  By the way, the backup program as described above has a restore function for retrieving backup data on the backup server as needed and restoring it on the client computer. This restore function is not only used to selectively restore some backup data, but also to restore all backup data at once (hereinafter referred to as recovery), for example, client computer replacement or hard disk replacement. Also used when

  However, the recovery of the backup data accompanying the replacement of the client computer, etc. is performed after the installation of the client backup program on the client computer, the startup of the client backup program, the access to the backup server, the presence of the backup data, etc. However, the burden on the user is large. In addition, some users may not know the existence of backup data or forget to recover backup data. In this case, the backup data on the backup server is wasted.

The present invention has been created with the object of solving these problems in view of the above circumstances, and is connected to a client computer via a network and a client backup program executed on the client computer. A backup program for backing up data on the client computer on the backup server in accordance with the establishment of the backup start condition, the server backup program being executed on the backup server The first activation determination means for determining whether or not the client computer is activated for the first time, and the client computer in the case of the first activation. Backup data existence confirmation means for confirming whether backup data related to the computer exists in the backup server, and when backup data exists in the backup server, the backup data is received from the backup server, and the backup data is received by the client computer And automatic recovery execution means for restoring to the top. In this way, when the backup data needs to be recovered, for example, when the client computer is replaced or the hard disk is replaced, the client backup program is installed on the client computer and the client backup program is started. By simply doing so, the backup data on the backup server can be restored on the client computer and the recovery can be automatically completed, so the burden on the user can be reduced. In addition, even when the user does not know the presence of backup data, the backup data can be reliably recovered, so that the inconvenience that the backup data on the backup server is wasted can be prevented.
In addition, the automatic recovery execution means performs confirmation of execution of automatic recovery with respect to the user before performing automatic recovery. In this way, execution of automatic recovery against the user's will can be avoided.

  According to the present invention as described above, in a situation where the backup data needs to be recovered, the client backup program is installed on the client computer, and the backup data on the backup server can be restored simply by starting the client backup program. It can be restored on the client computer and the recovery completed automatically.

[Backup system]
Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2, reference numeral 1 denotes a backup system to which a backup program of the present invention is applied. The backup system 1 is connected to a client PC (client computer) 2 and a backup server 3 so that they can communicate with each other. And a network 4 such as a local area network (LAN).

  The client PC 2 is a computer in which the backup program of the present invention (client backup program) is installed. When the client backup program is executed on the client PC 2, predetermined data in the storage area 5 of the client PC 2 is stored. It is possible to back up to the storage area 6 of the backup server 3 connected via the network 4.

  The backup server 3 is a computer in which the backup program (server backup program) of the present invention is installed, and when the server backup program is executed on the backup server 3, the client PC 2 responds to a request from the client PC 2. The backup data can be received and the received backup data can be stored in the storage area 6.

[Backup program]
The backup program of the present invention includes a client backup program executed on the client PC 2 and a server backup program executed on the backup server 3 connected to the client computer 2 via the network 4. As a result of these cooperation, an automatic backup function, a restore function, an automatic recovery function, and the like are realized.

  As shown in FIG. 2A, the automatic backup function automatically backs up the data in the storage area 5 of the client PC 2 to the storage area 6 of the backup server 3 according to the establishment of the backup start condition. It is. For example, it is a time specified by the user (for example, every hour after the system is started), a time specified by the user (for example, 17:00 every day), or a predetermined operation (for example, a system termination operation) by the user. The backup start condition is that the computer is in a non-operating state for a predetermined time (for example, 10 minutes), and the data on the client PC 2 is automatically transferred to the backup server 3 according to the determination of establishment. It becomes possible to back up.

  As shown in FIG. 2B, the restore function is a function for retrieving backup data on the backup server 3 as necessary and restoring it on the client PC 2. Conventionally, this restore function is not only for selectively restoring a part of backup data but also for restoring all backup data at once, for example, when replacing the client PC 2 or replacing the hard disk It was also used for data recovery. However, the recovery of the backup data accompanying the replacement of the client PC 2 is performed after the client backup program is installed on the client PC 2, the client backup program is started, the backup server 3 is accessed, and the existence of the backup data is confirmed. The user had to do it manually.

  As shown in FIG. 2C, the automatic recovery function receives the backup data related to the client PC 2 from the backup server 3 when the client backup program is activated for the first time in the client PC 2, and automatically executes it on the client PC 2. It is a function to restore to. Specifically, when the client PC 2 is activated, an initial activation determining unit that determines whether or not the client PC 2 is activated for the first time, and in the case of the first activation, the backup data related to the client PC 2 is stored in the backup server. Backup data existence confirmation means for checking whether or not the backup data exists in the backup server 3 and automatic backup data is received from the backup server 3 and restored on the client PC 2 when backup data exists in the backup server 3. By providing the recovery execution means, an automatic recovery function is realized. The backup data relating to the client PC 2 is specified based on the setting information (serial number, user name, user ID, etc.) of the client backup program, the computer name of the client PC 2 on the network 4, the IP address, and the like. Can do.

  According to such an automatic recovery function, in a situation where backup data needs to be recovered, for example, when the client PC 2 is replaced or the hard disk is replaced, the client backup program is installed on the client PC 2 and the client By simply starting the backup program, the backup data on the backup server 3 can be restored on the client PC 2 and the recovery can be automatically completed, so the burden on the user can be greatly reduced. In addition, even when the user does not know the presence of backup data, the backup data can be reliably recovered, so that the inconvenience that the backup data on the backup server 3 is wasted is prevented.

