually have agentless features. Some snapshot services, such as Alibaba Cloud Snapshot Service, use an agentless approach, without the need to install additional software on the target server; incremental snapshots: After creating the first full snapshot, subsequent snapshots usually only back up data blocks that have changed since the last snapshot, thereby saving storage space and improving backup efficiency; regular backup: The automatic snapshot function can be used to regularly back up data and retain it for a certain period of time to meet data recovery and compliance requirements. Snapshots can be used in related technical fields such as data recovery, development and test environment construction, and custom image production.

[0065] NAS (Network Attached Storage) is a network device dedicated to data storage. It is connected to computers or other devices through the network to provide file sharing and data storage services. NAS usually has the characteristics of centralized data management, cross-platform file sharing, plug-and-play, and has the advantages of low cost, high efficiency, high scalability and high security.

[0066] One of the core concepts of the embodiment of the present invention is to use parameterized permission control and the file handle of the network storage to realize the snapshot service integration without writing additional interfaces.

[0067] Reference Figure 1 , shows a flow chart of the steps of an embodiment 1 of the XX method of the present invention, which may specifically include the following steps:

[0068] Step 101, sending preset snapshot parameters to a network storage server, so that the storage server determines a permission set according to the snapshot parameters;

[0069] The client sends a series of preset snapshot parameters to the NAS server, which are used by the server to identify and verify the user's permissions and determine the specific parameters of subsequent snapshot operations.

[0070] In one example, the snapshot parameters may be P = {p1, p2, p3, ..., p n}, p n Indicates a parameter, and n indicates the parameter number. One parameter is the access key, and other parameters may be snapshot names, snapshot descriptions, associated files or directories, etc. The definition of parameters may be adjusted according to business needs, and the embodiment of the present invention does not limit this.

[0071] After receiving the parameters, the server first parses the access key and generates a permission set based on the key. This permission set clearly defines the types of snapshot operations that the client can perform, including creating snapshots, deleting snapshots, reading snapshot lists, and reading snapshot file contents. In particular, the delete snapshot permission only allows the deletion of specific snapshot records, but does not allow the deletion of files or contents under the snapshot, nor does it allow the modification of file contents under the snapshot. All files and directories under the snapshot are read-only.

[0072] Step 102, obtaining a snapshot operation type; the snapshot operation type includes creating a snapshot, deleting a snapshot, and viewing a snapshot;

[0073] Determine the specific snapshot operation type that the user wants to perform. Operation types include creating a snapshot, deleting a snapshot, and viewing a snapshot, which means reading a snapshot list or snapshot file contents;

[0074] Step 103, determining the data to be operated according to the snapshot operation type;

[0075] Depending on the snapshot operation type selected by the user, the client needs to specify which data will be the target of the operation.

[0076] In one example, if the user chooses to create a snapshot, the data to be operated is the file or directory for which the user wants to create a snapshot; if the user chooses to delete the snapshot, the data to be operated is the snapshot ID that the user wants to delete.

[0077] Step 104, generating a snapshot request corresponding to the snapshot operation type according to the snapshot operation type and the data to be operated;

[0078] The client constructs a specific snapshot request based on the previously determined operation type and the data to be operated, so as to send it to the NAS server for execution.

[0079] In one example, the request includes the operation type, a unique identifier of the data to be operated such as a file path, a snapshot ID, and possible other parameters such as a snapshot name, a description, etc. This request is the basis for subsequent server-side operations.

[0080] Step 105, determining a file handle according to the snapshot request; the file handle is used to identify and access data;

[0081] To perform a snapshot operation, the client needs to generate a file handle (NFH), which is a unique identifier for subsequent access and operation of data.

[0082] In one example, the file handle is generated by a specific encoding and decoding technology, which includes snapshot information of the file, such as inode ID, snapshot ID, and private data. This information is encoded into NFH for use in subsequent operations.

[0083] A file handle is a data structure used in the operating system to access files; a file handle is a unique identifier used by the operating system for processes to identify and access files. When a file is opened, the operating system creates a handle for the file and returns it to the program for operations such as reading and writing, and controlling the file pointer. The file handle allows programs to operate files through a simple identifier without knowing the actual location of the file in the storage system or other detailed information. It hides the complexity of file operations and provides effective management of file resources. In most operating systems, a file handle is usually represented as an integer or pointer. This value or pointer is maintained internally by the operating system to identify the open file. The file handle usually contains all the necessary information related to the file, such as the physical location on the disk, permission information, current read and write position, etc. This information is crucial for the operating system to perform file operations.

[0084] Step 106, sending the file handle to the network storage server, so that the network storage server completes the corresponding operation and generates an operation receipt;

[0085] The client sends the generated NFH to the NAS server so that the server can decode and obtain the snapshot information and then perform the requested snapshot operation. After receiving the NFH, the server first decodes the snapshot information and then performs the corresponding snapshot operation based on the information, such as creating, deleting or reading the snapshot and generating the corresponding operation receipt.

[0086] Step 107: receiving the operation receipt sent by the network storage server, and completing the snapshot operation according to the operation receipt.

