[0098] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the technical solution of the present application, rather than all of the embodiments. Based on the embodiments recorded in the application documents, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the technical solution of the present application.

[0099] The following is an introduction to some concepts involved in the embodiments of the present application.

[0100] Cloud server: It has a physical network connection with the cloud terminal, is responsible for creating the parent virtual disk and the first-level virtual disk, and provides an operating environment for installing application software on the first-level virtual disk.

[0101] Cloud terminal: It is an x86 or ARM (a type of processor) architecture system, installs and runs the Linux system desktop, and installs and runs the client on the Linux system. It can run TCI / IDV cloud desktops of Windows, Linux, and domestic series systems (such as Zhongbiao Kylin, Galaxy Kylin, Ubuntu Kylin, unified operating system UOS, etc.).

[0102] Cloud desktop: A computer desktop in the form of Windows, Linux, or a domestic series of systems that is presented to cloud terminal users. It runs on cloud terminals and provides an operating environment for application software on the cloud desktop.

[0103] Parent virtual disk file: refers to a clean Windows, Linux, or domestic series virtual disk file that does not have any third-party application software installed, which can be referred to as the parent virtual disk.

[0104] Child virtual disk file: refers to the virtual disk file used to install third-party application software, which can be referred to as a child virtual disk.

[0105] Application software: a third-party application running on the TCI / IDV cloud desktop. In the embodiment of the present application, application software mainly refers to the application that the user needs to use on the cloud desktop.

[0106] Client: also known as user end, refers to the program that corresponds to the server and provides local services to customers. Except for some applications that only run locally (i.e. application software), they are generally installed on ordinary client computers and need to cooperate with the server to run. After the development of the Internet, the more commonly used user terminals include web browsers used for the World Wide Web, email clients for sending and receiving emails, and client software for instant messaging. For this type of application, there needs to be corresponding servers and service programs in the network to provide corresponding services, such as database services, email services, etc. In this way, a specific communication connection needs to be established between the client and the server to ensure the normal operation of the application. The client is essentially also a kind of application software. In the embodiment of the present application, the client refers to the cloud desktop client, which is an application that runs locally on the cloud terminal device to provide cloud desktop services.

[0107] Cloud technology is a general term for network technology, information technology, integration technology, management platform technology, application technology, etc. based on the cloud computing business model. It can form a resource pool, which can be used on demand and is flexible and convenient. Cloud computing technology will become an important support. The backend services of the technical network system require a large amount of computing and storage resources, such as video websites, picture websites and more portal websites. With the rapid development and application of the Internet industry, in the future, each item may have its own identification mark, which needs to be transmitted to the backend system for logical processing. Data of different levels will be processed separately. All kinds of industry data need strong system backing support, which can only be achieved through cloud computing.

[0108] The following is a brief introduction to the design concept of the embodiment of the present application:

[0109] With the development of cloud computing and virtualization technology, cloud desktop has gradually become one of the application options for computer desktops, and its application in various industries is increasingly popular. Cloud desktop is also called virtual desktop or virtual machine. Cloud desktop has a cloud terminal and cloud server architecture. In this architecture, the cloud desktop runs on the cloud terminal side (user side) in the form of a virtual disk; the cloud server is generally composed of one or more high-performance computers, providing virtual disk management and cloud desktop operation and maintenance services for users and terminals.

[0110] The cloud desktop involved in this application is a cloud desktop based on TCI / IDV architecture technology. TCI / IDV cloud desktop refers to a cloud terminal that is virtualized into a logical computer that can be easily managed on a cloud server by using virtualized disk technology (referred to as virtual disk file or virtual disk). Each logical computer desktop is called a cloud desktop. Among them, the cloud terminal can also be a personal computer (Personal Computer, PC), including but not limited to desktops, notebooks, multimedia all-in-one computers, all-in-one computers with screens, etc.

[0111] The operating system (including mainstream Microsoft Windows system, Linux system, and domestic series system) and application software required by users can be deployed on the cloud desktop. Under the TCI / IDV architecture, the cloud desktop is carried and managed in the form of files in virtual disk format. A virtual disk is composed of multiple virtual disk files, such as a parent virtual disk, a primary virtual disk, a secondary virtual disk, etc., among which the primary virtual disk, the secondary virtual disk, etc. are referred to as differential virtual disks. Through the cloud terminal TCI / IDV boot technology, the virtual disk file issued by the cloud server is started on the cloud terminal side, and the entire cloud desktop is presented to the user on the cloud terminal.

