Details of the wake-up module 104 will be described in detail below.

In another embodiment, the setting module 102 further includes a plurality of termination conditions 1024, such as: using peripheral devices, CPU usage greater than a specific value, hibernation status, etc., when the state of the electronic device meets any one of the plurality of termination conditions 1024 Or, the termination condition 1024 that meets the selection is used as an instruction to stop waking. In other words, the purpose of the open condition 1022 and the termination condition 1024 is opposite. By turning on the condition 1022 to trigger the wake-up module 1024, the subsequent backup steps are performed. 俟 After the backup is completed, the termination condition 1024 is used to stop the wake-up module 104, The electronic device returns to its original state.

In one embodiment, the client can set the open condition 1022 and the termination condition 1024 on the electronic device embedded with the system 100. In another embodiment, the client can set the embedded condition through the remote host server. The opening condition 1022 and the ending condition 1024 of the electronic device of the system 100 are not limited thereto.

In one embodiment, the detection module 103 is coupled to the setting module 102 and the wake-up module 104. The detection module 103 periodically detects the power state of the electronic device. If the detected state meets the opening condition 1022, One of them will select its open condition 1022 as a subsequent operation instruction; on the contrary, if the detected state meets one of the termination conditions 1024, its termination condition 1024 will be selected As a subsequent operation instruction.

One of the plurality of opening conditions 1022 is selected as an instruction to trigger the wake-up module 104. The purpose of the wake-up module 104 is to start the operation of the electronic device through the wake-up module 104 and facilitate automatic backup. In one embodiment, the wake-up module 104 includes a near-end wake-up 1042 and a remote-end wake-up 1044. As shown in the second figure, the near-end wake-up 1042 is intended to be awakened by a peripheral device (such as a mouse or a keyboard). Purpose, the remote wake-up 1044 is a remote system administrator sending a Magic packet to the electronic device via the network to make the electronic device operate normally.

Referring to the second figure, in one embodiment, the remote wake-up 1044 includes a first wake-up mode 1044a and a second wake-up mode 1044b. In an embodiment, the first wake-up mode 1044a must be issued by a remote server. The electronic device receives the network packet with the instruction and judges the network packet. After confirmation, the electronic device immediately executes the boot process. This first Wake-up mode 1044a is Wake-on-LAN (WoL). In another embodiment, the second wake-up mode 1044b improves the first wake-up mode. The remote server and the electronic device must be loaded with a specific processor and a specific system is embedded. The remote management personnel can control a plurality of networks through the network. For the electronic device and its internal files, the second wake-up mode 1044b is the Intel vPro technology. In the preferred embodiment, the remote wake-up 1044 further includes a third wake-up mode 1044c. Based on the improvements of the first and second wake-up modes 1044a and 1044b, data security is improved. VPro is used as a seed computer, which is further coupled to a plurality of electronic devices. For devices such as desktop computers, notebook computers, or tablet computers, managers set conditions on the seed computer, such as turning on the condition 1022 or terminating the condition 1024. The seed computer wakes up through the network to control multiple electronic devices. In other words, Only one seed computer is needed to control the backup of multiple electronic devices at the same time. Furthermore, different instructions can be performed for different electronic devices.

In one embodiment, the segmentation module 202 is coupled between the wake-up module 104 and the backup module 106. After the power state of the electronic device is awakened, the segmentation module 202 segments the backup data to be large. The file is divided into small files, for example, a multiple of 64K is taken as a unit, but it is not limited to this.

Referring to the third figure, in one embodiment, the backup module 106 is coupled to the segmentation module 202. The backup module 106 has different backup modes according to different wake-up modes. The backup module 106 includes a full backup mode (Copy backup) 1062, differential backup mode (Differential backup) 1064 and incremental backup mode (Incremental backup) 1066. In the preferred embodiment, the full backup mode 1062 is suitable for the first time data backup. It fully backs up all files and even backs up the operating system. If the data file to be backed up is larger than a specific value, such as 512MB, it is divided in parallel. Backup, split large files A number of small files are continually backed up to facilitate subsequent compression and encryption. In another preferred embodiment, the differential backup mode 1064 is based on the full backup mode 1062, and only backs up partially changed files. If it is modified or added, the differential backup mode 1064 may change the name, time, or size of the file. If the initial backup status is different, the differential backup mode 1064 will be executed. In short, the full backup mode 1062 is executed only once, and the differential backup mode 1064 must be based on the full backup data before it can be executed. The differential backup mode 1064 must be executed multiple times. In another embodiment, compared with the previous backup data of the incremental backup type 1066, only the added and / or modified part is backed up. Those who are familiar with this technical field should understand that the full backup mode 1062, the differential backup mode 1064, and the incremental backup mode 1066 described in the present invention are not limited to the number of times in the above embodiment, and may vary depending on the needs of the client. Changed. In an embodiment, the backup module 106 further includes a daily backup mode (Daily backup) 1068 and a normal backup mode (Normal backup) 1069, as shown in the third figure. Specifically, the differential backup mode 1064 can be subdivided into two modes according to the number of original data files: the first mode is suitable for a large file and only backs up some differences in the large file, such as Outlook backup (.PST file); the second The mode is applicable to many files. Only some differences among the many files are backed up, and the unchanged ones do not participate in the backup.