[0087] The client receives the result returned by the server after performing the operation to understand whether the operation was successful and any errors that may have occurred.

[0088] In one embodiment, the operation receipt includes: a success receipt and an error receipt, and step 108 includes the following sub-steps:

[0089] Sub-step S11, when the operation receipt is a success receipt, receiving the success receipt sent by the network storage server, and completing the snapshot operation according to the operation receipt;

[0090] If the operation receipt is a success receipt, it means that the server has successfully executed the requested snapshot operation. The client can update the local status or display a success message to the user based on the information in the receipt.

[0091] Sub-step S12: when the operation receipt is an error receipt, an error message is output to the user, and the snapshot operation is terminated.

[0092] If the operation receipt is an error receipt, it means that the server encountered an error when performing the operation. The client needs to parse the error information in the receipt and display the corresponding error message to the user.

[0093] The success receipt indicates that the server has successfully executed the client's request. The client can use this to confirm the success of the operation and perform subsequent processing, and provide timely feedback on the operation results to improve user experience and satisfaction.

[0094] When the operation receipt is an error receipt, an error message is output to the user, and the snapshot operation is terminated. The error receipt provides the reason for the operation failure, and the client can perform error processing based on it, such as retrying, prompting the user to check parameters, etc. When the operation fails, the operation is terminated in time to avoid unnecessary waste of resources and time.

[0095] By sending preset snapshot parameters to the network storage server and determining the permission set based on these parameters, fine control of snapshot operations is achieved, ensuring data security and compliance. By obtaining the snapshot operation type and determining the data to be operated according to the operation type, different snapshot management requirements can be flexibly responded to. Furthermore, a corresponding snapshot request is generated according to the snapshot operation type and the data to be operated, and the data is identified and accessed through the file handle, which simplifies the complexity of data operations and improves the efficiency of snapshot operations. After sending the file handle to the network storage server, the server can quickly complete the corresponding operation and generate an operation receipt, realizing instant feedback and status tracking of the snapshot operation. In addition, the embodiment of the present invention also has a high degree of versatility and scalability. It designs a universal NAS snapshot function docking mechanism that can easily adapt to the snapshot functions of different back-end file systems without the need for special docking development for each file system. This not only greatly reduces the workload, but also improves the versatility and ease of use of the snapshot function, so that the NAS system can more efficiently utilize the snapshot capabilities of the back-end file system and provide users with more stable and reliable data management services.

[0096] Reference Figure 2 , shows a flow chart of the steps of Embodiment 2 of a network storage integrated snapshot service method of the present invention, which may specifically include the following steps:

[0097] Step 201, receiving preset snapshot parameters sent by a network storage client;

[0098] The server first receives the preset snapshot parameters from the client. These parameters usually include access keys, user IDs, session IDs, or other information used for identity authentication and permission checks. After receiving them, the server will parse the received parameters and prepare for subsequent identity authentication and permission checks.

[0099] In one example, the snapshot parameters may be P = {p1, p2, p3, ..., p n}, p n Indicates a parameter, and n indicates the parameter number. One parameter is the access key, and other parameters may be snapshot names, snapshot descriptions, associated files or directories, etc. The definition of parameters may be adjusted according to business needs, and the embodiment of the present invention does not limit this.

[0100] Step 202, determining a permission set according to the preset snapshot parameters; the permission set is used to determine whether the sender of the preset snapshot parameters has snapshot operation permissions;

[0101] The server generates a permission set based on the received preset snapshot parameters, especially the access key. This permission set defines the types of snapshot operations that the client can perform, such as creating snapshots, deleting snapshots, reading snapshot lists, reading snapshot file contents, etc. In particular, the delete snapshot permission only allows the deletion of specific snapshot records, but does not allow the modification or deletion of file contents under the snapshot.

[0102] In one example, the server may determine the permission set of the client according to the access key by querying an internal permission database or an access control list.

[0103] Step 203, receiving a file handle sent by the network storage client;

[0104] The server receives the file handle generated by the client after determining the type of snapshot operation to be performed and the data to be operated; after receiving the file handle, the server parses the file handle and prepares for subsequent snapshot operations.

[0105] Step 204, determining the snapshot operation type and the data to be operated according to the file handle;

[0106] The server determines the type of snapshot operation that the client wants to perform and the data to be operated based on the parsed file handle.

[0107] Step 205, completing the corresponding operation and generating an operation receipt according to the snapshot operation type, the data to be operated and the permission set;

[0108] The server performs the corresponding snapshot operation according to the determined operation type, data to be operated and permission set, and generates an operation receipt.

[0109] In one example, the process may be that the server first checks the permission set to ensure that the client has the permission to perform the operation. If the client has the permission, the server performs the corresponding snapshot operation (such as creating a snapshot, deleting a snapshot, etc.). After the operation is completed, the server generates an operation receipt, which includes the operation result and related information.

[0110] Step 206, sending the operation receipt to the network storage client, so that the network storage client completes the snapshot operation according to the operation receipt;

[0111] The server sends the operation receipt to the client so that the client can understand the operation result based on the receipt and complete the snapshot operation.

