Description

  The present invention relates to a backup system for creating a backup file of an electronic file.

  With the development and spread of electronic devices such as computers and smartphones in recent years, and further paperlessness in offices and the like, electronic files created by electronic devices (hereinafter abbreviated as files) are increasing. There are various types of files, but all the files are important for the creator and the like, and it is not desirable to lose them. In particular, many files created at business establishments are indispensable for continuing the business, and losing them greatly affects the business.

  However, there is a possibility that the file cannot be read due to a failure of the electronic device itself or a recording medium such as a hard disk drive or a flash memory for recording the file. In recent years, electronic devices may be infected with ransomware that encrypts files or computer viruses that destroy files. In such cases, the files cannot be used.

  One method for dealing with such a case is to create a copy (backup file) of the file. If each user updates a file each time a backup file of the file is created, the above problem can be dealt with. However, this method places a heavy burden on the user and may forget to create a backup file, so the certainty of creating the backup file cannot be guaranteed.

  In order to solve such a problem, a backup system that automatically creates a backup file has been proposed (for example, Patent Document 1). The backup system of Patent Document 1 is composed of a business server, a management PC, and a data center. When the business server occurs every day, the regular full backup data is transferred to the management PC at a specified time. The data transferred from the server is stored, and the data transferred from the business PC is transferred to the data center at a specified time every day, and the data center is configured to store the transferred data.

  However, in the backup system of Patent Document 1, if the file becomes unusable before the time for executing the backup process after the update operation is performed on the file, the file of the updated file is updated. Since the backup file has not been created, the updated file cannot be restored.

  The present invention has been made in view of the above problems, and an object thereof is to provide a backup system that can easily and reliably create a backup file.

  A backup system comprising: a recording device connected to an electronic device for recording the electronic file, and a backup server having a backup recording unit for recording the back file of the electronic file, according to the present invention for solving the above problems In one preferred embodiment of the present invention, a detection device that detects that a predetermined operation has been executed on the electronic file on the recording device, and the detection device has executed the predetermined operation. An upload device that transmits the detected electronic file to the backup server, and the backup server creates a backup file of the electronic file transmitted from the upload unit in the backup recording unit; It is equipped with.

  In this configuration, when a predetermined operation is performed on the electronic file on the recording device, the electronic file becomes a backup target file. Then, the electronic file is transmitted to the backup server, and the backup file is created in the backup server. Thereby, a backup file can be created reliably. In particular, when a predetermined operation is performed on an electronic file, a backup file is created. If a predetermined operation is newly created or updated, a backup file of the electronic file that has been reliably updated can be obtained. Can be created.

  In one preferred embodiment of the backup system according to the present invention, the recording device is a NAS, and the backup server and the NAS are connected by a wide area communication network.

  In this configuration, the backup server can be installed at a remote location different from the location where the NAS is installed. Therefore, when a disaster or the like occurs, the possibility of both being damaged is reduced. In addition, if the external server operates and manages the backup server, NAS users do not need to perform operation management of the backup server, and a backup system is introduced even for small-scale businesses that cannot place system administrators. can do.

  In one preferred embodiment of the backup system according to the present invention, the backup creation unit creates a snapshot of the electronic file in the backup recording unit.

  In this configuration, since the backup creation unit creates a snapshot of the electronic file, the history of the electronic file can be recorded with a small recording capacity. Thereby, an electronic file at an arbitrary time can be restored.

[System Overview]
Embodiments of a backup system according to the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram of a backup system in the present embodiment. As shown in the figure, the backup system according to the present embodiment includes a client terminal 1 (an example of an electronic device according to the present invention), a NAS 2, and a backup server 3. The client terminal 1 and the NAS 2 are connected via a computer network L (hereinafter abbreviated as “network L”), and the NAS 2 and the backup server 3 are connected via a computer network W (hereinafter abbreviated as “network W”). Connected. In the present embodiment, a LAN (Local Area Network) is used as the network L, and the Internet (an example of a wide area communication network in the present invention) is used as the network W.

