Summary of the invention

It is an object of the invention to, it is provided that a kind of data to specifying publicly-owned cloud account carry out the method for automated back-up respectively and are System, it can effectively solve problems of the prior art, it is achieved the content intellectuality respectively that will specify in publicly-owned cloud account Automated back-up is to different storage devices, it is ensured that the safety of data.

For solving above-mentioned technical problem, the present invention adopts the following technical scheme that: a kind of data to specifying publicly-owned cloud account are entered The method of row automated back-up respectively, comprises the following steps:

S1, specifies publicly-owned cloud storage account with certain and multiple with wifi function by the account of individual private possession cloud storage system Storage device is bound；

S2, the subdirectory under each catalogue in described publicly-owned cloud storage account and file are carried out by individual private possession cloud storage system Travel through first, after having traveled through, the subdirectory under respective directories and file name data are derived and preserved to data base；

S3, the subdirectory under each catalogue in data base and file name data are generated multiple tasks by individual private possession cloud storage system Group also waits the storage device active obtaining with wifi function；

S4, after the described storage device with wifi function is networked, obtains task to individual private possession cloud storage system, then Automatically start to download from the publicly-owned cloud storage account of appointment according to the subdirectory under respective directories in current task group and filename and appoint Business data.

Preferably, step S1 specifically includes:

S11, accesses each web management interface with the storage device of wifi function, and utilizes individual private possession cloud storage system Account and the password of system log in；After logging in successfully, each is i.e. deposited with individual private possession cloud with the storage device of wifi function The account of storage system establishes binding relationship；

S12, initiates certain appointment publicly-owned on each described web management interface with the storage device of wifi function The bind request of cloud storage account；Obtain access by the open DLL (i.e. OpenAPI) of publicly-owned cloud storage system to award Power, it is thus achieved that authorize key accordingly；

S13, by the title of described publicly-owned cloud storage system, authorizes key and the equipment with the storage device of wifi function to compile Number it is uploaded to individual private possession cloud storage system and preserves；

S14, individual private possession cloud storage system create multiple different virtual containers so that each virtual container respectively with described finger Each catalogue one_to_one corresponding association in fixed publicly-owned cloud storage account, simultaneously each virtual container with each with wifi function Storage device is carried out one to one, many-one or one-to-many association.

Realized by the account of individual private possession cloud storage system and publicly-owned cloud storage account and with wifi function by said method Storage device is bound, such that it is able to realize individual private possession cloud storage system with the storage device of wifi function and publicly-owned Carry out efficient, safe, steady between storage device and publicly-owned cloud storage system between cloud storage system and with wifi function Fixed communication；Especially by utilize different virtual containers respectively with some specified in publicly-owned cloud storage account or a few Individual catalogue one_to_one corresponding associates, simultaneously each virtual container carry out one to one with the storage device of wifi function with each, many One or one-to-many are associated, such that it is able to utilize each virtual container more accurately, management and control efficiently specify phase in cloud storage account Answer the content backup under catalogue and more new task.

In above-mentioned step S14, divide can to when individual private possession cloud storage system creates multiple different virtual container each container Join a unique mark, when virtual container and certain catalogue specified in publicly-owned cloud storage account and certain is with WiFi function Storage device when binding, individual private possession cloud storage system can record container and uniquely identify and specify publicly-owned cloud storage account In certain catalogue and certain storage device with WiFi function between relation and preserve to individual private possession cloud storage system Data base in.

Preferably, step S2 specifically includes: described different virtual container is in publicly-owned cloud storage account associated there Subdirectory and file under respective directories travel through first, generate data structure (i.e. catalogue and the file of META DATA Structure, further comprises last modification time, file size, MD5 value, whether have been downloaded into wifi function The information such as storage device)；After having traveled through, by described filename according to N number of be one group, after being divided into multiple groups, derive For the data (it is all supported by multiple computer language) of json form, and preserve to data base；Wherein, traversal Time, using subdirectory or file name as index value, with file size, last modification time, MD5 value, whether be catalogue Etc. information as the data block of structure type；Such that it is able to optimize individual's cloud storage system management to backup tasks, it is simple to To the storage device transmission tasks with wifi function.

Step S3 specifically includes: the data in data base are generated multiple task groups according to packet by each different virtual container, And according to being grouped acquisition task after waiting the storage device networking with wifi function；Storage device with wifi function is every Secondary the mission bit stream downloading a packet rather than whole mission bit streams, such that it is able to readily available new task, renewal The performance of task and the pressure of reduction individual's cloud storage platform.

In said method, after the described storage device with wifi function is networked, obtain to individual private possession cloud storage system and appoint Business, is then firstly connected to individual private possession cloud storage system, downloads data backup task；Wherein, all of task is all according to N Individual is one group, all contains the account information of publicly-owned cloud storage system and need from this publicly-owned cloud storage system in every group task File name in the catalogue of backup.