[0112] TCI / IDV cloud desktop architecture Figure 1 As shown, the virtual disk file system is created on the cloud server and then sent to the cloud terminal through the network. The cloud terminal starts the TCI / IDV cloud desktop through the TCI / IDV boot technology and displays the computer cloud desktop for users to use, such as the Windows 7 desktop.

[0113] However, as TCI / IDV cloud desktops are increasingly used in various industries, the problem of insufficient disk space on cloud terminals has gradually emerged when users use cloud desktops. The problem of insufficient disk space is because TCI / IDV cloud desktops are implemented through virtual disks and their differential technology.

[0114] Under this technical architecture, compared with the desktop usage of ordinary PCs, there is still a gap in the cloud terminal disk space utilization of TCI / IDV cloud desktops compared with ordinary PCs.

[0115] Taking the disk space required by TCI / IDV cloud desktop running in virtual disk file format as an example, the maximum space required is twice the maximum upper limit of the parent virtual disk. This is mainly because TCI / IDV cloud desktop is composed of parent virtual disk + child virtual disk (which can include multiple children, such as primary virtual disk..., secondary virtual disk...), which is composed of two parts. Figure 2 As shown, the child virtual disk is used to realize the personality and restore functions of the cloud desktop, and the maximum size of the child virtual disk is equal to the size of the parent virtual disk, so it requires twice the space.

[0116] For example, for a 50GB TCI / IDV cloud desktop, the maximum upper limit of the parent virtual disk is 50GB, and the maximum upper limit of the child virtual disk is also 50GB, then 100GB of physical disk space is required. If there is insufficient space, the cloud desktop will display a blue screen. On an ordinary PC, a 50GB desktop occupies 50GB of physical disk space.

[0117] In the related art, the problem of insufficient disk space of cloud terminals is mainly solved by expanding the disk capacity, but this solution is costly and limits the application of cloud desktops.

[0118] In view of this, the embodiments of the present application provide a disk space management method, device, electronic device and storage medium. Since the embodiments of the present application create at least one parent virtual disk file and at least one first-level virtual disk file, group each application software according to a preset classification rule, obtain at least one application software package, and install at least one application software package to different first-level virtual disk files respectively, further, send at least one parent virtual disk file and their corresponding first-level virtual disk file name sets to a cloud terminal, so that the same first-level virtual disk files of multiple operating systems can use one parent virtual disk file, effectively saving physical disk space, and the object can select the first-level virtual disk file to be downloaded according to demand, and after receiving the disk download request for the target first-level virtual disk file sent by the cloud terminal, send the target first-level virtual disk file to the cloud terminal, so that only the first-level virtual disk file selected by the object needs to be sent to the cloud terminal, which can make full use of the physical disk space of the cloud terminal, improve the disk space utilization rate, and thus alleviate the problem of insufficient storage space.

[0119] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

The application scenario diagram includes two terminal devices 310 and a server 320, wherein the terminal device 310 is a cloud terminal in the embodiment of the present application, and the server 320 is a cloud server.

[0121] In the embodiment of the present application, a client related to the cloud desktop may be installed on the terminal device 310, and the client may be software (such as a browser, cloud desktop software, etc.), or a web page, a small program, etc. The server 320 is a background server corresponding to the software or web page, small program, etc., or a server specifically used to provide a cloud desktop, which is not specifically limited in the present application.

For example, when the method is executed by the server 320 and the terminal device 310 together, the server 320 creates at least one parent virtual disk file and at least one primary virtual disk file, groups each application software according to a preset classification rule, obtains at least one application software package, and installs at least one application software package to different primary virtual disk files, then sends at least one parent virtual disk file and a corresponding primary virtual disk file name set to the terminal device 310, and after receiving a disk download request for a target primary virtual disk file sent by the terminal device 310, sends the target primary virtual disk file to the terminal device 310, so that the terminal device 310 starts the corresponding cloud desktop on the terminal device 310 based on the target primary virtual disk file and the corresponding parent virtual disk file.

[0123] In an optional implementation, the terminal device 310 and the server 320 may communicate with each other via a communication network.

[0124] In an optional implementation, the communication network is a wired network or a wireless network.

[0125] It should be noted that Figure 3 The figure is only an example. In fact, the number of terminal devices and servers is not limited and is not specifically limited in the embodiments of the present application.

[0126] In an embodiment of the present application, when there are multiple servers, the multiple servers can form a blockchain, and the servers are nodes on the blockchain; as in the disk space management method disclosed in the embodiment of the present application, the virtual disk files involved can be saved on the blockchain.

[0127] In addition, the embodiments of the present application can be applied to various scenarios, including not only cloud technology scenarios, but also including but not limited to artificial intelligence, smart transportation, assisted driving and other scenarios.

