Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of method of media file backup, carried out by subscriber equipment, specifically carried out by the media file back-up device arranging in subscriber equipment, described subscriber equipment comprises the first memory device and the second memory device, why type the embodiment of the present invention does not limit the first memory device and the second memory device memory device, for example, the first memory device and the second memory device can be all following any one memory devices: hard disk, floppy disk, USB flash disk, CD, portable hard drive, disk, storage card, as shown in Figure 1, the method of the media file backup that the embodiment of the present invention provides comprises the following steps:
S11, the media file of storing on scanning the first memory device, to determine whether described media file is marked with vital document mark.
First it should be noted that, in this step, the media file scanning is at least one media file of storing on the first memory device.
For example, in this step, described media file can comprise at least one in audio media files, video media file and picture file.Wherein, audio media files refers to the file of stored sound content, and such as form is the file of MP3, CD, WAVE (* .WAV), WMA, RealAudio etc.; Video media file refers to the file of the various dynamic image contents of storage, and such as form is the file of WMV, AVI, MP4, RM/RMVB, kmv etc.; And picture file refers to the file of the various tangible things contents of storage, such as form is the file of JPEG, TIFF, BMP, GIF, PNG etc.
Obviously, described media file can be also the media file of other types, and the present invention does not limit this.
Be understandable that, that the media file of storing in the first memory device comprises is very important for user, user wants the permanent media file of preserving, in order to guarantee the security of this part media file, in the backup method that the embodiment of the present invention provides, before this step is S11 step, user will be these important media file marking value documents marks.For example, subscriber equipment can provide vital document option for media file, thereby user can be by choosing this option for this media file marking value documents mark; Again for example, subscriber equipment can receive user, and to want mark media file be the instruction of vital document, receiving after this instruction, subscriber equipment adds vital document mark in the attribute information of this media file, the vital document mark that has been this media file mark.Like this, in this step, subscriber equipment can, by scanning, find these important media files, and then these important media files are backed up, and effectively guarantees the security of these media files.
Concrete, this step can have three kinds of specific implementations, as follows respectively:
One, in one embodiment of the invention, subscriber equipment can receive user's scan instruction, and described scan instruction is indicated in the situation that the media file of storing on described the first memory device is scanned, according to user's scan instruction, scan the media file of storing on described the first memory device, to determine whether described media file is marked with vital document mark; That is to say, this step can be carried out according to user's wish, and user can, according to the actual needs of oneself, issue scan instruction at any time.For example, subscriber equipment can provide for user the function choosing-item of scanning medium file, in the time that user selects this function choosing-item, starts to carry out this step.
Its two, subscriber equipment can be according to the scan period setting in advance, the media file of storing on scanning the first memory device, to determine whether described media file is marked with vital document mark.The length of this scan period setting in advance is not limit, and can arrange arbitrarily, and for example 1 day, 1 week, 2 weeks, one month etc., this scan period can be that user sets in advance, and can be also the default setting of subscriber equipment.
They are three years old, subscriber equipment can the operation of Real-Time Monitoring user to the media file of storing on the first memory device, determine that user operates the media file of the first memory device, stores once monitor, the media file that scanning user was operated, to determine whether the media file that user operated is marked with vital document mark.Here " operation " that the subscriber equipment sayed is monitored, can comprise that user pastes new media file in the first memory device, user opens in the first memory device and originally after the media file of storage, closes, or, user revises the content of the media file of originally storing in the first memory device, or user revises attribute of the media file of originally storing in the first memory device etc., the present invention does not limit this.For instance, in the first memory device, paste new media file once subscriber equipment detects user, will start to scan this new media file, to determine whether this media file is marked with vital document mark.
Be understandable that, in one embodiment of the invention, at least two kind modes of subscriber equipment in can compatible above-mentioned three kinds of modes scan.
It should be noted that the present invention does not limit the specific implementation of this step, can be at least one in above three kinds of modes, can also be other scan modes.
In this step, if user equipment scans is marked with vital document mark to media file, execution step S12, and the media file identifying for unmarked vital document, subscriber equipment can not carry out any processing.
S12, if described media file is marked with vital document mark, obtains the directory information of described media file.
It should be noted that, in the embodiment of the present invention, directory information refers to the routing information that on memory device, media file is deposited.For example, the directory information of certain media file be " E: Beijing Company research and development department 1 communication set work courseware .wma ".