  Although one client terminal 1 and one NAS 2 are shown in the figure, the number of client terminals 1 and NAS 2 can be changed as appropriate.

[Client terminal]
The client terminal 1 is an electronic device that can be connected to the network L and can generate an electronic file (hereinafter abbreviated as a file). As the client terminal 1, for example, a general-purpose computer, a smartphone, a tablet terminal, or the like can be used, and thus detailed description thereof is omitted.

[NAS]
NAS2 is called Network Attached Storage, and is an auxiliary recording device connected to a computer network. In this embodiment, the client terminal 1 and the NAS 2 are installed in the same office and are connected by the network L configured by the LAN as described above. Therefore, it is possible to copy and refer to files between the client terminal 1 and the NAS 2 and to directly edit files on the NAS 2 from the client terminal 1.

  The NAS 2 includes a recording unit 21, a detection unit 22, an upload unit 23, and a control unit 24. The recording unit 21 includes a hard disk drive or the like, and records and holds a file generated by the client terminal 1. The detection unit 22 is a functional unit that detects that a predetermined file operation in the recording unit 21 has been executed. Here, the predetermined file operation is an operation for changing the contents of the file, for example, new creation, update, or the like. The upload unit 23 is a functional unit that transfers (uploads) an operated file (hereinafter referred to as an operated file) to the backup server 3 when the detection unit 22 detects a predetermined file operation. The control unit 24 is a functional unit that controls various operations of the NAS 2.

  The detection unit 22, the upload unit 23, and the control unit 24 are configured by cooperation of software including NAS2 OS (Operating System) and NAS2 hardware. Each constitutes a detection device and an upload device in the present invention.

[Backup server]
The backup server 3 is a device for recording and holding backup files, and can be configured by, for example, a general-purpose computer. The backup server 3 includes a backup recording unit 31, a backup creation unit 32, and an authentication unit 33. The backup recording unit 31 can be configured by a recording medium such as a large-capacity hard disk drive, and records and holds a backup file. The backup creation unit 32 is a functional unit that creates a copy (backup file) of a file uploaded from the NAS 2 on the backup recording unit 31. The authentication unit 33 is a functional unit that performs user authentication based on authentication data transmitted from the NAS 2. In this embodiment, the backup creation unit 32 and the authentication unit 33 are configured by cooperation of software including the OS of the backup server 3 and hardware of the backup server 3, respectively.

  In this embodiment, the backup server 3 is installed at a remote location different from the installation location of the client terminal 1 and the NAS 2, and as described above, the backup server 3 is connected to the NAS 2 via the network W configured as the Internet. It is configured as a so-called cloud server.

  The processing flow of the backup system in this embodiment will be described below using the flowchart of FIG. Prior to the following processing, a unique user ID and password (hereinafter collectively referred to as authentication data) are set in the NAS 2. When such NAS 2 is connected to the network W, the control unit 24 transmits its own authentication data to the backup server 3 together with its own identification information. On the other hand, the backup server 3 records this information as user data and uses it for NAS2 authentication. At the same time, the backup server 3 allocates a recording area of a predetermined capacity on the backup recording unit 31 to the NAS 2. Note that the NAS2 IP address or MAC address can be used as the NAS2 identification information.

  First, when the NAS 2 is activated, the control unit 24 of the NAS 2 transmits its own authentication data to the backup server 3. On the other hand, the authentication unit 33 of the backup server 3 that has received the authentication data from the NAS 2 collates the recorded user information with the received authentication data (# 01). At this time, if the received authentication data is registered as user information, the authentication is successful (Yes branch of # 01), the NAS 2 is notified of the success of authentication, and the backup processing from the NAS 2 is enabled. On the other hand, when the authentication fails (No branch of # 01), the NAS 2 is notified that the authentication has failed.