Taking the execution subject as a cloud server as an example, the specific implementation process of the method includes the following steps S41-S43:

[0130] S41: The cloud server creates at least one parent virtual disk file and at least one primary virtual disk file;

[0131] Among them, different parent virtual disk files correspond to different operating system types. For example, the operating system corresponding to the parent virtual disk file 1 is Windows 10, and the operating system corresponding to the parent virtual disk file 2 is Linux.

[0132] For the management and operation architecture of cloud desktops, depending on the business needs of the user scenario, a cloud terminal may need to run two different types of systems, such as Windows 10 and Ubuntu. Therefore, the cloud server supports the creation of parent virtual disk files for multiple operating systems. For cloud desktops that need to use multiple different operating system types on the same cloud terminal, the process of creating virtual disk files by the cloud server is as follows:

[0133] For Cloud Desktop 1, Ubuntu system:

[0134] Create Ubuntu parent virtual disk file 1 of cloud desktop 1;

[0135] Create Ubuntu primary virtual disk file 1 of cloud desktop 1;

[0136] For Cloud Desktop 2, Windows 10 system:

[0137] Create Win10 parent virtual disk file 2 of cloud desktop 2;

[0138] Create Win10 level 1 virtual disk file 2 of cloud desktop 2;

[0139] For Cloud Desktop 3, Windows 10 system:

[0140] There is no need to create the parent virtual disk file 3 of cloud desktop 3. Directly use the Win10 parent virtual disk file 2 of cloud desktop 2.

[0141] Create Win10 level 1 virtual disk file 3 of cloud desktop 3.

[0142] Compared with the related art, the method of creating a parent virtual disk file and a first-level virtual disk file for each cloud desktop will result in wasteful occupation of storage space on the cloud server and cloud terminal side. In this application, the first-level virtual disk file with the same operating system only needs to use one parent virtual disk file, which effectively saves physical disk space.

[0143] S42: The cloud server groups the application software according to a preset classification rule to obtain at least one application software package, and installs the at least one application software package to different primary virtual disk files respectively;

[0144] Specifically, the cloud server can set different classification rules according to the needs of users. For example, in the cloud classroom scenario, application software can be grouped according to subjects to obtain application software package 1 used in art classes, which can include various painting and color matching software, and application software package 2 used in music classes, which can include various music players and instrument simulation software. The application software packages are installed into different primary virtual disk files, and users can select the primary virtual disk files they need to download according to their needs.

[0145]

[0146] Among them, the parent disk is the parent virtual disk file, and the first-level difference is the first-level virtual disk file. As can be seen from Table 1, in this application, when there are three types of users in the user scenario and three different combinations of software need to be used: according to different user scenarios, multiple application software are installed separately or in combination in different first-level differences according to actual needs. This can avoid all software being installed on the same first-level difference, resulting in a single difference space occupying a large space in the cloud terminal. As shown in the table above, create a Win10 parent disk, and then install software 1, 2, and 3 on different first-level differences according to user scenarios, which require 11.5GB, 11GB, and 12.5GB of space respectively. In the related art, all three software are installed in a first-level difference, create a Win10 parent disk, and then install software 1, 2, and 3 on the first-level difference, which requires 13.5GB of space. For example, when user 1 uses the cloud desktop, in this application, the first-level difference of software package 1 with software 1 installed is sent to the cloud terminal, occupying 11.5GB of cloud terminal space. In the related art, although user 1 only needs to use software 1, because the application software is not classified and packaged into different first-level differences, the first-level differences of three softwares installed at the same time need to be sent to the cloud terminal, occupying 13.5GB of cloud terminal space. Therefore, the solution in this application can effectively save the disk space of the cloud terminal.

[0147] Application software is classified and packaged into different software packages. Compared with the method of installing all software in a virtual disk in related technologies, this avoids the problem of insufficient space in the cloud terminal and maximizes the smoothness of using the cloud desktop. Because application software is installed and used together in the smallest combination, it avoids software occupying too many system resources, causing driver conflicts and background processes grabbing system resources and causing jams.

[0148] It should be noted that the parent virtual disk and the first-level virtual disk are both stored in the form of files on the physical disk of the cloud terminal, so they can be called parent virtual disk files and first-level virtual disk files. Users choose to enter different cloud desktops according to their needs, that is, to run different first-level virtual disk files.

[0149] S43: The cloud server sends at least one parent virtual disk file and a set of corresponding first-level virtual disk file names to the cloud terminal, and after receiving a disk download request for a target first-level virtual disk file sent by the cloud terminal, sends the target first-level virtual disk file to the cloud terminal, so that the cloud terminal starts the corresponding cloud desktop on the cloud terminal based on the target first-level virtual disk file and the corresponding parent virtual disk file.

