The present invention relates to a migration system which performs a copying process between disks while excluding unnecessary files, comprising: an input unit which receives an original disk and a target disk from a user, and detects selection information related to a copying process after excluding unnecessary files in an operating system and data of a computer system; a display unit which displays the selection information detected in the input unit as well as a copy progress; and a migration unit which, when the process of copying after excluding unnecessary files is detected in the input unit, searches for the unnecessary files from the operation system and data in the original disk, excludes the searched unnecessary files, and copies the rest to the target disk. Thus, according to the present invention, a copying process from a large source disk to a small target disk can be supported. Also, when a large capacity of the original disk is occupied, it is possible to perform copying without an extra operation such as moving, deleting, etc. of unnecessary files. Furthermore, copying time can be reduced since unnecessary files in the operating system and data are not copied.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a migration system and method for excluding unnecessary files from operating system and data of a computer system.

The present invention relates to a migration system and method for excluding an unnecessary file from an operating system and data of a computer system. More particularly, the present invention relates to a migration system and method for replicating an operating system and data of a computer system from a source disk to a replication target disk, And more particularly to a migration system and method.

As the storage device technology advances, storage devices that can be used by users are gradually increasing, starting from a HDD (Hard Disk Drive) and being replaced with a SSD (Solid State Disk).

SSD is not only very fast in writing / reading speed, but it is small and light, so its usage is increasing. However, SSD has a disadvantage that it is very expensive compared to HDD.

Even though these shortcomings exist, many people are increasingly purchasing and using small capacity SSDs.

With the development of these storage devices, technologies for transferring the operating system installed on the existing HDD to the SSD without replacing the operating system and data naturally have been developed for replacing the HDD with the SSD which is fast in use, .

However, since these techniques have been developed to replicate the contents of the original disc to the target disc as it is, it is difficult to replicate from a large capacity disc to a small capacity disc.

For example, if 400 GB is used on a 500 GB source disk, migrating the operating system and data of the original disk to the target disk of 250 GB size is not possible due to the shortage of the target disk.

Therefore, in order to replicate the operating system and data, it is inconvenient to transfer unnecessary data from the original disk to another disk, or to select and delete unnecessary data from the original disk individually and then migrate to the target disk.

Korean Patent Laid-Open Publication No. 10-2011-0071785 (entitled " Data Replication Apparatus and Method of Distributed Database System "

It is an object of the present invention to provide a migration system and method for excluding an unnecessary file from an operating system and data of a computer system when replicating from a source disk to a replication target disk.

In order to accomplish the above object, the present invention provides a migration system which excludes unnecessary files from the operating system and data of a computer system, wherein the system removes unnecessary files from the source disk, the replication target disk and the operating system and data of the computer system, An input unit for detecting information; A display unit for displaying selection information and a reproduction process detected by the input unit; And setting a selected unnecessary file as a copy exclusion target file by searching for an unnecessary file in the operating system and data from the original disk when the copy is detected after excluding unnecessary files in the input unit, And a migration unit for copying only the information to the copy target disk, changing the size of the file to 0 bytes, copying the file to the copy target disk, and deleting the copied file from the copy target disk.

The migration unit may copy the contents of the original disc to the copy target disc if the copy is not inputted after excluding unnecessary files from the input unit.

In addition, the migration unit according to the present invention is characterized in that when the duplication is inputted after exclusion of unnecessary files, the migration unit searches the original disk for a file to be excluded from replication according to a preset search condition of an unnecessary file, and outputs the search result through a display unit .

In addition, the present invention confirms whether the file to be excluded from replication according to the search condition of the unnecessary file is a file having a file size of not less than or equal to a certain capacity, a file having a specific extension, or a file stored in an arbitrary storage location, The size of the file, the file extension, and the storage location of the file can be changed according to the user.

In addition, the migration unit of the present invention changes the size of a file to be cloned to 0 byte, replaces the sector in which the content of the excluded file is located, and replicates it to the clone disk, And deletes the changed copy exclusion target file.

