Description

A Fast Copy Device For Storage Device And A Fast Copy Method Using The Same}

The present invention relates to a copying device and a copying method for copying data stored in one original storage device to a plurality of storage devices at the same time, in particular, to enable high-speed copying regardless of the limitations of the operating system, data type, and number of partitions. In addition, the present invention relates to a high speed copying device and a high speed copying device for minimizing an update or upgrade of a copying device according to a change of an operating system or a file system to easily perform multiple copies at a low cost.

A device such as a hard disk drive (hereinafter referred to as a "hard disk") copying device is a device that simultaneously copies one source hard disk to a plurality of target hard disks. Such a copying apparatus is mainly used when a large amount of target hard disk having the same data is needed.

This conventional copying apparatus is performed in the same manner as copying between two hard disks installed in a general personal computer (hereinafter referred to as "PC"). That is, the process of repeatedly reading a predetermined amount of data of the source hard disk and writing the read data to the target hard disk is repeated. The only difference is that in case of PC, the data of the source hard disk is copied to one target hard disk, while the copying device simultaneously copies to the plurality of target hard disks. It is a point of connection.

Multiple copying through such a copying device has many problems. This problem is mainly caused by a limitation by an operating system (hereinafter referred to as "OS").

Specifically, a conventional copying apparatus performs copying by an OS, that is, multiple copying in almost the same way as a PC. Therefore, the conventional copying apparatus is composed of an applied OS and a device corresponding thereto, and as a result, there is a limit to copying only data having a file system of a type supported by the OS. That is, when the data of the source hard disk is in the form of a file allocation table file system (FAT) of Windows, the copying device may be copied only when a system and a supporting program supporting the FAT file system are installed. In particular, the limitations caused by the OS have a problem in that a copy is impossible or impossible depending on the capacity, partition, and type of the hard disk. Moreover, even if the same type of OS is used, the copy device must have the same OS as the source hard disk or a higher OS must be installed in order to perform multiple copies, and the OS of the copy device is lower than the OS of the source hard disk. Or, if the specification before the improvement, there was a problem that it is impossible to copy the data of the source hard disk to the target hard disk.

Moreover, this problem is being highlighted by the use of various operating systems such as Macintosh OS, Windows, Windows NT, and Linux, and the existence of various file systems as each OS family proposes a new improved version.

In addition, recent hard disks have been released with a large number of large products ranging from hundreds of megabytes to hundreds of gigabytes, even terabytes. . However, the copying speed of the conventional copying apparatus is limited by the data transfer capability supported by the OS, and therefore, there is a problem that the high-speed copying is performed only when using an OS that supports a high-speed data transfer and a high-speed data processing function.

Therefore, a company operating a copying device is excessively expensive by purchasing a new copying device or performing a major upgrade every time a new OS or a new file system is developed.

Accordingly, an object of the present invention is to enable high-speed copying regardless of the limitations of the operating system, data types, and the number of partitions, and to minimize the update or upgrade of the copying device according to the change of the operating system or the file system, thereby reducing the cost.

It is determined whether the data storage information exists in the source storage device. If the data storage information written before the data does not exist, the data storage information is created by scanning the source storage device. Store in an empty space of the source storage device; It is created and stored in accordance with the data storage information or newly created storage the data information and copy data from the source storage device at the same time to the plurality of target storage devices.

Discriminate, and if the data is written in the sector as a result of the determination, register the cluster in the data storage information; and if the data described in the sector does not exist, determine whether another sector exists in the same cluster. If the sector to be searched does not exist in the same cluster or if the cluster is registered in the data storage information, it is determined whether there is a residual cluster to be searched in the source storage device. If present, the section Performing re the process of the selection process and later, when the search is the other clusters exist necessary, it carries out re the process of the cluster selection process and later.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. In the accompanying drawings, the same reference numerals are used in the drawings to designate the same configurations in other drawings as much as possible. In describing the present invention, when it is determined that a detailed description of a related known function or known configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, certain features set forth in the drawings are enlarged, reduced, or simplified for ease of description, and the drawings and their components are not necessarily drawn to scale. However, those skilled in the art will readily understand these details.

1 is a configuration example showing a configuration of a high speed copying apparatus according to the present invention.