[0150] Among them, since the operating system types corresponding to the first-level virtual disk files in the same first-level virtual disk file name set are the same, the first-level virtual disk file name set only needs to display the available first-level virtual disk file names corresponding to the parent virtual disk file. After the user selects the first-level virtual disk file to be downloaded, the cloud server sends the first-level virtual disk file selected by the user to the cloud terminal.

[0151] In an embodiment of the present application, by creating at least one parent virtual disk file and at least one first-level virtual disk file, each application software is grouped according to a preset classification rule, at least one application software package is obtained, and at least one application software package is installed to different first-level virtual disk files respectively. Further, at least one parent virtual disk file and a corresponding first-level virtual disk file name set are sent to the cloud terminal. In this manner, for a parent virtual disk file, its corresponding first-level virtual disk file name set indicates that a parent virtual disk file may correspond to multiple first-level virtual disk files, that is, when there are multiple first-level virtual disk files with the same operating system, only one parent virtual disk file needs to be sent, which effectively saves physical disk space, and the object can select the first-level virtual disk file to be downloaded according to demand. After receiving the disk download request for the target first-level virtual disk file sent by the cloud terminal, the target first-level virtual disk file is sent to the cloud terminal. Therefore, only the first-level virtual disk file selected by the object needs to be sent to the cloud terminal, which can make full use of the physical disk space of the cloud terminal, improve the disk space utilization rate, and thus alleviate the problem of insufficient storage space.

[0152] In an optional implementation, step S43 may be specifically implemented as follows:

[0153] First, the disk space information of the cloud terminal in the disk download request is obtained. When it is determined that the disk space information meets the disk delivery conditions, the target first-level virtual disk file is sent to the cloud terminal.

[0154] Specifically, when the cloud terminal sends a target first-level virtual disk download request to the cloud server, it can also report the disk space information of the cloud terminal, so that the cloud server can send the target first-level virtual disk file after determining that the disk delivery conditions are met.

[0155] In an optional implementation, the cloud server sends a disk space collection instruction to the cloud terminal, so that the cloud terminal monitors and uploads real-time and historical data of space resource consumption of the cloud terminal physical disk.

[0156] Since the underlying system of the cloud terminal uses the Linux system, the space resource collection instructions of the Linux system can be used for collection. The collection method is real-time acquisition. The collection can be initiated by the client running on the cloud terminal, and the disk space information is recorded locally on the cloud terminal. The disk space information includes: the overall space resources of the cloud terminal, the currently occupied resources, and the available free resources. The client sends the disk space information to the cloud server. The collected space resource information is used to calculate the remaining available resources of the cloud terminal in order to determine the execution strategy of actions such as software package distribution and deletion.

[0157] In an optional implementation, the disk space information includes remaining space resource information, and whether the disk space information meets the disk delivery condition is determined in the following manner:

[0158] Based on the remaining space resource information, it is determined that the remaining space resource of the cloud terminal is not less than the running space occupied by the target first-level virtual disk file, and the disk space information meets the disk delivery conditions;

[0159] Based on the remaining space resource information, it is determined that the remaining space resource of the cloud terminal is less than the running space occupied by the target first-level virtual disk file, and the disk space information does not meet the disk delivery conditions.

[0160] Specifically, if the remaining space resources of the cloud terminal are not less than the operating space occupied by the target first-level virtual disk file, the target first-level virtual disk can be issued to the cloud terminal, that is, the disk issuance condition is met. If the remaining space resources of the cloud terminal are less than the operating space occupied by the target first-level virtual disk file, it indicates that the cloud terminal cannot provide the space required to run the target first-level virtual disk file, that is, the disk issuance condition is not met.

[0161] In an optional implementation, the running space occupied by the target first-level virtual disk file includes: the space occupied by the target first-level virtual disk file, and the space occupied by the second-level virtual disk file corresponding to the target first-level virtual disk file.

[0162] The secondary virtual disk file is used to record the operation process data of the cloud desktop. Specifically, when determining whether to send the primary virtual disk file to the cloud terminal, it is necessary to determine whether the cloud terminal has enough storage space to store the primary virtual disk file and the secondary virtual disk file.

