DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

In addition, in describing this invention, the same code | symbol is attached | subjected and the repeated description is abbreviate | omitted.

First, the configuration of the entire system for implementing the automatic backup system and method using the mobile storage device according to the present invention will be described with reference to FIG.

As shown in FIG. 1, the entire system for implementing the present invention includes a computer terminal 10, a mobile storage device 30, an update server 50, and a storage server 60. The computer terminal, the update server, and the storage server except for the mobile storage device 30 are connected to the communication network 20 such as the Internet.

The computer terminal 10 is a terminal having a computing function, and means a personal computer (PC), a notebook computer, a netbook, a PDA, and the like. The computer terminal 10 has a terminal (or port) for connecting a peripheral device, in particular a storage device. In general, the computer terminal 10 exchanges data with peripheral devices through a standardized bus standard. One of the most common bus specifications is Universal Serial Bus (USB).

The mobile storage device 30 is a removable storage device, and typically includes a USB memory. USB memory mainly uses flash memory. However, the mobile storage device 30 may correspond to any removable storage device such as an external hard disk or a ZIP disk using a USB bus standard.

The update server 50 and the storage server 60 are a kind of server connected to the Internet. In particular, the servers are connected to the computer terminal 10 via the Internet to transmit and receive data. The FTP standard is typically used as a communication standard for transmitting and receiving data. However, the present invention is not limited thereto, and any communication standard capable of transmitting and receiving data can be applied.

The update server 50 stores the automatic backup program stored in the mobile storage device 30 in the latest version, and is updated by the request of the mobile storage device 30 or the computer terminal 10 connected to the mobile storage device 30. Send the version. When the mobile storage device 30 or the computer terminal 10 transmits the version of the automatic backup program owned to the update server 50, the update server 50 compares the transmitted version with the version of the program held by the mobile server. If it is older than yours, transfer the latest version of the program.

The storage server 60 is a server that backs up and stores files (or folders) stored in the mobile storage device 30 or the computer terminal 10. There are two ways of backing up: updating changed files and saving new files every time. For example, when the storage server 60 backs up a file A, and the computer terminal 10 changes the file A to A ', the storage server 60 replaces the previous file A with the changed file A'. This is an electron. The latter keeps file A and A '.

The update server 50 and the storage server 60 are logically distinguished. That is, the servers may be implemented in one physical server.

Next, the configuration of the mobile storage device used in the present invention will be described with reference to FIGS. 2 is a block diagram of a specific configuration of a mobile storage device, and FIG. 3 is a block diagram of a configuration of a flash memory of the mobile storage device according to an embodiment of the present invention.

In one embodiment of Figure 2 is a portable storage device is a USB memory. As shown in FIG. 2, the mobile storage device 30 is largely divided into a flash memory 40 for storing data and a portion for controlling storage (a box portion indicated by a dotted line in FIG. 2).

That is, the mobile storage device 30 includes a program memory 31, a data memory 32, a sector memory 33, a multiplexer (MUX) 34, an address decoder 35, and a flash in addition to the flash memory 40. It is composed of a control unit 36, a USB interface 37, and a USB control unit 38.

The program memory 31 is a memory that stores control program codes for the USB memory to operate the USB mass storage device. The data memory 32 is a memory for storing data necessary for controlling the USB memory. For example, data for sector mapping of an FTL (Flash Translation Layer) is stored. The sector memory 33 is a memory for storing the first code executed when the USB memory is inserted into the computer terminal 10.

A multiplexer (MUX) 34 selects one of the three memories for control to read (or write) data. The flash controller 36 controls the interface to read or write data stored in the flash memory 40. The address decoder 35 interprets the address to determine which of the program memory 31, the data memory 32, the sector memory 33, and the flash memory 40 is read (or written).

The USB interface 37 interfaces with the USB host 15 as an element for connecting with the USB port of the computer terminal 10. The USB host 15 is a program installed in the computer terminal 10 to recognize a USB device and to control communication.

On the other hand, as shown in Figure 3, as an embodiment of the present invention, the flash memory 40 of the mobile storage device 30 is divided into a hidden area 41 and a public area 42.

The hidden area 41 is an area for storing the program code of the automatic backup system according to the present invention. The open area 42 is a general storage space of the flash memory 40 in which a user can store data.

The hidden area 41 is a storage space which is used only by the system and is inaccessible to the user by partially allocating the flash memory 40 from the time of manufacture according to the present invention.

In contrast, the public area 42 is a storage space in which a user can store data. For reference, USB memory is generally classified into a secret area where data can be accessed by a user set password and a general area that can be accessed without a password. The hidden area 41 and the secret area are different concepts and should not be confused. That is, the generally speaking secret area and the general area correspond to the public area 42.

Next, a configuration of the automatic backup system installed in the mobile storage device according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5.

As shown in FIG. 4, the automatic backup system 70 according to an embodiment of the present invention includes a program starter 71, a program loading unit 72, a program updater 73, and a synchronization program 80. do.

