Description

Technical Field [0001] The present invention relates to a network storage system for restoring data,

The present invention relates to a network storage system for restoring data, and more particularly, to a network storage system for restoring data, in which a data file and a snapshot file are stored in a space connected to a user terminal through a network, To a network storage system for restoring data.

In general, a hard disk installed in a user's computer such as a desktop or a notebook is used as a local disk and physically fixed to a user's computer. Such a local disk has advantages of high data storage capacity, high accessibility, and high speed.

However, the local disk has a disadvantage in that it is difficult to share data on the network and the mobility in spite of the advantages described above, and a local disk must be purchased separately for capacity expansion.

Companies and individuals with large amounts of data are increasingly using data stored in remote locations separately from computers. In order to prevent loss of data, the user saves the backup data generated in the remote storage to prevent damage to the data, and can restore the data by calling the backup data stored in advance in case of need.

1 is a block diagram of a file recovery system according to the prior art.

The file recovery system of the related art can upload all kinds of files used by individual terminals such as an OS, an application program, a data file, and an e-mail file to a storage installed in a remote location and download desired information of a desired date So that damage to data caused by various reasons such as viruses, carelessness, aging, etc. can be minimized.

The file recovery system is composed of a customer terminal 13 used by a customer such as an individual or a company, a storage 11 storing a file provided from the customer terminal 13, And a server 15 that uploads the data provided from the customer terminal 13 to the storage 11 and provides the data stored in the storage 11 to the customer terminal 13 when a request is made from the customer terminal 13. [

All the files to be uploaded to the storage 11 are processed by the security module 40 at the customer terminal 13 and then transferred to the server 15 and stored in the storage 11.

If the user accidentally erases or improperly corrects the file while using the customer terminal 13, the customer can select the file restore menu 53 in the program window 50 and restore the file to the previous file.

However, the remote storage file storage and recovery system of this type does not provide a function of returning a file in a previous state according to the user's needs since the file of the final state set by the user is stored in the remote storage 11.

In addition, since the user accesses the storage 11 through the customer terminal 13 and transmits / receives the files, other users attempting to share the same file can not use the system at the same time.

2 is a block diagram illustrating the connection and configuration of a storage system according to an embodiment of the present invention.

The storage system 100 of the present invention is connected to a plurality of user terminals 300 through a network 200 such as the Internet or an internal communication network. The user terminal 300 transmits data created or modified by the user to the storage system 100 and stores the data.

The user can use the service by installing a dedicated program after joining the member from the homepage providing the service of the storage system 100. In the case of data storage service, it may be provided free of charge, but it may be charged by the size of the storage space or the use of the restoration function.

The storage system 100 of the present invention implements basic functions provided by a typical network storage system, i.e., data storage and modification, search, and file transfer. Also, the storage system 100 manages data based on a distributed file system so as to perform services based on a Linux server and enable big data expansion. The stored data is encrypted using various methods including the AES256 algorithm, and has a triple backup structure to prevent data loss.

In the case of the user terminal 300, an interface of the storage system 100 is configured to use both Windows, Linux, and Mac OS devices.

The data management unit 102 included in the storage system 100 receives and stores data transmitted from the user terminal 300 and generates information on the name, size, attribute, and storage location of the stored file. In addition, the user can change the name of the stored data or modify the contents of the data according to the user's selection.

The data management unit 102 generates a snapshot of the data at a time point selected by the user. The generated snapshot is stored in the storage system 100, and the contents and structure of the data selected by the user are directly included. The user can invoke the snapshot to restore the data as is.

The data storage 104 is a space for storing various types of data transmitted from the user terminal 300, which is the same configuration as the storage device of ordinary network storage. Since the storage system 100 can be used by a plurality of users, each user is given a data storage 104 of a predetermined capacity. Each data store 104 is used and managed independently.

In the user terminal 300, it is recognized that the data store 104 assigned to the user is the same as a general local storage device (HDD, etc.).

The snapshot storage 106 stores data for the snapshot created by the data management unit 102. [

The program installing unit 108 transmits the snapshot program for using the data storing and restoring service of the present invention to the user terminal 300 to install the snapshot program. The user can access the storage system 100 through the network 200 by executing the snapshot program at his / her user terminal 300. [ It also enables data storage and snapshot creation via a snapshot program.

3 is a conceptual diagram illustrating a process of generating and storing a snapshot file for a stored data file.