[0163] In an optional implementation, the disk space information includes at least one of the historical occupied space of at least one secondary virtual disk file and the occupied space of a parent virtual disk file corresponding to the target primary virtual disk file. The occupied space of the secondary virtual disk file can be determined based on the following two methods:

[0164] Method 1: using an average value of the historical occupied space of at least one secondary virtual disk file as the occupied space of the secondary virtual disk file, wherein the historical occupied space of the secondary virtual disk file is recorded after the cloud terminal closes the cloud desktop in response to a closing operation of the object;

[0165] Method 2: Determine the occupied space of the secondary virtual disk file based on the occupied space of the parent virtual disk file corresponding to the target primary virtual disk file of a preset ratio.

[0166] Specifically, since the secondary virtual disk file records the operation process data of the cloud desktop, the size cannot be accurately calculated before the cloud desktop runs. When the cloud terminal has run the primary virtual disk file corresponding to the secondary virtual disk file, the cloud terminal will record the occupied space of the secondary virtual disk file as its historical occupied space, and report the historical occupied space information to the cloud server. The cloud server can use the average value of the historical occupied space as the occupied space of the secondary virtual disk file; when the cloud terminal has not run the primary virtual disk file corresponding to the secondary virtual disk file, that is, there is no historical occupied space information, then the preset ratio of the occupied space of the parent virtual disk file corresponding to the primary virtual disk file is used as the occupied space of the secondary virtual disk file. For example, the preset ratio can be 0.5, then 0.5 times the occupied space of the parent virtual disk file is used as the occupied space of the secondary virtual disk file. In specific implementation, the preset ratio can be customized as needed, and this application does not make specific restrictions here.

[0167] In the embodiment of the present application, when the cloud desktop runs a large set of application software, there are problems such as insufficient space and blue screen, and when there are many application software installed in the cloud desktop or a lot of file data stored, the cloud desktop can run without any problems, achieving the same experience as running on a normal PC. The disk space of the cloud terminal can be fully utilized without the need to expand the additional physical hard disk space.

[0168] In an optional implementation, the disk space information includes occupied space resource information; when it is determined that the disk space information does not meet the disk delivery condition, step S43 further includes:

[0169] Based on the occupied space resource information, the occupied space of the deletable resources of the cloud terminal is determined. If it is determined that the deletable resources will be deleted and the disk space information meets the disk delivery conditions, the resource deletion instruction and the target first-level virtual disk file are sent to the cloud terminal so that the cloud terminal can delete the deletable resources according to the resource deletion instruction.

[0170] Specifically, when it is determined that the disk space information does not meet the disk delivery conditions, the deletable resources in the cloud terminal can be searched according to the occupied space resource information. If it is determined that after deleting the deletable resources, the remaining space of the cloud terminal can store the operating space occupied by the target first-level virtual disk, the target first-level virtual disk file can still be delivered. It should be noted that the cloud server can send a resource deletion instruction and a target first-level virtual disk file to the cloud terminal at the same time, or it can first send a resource deletion instruction to the cloud terminal, and then send the target first-level virtual disk file after the cloud terminal deletes the deletable resources. This application does not make specific limitations here.

[0171] In addition, the cloud server sends a resource deletion instruction to the cloud terminal, instructing the cloud terminal to delete some or all of the deletable resources, as long as the disk space information meets the disk delivery conditions after deletion. For example, the deletable resources include: first-level virtual disk file 1, first-level virtual disk file 2, and first-level virtual disk file 3, then the cloud server can instruct the cloud terminal to delete first-level virtual disk file 1 and first-level virtual disk file 2 through the resource deletion instruction.

[0172] In an optional implementation, if after it is determined that the deletable resources are to be deleted, the disk space information still does not meet the disk delivery conditions, or the cloud terminal does not have deletable resources, a prompt message is sent to the cloud terminal so that the cloud terminal prompts the object that it cannot enter the cloud desktop according to the prompt message.

[0173] Specifically, if the space occupied by the deletable resources is smaller than the space occupied by the target primary virtual disk file, or there are no deletable resources, the target primary virtual disk file cannot be delivered, and the user is prompted that he cannot enter the cloud desktop.

[0174] In the embodiment of the present application, the object refers to a user who uses a cloud desktop on a cloud terminal. This article mainly uses the user as an example for explanation.

[0175] For a cloud terminal with a physical disk of 128GB, in the scenario of using three software packages on the Win10 system, the physical disk space resource data record details (i.e. disk space information) are shown in the following table:

[0176]

[0177] Among them, the first-level difference of the software package refers to the first-level virtual disk file in which the software package is installed, the restored second-level difference of the software package refers to the need to delete this second-level virtual disk file after the cloud desktop is closed to clear the data generated during the user's use of the cloud desktop, and the personalized second-level difference of the software package refers to the need to retain this second-level virtual disk file after the cloud desktop is closed to retain the data generated during the user's use of the cloud desktop.