  In the NAS 2 that has received the notification that the authentication was successful from the backup server 3, the detection unit 22 determines whether or not a predetermined operation has been performed on the file on the recording unit 21 (# 02). In addition, it is possible to set in advance a target for the detection unit 22 to detect whether or not there is an operation. In the present embodiment, a folder (directory) on the recording unit 21 is set as a detection target. In addition, as described above, the predetermined operation on the file in the present embodiment is a new creation or update of the file. Therefore, the detection unit 22 detects an operation such as creating a new file in the detection target folder or updating a file existing in the monitoring target folder. And if the detection part 22 detects those file operations (Yes branch of # 02), it will notify the control part 24 of that and the information regarding the operated file. The information regarding the file may be information that can identify the operated file. For example, the file name of the full path of the operated file can be used.

  Receiving the notification that the file operation is detected from the detection unit 22, the control unit 24 instructs the upload unit 23 to upload the operated file to the backup server 3. Upon receiving the instruction, the upload unit 23 uploads the operation file to the backup server 3 (# 03).

  On the other hand, in the backup server 3 that has received the uploaded operation file, the backup creation unit 32 creates a copy (backup file) of the uploaded operation file on the backup recording unit 31 (# 04). As described above, since a recording area is allocated to each NAS 2, the backup creation unit 32 specifies a recording area for creating the backup file based on the identification information of the NAS 2 that uploaded the operated file. And create a backup file there.

  When the creation of the file is completed, the backup creation unit 32 notifies the NAS 2 to that effect. In the NAS 2 that has received the notification from the backup creation unit 32, it is assumed that the control unit 24 has completed the backup process for the operated file (# 05).

  As described above, in the backup system according to the present embodiment, the backup process is executed when a predetermined operation is performed on the file on the NAS 2, so that the user does not need to be aware of the backup process. Further, since backup processing is performed when a predetermined operation is performed on the file, timely backup processing can be performed. Further, if the backup server 3 is operated by an external business operator, the NAS 2 user does not need to manage and maintain the backup server 3, so even a small business operator who cannot arrange a system administrator, A backup system can be introduced.

  The backup creation unit 32 may be configured to create a snapshot of the operation file. For example, if a file system for creating a snapshot, such as ZFS or BTRFS (B-TRUE File System), is used for the backup recording unit 31, a snapshot can be easily created. In particular, by configuring the backup creation unit 32 to be able to record snapshots at a plurality of points in time, a file update history can be recorded with a small recording capacity, and a file at any point in time can be restored.

  Although it is conceivable to create a snapshot in the recording unit 21 of the NAS 2, this case is not preferable because the capacity for recording a normal file on the recording unit 21 of the NAS 2 is reduced. Further, since recording of file snapshots increases access to the hard disk drive or the like, the life of the hard disk drive or the like is shortened, which is not preferable. On the other hand, if the configuration is such that a snapshot is created in the backup recording unit 31 of the backup server 3 as in the present embodiment, and the operation of the backup server 3 is an external business operator, the user of the NAS 2 can record the recording capacity and recording. There is no need to worry about the life of the medium.

[Another embodiment]
(1) In the above-described embodiment, the recording apparatus is configured by the NAS 2. However, the present invention is not limited to this, and a recording medium such as a hard disk drive built in or connected to an electronic device can be used as the recording apparatus.

(2) In the above-described embodiment, the monitoring device and the upload device are configured by the NAS 2. However, the present invention is not limited to this, and can be configured by a separate computer terminal or the client terminal 1. Naturally, the definition of the arrangement of the functional units constituting these devices can be changed.

(3) In the above-described embodiment, the file is transmitted to the backup server 3 when a predetermined operation is performed on the file. However, the transmission timing to the backup server 3 is not limited to this. For example, a file that has been subjected to a predetermined operation may be listed, and the file listed at a predetermined time may be uploaded to the backup server 3. With this configuration, for example, if the predetermined time is set to a time zone with little traffic, the influence on business can be reduced.

(4) In the above-described embodiment, the detection unit 22 detects a predetermined operation on the file in real time. However, the detection timing of the predetermined operation is not limited to this. For example, it is possible to detect a predetermined operation by determining whether or not a predetermined operation has been performed on the file at a predetermined time.

  The present invention can be used for a backup system.