The present invention can adopt different wake-up modes and backup modes according to the use timing of the user terminal, and can also be divided into: day-wake backup mode and night-wake backup mode. The biggest difference between the two lies in the different wake-up modes. Generally speaking, the client mostly operates the computer during the day. Therefore, the day wake-up backup mode is required. The detection module 103 detects the power state of the client computer and corresponds to / selects the startup condition 1022 to trigger the wake-up of the module 104. The near-end wakes up 1042 and the backup module 106. For example, if the client computer is in the operation of the screen saver, the system 100 will choose to meet the screen saver's opening conditions, generate relevant instructions, and trigger the backup module 106 to start operation. The backup module 106 will first determine whether For the first full backup, one of full backup or differential backup must be selected according to the file size. At night, the computer is mostly in the shutdown or hibernation state. At this time, the night wake-up backup mode must be used. The detection module 103 detects the client computer status. For example, the hibernation or shutdown is selected to select the on condition 1022 to trigger the wake module 104. The wake-up module 104 sends a wake-up packet to the client computer. The wake-up mode used is determined based on the actual circuit configuration status. After the client computer receives the wake-up packet, the remote wake-up 1044 of the wake-up module 104 will be triggered. To trigger the backup module 106, one of full backup 1062 or differential backup 1064 may be selected according to the file capacity. After the backup is completed, the termination condition 1024 stops the wake-up module 104, and its subsequent backup module 106 will also terminate. The client computer returns to its original state. In the preferred embodiment, the day wake-up backup mode and the night wake-up backup mode are used alternately.

The compression module 108 and the encryption module 110 are commonly coupled to the backup module 106. The compression module 108 and the encryption module 110 may be executed simultaneously or sequentially. In one embodiment, the compression module 108 and the encryption module 110 may be integrated into a compression encryption module, which compresses and encrypts unsegmented data and segmented data into ciphertext data. In one embodiment, the compression module 108 includes a plurality of transformation matrices. Through the non-destructive specific encoding mechanism, the purpose of reducing the size of the file is achieved. In this embodiment, existing compression software such as ZIP, 7z may be used. Or RAR, but not limited to this. The encryption module 110 is encrypted by an encryption algorithm (for example: AES, Advanced Encryption Standard, DES, 3DES, Blowfish). Taking the AES high-level encryption standard as an example, it is not limited to the AES high-level encryption standard, and its key length Formats are 128bits, 192bits, 256bits, and use transparent encryption and decryption. Those who are familiar with this technical field should understand that the compression module 108 and encryption module 110 described above can be implemented in the prior art, so the principle will not be repeated here.

In one embodiment, the system 100 includes a memory unit 114, and in another embodiment, the memory unit 114 is coupled to the system 100. The memory unit 114 is used to store all data and data, including instructions, conditions, backup data, and non-backup data. The memory unit 114 includes a volatile memory and a non-volatile memory (NVRAM). The volatile memory may include a random access memory (Random Access Memory, RAM), and a dynamic random access memory. Take memory (Dynamic Random Access Memory, DRAM), Static Random Access Memory (SRAM), or the like, but not limited to this; non-volatile memory may include read-only memory ( Read-only memory (ROM), Programmable read-only memory, Electronically alterable read-only memory (EAROM), Erasable programmable read-only memory (programmable read only memory (EPROM)), electronic erasable programmable read only memory (EEPROM), flash memory (Flash memory) or the like, but not limited to this. The present invention selects the required memory type and quantity according to actual needs. In the preferred embodiment, the memory unit 114 includes a dynamic random access memory and two flash memories, but is not limited thereto.

In an embodiment, the system 100 further provides a user interface UI (not shown in the figure), which is provided with a switch for automatically switching between day wakeup backup and night wakeup backup, and a wakeup module 104 and a backup module Image 106.

Refer to the fourth figure, which is a flowchart showing the steps of implementing the automatic schedule backup according to the embodiment of the present invention. The process described in this article provides examples of different steps. Although revealing a particular order and sequence, unless If you specify otherwise, you can change the sequence of steps. Therefore, the process described is only exemplary, and the process may be performed by different sequential steps, and even some steps may be performed in parallel at the same time. In addition, not every execution includes the same steps, so the embodiments described herein may omit one or more steps. The invention also includes other steps. The method 300 is implemented by the above-mentioned system 100. The following description mainly uses the system 100 to operate the following steps. If necessary, it may be performed with other conventional steps and components. The method 300 is not limited to be implemented by the same electronic computing device. In the steps, different electronic computing devices must be configured according to actual needs to implement the steps.

