Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.In addition, term " first ", " second " and " third " etc. are for distinguishing difference Object, and be not intended to describe specific sequence.
In one embodiment it is proposed that a kind of method of terminal backup data.The realization of this method can be dependent on calculating Machine program, the computer program can run on the computer system based on von Neumann system, which is related to Back-up terminals and the target terminal being communicatively coupled with back-up terminals, back-up terminals and target terminal include but is not limited to intelligence Mobile phone, tablet computer, palm PC, laptop or PC etc. terminal device.The computer program can be end An independent application in backup software on end, is also possible to function choosing-item or application based on backup software application and development Plug-in unit, it is mountable in the terminal device of the operating systems such as operation IOS, Android, Windows Phone.
Specifically, as shown in Figure 1, a kind of method of terminal backup data, comprising:
Step S102: the amount of capacity and backup rate of the residual memory space of back-up terminals are obtained, the backup is detected Transmission speed of the terminal to target terminal;
Smart phone, tablet computer, palm PC, the transmission mode between laptop or PC etc. terminal Bluetooth or infrared, Wi-Fi or data traffic, data line connection hardware storage device such as hard disk or USB flash disk etc. can be used.Transmission speed Degree depends on transmission medium and data capacity size to be transmitted, such as the transmission speed of hard disk to be significantly faster than that USB flash disk, Wi-Fi's Transmission speed is faster than the transmission speed of data traffic.
It should be noted that in the case of the network state of transmission can be Wi-Fi, be also possible to 2G 3G the data flows such as 4G The case where amount, reduces unnecessary rate waste, can be arranged in terminal device and only exist to save the usage amount of customer flow It is backed up in the case of Wi-Fi.
Step S104: calculating the ratio of the backup rate Yu the transmission speed, according to the ratio and the residue The amount of capacity of memory space determines the size of the first spatial cache;
Backup and transmission require the regular hour, in order to save the time of transmission and avoid because data to be backed up are deposited It stores up capacity and is greater than backup failure caused by the memory capacity of back-up terminals, data to be backed up can be divided into the number of multiple particular sizes According to packet, a data packet, that is, writable target terminal is completed in backup, to accelerate the process of transmission.
Backup rate would generally be faster than transmission speed, and the ratio of backup rate and transmission speed can be integer, can also Think decimal, decimal is by the way of rounding up, decimal is rounded downwards or decimal rounds up etc. mode is rounded.According to The ratio of the backup rate and transmission speed that are calculated and the amount of capacity of residual memory space, residual memory space is divided into At least two spatial caches, and do not overlapped between spatial cache.It is understood that the amount of capacity equipment of spatial cache is got over Small, then the total duration backed up is shorter, to improve the efficiency of Backup Data and the utilization rate of memory space.
For example, the remaining space of originating mobile terminal is 1G, and comparatively fast such as 10M/s, backup rate are also transmission speed 20M/s, then the ratio of transmission speed and Backup Data is 2, and the amount of capacity of spatial cache may be configured as 300M.
Step S106: being written first spatial cache for data to be backed up, determines in first spatial cache and includes Data be the first backup data package;
Data to be backed up include the title for further comprising data to be backed up outside data itself, data type and are backing up eventually The data essential information such as relative path stored on end.When the first spatial cache is written in data to be backed up, the first Backup Data Bao Ze contains the data essential information of data to be backed up and data to be backed up.
Step S108: when the first backup data package reaches the first spatial cache size, by the first backup number The target terminal is transferred to according to packet.
After first backup data package is transferred to the target terminal, target terminal is in the first backup data package Data are parsed.It is specific: first backup data package is transferred to after the target terminal completes described, it is described Target terminal decompresses first backup data package, stores the data for including in first backup data package.Target terminal can The relative path that data or data type in the first backup data package are stored is obtained, corresponding data to be backed up are stored Under the relative path of target terminal.Target terminal is also storable under the position of system default, or prompt user is selective Backup Data store path.
Target cache space should be emptied in time after the first backup data package is transmitted, vacate sky for subsequent backup data Between, it is ensured that the process of Backup Data and transmission data carries out simultaneously, improves the efficiency of data backup and the benefit of memory space With rate.It is specific: when first backup data package is transferred to target terminal completion, it is empty to empty first caching Between.
At the same time, if there is also data to be backed up, due to not overlapped between backup data package, current residual storage space Amount of capacity be enough to back up next backup data package, target terminal is written into backup data package once backing up and completing, directly Stop backup after being all transferred to target terminal to data to be backed up, to improve the backup efficiency of data and the benefit of memory space With rate.It is specific: the size of the second spatial cache is determined according to the amount of capacity of the ratio and the residual memory space, and Second spatial cache and first spatial cache are without intersection;It is standby by first when transmitting first backup data package Second spatial cache is written at least part data to be backed up other than part data packet, determines in second spatial cache The data for including are the second backup data package.
In one of the embodiments, the method also includes it is described first backup data package is transferred to it is described After target terminal is completed, second backup data package is transmitted to the target terminal.Preferably, when transmission speed and backup When speed is equal, spatial cache can be set to the half of data to be backed up, that is to say, that when target terminal reception first is standby While part data packet, back-up terminals back up the second backup data package, while target terminal receives the second backup data package, Originating mobile terminal backup third backup data package, and so on, guarantee backup operation execution synchronous with transmission operation.Tool Body: when the ratio between the backup rate and the transmission speed is 1, the amount of capacity in the target cache space is The 1/2 of the amount of capacity of the residual memory space.
For example, in conjunction with the application scenarios of a specific terminal backup data.The residue of back-up terminals as shown in Figure 2 is empty Between be 1G, for transmission speed comparatively fast such as 20M/s, backup rate is also 20M/s, then can determine that Backup Data size is 500M. After back-up terminals backup to 500M, the second backup is carried out in the transmission process of the first backup data package of progress, in transmission process The amount of capacity of the backup of data packet, certain second memory space is also 500M.It is passed after the first backup data package is transmitted Defeated second backup data package, while the first backup data package is emptied, unnecessary caching in remaining cache space is cleared up, circulation is handed over This process of the completion replaced, until the data to be backed up for completing back-up terminals all migrate, to improve data backup The utilization rate of efficiency and memory space.
It should be noted that there is the case where cannot writing full spatial cache because amount of capacity is limited in data to be backed up.When When in the presence of the case where cannot writing full spatial cache, spatial cache and backup data transmitting is all written into remaining data to be backed up Wrap target terminal.
With can choose system default whole subscriber datas of data to be backed up, are also possible to the customized connection of user People, picture, video, audio and document etc..It is specific: described that data to be backed up are written before first spatial cache also Include: that Backup Data type instruction is chosen in detection, chooses the corresponding data to be backed up of Backup Data type instruction for described First spatial cache is written.
For the application scenarios for specifically choosing data to be backed up in conjunction with one, as shown in figure 3, the figure that user passes through terminal Shape user interface selects the data type preferentially backed up for contact person, selects confirming button that connection can be realized after selected It is the variation of people.It should be noted that can choose multiple data types or the whole subscriber datas of selection backup.
When backup occurs abnormal, terminal can return to prompt information to user, let the user know that the process of Backup Data goes out Having showed failure cannot proceed normally backup.It is specific: when occurring abnormal in writing process, to send prompt information.