  The automatic recovery execution means preferably confirms execution of automatic recovery with respect to the user before performing automatic recovery. For example, as shown in FIG. 3, a dialog box 7 including a confirmation message such as “Do you want to recover a previously backed up file from the backup server?” Is displayed, and a button 7a arranged on the dialog box 7 is displayed. 7b, when the “Yes” button 7a is selected and operated, automatic recovery is executed, whereas when the “No” button 7b is selected and operated, execution of automatic recovery is skipped. In this way, execution of automatic recovery against the user's will can be avoided.

[Backup program processing procedure]
Next, specific processing procedures of the client backup program and the server backup program according to the present invention will be described with reference to FIGS. However, since the automatic backup processing procedure and the restoration processing procedure are not the main part of the present invention, illustration and description of specific processing procedures are omitted.

  As shown in FIG. 4, the client backup program determines whether or not it is the first activation after activation (S11: first activation determination means). If this determination result is NO, a series of automatic recovery processing (S13 to S15: automatic recovery means) is skipped, and automatic backup processing (S16) and restore processing (S17) are repeatedly executed. On the other hand, when it is determined that it is the first activation, it is confirmed whether or not the backup data related to the client PC 2 exists on the backup server 3 (S12: backup data existence confirmation means). If the determination result is NO, the automatic recovery process is skipped, but if the determination result is YES, execution confirmation of automatic recovery is performed for the user (S13, S14). If the user selects “No”, the automatic recovery is skipped, and if “Yes” is selected, the automatic recovery is executed (S15). The automatic recovery is performed by requesting the backup server 3 to transfer the backup data related to the client PC 2, receiving the backup data transferred from the backup server 3, and restoring the received backup data on the client PC 2. Is called.

  As shown in FIG. 5, the server backup program determines a request from the client PC 2 after being started (S21, S24, S27). The request from the client PC 2 includes a backup request, a data transfer request, a backup data existence confirmation request, and the like. When the backup request is determined (S21), the data transmitted from the client PC 2 is received (S22). The received data is stored in the storage area 6 of the backup server 3 (S23). When a data transfer request is determined (S24), backup data is acquired from the storage area 6 (S25), and the acquired backup data is returned to the client PC 2 (S26). If the backup data existence confirmation request is determined (S27), the backup data in the storage area 6 is searched based on the specific information of the client PC 2 (S28), and the search result (presence / absence of existence and data list information). Is returned to the client PC 2 (S29).

[Operation procedure of the entire backup system]
Next, the overall operation of the backup system 1 will be described with reference to FIG. However, FIG. 6 shows the overall operation of the backup system 1 during automatic recovery.

  As shown in FIG. 6, the client backup program confirms whether or not the backup data related to the client PC 2 exists in the backup server 3 when the client PC 2 is activated for the first time (S101). The existence confirmation of the backup data is performed by transmitting a backup data existence confirmation request to the backup server 3 (S102). The backup server 3 that has received the backup data existence confirmation request confirms whether or not the corresponding backup data exists in the storage area 6 (S103). If the backup data exists, the backup data exists in the client PC 2. A reply to that effect is sent (S104). When the backup data exists, the client PC 2 sends a backup data transfer request to the backup server 3 (S105). Receiving this request, the backup server 3 acquires corresponding backup data from the storage area 6 (S106), and transfers it to the client PC 2 (S107). The client PC 2 receives the backup data transferred from the backup server 3, and saves this data in the storage area 5 (S108). Note that the processing of S105 to S109 is repeated until all data restoration is completed (S109).

  According to the present embodiment configured as described, the client backup program executed on the client PC 2 and the server backup program executed on the backup server 3 connected to the client PC 2 via the network 4 And a backup program that backs up data on the client PC 2 on the backup server 3 in response to the establishment of the backup start condition. The client backup program is activated for the first time on the client PC 2 when the client PC 2 is started. And whether or not the backup data related to the client PC 2 exists in the backup server 3 in the case of the first activation, and the backup server Backup data if present, receives the backup data from the backup server 3 includes an automatic recovery function for restoring the backup data on the client PC2 to. Therefore, in a situation where backup data needs to be recovered, for example, when the client PC 2 is replaced or the hard disk is replaced, the client backup program is installed on the client PC 2 and the client backup program is started. Since the backup data on the backup server 3 can be restored on the client PC 2 and the recovery can be automatically completed, the burden on the user can be greatly reduced. In addition, even when the user does not know the existence of backup data, the backup data can be reliably recovered, so that it is possible to prevent inconvenience that the backup data on the backup server 3 is wasted.

  In addition, since the execution confirmation of the automatic recovery is performed with respect to the user before the automatic recovery is performed, it is possible to avoid the execution of the automatic recovery against the user's will.

  Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the claims. Further, in the claims and the present specification, terms such as a client computer, a backup server, a client backup program, and a server backup program are used, and the client included in these terms is a backup process via a network. The server indicates the backup destination of the backup processing via the network, and the concept of the client or server defined by the hardware or OS type, the master-slave relationship in the network setting, etc. is not necessarily It does not match. For example, the present invention includes a case where data on a server in which a client backup program is installed is backed up on a client PC or a second server in which the server backup program is installed.

  In the above embodiment, since backup data history management (generation management) is not performed, the backup data transferred from the backup server to the client computer by the automatic recovery function is necessarily the latest backup data. When performing history management (generation management) of backup data, the user may be able to select the generation of backup data to be transferred before execution of automatic recovery.