Also, the present invention provides a migration system method for excluding an unnecessary file from an operating system and data of a computer system, the method comprising the steps of: a) detecting copying progress selection information after exclusion of a copy target disk and an unnecessary file through a migration unit input unit; b) determining whether copying is to be performed after excluding a copy target disk and unnecessary files in step a); And c) if it is a copy after excluding unnecessary files as a result of the determination in the step b), the migration unit searches for an unnecessary file in accordance with a search condition of an unnecessary file set in advance on the original disk and extracts an unnecessary file, Copying the operating system and data of the original disk to the duplication target disk as it is if the duplication is not inputted after the unnecessary file is excluded; The step of cloning to the duplication target disk includes the steps of (c-1) retrieving an unnecessary file from the original disc; c-2) creating and displaying a copy-exclusion file list from the searched unnecessary files, and detecting a copy-exclusion file selected by the user through the input unit; c-3) copying only the MFT (Master File Table) information of the selected file to be copied to the copy target disk, changing the size of the corresponding file to 0 byte, and copying the file to the copy target disk; And c-4) deleting the selected copy exclusion file from the copy target disk when the copying to the copy target disk is completed.

Also, the step of searching unnecessary files in the step (c-1) according to the present invention is characterized by searching according to the capacity of the file, the extension of the file, and the storage location of the file.

According to another aspect of the present invention, there is provided a method of searching for a file, the method comprising: checking capacity information of an arbitrary file; Comparing the determined capacity information with the size information of a file to be duplicated excluding, to determine whether the file is a copy exclusion target file; And registering, in the copy excluded file list, if the file is a copy exclusion target file as a result of the determination.

In addition, the step of searching according to the extension of the file according to the present invention includes: checking extension information for a certain file; Comparing the identified extension information with at least one or more predetermined file extension information of copy exclusion target to determine whether the file is a copy exclusion target file; And registering, in the copy excluded file list, if the file is a copy exclusion target file as a result of the determination.

According to another aspect of the present invention, there is provided a method of searching for a file, the method comprising: identifying storage location information for a file; Comparing the verified storage location information with at least one or more preset storage location information to determine whether the file is a copy exclusion target file; And registering, in the copy excluded file list, if the file is a copy exclusion target file as a result of the determination.

1 is a block diagram illustrating a configuration of a migration system that excludes unnecessary files from an operating system and data of a computer system according to the present invention.

1, the migration system 100 includes an input unit 110, a display unit 120, a migration unit 130, a source disk 140, and a replication target disk 150 And may be included and configured in a computer system.

The input unit 110 may include a source disk 140 and a replication target disk 150, and various input means such as a keyboard and a mouse for detecting replication progress selection information after excluding an unnecessary file.

The display unit 120 may include a selection unit for selecting a disc such as the original disc 140 and the copy target disc 150 detected by the input unit 110, a partition of the copy target disc 150, Selection of a copy-exclusion file, and a copying process from the original disk 140 to the copy target disk 150. The display means includes a display means such as a monitor.

The migration unit 130 searches for an unnecessary file in the original disk 140 and extracts the unnecessary file from the original disk 140 except for the sector where the content of the selected unnecessary file is located, To the duplication target disk 150. In this case,

If the duplication process is not performed after the unnecessary files are excluded from the input unit 110, the migration unit 130 deletes unnecessary files from the original disk 140, It is possible to perform a general copying process of copying the contents to the copying target disk 150 as it is.

The migration unit 130 searches the original disc 140 according to a predetermined search condition of an unnecessary file to detect a copy exclusion target file when copying is performed after exclusion of unnecessary files from the user, The detected copy exclusion target file is converted into a format such as a list, and is output through the display unit 120.

In addition, the migration unit 130 excludes the file selected through the input unit 110 from the copying process by the user with respect to the searched copy exclusion target file, and causes the copying target disk 150 to copy the file.

In addition, the migration unit 130 checks the information of the search target file to search for a predetermined file, such as a file having a file size of at least a certain capacity, a file having a specific extension, a file stored in an arbitrary storage location, Compares with the condition and searches for files to be excluded from replication.