The program starter 71 is a program part that is automatically executed when the mobile storage device 30 is inserted into the computer terminal 10. In particular, the program code of the program start section 71 is stored in the sector memory 33 of the mobile storage device 30.

When the mobile storage device 30 is inserted into the computer terminal 10, the portion stored in the sector memory 33 is automatically read and executed. However, since the capacity of the sector memory 33 is extremely small, only a small amount of code can be stored.

Therefore, if the capacity of the program code of the program start section 71 is larger than the storage capacity of the sector memory 33, the program code of the program start section 71 is stored in the flash memory 40 and the flash memory is stored in the sector memory 33. The code indicating the address of the program code stored in 40 is stored.

That is, when the mobile storage device 30 is inserted into the computer terminal 10, the computer terminal 10 reads the start address of the code stored in the sector memory 33 into the flash memory 40, and thus the flash memory 40. Run the program code stored in.

The synchronization program 80 is a program code for synchronizing or backing up a folder stored in the computer terminal 10 with a folder stored in the flash memory 40 or the storage server 60 of the mobile storage device 30. The synchronization program 80 is stored in the flash memory 40 of the mobile storage device.

The program update unit 73 is executed by the program start unit 71. The program updater 73 accesses the update server 50 described above and updates the synchronization program 80 with the latest version program stored in the update server 50.

The code of the synchronization program 80 includes version information of the program. When the program update unit 73 transmits the version information currently stored in the mobile storage device 30 to the update server 50, the update server 50 checks the received version information to obtain the latest program code if it is not the latest version information. send. The program updater 73 receives the latest synchronization program 80 from the update server 50 and updates the synchronization program 80 stored in the mobile storage device 30.

The program loading unit 72 installs and executes the synchronization program 80 in the computer terminal 10. When the program updater 73 updates the synchronization program 80 with the latest information, the program loading unit 72 is executed to load the synchronization program 80 into the computer terminal 10. The synchronization program 80 is loaded into the computer terminal 10 to perform synchronization or backup.

Meanwhile, the synchronization program 80, the program update unit 73, and the program loading unit 72 are stored in the flash memory 40 of the mobile storage device 30. In addition, some codes or all of the program starter 71 may be stored in the flash memory 40. In this case, as described above, the introduction portion or the position information of the program code of the program start section 71 is stored in the sector memory 33 of the mobile storage device 30.

As described above, the flash memory 40 of the mobile storage device may be divided into a hidden area 41 and a public area 42. When divided, the program codes, that is, program codes of the synchronization program 80, the program updater 73, and the program loading unit 72 are stored in the hidden area 41. In this way, the user can not change the program code associated with the system, thereby enhancing the security of the system.

Next, the synchronization program 40 will be described in detail.

As shown in FIG. 5, the synchronization program 80 includes a synchronization manager 81, a mobile medium synchronizer 82, and an online synchronizer 83. In addition, the vaccine management unit 84, life state display unit 85 may be further included. Further, the apparatus further includes a synchronization information storage unit 86 for storing necessary data.

The synchronization manager 81 checks whether the folder of the computer terminal 10 is synchronized with the folder stored in the flash memory 40 or the storage server 50. The way to check for synchronization is to compare the date and time of the latest update of the files in the folder so that you can see which file is out of sync and which file is older.

In this case, the folder may mean a place for storing a general file, but may also be interpreted as specific files. In other words, it is preferable that the user wants to backup or synchronize the folder as a folder. However, it is also possible to designate specific files for backup or synchronization. Thus, in the latter case, the folder can be interpreted as a file.

The synchronization manager 81 performs an authentication process to access the storage server 50. In order to back up a file to the storage server 50, authentication information for the mobile storage device 30 or the user must be registered in the storage server 50. User authentication may be used, such as a user ID or password. In addition, authentication information using a user's official certificate, the user's biometric information, etc. can also be utilized. It is also possible to register authentication information by the mobile storage device 30. For example, authentication information may be registered through a product unique number of the mobile storage device 30.

The synchronization manager 81 may receive and process authentication information from the user every time the authentication is performed by accessing the storage server 50, but may store the authentication information and use the stored authentication information.

When the authentication is completed and the folders are not synchronized, the synchronization manager 81 performs the mobile medium synchronizer 82 and the online synchronizer 83 to perform synchronization or backup. That is, if the folders are not synchronized, the mobile medium synchronizer 82 synchronizes or backs up the folder of the computer terminal and the folder stored in the flash memory, and the online synchronizer 83 does not synchronize the folders. Synchronize or back up the folder of the computer terminal and the folder stored in the storage server.

Meanwhile, the synchronization information storage unit 86 receives and stores a synchronization rule. The synchronization manager 81 reads the synchronization rule from the synchronization information storage unit 86, checks whether the synchronization rule is synchronized according to the synchronization rule, and backs up or synchronizes the synchronization rule 82 or online synchronization. Command the base 83.