[0178] In the embodiment of the present application, a scheduling algorithm is used to analyze the historical space data of various types of application software packages occupying the cloud terminal, determine the type of application software package requested by the user, and automatically schedule the application software package to run in the optimal way, thereby maximizing the use of the space resources of the local system of the cloud terminal, improving the operating efficiency of the application software, and achieving maximum use of the disk space of the cloud terminal under the background of virtual disk technology.

[0179] See also Figure 5 , which is a schematic diagram of the composition structure of a TCI / IDV cloud desktop system in an embodiment of the present application, including at least a cloud terminal side and a cloud server side. The cloud terminal side includes: a cloud terminal, a cloud desktop, and a client.

[0180] The cloud server side includes: cloud server, parent virtual disk file, primary virtual disk file, application software (hereinafter referred to as software), virtual disk dispatch center (hereinafter referred to as dispatch center). The functions of the client and dispatch center are as follows:

[0181] Client:

[0182] (1) The client runs on the Linux system of the cloud terminal and is used to connect to the cloud server and report the space information of the cloud terminal;

[0183] (2) The client receives the virtual disk file (including the parent virtual disk file and the first-level virtual disk differential file) issued by the virtual disk scheduling center;

[0184] (3) The client stores the virtual disk file sent by the virtual disk dispatch center to the directory specified by the cloud terminal;

[0185] (4) The client receives the disk space collection instruction issued by the virtual disk scheduling center;

[0186] (5) The client monitors and uploads the real-time and historical data of the physical disk space consumption of the cloud terminal to the virtual disk scheduling center according to the "disk space collection instruction";

[0187] (7) The client generates a secondary virtual disk file based on the parent virtual disk file and the primary virtual disk file according to the operation instructions of the cloud terminal user (the user clicks on the client interface to enter a certain cloud desktop), and boots and starts the specified cloud desktop directly on the cloud terminal through the secondary virtual disk file.

[0188] Virtual Disk Scheduling Center:

[0189] (1) The virtual disk scheduling center runs on the cloud server;

[0190] (2) The virtual disk dispatch center sends instructions to the client to collect cloud terminal disk space;

[0191] (3) The virtual disk dispatch center receives the real-time and historical data of the physical disk space consumption resources of the cloud terminal reported;

[0192] (4) The virtual disk scheduling center classifies the application software and installs it into different primary virtual disk files;

[0193] (5) The virtual disk scheduling center calculates and analyzes the optimal scheduling strategy based on the operations of the cloud server administrator and the space resource consumption of the cloud terminal physical disk, and sends the parent virtual disk file and the first-level virtual disk file to the client.

[0194] In the specific implementation, the dispatch center sends the parent virtual disk file (for example, Win10 system) to the client, the client receives the parent virtual disk file and stores it in the cloud terminal. If there are multiple parent virtual disk files, multiple parent virtual disk files are sent to the client. If multiple software packages use the parent virtual disk file of the same system type, then only one parent virtual disk file needs to be sent to the cloud terminal. However, the traditional practice is that multiple software packages send multiple parent virtual disk files to the client.

[0195] Since a parent disk can be used as a dependency for the primary virtual disk files of multiple software packages, the list of available software packages corresponding to the parent disk (i.e. the set of primary virtual disk file names) needs to be synchronized to the client so that users can access the cloud desktop corresponding to the software package and open the software package. Figure 6 As shown, a list of software package 1, software package 2, and software package 3 is sent to the client, and the user can enter the cloud desktop by clicking the corresponding software package.

[0196] In the embodiment of the present application, in order to solve the problem of insufficient storage space in the cloud terminal, the storage capacity of the local disk space resources of the cloud terminal is fully utilized through differential technology to optimize the scheduling and allocation of resources.

[0197] It should be noted that the virtual disk scheduling center involved in this application can also be extended to the field of using virtual disk technology on the cloud server side to start the cloud desktop as a virtual server desktop. For example, when the cloud server is used as a time-sharing multiplexing environment, that is, it is only used as a certain type of cloud server at the same time, the method in this application can also be used. For example, when building a test environment for a cloud server, different test environments need to be switched at different times. Through the parent virtual disk technology, as well as the first-level difference and the second-level difference, the required test environment can be effectively switched without wasting the space of the cloud server.

