Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter of the present invention is not limited to the following examples, and any technique realized based on the contents of the present invention is within the scope of the present invention.
Example 1
An intelligent data synchronization method based on cloud storage is shown in fig. 1, and includes the following steps:
s1, a data transmission link is established between at least one intelligent terminal device and a home cloud disk, a data transmission link between the home cloud disk and a mobile cloud disk is established, a file synchronous backup state table is stored in the home cloud disk, and a terminal synchronous backup state sub-table is stored in the intelligent terminal device.
The intelligent terminal device can be a mobile phone, a tablet personal computer and the like, when the link between the intelligent terminal device and the household cloud disk is established, the backup between the intelligent terminal device and the household cloud disk can be realized, and because the intelligent terminal device, the mobile cloud disk and the household cloud disk are usually established due to the fact that the intelligent terminal device, the mobile cloud disk and the household cloud disk are convenient to carry when people go out, the intelligent terminal device, the mobile cloud disk and the household cloud disk can be linked, and the intelligent file synchronization and the backup of data among the intelligent terminal device, the mobile cloud disk and the household cloud disk can be realized. The constructed link system has the concept of a 'family domain', and a user, the intelligent terminal equipment, the mobile cloud disk and the family cloud disk all belong to the same family domain. Each user has a unique ID within the home domain.
The intelligent terminal device always belongs to a certain user, and the certain user can simultaneously own a plurality of intelligent terminal devices. The mobile cloud disk belongs to a family domain, and one family can have a plurality of mobile cloud disks, but generally only one family cloud disk. The mobile cloud disk and the family cloud disk also belong to a family domain, generally, the family cloud disk is fixedly stored in a place which is considered to be reliable and safe by a family domain user, the mobile cloud disk stores data which is the same as the family cloud disk, can be considered as backup of the family cloud disk, and is convenient to carry when the family cloud disk goes out. The mobile cloud disk and the home cloud disk can be used by all users in the home domain at the same time.
In order to use the mobile cloud disk and the home cloud disk to backup and synchronize data, the user's smart terminal needs to join the home domain first. The unique home domain to which the mobile cloud disk and the home cloud disk device belong is stored in the internal memory of the mobile cloud disk and the home cloud disk device permanently.
For each user, a corresponding storage space is arranged on the home cloud disk of the home domain, and the data of the user is stored.
The data transmission link established among the intelligent terminal device, the mobile cloud disk and the family cloud disk can be established through a public network or an intranet, the mobile cloud disk and the family cloud disk are accessed through the public network, the risk of data leakage is still caused in the transmission process, however, if the intelligent terminal device, the mobile cloud disk and the family cloud disk transmit data through the intranet, the risk of data leakage in the transmission process is avoided, and the mobile cloud disk and the family cloud disk are private storage spaces, so that the data safety is improved.
And S2, synchronously modifying the contents of the file synchronous backup state table and the terminal synchronous backup state sub-table through a preset file synchronous backup control program, and realizing data synchronous management between the intelligent terminal device and the home cloud disk, wherein the data synchronous management comprises backup, deletion and recovery.
Data synchronization management among the intelligent terminal device, the mobile cloud disk and the home cloud disk is achieved through a file synchronization backup control program, and the intelligent terminal device, the mobile cloud disk and the home cloud disk are all provided with the file synchronization backup control program. The file synchronous backup control program installed on the intelligent terminal device can execute operations of backup, deletion, recovery and the like of files on the local device, and can also monitor operations of other programs (such as a camera, a picture and video processing APP and the like) on the device on backup, deletion, recovery and the like of the files.
The file synchronous backup control program also maintains a file synchronous backup state table in the home cloud disk and a terminal synchronous backup state sub-table in the intelligent terminal device. This file synchronous backup status table records, for each file (which has not been selected by the user for complete deletion), its basic information (name, generation time, place, etc.), and its synchronous backup-related status information, but does not contain the file data itself.
The terminal synchronous backup state sub-table on the intelligent terminal device is only related to folders and files (such as files generated by a mobile phone camera, a picture and video processing APP and the like) which need to be synchronously backed up by the local computer. On the intelligent terminal device, the "synchronous backup state" (first terminal state information) of each file is as follows: a backup is not performed; has been backed up to the mobile disk; has been backed up to the home disk; backing up to the mobile disk; locally deleted files, etc. (these status items are multiple-choice, not mutually exclusive). The terminal synchronous backup state sub-table establishes a sub-table directory structure according to the document structure of the intelligent terminal device, wherein the content of the sub-table directory structure comprises a disc character, the name of a terminal folder or file under the disc character, and first terminal state information corresponding to the name of the sub-table of the terminal folder or file.