Referring to FIG. 1, one source storage device 10 and a plurality of target storage devices 90 according to the present invention may be relayed to simultaneously transmit data of the source storage device 10 to a plurality of target storage devices ( To 90).

To this end, the high speed copying apparatus 100 of the present invention is configured to be connected to the source storage device 10 and the plurality of target storage device (90). Here, the source storage device 10 and the target storage device include a hard disk (HDD), an optical disk (CD), a memory card, and an equivalent device thereof. In addition, the high speed copying apparatus 100 of the present invention may perform data copying between storage devices of different types as well as copying data between storage devices of the same type.

The high speed copying apparatus 100 of the present invention reads the data recorded in the source storage device 10 and copies them to the plurality of target storage devices 90 at the same time. In particular, in order to perform such a copy easily and quickly, the fast copy device 100 of the present invention scans data of the source storage device 10 when the source storage device 10 for copying is connected. Check the storage location and create data storage information (da_si) according to the confirmed result. The data storage information da_si copies the data of the source storage device 10 to the target storage device 90.

The data storage information da_si is generated by the high speed copying apparatus 100 and is performed for the source storage 10 connected to the high speed copying apparatus 100 for the first time. Here, in the case of the device where the change of data has occurred, it is preferable to regard the same as the first connection. The data storage information da_si describes in which area of the storage device the data is recorded, and the high speed copying device 100 scans the entire storage area of the source storage device 10 and creates the source storage device. It is recorded and used in the device 10. At this time, the data whose position is recorded in the data storage information da_si, that is, the data copied to the target storage device is all data except the data storage information da_si among the data stored in the data storage area of the source storage device 10. means (data). In other words, the high speed copying apparatus 100 of the present invention copies all the information recorded in the source storage device 10 to the target storage device 90, and the data that the high speed copying device 100 can recognize. If it is, it may be in any form. The reason why such a copy can be performed is based on data storage information (da_si). Conventionally, the file system of the source storage device 10 and the storage system according thereto are used, whereas in the present invention, the high speed copy device 100 is directly used. It is possible by collecting and copying data using the created information.

In order to create the data storage information da_si, the high speed copying apparatus 100 of the present invention divides the storage area of the source storage apparatus 10 into a plurality of zones, for example, a cluster clu set by a user. Here, the cluster clu may be a minimum unit of logical storage, which is generally used, or may be a concept such as a plurality of sectors, tracks, and cells arbitrarily set by a user. For example, when the storage devices 10 and 90 are hard disks, a plurality of sectors may be defined as one cluster clu. The cluster clu may be set differently for each source storage device 10 by the high speed copying device 100, may be generally applied, and may be provided as a setting item by a user. When the cluster clu is defined as described above, the high-speed copying apparatus 100 sequentially checks whether data exists in each cluster region, and scans the entire storage region of the source storage apparatus 10. . According to the scan result, the high speed copy apparatus 100 stores the data storage information da_si and records the data storage information da_si in the source storage device 10, and uses the stored data storage information da_si for subsequent copying. . In addition, when the data storage information da_si exists, the high-speed copying apparatus 100 targets only the cluster clu and the data that are recorded as data by the data storage information da_si. Multiple copying is performed by copying to the same area of the storage device 90. The present invention will be described in more detail with reference to the following drawings and methods.

FIG. 2 is a flowchart illustrating a process of performing high-speed copying by the high speed copying apparatus of FIG. 1, and FIG. 3 is a flowchart specifically showing a data storage information creating step of FIG. 2.

2 and 3, the high-speed copying method according to the present invention is a storage device connection step (S100), data storage information search step (S200), data storage information creation step (S400), data storage information storage step (S500) And a copying step (S600).

In the storage device connection step S100, the source storage device 10 and the target storage device 90 for copying are connected to the high speed copying device 100, and the high speed copying device 100 recognizes this.

