Description

Data storage method, data acquisition method, system, device and medium

Technical Field

The present invention relates to the field of terminal device storage management technologies, and in particular, to a data storage method, a data acquisition method, a system, a device, and a medium.

Background

The mobile phone photographing function is a functional point which is very important and competitive for current mobile phone manufacturers, and the storage, management and application of the corresponding multimedia files are also the most basic functions in current intelligent local storage. However, with the development of media technology, the number of photos and recorded videos is increasing due to the upgrading of the photographing modules of various mobile phone manufacturers, and in addition, the number of media files is increasing due to the appearance of high-pixel photos, special-effect photos, 8K 60-frame videos and the like, so that the occupied storage space is increased, the problem that the storage space of the terminal storage device is often insufficient is caused, and although the storage capacity of the device is continuously increased, the insufficient storage space is still a problem to be faced. The storage space of the terminal storage device may affect the use experience of the terminal user on one hand and may affect the performance and stability of the local storage on the other hand.

In order to solve the problem of insufficient storage of the media data, a user mainly cleans a part of the media data manually according to the actual use requirement, or stores a part of the media data into a mobile storage and a cloud disk to increase the residual space of the equipment. However, the existing processing methods have the following defects:

(1) for the processing mode of clearing data: the user is faced with selection difficulties and is forced to discard a part of the data, so that the user cannot reuse the discarded data; (2) for the processing mode of moving to the mobile storage or the cloud disk storage: part of local storage can browse backed-up or stored files only by opening a cloud disk application; the user cannot visually check the cloud disk storage file in the local media management application, and this phenomenon may cause the user to gradually fade and forget this part of data, for example, part of the terminal does not support the cloud disk album page. The cloud disk storage file is not considered as a real file on a local storage and cannot be identified by the terminal media management service. For example, after uploading a local picture to a cloud disk for storage, although the file can be viewed locally through the cloud disk, the MediaProvider (media storage) of the Android system cannot store the cloud disk picture data. In addition, when the third-party application uses the local terminal media file, the file only stored in the cloud disk cannot be browsed, unless the cloud disk file is downloaded to the local storage again, for example, when the image is shared in the WeChat, the image content in the cloud disk cannot appear, and even if part of the application provides support for the mainstream cloud disk, the part of the application needs to perform additional adaptation work.

s102, constructing reduced file data corresponding to the original file data;

wherein the data volume of the reduced file data is smaller than that of the original file data;

and the metadata information in the original file data is consistent with the metadata information in the corresponding reduced file, so that the one-to-one correspondence between the local reduced file and the original file in the cloud disk is ensured. The metadata information includes multi-dimensional attribute content of the file, and for example, the metadata information includes shooting time information, shooting location information, longitude and latitude of a shooting location, and the like.

Reduced file data can be viewed, moved, copied, modified, etc.; and the reduced file data can be recognized and managed by MediaProvider in the terminal device.

In an implementable scheme, the data type of the original file data is consistent with the data type of the corresponding reduced file data, and the file name of the original file data is consistent with or associated with the file name of the corresponding reduced file data;

s103, uploading original file data to a cloud disk server;

s104, establishing mapping relation information between original file data and corresponding reduced file data in the cloud disk server;

storing the mapping relation information into a local database of the terminal equipment; and/or uploading the mapping relation information to a cloud database of the cloud disk server.

When the mapping relation information is only stored in the terminal equipment or the cloud disk server, the mapping relation information is requested to be acquired from the other side after the communication connection is established between the terminal equipment and the cloud disk server.

And S105, storing the reduced file data in a local storage, and deleting the corresponding original file data.

Specifically, acquiring storage path information of original file data in a local storage;

And storing the reduced file data under the storage path of the deleted original file data, and ensuring the validity and rationality of file data access and management.