The size of the file, the extension of the file, and the storage location of the file can be changed according to the setting information input by the user through the input unit 110.

In addition, the migration unit 130 may modify the size of the file to be excluded in the copy from the MFT of the corresponding file to 0 byte, copy the file to the copy target disk 150, and delete the copied file from the copy target disk 150 after copying do.

All the files of the original disk 140 are stored without being deleted even after copying the files to be copied-exempted.

The copying target disk 150 has the same storage space, a small storage space or a large storage space as compared with the original disk 140. The copy destination disk 150 includes an operating system and data Is stored.

FIG. 2 is a flowchart illustrating a migration method for excluding an unnecessary file from the operating system and data of the computer system according to the present invention. FIG. 3 is a flowchart illustrating a migration process for excluding an unnecessary file from the operating system and data of the computer system according to FIG. FIG. 4 is a flowchart illustrating a process of searching for and copying a file by capacity in a process of copying excluding unnecessary files according to FIG. 3. FIG. 5 is a flowchart FIG. 6 is a flowchart illustrating a process of searching for a file by extension in the process of duplication except for an unnecessary file according to FIG. 3. FIG. FIG. 7 is a flowchart showing the process of excluding the fire A process of modifying the capacity of the excluded file in the process of copying except for the necessary files in the MFT and processing it as 0 bytes.

The migration process according to the present invention will now be described with reference to FIGS. 1 to 7. The migration unit 130 detects duplication progress selection information after excluding unnecessary files from the replication target disk 150 through the input unit 110 (S100 )do.

That is, in operation S100, a user selects a copy target disk 150 to copy an operating system and data to the source disk 140 and the source disk 140, and the operating system and data to be copied to the copy target disk 150 Information for selecting whether to perform the replication process after exclusion of unnecessary files or to copy the same as the operating system and data stored in the original disk 140 to the replication target disk 150 is detected.

The migration unit 130 determines whether replication is input after excluding unnecessary files to the replication target disk 150 selected in step S100 (S110). If it is determined that replication is to be performed after excluding unnecessary files, The controller 130 searches a file according to a search condition of an unnecessary file set in advance on the original disk 140 to exclude a sector in which a selected unnecessary file is located and then transmits the operating system and data of the original disk 140 to the copy target disk 150 (S120).

If it is determined in step S110 that duplication is not inputted after the unnecessary files are excluded, the operating system and data of the original disk 140 are copied to the duplication target disk 150 in step S121.

In step S120, the migration unit 130 searches for unnecessary files in the source disk 140 (S200) when the replication unit 130 determines that the replication unit 130 removes unnecessary files from the input unit 110. FIG.

The unnecessary files retrieved in step S200 are retrieved according to file capacity, file extension, and file storage location.

The process of searching according to the capacity of the file is performed by checking whether the file has a file size of more than or less than a specific capacity and searching for the information of the arbitrary file to be checked (S300) .

The capacity information confirmed in step S300 is compared with the size information of the predetermined copy exclusion target file to determine whether it is a copy exclusion target file (S310).

If it is determined in step S310 that the copy target file is a copy target file, the target file is registered in the copy excluding file list (step S320).

For example, when searching for a file with a capacity of 1 MB or more and selecting a file to be excluded, a file having a small size, for example, a byte or a KB unit is mostly used in an operating system or a program .

In addition, it is convenient to exclude from the search target item because it is difficult to fill a capacity for making a small-capacity file with a copyable capacity.

In addition, the process of searching according to the extension of the file is performed by dividing the file into specific extensions. The extension information is analyzed by analyzing information of an arbitrary verification target file (S400).

In step S410, the extension information determined in step S400 is compared with at least one file extension information (for example, a video file extension, a sound source file extension) that is set in advance,

If it is determined in step S410 that the copy target file is a copy target file, the target file is registered in the copy excluding file list (step S420).

At this time, the search according to the extension of the file searches for the extension of the video file such as avi, mp4, mkv, mpeg, or the extension of the audio file such as mp3 or wav, Most of the video files or audio files are large.

