Specific embodiment
A kind of data back up method of the embodiment of the present invention and device are described in detail with reference to the accompanying drawing.
As shown in Figure 1, the data back up method of the embodiment of the present invention one, comprising:
Step 11 obtains data to be backed up.
In this step, it backup reception data can indicate first, include the number to be backed up in the data backup instruction
According to routing information, such as the store path of the transmission of data to be backed up.Then, it is obtained and the number according to the routing information
Corresponding data to be backed up are indicated according to backup.
Step 12, the resource information for obtaining current system resource.
In embodiments of the present invention, the resource information of the current system resource generally refers to the CPU core number of system, example
Such as four cores.By taking computer as an example, the CPU core number of its system can be obtained by reading the resource information of computer.In general, resource information
It is stored in a configuration file.
Step 13, resource information and the data to be backed up according to the current system resource determine standby for data
The item number of the thread of part, wherein the item number of the thread for data backup is greater than or equal to 2.
In this step, the CPU core number of the system can be obtained by reading the resource information of current system resource, then
The line for data backup corresponding with the CPU core number is determined according to the bandwidth of the CPU core number and the data to be backed up
The item number of journey.Wherein, meet following relationship for the item number n of the thread of data backup:
2≤n≤m, wherein m, n are integer, and m is the CPU core number.
In the specific application process, in the ideal case, it is contemplated that system resource is made full use of, it is described to be used for data backup
The item number of thread can be equal to system CPU nucleus number.But, it is generally the case that due to the idle of system resource and in order to make
It obtains user and observes each system process conveniently, the item number of the thread for data backup determined is usually less than system CPU nucleus number.It is right
For some system, determine that several are used for data backup on the basis of guaranteeing to have at least 2 threads for being used for data backup
Thread be advisable, can be arranged based on experience value.For example, the thread for data backup determined can by taking tetra- core system of CPU as an example
Think 3.
Step 14, the upload for carrying out the data to be backed up simultaneously using the thread for data backup.
It in embodiments of the present invention, can be same using this several threads after the thread item number for data backup has been determined
Shi Jinhang backup.
In this step, can be added to according to the data to be backed up upload sequencing in queue successively will it is described to
Backup Data distributes to the thread for being used for data backup, using the thread of the user data backup carry out simultaneously it is described to
The upload of Backup Data.
For example, the thread for data backup determined can be 3, respectively thread 1 by taking tetra- core system of CPU as an example,
Thread 2, thread 3.Assuming that needing uploading pictures to cloud, the task that data upload in queue is assigned to this three lines
Journey, and three threads upload respective picture simultaneously.Appoint after some thread is transmitted, then for thread distribution is new
Business.
Alternatively, also the data to be backed up can be divided into data block, wherein the quantity of the data block is equal to the use
In the item number of the thread of data backup, the data block is respectively allocated to be used for the thread of data backup, be utilized respectively described
The thread of user data backup carries out the upload of the data to be backed up simultaneously.
It should be noted that can be hung up, when some thread uploads data when something goes wrong then according to predetermined policy
Data to be backed up are assigned to other threads to upload.Predetermined policy can be with are as follows: cannot upload number when thread goes wrong
According to when, remaining data to be uploaded can be evenly distributed in other threads；Or by remaining data to be uploaded according to line
The information such as coding/position of journey, which postpone, to be assigned in next thread.For example, having thread 1,2,3 to upload data, when thread 1 goes out
Problem is showed, then thread 2 and thread 3 can be assigned to the residue data to be backed up for belonging to thread 1；Alternatively, will directly belong to
The residue data to be backed up of thread 1 are assigned to thread 2.By above-mentioned processing mode, resource can be further comprehensively utilized, is improved
The backup efficiency of data.
By above description as can be seen that since the scheme using the embodiment of the present invention can utilize simultaneously in Backup Data
At least two lines journey carries out simultaneously for this, thus compared with prior art, it is standby that data can be improved using the scheme of the embodiment of the present invention

Step 22, the resource information for obtaining current system resource.
Step 23, resource information and the data to be backed up according to the current system resource determine standby for data
The item number of the thread of part, wherein the item number of the thread for data backup is greater than or equal to 2.
Step 24, the upload for carrying out the data to be backed up simultaneously using the thread for data backup.
Step 25, the data backup progress for obtaining the thread for data backup respectively, display is described to be used for data
The data backup progress of the thread of backup.
By taking the example in embodiment one as an example, the progress of thread 1,2,3 can be obtained respectively, and using the form of progress bar
Show the progress of each process.
Wherein the description of step 21-24 shown in Fig. 2 can refer to the description of preceding method embodiment.

Resource information and the data to be backed up, determine for data backup thread item number, comprising:
Resource information by reading the current system resource obtains the CPU core number of the system；
It is determined according to the bandwidth of the CPU core number and the data to be backed up corresponding with the CPU core number for data backup
Thread item number, the item number n of the thread for data backup meets following relationship:
2≤n≤m, wherein m, n are integer, and m is the CPU core number；
When some thread upload data when something goes wrong, hung up, be then assigned to data to be backed up according to predetermined policy
Other threads are uploaded；The predetermined policy are as follows:, will be remaining to be uploaded when thread, which goes wrong, to upload data
Data are evenly distributed in other threads；Or remaining data to be uploaded are postponed point according to coding/location information of thread
It is fitted in next thread.