Preferably, step S4 specifically includes: after the storage device networking with wifi function, the state of detection storage device, If Active, then initiating task to individual private possession cloud storage system and obtain request, individual private possession cloud storage system inquires and is somebody's turn to do All virtual containers of equipment association, are then handed down to this equipment by virtual container first task groups not being fully completed； This equipment preserves task definition and the numbering of packet, and according to the subdirectory under respective directories in current task group and filename from Dynamic from specifying beginning downloading task data publicly-owned cloud storage account；Often complete the download of a file or complete a task The download of all or part of file of group, then to corresponding virtual container more new task performance (with depositing of wifi function Storage equipment, when downloading task, obtains unique mark of the virtual container generating this task the most simultaneously) and storage device Residue free space；If the residue free space of storage device is less than preset value, then after abandoning the current group obtained Continue task, and the state arranging storage device is Inactive, stop data synchronization service；Otherwise corresponding virtual container is connecing After the task that receives is more newly requested, search the record of correspondence in a packet according to packet numbering and file name, if finding correspondence File record, then arrange fetched=1 (wherein, each file corresponding a fetched value)；Wherein, Fetched is the member comprised in META DATA structure, for indicate whether to be downloaded to user with The storage device of wifi function, the default value of fetched is 0；If not finding the file record of correspondence, then return false signal To with the storage device of wifi function, after receiving false signal with the storage device of wifi function, abandon having obtained The follow-up work of current group and reacquire first task groups being not fully complete (this represents that grouped task occurs in that renewal, because of This needs to reacquire grouped task)；Often complete the download of a task groups with the storage device of wifi function after, automatically please The next one is asked to be not fully complete task groups, until completing last to be not fully complete task groups.According to the storage device with wifi function Hardware performance, can one by one the task groups in virtual container be processed, or simultaneously in multiple virtual containers appoint Business packet processes.Such that it is able to update list according to data to back up desired data accurately from publicly-owned cloud storage account, carry The efficiency of high data backup and the operational efficiency of whole system.Additionally, arranging fetched is in META DATA structure The member comprised, consequently facilitating the download performance of labelling task；So when under the storage device with wifi function After secondary networking again, being not fully complete of task can be directly downloaded, and need not start anew all to download, alleviate with wifi merit The pressure of the storage device of energy, improves data transmission efficiency；It also avoid when carrying out locally stored space smoothing dilatation simultaneously The problem of the Data duplication backup caused.

In step S4, when detecting the state of storage device, storage device is needed to send its current residual memory space to individual In people's private cloud storage system, individual private possession cloud storage system feeds back its current shape according to the size of preset value to storage device State, for Active or Inactive.

When the state of storage device is Inactive, it is also desirable to periodically reacquire its up-to-date state.

Preferably, in aforesaid method, if the residual memory space of described storage device is less than preset value, the most virtual The state of this storage device is set to Inactive by container, and this storage device stops simultaneously operating；By described storage is set Standby data of deleting are allowed to revert to Active state or by the new storage device of association to this virtual container or virtual Container by other residual memory space associated with it higher than in preset value but storage device that current state is Inactive Individual be set to Active state after, recover data syn-chronization work；Wherein, when virtual container associates multiple storage device, entering During row data syn-chronization, the state of only one of which storage device is Active, and other are Inactive, it is achieved thereby that to this locality The smooth expansion of memory space.

In said method, if the current state of storage device is Active, it is possible to bind new storage device the most virtual to it Container, and if the state of this new storage device be Active, then the upper Active associated with this virtual container The storage device of state can be forced to be set to Inactive, then proceeds data syn-chronization in the storage device that this is new.

It is furthermore preferred that when each catalogue one_to_one corresponding in each virtual container cloud storage publicly-owned with described appointment account associates, with Time with each with the storage device of wifi function carry out many-one associate time, if certain of individual private possession cloud storage system is virtual Container finds the memory space of described storage device less than preset value during performing to synchronize time, then this virtual container is by it It is set to Inactive state with the relation of this storage device；Individual private possession cloud storage system is searched and is notified to set with this storage simultaneously Other virtual containers of standby association, its relation with this storage device is also set to Inactive state by other virtual containers；Number According to synchronous working stop, until described storage device by delete data transfer to Active state or by association new Other residue associated with it is deposited by the storage device with wifi function to each virtual container or each virtual container After storage space is set to Active state higher than in preset value but storage device that current state is Inactive, continue Carry out data syn-chronization work.Such that it is able to all publicly-owned cloud storage that quick, unified control is associated with certain storage device Whether the carrying out of the data syn-chronization work in card of accounts.

Preferably, after the described storage device with wifi function is networked, obtain task to individual private possession cloud storage system, Then under automatically starting from the publicly-owned cloud storage account of appointment according to the subdirectory under respective directories in current task group and filename Load task data specifically includes: parallel processing or serial process；Described parallel processing is i.e. with the storage device of wifi function First obtain first task groups data of all virtual containers associated with this equipment, carry out the most parallel under multiple file Carry；Described serial process the most only obtains the task groups data of a virtual container and carries out file synchronization, has processed one The task data of next virtual container is processed the most successively after all grouped task of individual virtual container.If with wifi function The built-in cpu performance of storage device good, then use parallel processing, if cpu performance is poor, then use serial process； Additionally the read or write speed of storage device also have impact on this selection arranged, and can arrange maximum according to different hardware performances Parallel number of tasks.