The data storage 104 stores the data file 104a transmitted from the user terminal 300. [ The data file 104a shown in FIG. 3 may be a single file or a set of a plurality of files. When the user executes the snapshot creation function, the snapshot program captures the data file 104a in the current state as it is and creates the snapshot file 106-n. The snapshot file 106-n includes the storage state connected to the user. Therefore, the contents of the HDD recognized by the user terminal 300 are stored as the snapshot file 106-n.

The data management unit 102 generates a snapshot file 106-n and stores it in the snapshot repository 106. [ The snapshot repository 106 is also stored with information on the creation date of the snapshot file 106-n. Information about the creation date is displayed to the user, and the user can restore the data to a file of a specific date.

The user information DB 110 stores extension information of a user subscribed to use the service of the present invention.

Next, a process of storing data, creating a snapshot, and restoring data using the storage system 100 having such a configuration will be described.

4 is a flowchart illustrating a snapshot generation process and data restoration process for data.

First, a user accesses the storage system 100 through a homepage or the like to use the data authoring and restoration service of the present invention, and subscribes as a member while inputting user information (S 102)

The program installing unit 108 transmits the snapshot program to the user terminal 300 via the network 200 and installs the snapshot program (S104)

A user performs a general computer operation using the user terminal 300. In order to store data created or modified at this time, the user sets a space in the storage system 100, selects a specific disk drive, and stores data. S106) The data physically stored by the user is present in the data store 104 inside the storage system 100 connected through the network 200, but is recognized as being in the local device (user terminal) Will be.

When a user who has stored data in the storage system 100 wants to store his / her storage state as a snapshot, the snapshot program is executed and then a snapshot is generated by selecting a disk drive to be stored (S 108)

The snapshot program asks you to take a snapshot of the disk drive you have selected. In the explorer included in the MS Windows program, it may be set to execute the "Snapshot" function from the right-click menu displayed. The data management unit 102 generates a snapshot file 106-n for the selected disk drive. (S110) When taking a snapshot, the user can input a title and a description.

The data management unit 102 stores the information (creation date, disk drive name, size, title, description, etc.) of the created snapshot file 106-n and the list together in the snapshot storage 106 (S110) Once the snapshot is taken and saved, the user will be able to continue working on it.

The snapshot repository 106 stores a plurality of snapshot files 106-n. Typically, the snapshot files 106 - 1 are displayed in the order of the first 106 - 2, 106 - 3,... In some cases, you may want to precede the number of the most recently generated file.

The user can use the user terminal 300 to create new data or change existing data. During this operation, it may be necessary to restore the data to a point in time in order to recover the deleted data or to cause the damage of the file. The present invention uses a method of completely returning the contents of the disk drive to a specific point in time by using the snapshot created by the user. That is, instead of reviving a specific file or restoring a certain setting, the entire storage state of the space storing data is returned to a specific point in time.

The user selects a snapshot file 106-n having a storage state to be restored from among the stored snapshot files 106-n and executes a restoration function (S112). When the right button of the mouse is clicked in the explorer program You can also launch the "Restore Data" function from the submenu.

In response to the execution of the snapshot program, the data management unit 102 calls the selected snapshot file 106-n and changes the state stored in the data store 104 to the contents of the selected snapshot file 106-n. (S114) Since the contents of the snapshot file 106-n of the selected date are directly stored in the storage space allocated to the user, the contents of the data recognized by the user terminal 300 are restored to the date selected by the user and displayed. When the restoration process is completed, the contents of the data store 104 assigned to the user are restored to the data storage state at the restoration time, so that data newly created or changed after the restoration time is destroyed, and the data that has been deleted is revived.

5 is a conceptual diagram illustrating a method of sharing data stored in a storage system with a plurality of users.

A plurality of users subscribe to the data storage and restoration service of the present invention. A user who is connected to another user who is subscribed together can share data contents with each other.

A user who intends to share data with another user first selects an HDD in his / her user terminal 300 and then executes a sharing function. This is the same as the normal intranet sharing function. You can also set the user to share, the sharing period, and permissions.

In FIG. 5, a device of a user to share data is referred to as a first user terminal 302, and a device of a user in a friend relationship is referred to as a second user terminal 304 and a third user terminal 306.

If HDD sharing is set, another user can access the storage system 100 to check and use the file contents stored by the user. At this time, the names of the disk drives are determined in the order of the disk drives used by the respective user terminals 300 as shown in FIG.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, As will be understood by those skilled in the art. Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
