In one embodiment, the system 100 further provides a user interface UI (not shown) having a switch for automatically switching between the daytime wakeup backup and the nighttime wakeup backup, and an image Icon having a wakeup module 104 and a backup module 106.
Referring to FIG. 4, a flowchart illustrating steps for implementing automatic scheduling of backups according to an embodiment of the present invention is shown. The flow described herein provides examples of the different steps. Although a particular order and sequence is disclosed, the order of the steps of the flowchart may be altered unless otherwise specified. Thus, the flows described are exemplary only, and the flows may be performed by different sequential steps, even though some of the steps may be concurrent. In addition, not every execution includes the same steps, so one or more steps may be omitted from the embodiments described herein. The invention also includes other steps. The method 300 is implemented by the system 100, and the following description is mainly performed by the system 100 to operate the following steps, if necessary, with other conventional steps and components, and the method 300 is not limited to the steps implemented by the same electronic computing device, but different electronic computing devices can be configured to implement the step flow according to actual requirements.
Step 301: the client sets the start condition 1022 and the end condition 1024 of the electronic device. In one embodiment, the setting module 102 includes a plurality of start conditions 1022 and end conditions 1024, where the start conditions 1022 include that the electronic device is in a low power consumption state (i.e., a Sleep state), the CPU utilization is less than a specific value (during the operation of the screen saver), and the electronic device is in a power saving mode. The termination conditions 1024 include the use of peripheral devices, CPU usage greater than a specified value, sleep state, etc. In other words, the purpose of the start condition 1022 and the end condition 1024 is opposite, and the wake-up module 1024 is triggered by the start condition 1022 to perform the subsequent backup step; after the backup is completed, the wake-up module 104 is stopped by the end condition 1024, and the electronic device is returned to the original state.
Step 302: detecting and confirming an initial state of an electronic device. Generally speaking, the daytime running amount of the electronic device is greater than the nighttime running amount, the daytime state of the electronic device is that the CPU utilization rate is greater than a specific value, and the nighttime state of the electronic device comprises power saving modes such as a dormant (standby) state or a power-off state. In the daytime state embodiment, the detecting module 103 detects the state of the electronic device when the electronic device is in the following states: if the screen saver is turned on, the CPU utilization is lower than a certain value, and the like, the on condition 1022 of the setting module 102 is corresponded to. In the night state embodiment, the remote server automatically confirms that the electronic device is in the sleep state or the power-off state.
Step 304: the detected initial state corresponds to one of the enabling conditions 1022 of the configuration module 102. In the daytime state embodiment, when the initial state of the electronic device is one of the screen saver being turned on, the CPU utilization being lower than a certain value, etc., it is regarded as an instruction to set the on condition 1022 in the module 102. Similarly, in the night state embodiment, when the initial state of the electronic device is a sleep or power off state, it is regarded as an instruction for setting the on condition 1022 in the module 102.
Step 306: the on condition 1022 triggers the wake-up module 102. It should be noted that this step 306 is optional in the daytime state embodiment described above. In the above night embodiment, after the detection module 103 confirms the initial state of the electronic device and selects the start condition 1022, the selected start condition 1022 triggers the wake-up module 104, the wake-up module 104 includes a near-end wake-up 1042 and a remote wake-up 1044, where the remote wake-up 1044 is a map packet transmitted by a remote administrator to the electronic device through a network, so that the electronic device operates normally.
Referring to fig. 2, in an embodiment, the remote wake-up 1044 includes a first wake-up mode 1044a and a second wake-up mode 1044 b. In one embodiment, the remote server issues a command to the first Wake-up mode 1044a, the electronic device receives the network packet with the command and analyzes the network packet, and after confirmation, the electronic device immediately executes the boot program, where the first Wake-up mode 1044a is Wake-on-LAN (WoL). In another embodiment, the second wake-up mode 1044b is an improved first wake-up mode, in which a specific processor is loaded by a remote server and an electronic device, a specific system is embedded, and a remote administrator controls a plurality of electronic devices and their internal document data through a network, and the second wake-up mode 1044b is intel vPro technology (intel botle). In the preferred embodiment, the remote wake-up 1044 further includes a third wake-up mode 1044c, which improves data security based on the improvement of the first and second wake-up modes 1044a and 1044b, wherein vPro is used as a seed computer, which is further coupled to a plurality of electronic devices, such as a desktop computer, a notebook computer or a tablet computer, and a manager performs condition setting on the seed computer, such as an on condition 1022 or an off condition 1024, and the seed computer wakes up through a network to control the plurality of electronic devices, i.e., only one seed computer is needed to simultaneously control the backup of the plurality of electronic devices, and further, the backup of different instructions can be performed for different electronic devices.