In this embodiment, resource data such as media resources is stored in the terminal device in the form of a reduced file, and an original file of the media resources is stored in the cloud disk, so as to provide a mapping management service for the local reduced file and the original file in the cloud disk, where the local reduced file and the original file in the cloud disk both correspond to the physical file.

In addition, the data storage method of the embodiment further includes:

adding attribution information corresponding to the reduced file data in a local database of the terminal equipment;

Example 2

As shown in fig. 2, the data storage method of the present embodiment is a further improvement of embodiment 1, specifically:

step S102 includes:

s10211, acquiring the data type of the original file data;

s10212, establishing a corresponding reduction processing rule according to the data type;

s10213, adopting a reduction processing rule to perform reduction processing on the original file data to obtain corresponding reduced file data.

Specifically, as shown in fig. 3, when the data type corresponds to an image, the reduction processing rule includes a compression resolution process, and the reduced file data includes a thumbnail file of a set resolution;

when the data type corresponds to audio, the reduction processing rule comprises reducing code stream and/or cutting audio duration, and the reduction file data comprises audio files with set code stream and/or set duration (for example, 10 s);

when the data type corresponds to a video, the reduction processing rule comprises at least one of reducing the video resolution, reducing the code stream and cutting to shorten the video time length, and the reduction file data comprises a video file of at least one of setting the video resolution, setting the code stream and setting the video time length (for example, 10 s);

when the data type corresponds to text, the reduction processing rule comprises cutting text content, and the reduced file data comprises a text file with a set word number (for example, 100 bytes); the file data itself occupies a small storage space, and in order to further reduce the volume ratio of such files, a file which only retains 100 bytes of content can be used as a contracted text of the text file.

When the data type corresponds to a preset format file (such as xls, ppt, pdf, etc.), the reduction processing rule includes file replacement, and the reduced file data includes an empty file that is consistent with the file name of the original file data.

Of course, the reduction processing rules of different file types can be reset and adjusted according to actual requirements.

Step S104 includes:

s1041, acquiring first address information of original file data in a cloud disk server;

s1042, obtaining second address information of the reduced file data in a local database;

s1043, establishing a mapping relation between the first address information and the second address information to obtain mapping relation information between the original file data and the corresponding reduced file data.

In an implementation scenario, step S105 is followed by:

adding local version identification information corresponding to each reduced file data in a local database of the terminal equipment; acquiring cloud disk version identification information corresponding to original file data in a cloud disk database of a cloud disk server;

and judging whether the local version identification information is consistent with the cloud disk version identification information, if not, selecting the larger version identification information of the two version identification information as the reference version identification information, and updating the data version of the lower version identification information to the reference version identification information.

In an implementation scenario, step S105 is followed by:

adding local synchronization version information and local latest version information corresponding to each reduced file data in a local storage of the terminal equipment;

when the local synchronization version information is inconsistent with the local latest version information, the local latest version information is sent to the cloud disk server so as to update the version of the corresponding original file data in the cloud disk server to the local latest version information; or the like, or, alternatively,

acquiring cloud disk synchronous version information and cloud disk latest version information corresponding to original file data in a cloud disk database of a cloud disk server;

when the cloud disk synchronization version information is inconsistent with the cloud disk latest version information, the cloud disk latest version information is sent to the terminal equipment so as to update the version of the corresponding reduced file data in the local storage to the cloud disk latest version information; or the like, or, alternatively,

and when the local synchronization version information is inconsistent with the local latest version information and the cloud disk synchronization version information is inconsistent with the cloud disk latest version information, receiving an input control instruction to determine reference version information, and updating the version of the reduced file data in the corresponding local storage or the version of the original file data in the cloud disk server according to the reference version information.