The data storage information retrieval step (S200) is a step of searching whether the data storage information da_si previously stored in the source storage device 10 among the storage devices 10 and 90 to which the high speed copying device 100 is connected is present. Since the high speed copying device 100 is a device for copying the plurality of target storage devices 90 by one source storage device 10, the source storage device 10 may be replaced or reused as necessary. In this case, previously stored data storage information da_si may exist when the previously used source storage device 10 is recombined. As such, if the previously created data storage information (da_si) exists, rescanning is unnecessary. Therefore, the data storage information (da_si) can be determined and the high-speed copying can be performed immediately by the existing data storage information (da_si). Can be. Therefore, the high speed copying apparatus 100 searches for the data storage information in the storage area of the source storage device 10 through the data storage information retrieval step S200. Here, the data storage information da_si is mainly stored at the end of the storage area having a relatively low use frequency and a large amount of free space among the storage areas of the source storage device 10, so that the high speed copy device 100 First, it searches for storage. In addition, the end portion of the storage area may be defined as the area that is filled most lately when storing data in the storage system, and the data storage information (da_si) is mainly stored in a relatively low use area or an empty space. do. If the search result data storage information da_si exists, the process branches to the copying step S600 through the determination step S300, and when the data storage information da_si does not exist, the data storage information da_si is created. The copying step (S600) proceeds through.

Data storage information creation step (S400) is performed when the previously stored data storage information (da_si) does not exist in the source storage device 10, the storage device scan and data storage information for the creation of the data storage information (da_si) This is the stage where the creation of. This data storage information creation step (S400) in more detail as shown in Figure 3, as can be seen through this data storage information creation step (S400) is a cluster setting step (S410), cluster selection step (S420), sector It may include a search step (S430), the presence or absence determination step (S440), the data storage information writing step (S445), the next sector presence determination step (S450) and the next cluster UMU determination step (S460).

Cluster setting step (S410) is a step for setting the cluster (clu) for the copy and the creation of data storage information (da_si). Although it will be described in detail later through a separate drawing, the high-speed copying apparatus 100 of the present invention performs cluster-based data determination and cluster-by-cluster copying. Therefore, the cluster may be defined as a logical minimum unit of data storage, which is a conventional cluster concept. However, in the present invention, the cluster is defined as a relatively large data storage block including several sectors. It is preferable. Here, a sector may be defined as a minimum unit that can be addressed by a file system in a general hard disk, and in the present invention, the sector may be considered to refer to a group or a data unit having a specific size. A detailed description thereof will be given later. In the cluster setting step S410, the high speed copy apparatus 100 sets the cluster clu to create data storage information da_si of the source storage device 10 in which the data storage information da_si does not exist. Here, in the description of the present invention, the minimum unit of data storage is regarded as a sector, and the detailed description will be made based on the example in which several to several thousand sectors are regarded as one cluster. Let's proceed. As such, when the size of the cluster clu is set, the storage area of the source storage device 10 is divided into a plurality of clusters clu.

The cluster selection step S420 is a step of selecting an object for determining whether data is written or not, which is basic information recorded in the data storage information da_si. In this cluster selection step (S420), the target cluster clu is selected in order to proceed with a process of determining whether or not data described in the cluster clu exists. The cluster selection step S420 selects all the clusters clu set in the cluster setting step S410 once and sequentially selects all the clusters clu to proceed to the subsequent process. To this end, in the cluster selection step S420, a process of sequentially selecting the plurality of clusters clu set in the cluster setting step S410 is performed one by one, and this selection may be performed by an arbitrary criterion. Here, an arbitrary criterion is a criterion for selecting a cluster order from 100 to 100 in a cluster order, that is, when there are 100 clusters, or selecting from an area having many data descriptions, and set by a user. This can be done. In general, if there is no separate setting, the process proceeds sequentially from the first cluster clu to the last cluster clu.

The sector retrieval step S430 is a step of detecting data described in units of sectors constituting the cluster clu in order to check whether data described in the selected cluster clu exists. Each of the clusters clu set as described above may include a plurality of sectors in which data is described. Although all of these sectors can be described as data, when the data size is small, data may be recorded only in some or any one of the sectors constituting the cluster clu. Therefore, whether or not data is described in the cluster clu is made possible by checking these sectors one by one. In the sector search step S430, a plurality of sectors constituting the cluster clu are sequentially identified one by one to search for sectors in which data is described. This process is repeatedly performed until the threshold condition is reached through the data presence determination step S440 and the data storage information writing step S445.

The data presence determination step (S440) is a step of determining whether data is written in the target sector in the sector search step (S430) and determining the next process accordingly. If data is not described in the sector searched in the aforementioned sector search step (S430), the process branches to the next sector presence determination step (S450) in which there is a remaining sector in the same cluster (clu). If data is described in the sector on which the search has been performed, the process branches to the data storage information da_si writing step S445.