Synchronization rules include: whether to synchronize or back up, folders to synchronize or back up, whether to overwrite or add to backup, media type of synchronization or backup, location information of storage server, authentication information of storage server, Rules for synchronization or backup schedule information.

Through the screen as shown in FIG. 6, the synchronization rule is input by the user.

Synchronization or backup is a rule that decides whether to synchronize or backup. Backup means unilaterally storing a copy of one file on the other side, and synchronization means comparing the latest update date / time of both files and replacing them with the latest ones. For example, it is assumed that the file A of the computer terminal 10 is May 5 and the file A stored in the mobile storage device 30 is May 8. If the backup to the mobile storage device is selected, the file A of the mobile storage device 30 is updated to a file A of 5 May. On the other hand, if the synchronization is selected, the file A of the computer terminal 10 is updated with the file of May 8th.

The folder to be synchronized or backed up means a backup / synchronization target folder of the computer terminal 10 or a backup folder of the mobile storage device 30 or the storage server 60. If a backup / synchronization target folder of the computer terminal 10 is designated, files belonging to the folder and all files belonging to the subfolder are targeted. In FIG. 6, the input fields 1 to 4 correspond to this.

Whether to overwrite or add to a backup is to choose whether to back up or update the backed up files. For example, it is assumed that the file B stored in the computer terminal 10 is backed up to the mobile storage device 30, and the file B is changed to the file B 'and backed up again. In this case, if the overlapped storage is selected, the file B backed up to the mobile storage device 30 is updated to the file B '. If additional storage is selected, the file B 'is further backed up while the file B backed up in the mobile storage device 30 is left. In FIG. 6, the selection item of display 10 corresponds to this.

The media type of synchronization or backup is a rule for selecting whether to backup / synchronize only to the mobile storage device 30, backup / synchronize only to the storage server 60, or backup / synchronize to both. This corresponds to the selection item of display 5 in FIG. 6.

The location information of the storage server refers to URL information of the storage server 60. Any information other than URL information that can indicate the location of the server can be applied. In FIG. 6, the input field of display 6 corresponds to this.

The authentication information of the storage server is authentication information for the user or mobile storage device 30 registered in the storage server 60. In FIG. 6, the input fields of displays 7 and 8 correspond to this.

The schedule information of synchronization or backup is information that determines when to perform the synchronization / backup operation. In particular, the present invention provides, as a rule, the option of automatically backing up / synchronizing when the computer terminal 10 is shut down when the mobile storage device 30 is inserted into the computer terminal 10. In addition, you can choose to perform backup / synchronization operations at regular time intervals or when specific events occur. That is, it can be regularized. This corresponds to the selection item of display 9 in FIG. 6.

Meanwhile, the synchronization rule may be determined differently for each computer terminal 10. For example, if the mobile storage device 30 is mainly inserted into the computer terminal P1 and the computer terminal P2, the synchronization rule when inserting into the computer terminal P1 and the synchronization rule when inserting into the computer terminal P2 may be different. have.

The vaccine management unit 84 executes the vaccine program to inspect the mobile storage device. The antivirus program of the computer virus is included in the synchronization program 80 and stored in the flash memory 40 of the mobile storage device.

The life state display unit 85 displays the life state of the flash memory 40 of the mobile storage device. Since the flash memory 40 of the mobile storage device is a flash memory of limited lifetime, the flash memory 40 of the mobile storage device should display the life state of the current state to the user. This is to prevent the loss of important files due to sudden end of memory life.

Next, an automatic backup method installed in the mobile storage device according to an embodiment of the present invention will be described with reference to FIG. 7. The automatic backup method installed in the mobile storage device according to the present invention is a computer terminal 10, the update server 50, the storage server 60 is connected to the Internet, the automatic backup system 70 is a mobile storage device 30 When the mobile storage device 30 is inserted into the computer terminal, the automatic backup system 70 is executed to transfer the folder stored in the computer terminal 10 to the mobile storage device 30 or the storage server 60. How to sync or backup the saved folder.

As shown in FIG. 7, the automatic backup method installed in the mobile storage device includes: (a) step (S10) of automatically starting a program of the automatic backup system when the mobile storage device is inserted into a computer terminal; (b) accessing the update server and updating the synchronization program of the automatic backup system with the latest version program stored in the update server (S20); (c) installing and executing the synchronization program in the computer terminal (S30); (d) checking, by the synchronization program, whether a folder of the computer terminal is synchronized with a folder stored in the mobile storage device or the storage server (S40); (e) If the folders are not synchronized, the synchronization program is configured to synchronize or back up the folder of the computer terminal with the folder stored in the mobile storage device or the storage server (S50).

In particular, the program start part is stored in the sector memory 33 of the mobile storage device 30, and the synchronization program 80 is stored in the flash memory 40 of the mobile storage device 30.