Specifically, the version synchronization rule in the present embodiment is specifically described with reference to fig. 4:

after the contraction part is constructed through the constructor and the original file is uploaded, the local storage of the terminal device and the cloud disk respectively maintain a file, and the two files have a mapping relation with each other. In order to keep the data synchronization between the local and cloud disk, the data synchronization between the local and cloud disk is needed. However, since the local device has a condition of network disconnection, a version data synchronization rule is needed to maintain that the versions on both sides can be correctly synchronized. The version data synchronization rule adds two data fields, a "synchronization version" and a "latest version", to the databases maintained locally and by the cloud disk. Any updates to files on the local or cloud disk will add the "latest version" version number, and the local and cloud disk "latest version" run independently. When data between the local and the cloud disks are synchronized in a network environment, version numbers of the local and the cloud disks in the latest version are compared with respective version numbers of the synchronous version, and if the latest version is equal to the synchronous version, the latest version indicates that a user does not modify the data from the side, and the data on the side does not need to be synchronized to a mapping end. If the "latest version" is higher than the "synchronization version", that is, it indicates that the user has modified data from the side, the data needs to be synchronized to the corresponding mapping end. If only one side of the local and cloud disks is updated, the files can be directly and synchronously updated to the other side. If the files on both sides of the local cloud disk and the cloud disk are updated, the user is required to solve the conflict and determine to select the party to be finally reserved.

The working principle of the data storage method of the present embodiment is specifically described below with reference to fig. 5:

(1) the local terminal equipment of the user stores file data such as common files, multimedia files and the like, all the stored files have a corresponding set of stored recorded data in a local database, the stored recorded data correspond to the local files one by one, and some main attributes and metadata information of the local files are stored. When a user requests to optimize a storage space or upload files, a 'builder' is used for reducing original files such as common files or multimedia files stored in a local storage according to a 'reduction processing rule';

(2) in the contracted piece construction process in the step (1), the 'constructor' can establish a 'mapping rule' of the original piece and the contracted piece through an algorithm in the mapping management service to ensure the one-to-one corresponding relation of the original piece and the contracted piece; the user can acquire the address information of the corresponding original through the mapping management service, and also can acquire the address information of the contracted piece through the original mapping; the mapping management service can provide support for the following function (5);

(3) after (1) generating the original and the contracted piece, the original is uploaded to a cloud disk, the contracted piece is reserved in a local storage of a terminal device, the storage position of the contracted piece is consistent with the original storage position of the original, the file name and the file type are completely the same, and other metadata information in the contracted piece is completely consistent with the original except data information. After the original file is uploaded, the entity file of the original file is not reserved in the local storage of the terminal equipment.

(4) After (1) generating an original and a contracted piece, actively deleting original data information in a local database by a 'constructor' and inserting newly generated contracted piece data information; in addition, a new mark field in the database maintains the attribution information of the data to the original/contracted piece. When a user uses files such as multimedia files or common files, the local media management actively inquires the data information of the currently operated files, and if the currently operated files are contracted pieces, original pieces corresponding to the contracted pieces are obtained by actively calling the mapping management service through the local media management.

(5) The original stored in the cloud disk server and the local contracted piece in the terminal equipment can be synchronized regularly, the cloud disk server and the local media management can add two field information of a synchronous version and a latest version to the data information of each file, the synchronous version is the last synchronous version number of the original and the contracted piece, and the latest version is the version information of the original or the contracted piece after being changed relative to the synchronous version. When the mapping management service synchronizes the cloud disk original and the local contracted part, different version data synchronization works according to the latest versions of the cloud disk original and the local contracted part.

Example 3

The data storage method of the present embodiment is a further improvement of embodiment 2, and specifically:

as shown in fig. 6, step S102 includes:

s10221, obtaining a space storage state parameter of local storage;

s10222, determining the data optimized storage grade of the terminal equipment based on the space storage state parameter;

s10223, constructing reduced file data corresponding to the original file data in the local storage based on the data optimization storage level;

wherein the data optimized storage level is inversely related to the data size of the reduced file data.

In an embodiment, the space storage status parameter includes a total storage capacity and a storage usage amount of the terminal device, and step S10222 includes:

calculating the ratio of the storage usage to the total storage capacity;

generating a data optimized storage grade according to the ratio;

wherein, the size of the ratio is positively correlated with the optimized storage level of the data.