Concrete, subscriber equipment can read the attribute information of the media file that is marked with vital document mark, obtain the directory information of this file, certainly, subscriber equipment can also have other to obtain the mode of directory information, the embodiment of the present invention does not limit this, specifically can, referring to prior art, repeat no more here.
S13, according to the described media file directory information obtaining, backups to described media file on the second memory device.
On the second memory device, can be provided with special back-up storage district, in this step, subscriber equipment can backup to the media file that is marked with vital document mark in the back-up storage district in the second memory device.
The method of the media file backup of the embodiment of the present invention, scan the media file of storing on the first memory device, in the time that described media file is marked with vital document mark, according to the directory information of this file, this media file is backuped on the second memory device, that is to say, can automatic benchmarking's note there is the media file of important media file mark to back up, so, only need user to carry out mark to important media file, complete backup without operations such as user manually copy, therefore effectively simplified the troublesome operation that user backs up, can also avoid preferably forgeing or omitting the File lose causing due to user, effectively guarantee the security of backup, thereby obviously improving user experiences, and without increasing any chip, effectively reduce cost.
Be understandable that, in the embodiment of the present invention, before S11 step, the vital document marking value documents mark that user need to think to it, that is to say, subscriber equipment need to, under user's indication, be media file marking value documents mark according to user's requirement, is that the important media file mark of media file mark is elaborated below to subscriber equipment.
Concrete, in the backup method of the media file providing in the embodiment of the present invention, subscriber equipment comprises following two kinds to the method for the important media file mark of media file mark, but is not limited to following two kinds:
One:
In the time that user need to close media file; user can click the X button of this media file conventionally; issue out code; at this moment; subscriber equipment can be in the time receiving user to the out code of media file; send the prompting of vital document mark to described user; for example; eject a dialog box; in dialog box, show: whether be this file marking value documents mark; and provide the OptionButton of "Yes" and "No", point out user whether as its media file marking value documents mark of closing to inquire.If user thinks that this file is important, to send the instruction of marking value documents mark according to the prompting of vital document mark, for example, click the "Yes" button in dialog box, equipment for indicating user is this media file marking value documents mark, subscriber equipment receives after this instruction, the media file marking value documents of closing for user identifies, certainly, if user thinks that this file is inessential, without mark, can send without mark instructions according to the prompting of vital document mark, for example, click the "No" button in dialog box, equipment for indicating user need not be this media file marking value documents mark.
Be understandable that, this mode is not limited to user in the time closing media file, can also realize on other opportunitys, for example, in the time that user preserves media file, for example, user is modifying to a media file etc. after operation, conventionally can click save button or drop-down menu " save option ", issue and hold instruction, subscriber equipment can be in the time receiving user to the holding instruction of media file, eject the prompting of vital document mark, thereby point out according to vital document mark under the instruction issuing user, carry out marking operation or do not carry out marking operation, here repeat no more.
It should be noted that, for example, what subscriber equipment sent vital document mark prompting to user can be the form that ejects dialog box, to inquire whether mark of user, if user thinks mark, selects to be, otherwise selects no.Certainly, the prompting mode of subscriber equipment is not limited to this mode, can also be other modes.
Its two:
When user runs into it at every turn and thinks important media file, can adopt the mode that this media file is edited, be this media file marking value documents mark.Concrete, user will issue the edit instruction for this media file to subscriber equipment, in the embodiment of the present invention, described edit instruction can refer to that user wants any operation of editing media file, for example, click the mouse at the icon place of the media file operation of right button of user, user clicks operation of button etc. arbitrarily in the toolbar of media file or menu bar, in the time that subscriber equipment detects user's this operation, to operate corresponding media file editing options with user for user shows, for example, eject drop-down menu, this drop-down menu comprises at least one editing options, comprise at least one shown editing options the option that marking value documents identifies, the option of user by selecting marking value documents mark carrys out this media file of mark, it is the selection instruction that subscriber equipment receives the option of user to described marking value documents mark, thereby be the media file marking value documents mark that user edits according to this instruction.
For example, user's edit instruction can be chosen certain media file for user first clicks left button, then clicks right button, at this moment, subscriber equipment will demonstrate editing options menu, and comprising " vital document mark " option, and then user chooses this option to carry out mark to this media file.