[0198] Another disk space management method in the present application is introduced below. Taking the execution subject as a cloud terminal as an example, the specific implementation process of the method includes the following steps S71-S73:

[0199] S71: The cloud terminal receives at least one parent virtual disk file and the corresponding first-level virtual disk file name set sent by the cloud server, and displays each first-level virtual disk file name set to the object;

[0200] Different parent virtual disk files correspond to different operating system types, and different primary virtual disk files are installed with different application software packages;

[0201] S72: The cloud terminal sends a disk download request for the target first-level virtual disk file to the cloud server in response to the object's selection operation for the target first-level virtual disk file;

[0202] S73: The cloud terminal receives the target first-level virtual disk file sent by the cloud server, and starts the corresponding cloud desktop on the cloud terminal based on the target first-level virtual disk file and the corresponding parent virtual disk file.

[0203] In an optional implementation, the cloud terminal sends a disk download request including disk space information of the cloud terminal to the cloud server.

[0204] The target primary virtual disk file is sent by the cloud server when the disk space information determines that the disk space information meets the disk delivery conditions.

[0205] In an optional implementation, step S73 is implemented in the following manner:

[0206] First, a secondary virtual disk file of the target primary virtual disk file is generated, and then, based on the secondary virtual disk file, the target primary virtual disk file and the corresponding parent virtual disk file, the corresponding cloud desktop is started on the cloud terminal.

[0207] The secondary virtual disk file is used to record the operation process data of the cloud desktop. After the user selects the primary virtual disk file to be downloaded, the client generates a secondary virtual disk file based on the parent virtual disk file and the primary virtual disk file, and boots the specified cloud desktop directly on the cloud terminal through the secondary virtual disk file.

[0208] In an optional implementation, step S73 further includes the following contents:

[0209] Receive resource deletion instructions sent by the cloud server, and delete deletable resources based on the resource deletion instructions.

[0210] The resource deletion instruction is sent by the cloud server after it determines to delete the deletable resources and the disk space information meets the disk delivery conditions. The cloud terminal deletes the specified resources according to the resource deletion instruction to provide sufficient storage space for the operation of the target first-level virtual disk file.

[0211] In an optional implementation, step S73 further includes:

[0212] Receive a prompt message sent by the cloud server, and according to the prompt message, the object cannot enter the cloud desktop, wherein the prompt message is sent to the cloud terminal by the cloud server after it is determined to delete the deletable resources, but the disk space information still does not meet the disk delivery conditions, or the cloud terminal does not have the deletable resources.

[0213] In an optional implementation, step S73 further includes:

[0214] In response to a closing operation on the object, the cloud desktop is closed and the historical occupied space of the secondary virtual disk file is recorded and sent to the cloud server, so that after receiving the historical occupied space, the cloud server determines the occupied space of the secondary virtual disk file based on the historical occupied space; and based on the type of the secondary virtual disk file, determines the target operation to be performed on the secondary virtual disk file.

[0215] Specifically, after the user closes the cloud desktop, the occupied space of the secondary virtual disk file is recorded and reported to the cloud server, so that the occupied space of the secondary virtual disk file can be pre-calculated when the cloud desktop corresponding to the secondary virtual disk file is started next time.

[0216] In an optional implementation, based on the type of the secondary virtual disk file, the target operation performed on the secondary virtual disk file includes:

[0217] If the type of the secondary virtual disk file is restore, the secondary virtual disk file is deleted; otherwise, the secondary virtual disk file is retained.

[0218] Specifically, the types of secondary virtual disk files include restore and personalization. If the type is restore, the secondary virtual disk file needs to be deleted after the user closes the cloud desktop. If the type is personalization, the secondary virtual disk file needs to be retained after the user closes the cloud desktop.

[0219] In an embodiment of the present application, by creating at least one parent virtual disk file and at least one first-level virtual disk file, each application software is grouped according to a preset classification rule, so that the first-level virtual disk files with the same multiple operating systems can use one parent virtual disk file, thereby effectively saving physical disk space. Only the first-level virtual disk file selected by the object needs to be sent to the cloud terminal, which can make full use of the physical disk space of the cloud terminal, improve disk space utilization, and thus alleviate the problem of insufficient storage space.