As shown in fig. 7, step S102 includes:

s10231, acquiring the use frequency corresponding to the original file data in the local storage within a set time period;

s10232, determining the data optimization storage grade of the original file data based on the use frequency;

when the use frequency reaches different set thresholds, different data optimization storage grades are triggered, and the data optimization storage grades are in negative correlation with the use frequency;

s10233, constructing reduced file data corresponding to the original file data in the local storage based on the data optimization storage grade;

Before the reduction operation is performed on the original file data, or after the original file data is acquired from the cloud disk server according to the mapping relationship information, the data storage method of this embodiment further includes:

acquiring the use frequency corresponding to original file data in local storage within a set time period;

when the use frequency is greater than a set threshold value, reserving and storing original file data into a local storage; otherwise, constructing the reduced file data corresponding to the original file data and uploading the reduced file data to the cloud disk server.

In this embodiment, the optimized start algorithm may set multiple thresholds to start different degrees of optimized storage levels of data, for example, 30% of the first-level optimized storage, 60% of the second-level optimized storage, and 90% of the third-level optimized storage. For text type files, the degree of optimal storage can be controlled by controlling how much text content is retained, and other types of files are similar. Therefore, memory optimization of different degrees can be purposefully performed on the stored files according to the use condition of the user, and the purpose of flexibly optimizing storage is achieved.

Specifically, as shown in fig. 8, corresponding to the processing logic of the automatic optimization storage, the optimization start algorithm is used to implement the adaptive optimization of the local storage file, and the optimization start algorithm can calculate and count the file usage frequency. All newly generated files are firstly stored in a local storage, meanwhile, the optimized monitoring service starts monitoring the files, and when the files are frequently used, the optimized monitoring service does not start a storage optimization strategy for the files, so that the files are stored in the local storage in the form of original files. At this time, if there is file access, the original is directly provided for external access, that is, the current storage call logic is an access policy of 1- >4 in the figure. When the file is not used for a long time and reaches the threshold value of the optimization starting algorithm, storage optimization is started, the contracted part is stored in the local storage, and meanwhile the original file is uploaded to the cloud disk. At this time, if there is file access, an original or a contracted piece may be provided according to the user's needs, that is, the current storage invocation policy is 1- >2- >3- >5 in the figure, and finally, according to the user's selection, a corresponding original or contracted piece is provided.

In addition, step S101 further includes a scheme for optimizing storage triggered by an external condition, specifically:

and judging whether a switch control signal is received, if so, executing the step S101. The switch control signal can be triggered by a hardware physical switch, and can also be controlled by a software program, and specifically, which mode can be selected and determined according to actual requirements.

The storage optimization scene controlled by the switch is determined by the user to determine whether the storage optimization strategy is started or not so as to meet the requirement that the user triggers optimization at any time according to the self requirement, and the use experience of the user is effectively improved.

Specifically, as shown in fig. 9, when the storage optimization is triggered by the switch control signal, the processing logic is configured to enable a user to select whether to optimize storage when generating an original, and if the user selects not to execute optimized storage, when accessing the local file from the outside, it may be determined that the locally stored file is of the original type, and then the local storage space may be directly accessed. And if the user selects to execute the optimized storage, uploading the original file to the cloud disk according to a schematic diagram mode, and locally storing the corresponding contracted file. If the external access local file is judged to be the type of the contracted file, the contracted file is acquired from the local storage or the original file is acquired from the cloud disk according to the selection result of the user.

As shown in fig. 10, step S102 includes:

s10241, collecting historical operation behavior data of a user in the terminal equipment;

s10242, performing analysis processing based on historical operation behavior data to determine user operation preference data;

s10243, generating a user preference storage optimization rule according to the user operation preference data, and constructing reduced file data corresponding to the original file data according to the user preference storage optimization rule.