Step 301: The client sets the opening condition 1022 and the termination condition 1024 of the electronic device. In an embodiment, the setting module 102 includes a plurality of on conditions 1022 and a termination condition 1024. The on condition 1022 includes that the electronic device is in a low power state (ie, the Sleep state), and the CPU usage is less than a specific value (screen saver). Program is running), electronic device power saving mode, etc. Termination conditions 1024 include the use of peripheral devices, CPU usage greater than a certain value, hibernation status, and the like. In other words, the purpose of the open condition 1022 and the termination condition 1024 is opposite. By turning on the condition 1022 to trigger the wake-up module 1024, the subsequent backup steps are performed. 俟 After the backup is completed, the termination condition 1024 is used to stop the wake-up module 104 and make The electronic device returns to its original state.

Step 302: Detect and confirm the initial state of an electronic device. The operating time of the electronic device is the same as the working time of the client. It works at sunrise and sunset. Generally speaking, the electronic device ’s daytime operation is greater than the nighttime operation. The electronic device ’s daytime status is that the CPU usage is greater than a specific value. The night state includes power saving modes such as hibernation (ie, standby) or off state. In the embodiment of the day state, the detection module 103 detects the state of the electronic device. When the electronic device is in the following states: the screen saver is turned on, the CPU usage is lower than a certain value, etc., it corresponds to the opening of the setting module 102 Condition 1022. In the embodiment of the night state, the remote server may automatically confirm that the electronic device is in a sleep state or a shutdown state.

Step 304: The detected initial state corresponds to one of the opening conditions 1022 of the setting module 102. In the embodiment of the daytime state described above, when the initial state of the electronic device is one of turning on the screen saver, the CPU usage rate being lower than a certain value, etc., it is regarded as an instruction to set the turning-on condition 1022 in the module 102. Similarly, in the above-mentioned embodiment of the night state, when the initial state of the electronic device is sleep or shutdown, it is regarded as an instruction to set the open condition 1022 in the module 102.

Step 306: The enabling condition 1022 triggers the wake-up module 102. It should be noted that this step 306 is optional in the above-mentioned daytime state embodiment. In the above night embodiment, the detection module 103 After confirming the initial state of the electronic device and selecting the startup condition 1022, the selected startup condition 1022 triggers the wake-up module 104. The wake-up module 104 includes a local wake-up 1042 and a remote wake-up 1044. The remote wake-up 1044 is a remote The end system administrator sends Magic packets to the electronic device via the network, so that the electronic device can work normally.

Referring to the second figure, in one embodiment, the remote wake-up 1044 includes a first wake-up mode 1044a and a second wake-up mode 1044b. In an embodiment, the first wake-up mode 1044a must be issued by a remote server. The electronic device receives the network packet with the instruction and judges the network packet. After confirmation, the electronic device immediately executes the boot process. This first Wake-up mode 1044a is Wake-on-LAN (WoL). In another embodiment, the second wake-up mode 1044b improves the first wake-up mode. The remote server and the electronic device must be loaded with a specific processor and a specific system is embedded. The remote management personnel can control a plurality of networks through the network. For the electronic device and its internal files, the second wake-up mode 1044b is the Intel vPro technology. In the preferred embodiment, the remote wake-up 1044 further includes a third wake-up mode 1044c. Based on the improvements of the first and second wake-up modes 1044a and 1044b, data security is improved. VPro is used as a seed computer, which is further coupled to a plurality of electronic devices. For devices such as desktop computers, notebook computers, or tablet computers, managers set conditions on the seed computer, such as turning on the condition 1022 or terminating the condition 1024. The seed computer wakes up through the network to control multiple electronic devices. In other words, Only one seed computer is needed to control the backup of multiple electronic devices at the same time. Furthermore, different instructions can be performed for different electronic devices.

Step 307: Perform data segmentation. The segmentation module 202 is coupled between the wake-up module 104 and the backup module 106. After the power state of the electronic device is awakened, the segmentation module 202 segments the desired backup data and divides the large files into small files. For example: 64K as a unit, but not limited to this.