[0112] In one embodiment, the operation receipt includes: a success receipt and an error receipt, and step 206 includes the following sub-steps:

[0113] Sub-step S21, when there is no permission corresponding to the snapshot operation type in the permission set, rejecting the snapshot operation and generating an error receipt;

[0114] If there is no permission corresponding to the snapshot operation type in the permission set, the server rejects the snapshot operation and generates an error receipt to send to the client. The error receipt contains an error code and error information so that the client can understand the reason for the rejection.

[0115] Sub-step S22: When there is a permission corresponding to the snapshot operation type in the permission set, the snapshot operation is performed and a success receipt is generated.

[0116] If there is a permission corresponding to the snapshot operation type in the permission set, the server performs the snapshot operation and generates a success receipt to send to the client. The success receipt usually contains confirmation information and related data of the successful operation. By rejecting unauthorized operations, the server effectively prevents illegal access and abuse of permissions. The error receipt can provide the client with clear error information to help the client understand the reason for the rejection and make corresponding adjustments. In the case of legal permissions, the server will perform the snapshot operation to ensure that the client's needs are met. The success receipt can provide the client with confirmation information of the successful operation, so that the client can be sure that the operation has been successfully completed.

[0117] By sending preset snapshot parameters to the network storage server and determining the permission set based on these parameters, fine control of snapshot operations is achieved, ensuring data security and compliance. By obtaining the snapshot operation type and determining the data to be operated according to the operation type, different snapshot management requirements can be flexibly responded to. Furthermore, a corresponding snapshot request is generated according to the snapshot operation type and the data to be operated, and the data is identified and accessed through the file handle, which simplifies the complexity of data operations and improves the efficiency of snapshot operations. After sending the file handle to the network storage server, the server can quickly complete the corresponding operation and generate an operation receipt, realizing instant feedback and status tracking of the snapshot operation. In addition, the embodiment of the present invention also has a high degree of versatility and scalability. It designs a universal NAS snapshot function docking mechanism that can easily adapt to the snapshot functions of different back-end file systems without the need for special docking development for each file system. This not only greatly reduces the workload, but also improves the versatility and ease of use of the snapshot function, so that the NAS system can more efficiently utilize the snapshot capabilities of the back-end file system and provide users with more stable and reliable data management services.

[0118] Reference Figure 3 , showing a functional architecture diagram of an embodiment of a network storage integrated snapshot service method of the present invention;

[0119] When the NAS client starts the snapshot function, it first sends a request to the NAS server, indicating its intention to perform a snapshot operation on the stored data. After receiving this request, the NAS server will perform a series of checks and processing.

[0120] First, the server checks whether a file has been specified for the first open;

[0121] If it is the first time to open the specified file, the system may obtain the information carried in the snapshot request, parse the directory items in the information, and generate a NFH based on the directory items to store the key information in the NAS server; if it is not the first time to open the file, check whether there is information indicating the snapshot in the NFH. If so, the snapshot information is processed and forwarded to the NAS server. The server determines whether the initiator of this operation has sufficient authority to operate. If so, the snapshot operation is performed normally; if not, an error is returned to the NAS client that initiated this operation;

[0122] If the NAS client initiates a snapshot request operation, the NAS server will execute the process of forwarding this request to the back-end file system; first, it decodes the NFH information to determine the snapshot operation type and the data to be processed, and further determines whether the initiator of this request has the corresponding snapshot processing authority. If so, the decoded information and request will be forwarded to the back-end file system for corresponding snapshot processing. If there is no corresponding authority, an error will be returned to the NAS client.

[0123] Reference Figure 4 , showing a data structure diagram of an embodiment of a network storage integrated snapshot service method of the present invention;

[0124] In this embodiment, when a user initiates a file operation instruction through the NAS client, if it is the first time to open the file, the NAS server will generate a network file handle (NFH). This NFH is generated by encoding inoid, snapshot and private data. In this way, every time a user accesses a file, the system can quickly obtain the file's inode information, the information of the snapshot to which it belongs, and any additional specific information by parsing the NFH, thereby achieving correct access and management of the file;

[0125] Among them, inoid is the abbreviation of "inode ID", which represents the unique identifier of inode. In the file system, inode is a structure that stores file metadata; snapshot is the abbreviation of "snapshot ID", which represents the unique identifier of snapshot; in the file system, a snapshot is a complete copy of the file system at a certain moment; private data refers to additional information related to a specific file or snapshot, which is not covered by the common metadata of the file system (such as inode information). This mechanism improves the efficiency of file access while ensuring the flexibility and scalability of the file system.

[0126] Reference Figure 5 , showing a schematic diagram of data encoding and decoding of an embodiment of a network storage integrated snapshot service method of the present invention;

[0127] In this embodiment, NFH is used as a form of encoding, which includes file information and snapshot information inoid, snapshot, and private data of the file. The decoding process is the inverse operation of this encoding, which converts NFH back to the original snapshot information. This encoding and decoding technology can be a custom encoding technology based on business requirements, a bit operation combined with hash verification, and other technologies.

Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