[0220] See also Figure 8 , which is an interactive flow chart of a disk space management method in an embodiment of the present application, used to illustrate the interactive logic in the software package scheduling process, including the following steps:

[0221] S801: The scheduling center sends the parent virtual disk file and software package list;

[0222] S802: The client receives and stores the parent virtual disk file and displays a software package list;

[0223] S803: The client determines whether there is a primary virtual disk file of software package n locally. If so, execute step S812; if not, execute step S804;

[0224] S804: The client reports disk space information and a disk download request;

[0225] S805: The scheduling center receives the disk space information and the disk download request, and prepares a primary virtual disk file of software package n;

[0226] S806: The dispatch center determines whether the remaining space resources of the cloud terminal are sufficient to store the primary virtual disk file and the secondary virtual disk file of the software package n. If so, execute step 807; if not, execute step S808;

[0227] S807: The dispatch center sends the first-level virtual disk file of software package n;

[0228] S808: The dispatch center determines whether the remaining space resources of the cloud terminal are sufficient to store the primary virtual disk file and the secondary virtual disk file of the software package n after deleting the deletable resources. If yes, execute step S809; otherwise, execute step S811;

[0229] S809: The dispatch center sends a resource deletion instruction and the primary virtual disk file of software package n;

[0230] S810: The client deletes the deletable resource and executes step S812;

[0231] S811: The client prompts "Insufficient space, unable to send";

[0232] S812: The client generates a secondary virtual disk file of software package n;

[0233] S813: The client starts the cloud desktop of software package n.

[0234] The following three embodiments are used to introduce the specific implementation of the disk space management method in this application: Embodiment 1, software package 1 scheduling operation process:

[0235] Scheduling process:

[0236] a. The client initiates a request to download the first-level virtual disk file

[0237] (1) When the user clicks to use "Software Package 1" on the client, the client determines that there is no first-level virtual disk file of Software Package 1 locally, and then sends a request to download "the first-level virtual disk file of Software Package 1" to the dispatch center;

[0238] (2) When the user clicks to use "Software Package 1" on the client, the client determines that there is a primary virtual disk file of Software Package 1 locally, and then enters the operation process;

[0239] b. The client reports the cloud terminal space information

[0240] (3) At the same time, the client reports the cloud terminal disk space information to the dispatch center;

[0241] c. The dispatch center issues the first-level virtual disk file

[0242] (4) The dispatch center receives the client's download request and the disk space information of the cloud terminal;

[0243] (5) The dispatch center determines whether the remaining space of the cloud terminal is sufficient to store "the primary virtual disk file of software package 1" + "the restored secondary virtual disk file of software package 1";

[0244] Since there is no historical data for the size B of the restored secondary virtual disk file of software package 1, it is calculated based on the preset ratio of the maximum upper limit space of the parent virtual disk of software package 1.

[0245] (6) If the space is sufficient, the "first-level virtual disk file of software package 1" is issued;

[0246] (7) If the space does not meet the conditions for issuing, determine whether there is data that can be deleted, for example, the primary virtual disk files of other software packages can be deleted, and return a "primary virtual disk file of software package n (n=1, 2, 3, ...) can be deleted" instruction to the client, and the client executes the deletion of the primary virtual disk file of software package n;

[0247] (8) The dispatch center determines again whether the space is sufficient. If it is sufficient, the "first-level virtual disk file of software package 1" is sent. Otherwise, the client is prompted with the message "insufficient space and cannot be sent".

[0248] Operation process:

[0249] a. Client startup software package 1

[0250] (1) At this point, the cloud terminal has the Win10 "parent disk" and "primary virtual disk file of software package 1" that software package 1 depends on to start;

[0251] (2) The client generates a "secondary virtual disk file of software package 1";

[0252] The client starts the cloud desktop 1 of software package 1 from the "secondary virtual disk file of software package 1";

[0253] b. Close the cloud desktop on the client 1

[0254] (1) During the operation of cloud desktop 1, the secondary virtual disk file will continue to grow and occupy space;

[0255] (2) When there is no user using cloud desktop 1, the client closes cloud desktop 1;

[0256] c. Client collects information

[0257] (1) After cloud desktop 1 is closed, the client records the size of the secondary virtual disk file of software package 1;

[0258] (2) Since cloud desktop 1 is a restored desktop, its secondary virtual disk file needs to be deleted after closing, so that the terminal space is released;

[0259] d. Start software package 1 again

[0260] (1) When software package 1 is started again, the "secondary virtual disk file of software package 1" is created again to start cloud desktop 1 of software package 1;

[0261] (2) After closing, the size of the secondary virtual disk file of software package 1 is recorded again, and the secondary virtual disk file is deleted;

[0262] e. Statistical software package 1's secondary virtual disk file size

[0263] When software package 1 is started multiple times, there are multiple secondary virtual disk files of software package 1. Data statistics are performed on them to calculate the average size and record it as A.

[0264] Example 2, software package 2 scheduling operation process:

[0265] Scheduling process:

[0266] a. The client initiates a request to download the first-level virtual disk file

[0267] (1) When the user clicks to use "Software Package 2" on the client, the client determines that there is no primary virtual disk file of Software Package 2 locally, and then sends a request to download "Primary virtual disk file of Software Package 2" to the dispatch center;