The data storage information writing step S445 is performed when data is written in the search target sector in the data presence determining step S440. The data storage information writing step S445 registers a cluster clu including the sector in the data storage information da_si. Step. It has been mentioned above that the high speed copying apparatus 100 of the present invention performs copying on a set cluster basis. That is, when data is described in any of a plurality of sectors belonging to the cluster (clu), the cluster (clu) is designated as the cluster (clu) in which the data is described, and thus becomes a copy target. The cluster clu designated as the copy target is copied to the target cluster 90 as the cluster clu of the source storage device 10 in the copying step S600. Therefore, in the data storage information writing step S445, in order to copy the cluster clu from the actual copy, the cluster clu having the sector where the data is described in the copy destination is registered. At this time, the registration is described in the form of location information of the cluster (clu), the shape of the data storage information (da_si) is determined by the file system of the operating system installed in the high speed copying apparatus (100). In the high-speed copying apparatus 100 and the high-speed copying method of the present invention, when data is described in any one of a plurality of sectors constituting the current cluster (clu), the current cluster (clu) in which the data is written is a cluster (clu). After determining that the data of the remaining sectors is determined, the next cluster search process is performed. Therefore, when the cluster clu in which data is written is registered in the data storage information da_si, the next cluster presence determination step S460 of determining whether a cluster clu to be searched for exists is subsequently executed.

The next sector presence determination step (S450) is performed when data is not described in the search target sector in the data presence determination step (S440), and a search for whether data is written in addition to the search target sector is required for the current cluster (clu). It is a step to judge if there is any sector left. If it is determined that the next sector exists in the same cluster clu, the sector search step S430 is performed to search for the next sector, and the search is performed in the current cluster clu. If it is determined that the required sector does not exist, the next cluster presence determination step (S460) is performed.

The next cluster presence determination step (S460) is performed after the next sector presence determination step (S450) or the data storage information writing step (S445), and the remaining clusters (clu) requiring determination of whether data is written to the source storage device (10). Is a step of determining whether there is. As a result of the determination of the next cluster presence determination step (S460), if there is a residual cluster (clu), the cluster selection step (S420) and subsequent steps are performed through the above-described process, and it is determined that the residual cluster (clu) does not exist. In step S500, the created data storage information is stored.

The data storage information storage step S500 is a step of storing the data storage information da_si created in the data storage information creation step S400 in an empty space of the source storage device 10. Here, the empty space is an area where data is stored relatively little, but may be a logical end of the data storage area, but this does not limit the present invention. Using the data storage information (da-si) stored in the empty space of the source storage device 10, the high speed copying device 100 selects a cluster to copy and proceeds with copying.

In the copying step S600, the high speed copying device 100 copies the data of the source storage device 10 to the target storage device 90 using the data storage information da_si stored in a predetermined area of the source storage device 10. It's a step. The copying performed in the copying step S600 is performed in the cluster unit set in the cluster setting step S410. The high speed copying apparatus 100 selects a cluster clu to be copied based on the information recorded in the data storage information da_si, and selects the selected cluster clu as a source storage device among the storage areas of the target storage device 90. The data is stored in the same form in an area corresponding to the same location as the storage location (10). In addition, in the case of copying the target storage device 90 of several groups, high-speed copying is realized by repeatedly using the data storage information da_si created once. In addition, the high-speed copying apparatus 100 of the present invention performs copying of a designated unit, that is, a cluster unit, according to whether the data is described as described above. Therefore, if the data stored in the source storage device 10 and the source storage device 10 is in a form recognizable by the high speed copying device 100, it is possible to perform a copy of any kind of data, operating system, and each It is possible to perform copying by the maximum speed supported by the apparatus or the maximum speed supported by the high speed copying apparatus 100. Moreover, such high-speed copying provides the advantage that it is performed between different storage devices if the capacity of the target storage device 90 is greater than or equal to that of the source storage device 10.

4A and 4B are diagrams for explaining a high-speed copying method according to the present invention. FIG. 4A is an exemplary diagram for explaining setting of a cluster, and FIG. 4B is an exemplary diagram for explaining a process of creating data storage information. to be.

 4A and 4B, the source storage device 10 has a storage area 11 in which data is stored. In the present invention, such a storage area 11 is divided into a plurality of continuous clusters (clu: clu1 to clu (n)) for high-speed copying.