On a mobile cloud disk and a home cloud disk, a file storage space and a corresponding file synchronous backup state table are maintained for each terminal device of each user using the cloud disk. The file storage space stores files backed up from the intelligent terminal equipment, and the directory structure of the files corresponds to the directory structure of the video and photo files on the intelligent terminal. On the mobile cloud disk, the "synchronous backup state" of each file is as follows: has been backed up to the present mobile disc; has been backed up to the home disk; local deleted; restored to the intelligent terminal, etc. On a home cloud disk, the "synchronous backup state" of each file is as follows: the home cloud disk is backed up; local deleted; the intelligent terminal is recovered; has reverted to a mobile cloud disk, etc.
The file synchronous backup state table adopts an intelligent data directory structure, the data directory structure is as shown in fig. 2, and a three-level hierarchical tree type directory structure is mainly adopted to uniformly manage data files so as to facilitate management and operation of user data. And the data directory structure adopts the same data storage mode in the mobile cloud disk and the home cloud disk so as to facilitate data backup and synchronization between the mobile cloud disk and the home cloud disk.
The user directory mainly aims at distinguishing different users, each user has a special directory structure and is logically isolated from other user directory structures, and data stored by each user cannot be accessed and copied by other users unless authorized by the user, so that the data security is greatly improved.
Each user may have multiple mobile devices, and for convenience of user data usage, a hierarchical tree directory structure supports multiple devices for each user.
The directory under each device is a final data file directory of the user, and the data directory is mainly directories such as folders and files generated by other applications on the device and stores different types of user data respectively, so that the user can conveniently manage, access, store, back up, synchronize and the like.
Files stored in an intelligent private storage system adopt a special file encryption processing algorithm, and only mobile phone users authorized and registered by an administrator can perform data file operation, so that the data security can be effectively improved, and the personal data privacy is protected from being leaked; meanwhile, the portable mobile cloud disk is not worried about that even if the portable mobile cloud disk is lost carelessly, the data file can not be read and copied.
The data backup and synchronization can realize a plurality of data backup and synchronization mechanisms such as one key, timing, manual operation, automatic operation and the like in daily use in the future as long as the user finishes initial configuration (system data backup and synchronization options), and the synchronous operation is not required to be carried out every time, thereby greatly facilitating the use and operation of the user.
The file synchronous backup program in each device manages a corresponding 'file synchronous backup state table' (corresponding to a terminal synchronous backup state sub-table in the intelligent terminal device), realizes the functions of file synchronization, backup, deletion, recovery and the like of data among the mobile cloud disk, the home cloud disk and the intelligent terminal, and automatically updates and maintains the 'file synchronous backup state table' mutually.
The file synchronous backup state table is an index summary of information and states of all files in each device of the cloud storage system, the file synchronous backup state table stores information and states of each file or folder in each device of the cloud storage system, and the information mainly comprises names of the files and folders, generation or modification time, generation places, devices generated in the devices and the like;
the file or folder state mainly includes two main types, one is that the file or folder has been updated, but the state has not been really executed by the file synchronization backup program, and these states mainly include "backup or synchronization", "local deletion", "complete deletion", "restore", and the like of the file or folder.
The other is that the file or folder has been executed by the file synchronization backup program in the state specified in the "file synchronization backup state table", and these states mainly contain "backed up or synchronized", "deleted locally", "restored", and the like of the file or folder.
A structure diagram of an intelligent data synchronization system based on cloud storage is shown in fig. 3, the system comprises a plurality of intelligent terminal devices and a home cloud disk,

The intelligent terminal device and the household cloud disk are respectively stored with a file synchronous backup control program and a file synchronous backup state table, the file synchronous backup control program is used for backup, deletion and recovery of data between the intelligent terminal device and the household cloud disk, and the file synchronous backup state table and the terminal synchronous backup state sub-table set the state information of the files in real time according to backup, deletion and recovery operations of the data.
Another structure diagram of an intelligent data synchronization system based on cloud storage is shown in fig. 4, and includes multiple intelligent terminal devices, a home cloud disk, and a mobile cloud disk.
A bidirectional data transmission link is established between the intelligent terminal equipment and the home cloud disk, a bidirectional data transmission link is established between the home cloud disk and the mobile cloud disk, the home cloud disk is fixedly arranged, and the mobile cloud disk can be carried about and is used as a backup of the home cloud disk;
the intelligent terminal device stores a file synchronous backup control program, a terminal synchronous backup state sub-table and a file synchronous backup control program which are used for backup, deletion and recovery of data among the intelligent terminal device, the home cloud disk and the mobile cloud disk, and the file synchronous backup state sub-table sets state information of files in real time according to backup, deletion and recovery of the data.