Step 307: data segmentation is performed. The segmenting module 202 is coupled between the wake-up module 104 and the backup module 106, and after the power state of the electronic device is woken up, the segmenting module 202 segments the data to be backed up, so as to segment the large file into small files, for example: the unit is 64K, but not limited thereto.
Step 308: a backup is performed. The backup module 106 receives the instruction from the wakeup module 104 and then 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 data backup, and is used for fully backing up all file data, and if the data file to be backed up is greater than a specific value, the backup is divided in parallel, the large file is divided into several small files, and then the small files are sequentially backed up and backed up respectively, so as to facilitate the subsequent compression and encryption. In another preferred embodiment, the differential backup mode 1064 is based on the full backup mode 1062, and only partially changed files are backed up, and the differential backup mode 1064 is executed according to the name, time or size of the file change, for example, different from the initial backup state. In general, the full backup mode 1062 is performed only once, and the differential backup mode 1064 must be performed several times based on the previous backup data. Those skilled in the art will appreciate that the full backup mode 1062 and the differential backup mode 1064 are not limited to the above embodiments, and may be changed according to the requirement of the client.
Step 307 and step 308 may be performed concurrently, or may be performed independently, without any restriction on the order of execution, and step 307 may occur after step 308, i.e., backup followed by segmentation.
Step 310: the backup data is compressed or/and encrypted, the step is optional, and the compression step and the encryption step can be executed in parallel or independently without sequence limitation. The backup data described herein can be stored in the memory unit 114 of the original electronic device, transmitted to a remote server via a network, or a combination thereof, thereby achieving the synchronization effect.
Step 311: an optional step is performed to integrate the plurality of ciphertext fragments into ciphertext data, depending on whether there is any data partitioning performed in advance in step 307. The plurality of segments segmented in step 307 and the encrypted segments compressed and encrypted in step 308 are integrated into ciphertext data by an integration module (not shown), which is stored in the memory unit 114 of the original electronic device, transmitted to a remote server via a network, or a combination thereof. In one embodiment, the integration step is implemented by the compression module 108, and the integration step (step 311) and the compression encryption step (step 310) are performed simultaneously.
Step 312: the terminate condition 1024 terminates the wake-up module 104. In one embodiment, after the backup is completed, the termination condition suspends or/and stops the wake-up module 104 to return the electronic device to the initial state. In another embodiment, the termination conditions 1024 include: when the client uses the peripheral device during the backup process, the termination condition 1024 stops or/and suspends the backup module 106 and the wake-up module 104, and returns the electronic device to the initial state.
In another preferred embodiment, the present invention can adopt different wake-up modes and backup modes according to the use time of the client, and can be divided into: referring to fig. 5A and 5B, fig. 5A shows a flowchart of steps of the day wake-up backup mode, and fig. 5B shows a flowchart of steps of the night wake-up backup mode. Referring to fig. 5A, generally speaking, more clients operate the computer during the daytime, and accordingly, the detection module 103 needs to detect the power state of the client computer and corresponds to/selects the start condition 1022 to trigger the near-end wake-up 1042 of the wake-up module 104, so that the electronic device is in a power-on state, and then the backup module 106 will first determine whether a first full backup needs to be performed, and if the first full backup does not need to be performed, obtain a differential backup or an incremental backup. For example, if the client computer is running in the screen saver, the system 100 selects the on condition 1022 that matches the screen saver, generates a related command to trigger the backup module 106 to start running, and the backup module 106 can select one of the full backup 1062 and the differential backup 1064 according to the file capacity. Referring to fig. 5B, at night, the computer is mostly in a power-off or sleep state, at this time, a night wake-up backup mode is required, the detecting module 103 detects the state of the client computer, such as sleep or power-off, and corresponds/selects the power-on condition 1022, triggers the wake-up module 104, and enables the wake-up module 104 to transmit a wake-up packet to the client computer, the wake-up mode is determined according to the actual circuit configuration state, the client computer receives the wake-up packet and triggers the remote wake-up 1044 of the wake-up module 104, so that the electronic device is in a power-on state, and then triggers the backup module 106, which first determines whether to perform a first full backup or not, and if the first full backup is not needed, obtains a path differential backup or an incremental backup, and the backup module 106 also obtains the file capacity to select one of a full backup 1062 or a differential backup 1064, after the backup is completed, the stop condition 1024 stops the wakeup module 104, the subsequent backup module 106 also stops, and the client computer returns to the original state. In the preferred embodiment, the daytime wakeup backup mode and the nighttime wakeup backup mode are used alternately.