The cluster clu may be defined as a minimum unit of logical division for data storage as described above, or may be any section defined by a user. The plurality of clusters clu, which divides the storage area 11, may be composed of a plurality of sectors (sec: sec1 to sec (m)). Like a cluster, a sector is defined as a minimum unit that can be addressed in a file management system through a concept used in a computer, or a plurality of bits, bytes, and words defined by a user. word) or a data section of the same type. The division of the cluster (clu) and the sector (sec) is preferably changed according to the capacity of the storage device (10, 90), in the case of a large storage device, the cluster (clu) and sector so as to have a relatively large capacity section (sec), and in the case of a storage device having a small capacity, vice versa may be advantageous for fast copying.

As shown in FIG. 4A, each of the plurality of clusters clu configured by dividing the storage area 11 may include m sectors that are arbitrarily set. Clusters do not have to all have the same number of sectors (sec), but it may be advantageous to have the same number for convenient management and copying.

When the cluster clu is set as described through the above-described high-speed copying method, the data storage information da_si is generated by distinguishing the cluster clu in which data is written and the cluster clu in which the data is not. To this end, the sector search step S430 is performed to search for data entry of the sector sec included in the cluster clu.

For example, in the case of parallel ATA (Parallel AT Attachment) method, using LBA (Local Block Addressing), LBA24 uses 256 sectors of 512 bytes per sector at once. DMA), and in the case of LBA48, 65536 sectors can be transmitted at a time. Therefore, the size of the cluster (clu) is preferably set to have an optimal copy speed in response to this transmission capacity, or as defined above according to the capacity.

The search process for the presence or absence of such data is illustrated in FIG. 4B. In FIG. 4B, for example, three clusters clu1 to clu3 having four sectors sec1 to sec4 are shown as an example. In the foregoing description, it has been mentioned that the search order of the clusters clu may be performed sequentially or may be performed in an order determined by any condition. In FIG. 4B, a sequential search is performed from the first cluster clu1 to the third cluster clu3, and the sectors sec of each cluster clu are also moved from the first sector sec1 to the fourth sector sec4. The description will be made as a sequential process. In addition, in FIG. 4B, portions in which data is described are shaded and displayed. That is, it is assumed that data is described in the third sector sec3 of the second cluster clu2 and the third and fourth sectors sec3 and 4 of the third cluster clu3.

First of all, the first cluster clu1 is selected to determine whether the cluster clu is written. When the first cluster clu1 is selected, the first sector sec1 of the first cluster clu1 is searched to check whether data is described. In FIG. 4B, since no data is described in any sector (sec) of the first cluster (clu1), the high speed copying apparatus (100) searches for the first sector (sec) in accordance with the above-described storage information creating step (S400). After that, the second to third sectors (sec2 to sec4) are sequentially searched. That is, the search starts from the time point A and the search is sequentially performed to the time point B to search the first cluster clu1. In this case, since the sector sec having data is not found in the first cluster clu1, the first cluster clu1 is not described in the data storage information da_si.

Then, since the remaining clusters clu2 and clu3 remain, the search is performed again from the time point B. When the first and second sectors sec1 and 2 are sequentially searched, and then the data described in the third sector sec3 is found, the high-speed copying apparatus 100 stops searching for data in the second cluster clu2. (C time point), the second cluster clu2 is described in the data storage information da_si. Then, the data of the fourth sector sec4, which is the remaining sector of the second cluster clu2, is not searched, and the third cluster clu3 is searched at the time B '. Similarly, since the third cluster clu3 has data written in the third sector sec3, the third cluster clu3 is registered as a cluster clu in which data is written in the data storage information da_si regardless of whether the fourth sector sec4 has data written. Will be.

Thereafter, when copying is performed, the second cluster clu2 and the third cluster clu3 are designated as copy targets, so that a third sector sec3 and a third cluster clu3 of the same shape, that is, the second cluster clu2 are designated. The data is copied to the target storage device in the form of data described in the third and fourth sectors (sec3, 4).

As described above, the data storage information da_si is created according to the file system of the high speed copying device 100 separately from the operating system and the file system of the source storage device 10, and the copying is performed using the data system. do. Therefore, if the data of the source storage device 10 can be recognized by the high speed copying device 100, the data is copied regardless of which operating system or file system is used.
