detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. In addition, the terms "first", "second", and "third", etc. are used to distinguish different objects, and are not used to describe a specific order.

In one embodiment, a method for backing up data by a terminal is provided. The implementation of the method may rely on a computer program, the computer program may run on a computer system based on the Von Neumann architecture, the computer program involves a backup terminal and a target terminal communicating with the backup terminal, the backup terminal and the target terminal Including but not limited to smart phones, tablets, handheld computers, laptops or personal computers and other terminal devices. The computer program can be an independent application in the backup software on the terminal, or it can be a function option or application plug-in developed based on the backup software application, and can be installed in terminal devices running IOS, Android, Windows Phone and other operating systems.

Specifically, as shown in Figure 1, a method for terminal backup data includes:

Step S102: Obtain the capacity and backup speed of the remaining storage space of the backup terminal, and detect the transmission speed of the backup terminal to the target terminal;

Smartphones, tablet computers, handheld computers, laptops or personal computers can be transmitted between terminals such as Bluetooth or infrared, Wi-Fi or data traffic, data cables connected to hardware storage devices such as hard disks or U disks, etc. The transmission speed depends on the transmission medium and the size of the data to be transmitted. For example, the transmission speed of a hard disk is significantly faster than that of a USB flash drive, and the transmission speed of Wi-Fi is faster than that of data traffic.

It should be noted that the transmission network status can be in the case of Wi-Fi, or in the case of 2G\3G\4G data traffic. Settings are only backed up over Wi-Fi.

Step S104: Calculate the ratio of the backup speed to the transmission speed, and determine the size of the first cache space according to the ratio and the capacity of the remaining storage space;

Both backup and transmission take a certain amount of time. In order to save transmission time and avoid backup failure caused by the storage capacity of the data to be backed up is greater than the storage capacity of the backup terminal, the data to be backed up can be divided into multiple data packets of a specific size, and the backup is complete. A data packet can be written to the target terminal, thus speeding up the transfer process.

The backup speed is usually faster than the transmission speed, and the ratio of the backup speed to the transmission speed can be an integer or a decimal, and the decimal is rounded up, rounded down or rounded up, etc. According to the calculated ratio of the backup speed to the transmission speed and the capacity of the remaining storage space, the remaining storage space is divided into at least two cache spaces, and the cache spaces do not overlap. It can be understood that the smaller the capacity of the cache space is, the shorter the total backup time is, thereby improving the efficiency of backup data and the utilization rate of storage space.

For example, the remaining space of the original mobile terminal is 1G, the transmission speed is faster such as 10M/s, and the backup speed is also 20M/s, then the ratio of the transmission speed to the backup data is 2, and the capacity of the cache space can be set to 300M.

Step S106: writing the data to be backed up into the first cache space, and determining that the data contained in the first cache space is the first backup data packet;

The data to be backed up includes not only the data itself, but also basic data information such as the name of the data to be backed up, the data type, and the relative path stored on the backup terminal. When the data to be backed up is written into the first cache space, the first backup data packet includes the data to be backed up and basic data information of the data to be backed up.

Step S108: When the first backup data packet reaches the size of the first buffer space, transmit the first backup data packet to the target terminal.

After the first backup data packet is transmitted to the target terminal, the target terminal analyzes the data in the first backup data packet. Specifically: after the transmission of the first backup data packet to the target terminal is completed, the target terminal decompresses the first backup data packet, and stores the data contained in the first backup data packet. The target terminal may obtain the relative path stored in the data or data type in the first backup data packet, and store the corresponding data to be backed up under the relative path of the target terminal. The target terminal can also be stored in the default location of the system, or the user can be prompted to choose the storage path of the backup data.

After the transmission of the first backup data packet is completed, the target cache space should be cleared in time to make room for subsequent backup data, ensuring that the process of backup data and data transmission is carried out at the same time, and improving the efficiency of data backup and the utilization rate of storage space. Specifically: clear the first buffer space when the transmission of the first backup data packet to the target terminal is completed.

At the same time, if there is still data to be backed up, since the backup data packets do not overlap, the capacity of the current remaining storage space is sufficient to back up the next backup data packet. Once the backup is completed, the backup data packet will be written to the target terminal until Stop the backup after all the backup data is transmitted to the target terminal, thereby improving data backup efficiency and storage space utilization. Specifically: determine the size of the second cache space according to the ratio and the capacity of the remaining storage space, and the second cache space has no intersection with the first cache space; when transmitting the first backup data packet At this time, at least a part of the data to be backed up other than the first backup data package is written into the second cache space, and the data contained in the second cache space is determined to be the second backup data package.

In one of the embodiments, the method further includes transmitting the second backup data packet to the target terminal after the transmission of the first backup data packet to the target terminal is completed. Preferably, when the transmission speed is equal to the backup speed, the buffer space can be set to half of the data to be backed up, that is to say, when the target terminal receives the first backup data packet, the backup terminal backs up the second backup data packet, when the target terminal While the terminal receives the second backup data packet, the original mobile terminal backs up the third backup data packet, and so on, so as to ensure the synchronous execution of the backup operation and the transmission operation. Specifically: when the ratio between the backup speed and the transmission speed is 1, the capacity of the target cache space is 1/2 of the capacity of the remaining storage space.

For example, consider an application scenario where a specific terminal backs up data. As shown in Figure 2, the remaining space of the backup terminal is 1G, the transmission speed is relatively fast, such as 20M/s, and the backup speed is also 20M/s, so it can be determined that the backup data size is 500M. After the backup terminal backs up to 500M, the first backup data packet is transmitted, and the second backup data packet is backed up during the transmission. Of course, the capacity of the second storage space is also 500M. When the transmission of the first backup data packet is completed, the second backup data packet is transmitted, and at the same time, the first backup data packet is cleared, unnecessary buffers in the remaining buffer space are cleared, and this process is completed alternately in a cycle until the data to be backed up of the backup terminal is completed All migration, thus improving the efficiency of data backup and utilization of storage space.

It should be noted that due to the limited capacity of the data to be backed up, there are cases where the cache space cannot be filled. When there is a situation that the cache space cannot be filled, write all the remaining data to be backed up into the cache space and transmit the backup data packet to the target terminal.

For the data to be backed up, you can choose all the user data by default in the system, or user-defined contacts, pictures, videos, audio and documents, etc. Specifically: before writing the data to be backed up into the first cache space, it also includes: detecting the instruction of the selected backup data type, and writing the data to be backed up corresponding to the selected backup data type instruction into the first cache space.

Combined with a specific application scenario of selecting data to be backed up, as shown in Figure 3, the user selects the preferred data type for backup as contacts through the graphical user interface of the terminal, and then selects the OK button to realize the contact The change. It should be noted that multiple data types can be selected or all user data can be backed up.

When an abnormality occurs in the backup, the terminal will return a prompt message to the user to let the user know that there is a failure in the process of backing up the data and the backup cannot be performed normally. Specifically: when an exception occurs during the writing process, a prompt message is sent.