Example 2
The method and the system for managing the data comprise the following specific steps of:
file backup operations
On the intelligent terminal device (mobile phone, tablet), every time a new file is generated (user takes a picture, processes a picture, records a video and the like by using various APPs), the file synchronization backup control program adds a new item on the file synchronization backup state table aiming at the file, and the state is 'non-execution backup'. When a user uses a file synchronous backup control program on the intelligent terminal device to perform file backup, the program scans a file synchronous backup state table, and transmits files with the state of 'non-execution backup' to a certain cloud disk (a preferred family cloud disk and a mobile cloud disk) for backup.
If the backup is successful, the backup state of the file on the intelligent terminal is 'backed up to the home cloud disk' or 'backed up to the mobile cloud disk'. To save local space, the user may choose to delete the local file automatically after the backup is completed (if the backup status of the file on the terminal is increased by a "local deleted" item after such backup is completed). Meanwhile, because the mobile cloud disk or the home cloud disk backs up the file, a new item is added to the file synchronization backup state table, and the state is 'backed up to the mobile disk' or 'backed up to the home disk'.
When the connection between the mobile cloud disk and the home cloud disk is available, the user can directly operate the mobile cloud disk (for example, press a certain special function key of the mobile cloud disk) to perform data synchronization between the mobile cloud disk and the home cloud disk. At this time, the program on the mobile cloud disk scans the file synchronization backup state table, and transfers the file whose state is "backup executed" but does not include "backup to home cloud disk" to the home cloud disk for backup. If the backup is successful, the backup state of the file on the mobile cloud disk is 'backed up to the home cloud disk'. In order to save the local space of the mobile cloud disk, the user can select to automatically delete the local file of the mobile cloud disk after the backup is completed (if the backup state of the file on the mobile cloud disk is added with a local deleted item after the backup is completed). Meanwhile, because the home cloud disk backs up the file, a new item is added on the file synchronous backup state table, and the state is 'backed up to the home cloud disk'.
And (3) file deletion operation:
if the user only deletes a certain file (such as photographing, picture processing, video recording and the like by various APPs) in the intelligent terminal equipment on the intelligent terminal equipment, and the file is not backed up and synchronized on a home cloud disk or a mobile cloud disk from generation to the present, after the user deletes the file, the file synchronization backup program on the intelligent terminal equipment does not perform any operation on the file synchronization backup state table.
If the user only deletes the designated file stored in the intelligent terminal device, and the file is the file which is backed up and synchronized to any device of the family cloud disk or the mobile cloud disk before the user, at the moment, the user only deletes the file stored in the intelligent terminal device when deleting the file; a file synchronous backup program for updating the file state of the file in the intelligent terminal device on the terminal synchronous backup state sub-table to be locally deleted; but the storage state attribute of the file in the home cloud disk or the mobile cloud disk is still stored in the file synchronization backup state table in the home cloud disk or the mobile cloud disk.
If the user wants to delete the designated file completely, and the file is backed up and synchronized to any one of the home cloud disk or the mobile cloud disk before the user selects to delete the file completely, the file stored in the intelligent terminal device is deleted firstly, and the file synchronous backup program updates the states of the file synchronous backup state table and the terminal synchronous backup state sub-table to be 'deleted locally + deleted in the home cloud disk' or 'deleted completely'.
When the home cloud disk, the mobile cloud disk and the intelligent terminal are synchronously connected and available in the whole home domain, a file synchronous backup program in each device automatically scans a file synchronous backup state table according to each file state attribute in the file synchronous backup state table. If all the devices in the home domain completely delete a specified file, the state attribute of the file in the file synchronization backup state table of each device of the file is synchronously deleted, and the file is not visible in the file synchronization backup state tables of all the devices after the file is completely deleted.
And (3) file recovery operation:
the file recovery function can recover specified files which are not completely deleted and stored on the home cloud disk, the mobile cloud disk and the intelligent terminal, and any file which is not completely deleted can be recovered through a file synchronization backup program in each device as long as any device of the three devices stores the file to be recovered.
When the intelligent terminal device needs to restore a specified file, namely a file which is deleted locally on the intelligent terminal device before (for example, a certain special function key of a mobile cloud disk is pressed), the file state can be modified on a file synchronization backup state table to be restored to the intelligent terminal through a file synchronization backup program aiming at the file, when the connection between the mobile cloud disk or the home cloud disk and the intelligent terminal device is available, the file is firstly selected to be restored from the home cloud disk, if the file does not exist in the home cloud disk, scanning is selected to be restored from the mobile cloud disk, and when the file is successfully restored, the file synchronization backup program updates the file synchronization backup state table in the device to be restored.
