Below with reference to accompanying drawings the disclosure is described.It should be noted that following being described in is only explanatory and exemplary in essence, never as any restriction to the disclosure and application or use.Unless stated otherwise, otherwise positioned opposite and numerical expression and the numerical value of the parts of setting forth in an embodiment and step do not limit the scope of the present disclosure.In addition, technology well known by persons skilled in the art, method and apparatus may not be discussed in detail, but are intended to the part becoming specification in appropriate circumstances.
In view of existing cloud stores service local virtual dish constructing plan can not the local particular type file of auto-associating (such as, specific file suffixes, specific names file, file modified date etc.), the following embodiment of the disclosure proposes a kind of technical scheme of carrying out cloud Storage Mapping based on strategy, user can be made to realize personalized cloud according to self-demand according to specific policy store, client local file and the file in cloud storage server is made to keep synchronous, thus ensureing on the basis transparent to cloud storage server end, improve flexibility and the ease for use of cloud storage.
Fig. 1 is the schematic flow sheet realizing the method that cloud stores of a disclosure embodiment.
As shown in Figure 1, this embodiment can comprise the following steps:
S102, receive user according to the cloud storage policy of data syn-chronization requirements set, cloud storage policy comprises the mapping to specified attribute file;
First, the data syn-chronization demand of setting according to the local data syn-chronization demand stored to cloud of self-demand setting, can be passed in client the device realizing cloud and store by user.Client generates cloud storage policy according to this demand after receiving this demand, which file synchronization in client can be uploaded in the cloud storage server of network side in this strategy by pointing out particularly.
S104, real-time supervisory user is to the operation of client file;
When user such as create file in client, existing file is modified or the operation such as deletion time, by the files classes operation-interface in operating system, client meeting monitor operating system, such as, can find whether specified attribute file is modified, deletes or creates specified attribute file.
S106, if user has carried out establishment, amendment or deletion action in client this locality to the file meeting cloud storage policy, has then performed corresponding operating to the file in cloud storage server;
The file meeting cloud storage policy due to user customer this locality has carried out change or deletion action, therefore needs this operation to be synchronized on cloud storage server in time.
If user creates in client the file that meets cloud storage policy, then can by existing uploading file in real time by the file of this new establishment from client transmissions to cloud storage server.
If user revises an existing file meeting cloud storage policy in client, then similarly also can utilize existing uploading file in real time by the corresponding document on this amended file covering cloud storage server.
If user deletes the file that meets cloud storage policy on the client, then this deletion action is synchronized on cloud storage server, that is, the corresponding document on synchronization removal cloud storage server.
S108, if user has carried out deletion action in client this locality to the file meeting cloud storage policy, then having determined whether to remove strategy corresponding with deletion action in cloud storage policy according to data syn-chronization demand, as removed, then having upgraded cloud storage policy.
After the file meeting cloud storage policy in user customer carries out deletion action, if client this locality no longer includes the file with institute deleted file with same alike result, then user can delete according to data syn-chronization demand or retain corresponding strategy.If deletion corresponding strategy, when again there is this property file in the client then, no longer to cloud storage server this file synchronous, if retain corresponding strategy, when again there is this property file in the client then, still to cloud storage server this file synchronous.
Such as, user specifies a strategy for the file that suffix is apk, but after this file of deletion, whole client has not had suffix to be the file of apk, and now this strategy is nonsensical.At this moment client needs decision to be delete this strategy or reservation.If retain, when subsequent client occurs that suffix is the file of apk, also can automatic synchronization to cloud storage server end.If deleted, when subsequent client occurs that suffix is the file of apk, then cloud storage server end automatically can not be synchronized to.
In this embodiment, because set strategy maps specified attribute file, this specified attribute file can be arranged in the optional position of client, these files can be associated by specified attribute, then mapping is synchronized to cloud storage server together.Compared with existing virtual disk scheme, synchronous information need not be wanted to be prestored in virtual disk by all, save disk space on the one hand, eliminating unloading process improves synchronous real-time on the other hand.Compared with existing mapping directory scheme, because all specified files to be synchronized can be in the optional position of client, be not limited to assigned catalogue, therefore significantly improve synchronous flexibility.
Wherein, specified attribute file can include but not limited at least one in the file of the file of designated suffix, create name, the file of specifying size, the file of specified file founder and the file of scheduled date, and the file of scheduled date can comprise the specified file date of formation and specified file revises the date.