In addition, since most of the video files and the audio files have almost no files that affect the system, it is easy to secure the necessary capacity in the case of excluding from the copying, and it does not affect the operating system of the copying target disk 150 after the copying The possibility is low.

In addition, when only the extension of the file to be checked is searched and selected, if a file is searched using not only the media extension such as a video file or audio file but also the extension of the data file commonly used by the user, the search for the unnecessary file And selection can be made easily.

The searching process according to the storage location of the file is performed by selecting a location frequently used by a user or a general user and analyzing the information of an arbitrary check target file and confirming the storage location information of the file S500 )do.

The storage position information confirmed in step S500 may be compared with at least one or more preset storage location information (e.g., desktop, internal document, internal video, internal music, internal photos, It is determined whether the file is a file (S510).

If it is determined in step S510 that the copy target file is a copy target file, the target file is registered in the copy excluding file list (step S520).

That is, the search according to the storage location of the file is not likely to install an operating system or a program file in a path having a storage location, for example, a storage location such as My Documents, My Videos, My Music, My Pictures, Therefore, when the storage location is searched for, it is less likely to affect the operating system after copying the file to the duplication target disk 150 by mistakenly selecting the file.

In addition, when the storage location is specified, the search time of the file can be shortened because it is possible to search only the location used by the user except for the system folder having many files.

When the unnecessary file search in step S200 is completed, the migration unit 130 creates a copy-exclusion file list including the unnecessary files found in step S200, displays the copy-exclusion file list on the display unit 120, 110 in step S210.

If the user selects the copy exclusion file in step S210, the migration unit 130 modifies the capacity of the selected copy exclusion file in the MFT to 0 bytes, and copies the copied copy exclusion file to the copy destination disk 150 (S220) .

When the user selects the copy exclusion file from the copy exclusion file list, the migration unit 130 confirms the copy target file in the source disk 140 (S600) (S610) whether the file is a copy-exclusion target file selected from the copy-exclusion file list.

If it is determined in step S610 that the copy target file is a copy target file, the migration unit 130 copies only the MFT (Master File Table) information of the copy target file to the copy target disk 150 (S620) The size of the file is corrected to 0 byte in the MFT of the target disk 150 (S630).

In addition, a sector in which the content of the copy exclusion target file is located is excluded from the entire sector list to be copied from the source disk 140 to the copy destination disk 150 at the time of disk migration.

As a result of the determination in step S610, if the file is a copy target file, copying of the sector and MFT information of the file located in the copy target disk 150 (S621) is performed in the same manner as the file content of the original disk 140. [

The reason for changing the file size from MFT information to 0byte instead of deleting the copy exclusion target file from the MFT is that if the information of the selected file is excluded randomly from the MFT, the integrity of the file system $ Bitmap or $ Secure may cause a problem Thereby increasing the likelihood of errors in the file system.

However, if you change the file size to 0byte in MFT, the problem is not caused by $ Bitmap or $ Secure because the file is not deleted and index information of the file is not lost.

In addition, since the file is copied by modifying the file to 0 byte, the portion where the actual data of the file is stored is not duplicated, and unnecessary sectors are not duplicated.

Therefore, the copying time can be shortened because it takes the same copying capacity and time as not copying the data of the selected file except for copying.

Meanwhile, when the copying to the copying target disk 150 is completed (S230), the migration unit 130 deletes the copying exclusion file from the files copied to the copying target disk 150 (S240).

In step S240, since the file information to be excluded from the files copied to the duplication target disk 150 is not deleted from the MFT but is present as a 0 byte file, the duplication target file is deleted from the duplication target disk 150 .

In addition, since the deletion from the replication target disk 150 is performed through the operating system, the file can be deleted without causing a problem in the file system such as MFT, $ Bitmap or $ Secure.

Therefore, even if the destination disk is smaller than the original disk, it can support the operating system and data migration. If the original disk has a large capacity, it can be replicated without any additional operations such as moving and deleting unnecessary files. The migration of the sector where the sector is located is not performed, and the progress time can be shortened.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that