Step 308: Perform a backup. After the backup module 106 receives the command to wake up the module 104, it starts to execute the backup data file. The backup module 106 includes a full backup mode 1062 and a differential backup mode 1064. In the preferred embodiment, the full backup mode 1062 is suitable for the first time data backup, which comprehensively backs up all documents. If the data file to be backed up is larger than a specific value, the backup is divided in parallel to divide the large file into several pieces. The small files are continually backed up to facilitate subsequent compression and encryption. In another preferred embodiment, the differential backup mode 1064 is based on the full backup mode 1062, and only backs up partially changed files. The differential backup mode 1064 may change the name, time, or size of the file according to the file. , Will execute differential backup mode 1064. In short, the full backup mode 1062 is only executed once, and the differential backup mode 1064 must be based on the previous backup data before it can be executed. Differential backup mode 1064 has to be executed multiple times. Those skilled in the art who are familiar with this technical field should understand that the full backup mode 1062 and the differential backup mode 1064 described in the present invention are not limited to the number of times in the above embodiment, and may be changed according to the needs of the client.

Step 307 and step 308 may be performed in parallel at the same time, or they may be executed independently without any sequence restrictions. Step 307 may occur after step 308, that is, backup first and then partition.

Step 310: compress or / and encrypt the backup data. This step is optional. The compression step and the encryption step must be performed in parallel, or they can be performed independently, but there is no restriction on the sequence. The backup data completed in step 307 or 308 is compressed into a ciphertext fragment by the compression module 108 and the encryption module 110. The backup data and ciphertext data described in this article can be stored in the memory unit 114 of the original electronic device. It can be sent to a remote server or a combination of the two through the network to achieve the effect of synchronization.

Step 311: Perform an integration step to integrate the plurality of ciphertext fragments into ciphertext data. This step is optional and depends on whether the data segmentation of step 307 is performed in advance. The plurality of fragments divided in step 307 and the compressed encrypted encrypted fragments completed in step 308 can be integrated into ciphertext data by an integration module (not shown in the figure), which is stored in the original electronic device. The memory unit 114 may also be transmitted to a remote server through the network, or a combination of the two. In one embodiment, this integration step may be implemented by the compression module 108, and the integration step (step 311) and the compression encryption step (step 310) may be performed in parallel.

Step 312: The termination condition 1024 terminates the wake-up module 104. In one embodiment, after the backup is completed, the termination condition is suspended or / and the wake-up module 104 is stopped, so that the electronic device returns to the initial state. In another embodiment, the termination condition 1024 includes the operation of a peripheral device (such as a mouse or a keyboard). When the client uses the peripheral device during the backup process, the termination condition 1024 will stop or / and suspend the backup module 106 and wake up. The module 104 returns the electronic device to the initial state.

In another preferred embodiment, the present invention may adopt different wake-up modes and backup modes according to the use timing of the client. It can also be divided into: day wake-up backup mode and night wake-up backup mode. The biggest difference between the two lies in the different wake-up methods. Refer to the fifth chart A and the fifth chart B. The fifth chart A shows a flowchart of the steps in the daytime wake-up backup mode, and the fifth chart B shows the flowchart of the steps in the nighttime wake-up backup mode. Refer to Figure 5A. Generally speaking, more clients operate the computer than during the day. Based on this, the day wake-up backup mode must be used. The detection module 103 detects the power state of the client computer and corresponds to / selects the startup condition 1022. The near-end wake-up 1042 of the wake-up module 104 is triggered, so that the electronic device is turned on. Then, the backup module 106 first determines whether a first full backup is required. If the first full backup is not required, The backup person must perform differential backup or incremental backup. For example, if the client computer is in the operation of the screen saver, the system 100 will choose to meet the screen saver's opening condition 1022, generate relevant instructions, and trigger the backup module 106 to start the operation, and the backup module 106 may be based on the file capacity. The size is either one of full backup 1062 or differential backup 1064. Refer to Figure 5B. At night, the computer is mostly shut down or hibernation. At this time, the night wake-up mode must be adopted. The detection module 103 detects the client computer status, such as hibernation or shutdown, to correspond to / select to turn on. Condition 1022, the wake-up module 104 is triggered, so that the wake-up module 104 transmits a wake-up packet to the client computer. The wake-up mode used is determined according to the actual circuit configuration state. The client-side computer triggers the wake-up module 104 after receiving the wake-up packet. The remote wake-up 1044 enables the electronic device to be turned on. Then, the backup module 106 is triggered. It will first determine whether it is necessary to perform the first full backup. If it is not necessary to perform the first full backup, it is necessary to perform a differential backup or increase. Volume backup, etc., the backup module 106 may also select one of the full backup 1062 or the differential backup 1064 according to the size of the file. After the backup is completed, the termination condition 1024 stops the wake-up module 104, and its subsequent backup module 106 will also terminate. The client computer returns to its original state. In the preferred embodiment, the day wake-up backup mode and the night wake-up backup mode are used alternately.

The electronic devices described in this article include desktop computers, notebook computers, tablet computers and other computers with network transmission, but not limited to this. The present invention is not limited to being implemented by the same electronic device. The present invention may be implemented by a plurality of electronic devices. Further, the present invention may be implemented by electronic devices of different operating systems. The operating system includes IOS, Windows, Android, etc. Not limited to this.