Such as, need the file being synchronized to cloud storage server to be have the file of jpg suffix and/or have the file etc. of log suffix, suffix can be determined according to synchronisation requirement by user.
The file of create name can be comprise the file of specifying letter and/or designation number in file name.
The file of scheduled date can be only synchronously have the file of scheduled date or the file after or before the synchronous scheduled date.
Specify the file of size can be only synchronously have the file or the file of file size in setting range of specifying size.
The file of specified file founder can be only synchronously have the file of specifying author.
In addition, it is pointed out that and above-mentioned attribute combination can also be formed new file attribute.Such as, designated suffix can be combined with create name, designated suffix was combined with the scheduled date, create name was combined with the scheduled date, or designated suffix, scheduled date are combined with create name three.
Further, the state information of cloud storage policy and specified attribute file can also be stored in policy configuration file.Like this, can as follows in real time supervisory user to the operation of client file:
By comparing with the state information be stored in policy configuration file the change of the file meeting cloud storage policy of being monitored by operating system, wherein, this change can include but not limited to create file, amendment file and deleted file;
Determine that user is to the action type of file meeting cloud storage policy according to comparative result.
In addition, cloud storage policy can also include but not limited to build virtual disk in this locality and directly map local directory.
It is to be noted, together with the above-mentioned mapping to specified attribute file, these three kinds of strategies can combine mutually, such as, build virtual disk in this locality and directly map combined to local directory, build virtual disk in this locality with combined to the mapping of specified attribute file, to the mapping of specified attribute file with directly map combined to local directory, or build virtual disk in this locality, directly map combined to the mapping of specified attribute file and local directory.The result of these strategy configurations can store with the form of policy configuration file, and is synchronized to cloud storage server according to demand.

For needing synchronous data, user needs its storage policy in this locality clear and definite.Such as, comparing dispersion but the data (such as, being distributed in the picture file of different disk subregion, system backup file etc.) all needing to be synchronized to cloud storage for storing in this locality, particular file types can be mapped directly to; Require higher data for fail safe, privacy, the mode building virtual disk in this locality can be adopted to store; Frequent and the local data storing Relatively centralized (such as, under being stored in one or several catalogues) of, regular job not high for security requirement, can map directly to local directory.
For the mode mapping particular file types, the Policy receipt unit in client can guide user to determine concrete file type relevant parameter, then completes tactful configuration operation, configuration result is saved in storage policy configuration file.
Build the mode of virtual disk for this locality, the Policy receipt unit in client can guide user to determine local virtual disk parameter, then completes tactful configuration operation, configuration result is saved in storage policy configuration file.
Carry out the mode of directories/files mapping for this locality, the Policy receipt unit in client can guide user to determine target directory/file, then completes tactful configuration operation, configuration result is saved in storage policy configuration file.
User also can adjust existing local virtual dish strategy, represents existing storage policy by the Policy receipt unit in client, the amendment result of record client, and is saved in policy configuration file.
In virtual disk policy development adjustment flow process, all results are kept in storage policy configuration file, and generate and safeguard the local virtual dish that cloud stores by the monitoring unit in client and operation lock unit, to ensure the file synchronization on client local virtual dish file and cloud storage server.
In daily information data operating process, whether the monitoring unit of client can be operated by the real-time monitor client file of client operating system, when the file operation of user relates to the file of file in specified attribute file, local virtual dish and/or assigned catalogue, by triggering following handling process.
If client creates in this locality, the file of amendment meets cloud storage policy, or user directly creates, have modified file in virtual disk local directory, virtual disk, relevant change will be synchronized to cloud storage server by operation lock unit.
If user deletes the file meeting cloud storage policy in this locality, or user is directly at virtual disk local directory, virtual disk deleted file file, then policy update unit judges whether to delete corresponding strategy according to user's request (such as, target directory or virtual disk has been empty; The all file destinations meeting cloud storage policy are all deleted etc.), and be presented to user by modes such as interfaces.
If user have selected deletion, then carried out the process of corresponding strategies by policy update unit, adjustment stored configuration strategy, and operating result is saved in storage policy configuration file.By operation lock unit, deletion action is synchronized to cloud storage server end simultaneously.If user selects not delete, then directly deletion action is synchronized to cloud storage server by operation lock unit.
It should be noted that, it is completely transparent that client-based method can be accomplished server end, can make full use of existing public cloud storage solution and related resource, is convenient to implement, and is conducive to protecting existing investment.
