Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, and below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the process flow diagram of the data back up method embodiment based on cloud storage of the present invention.As shown in Figure 1, described method can comprise:
Step 101: obtain data backup task information; Described data backup task information comprises source data server address information;
Source data server can in different geographic position, such as can in Beijing, also can in Shanghai.Be positioned at the source data server of diverse location, different source data server address informations can be had.One_to_one corresponding between source data server address information and source data server.
Step 102: according to described source data server address information, search data backup client; The address information of described data backup client is corresponding with described source data server address information, and described data backup client is pre-installed in described source data server;
Data backup client can be mounted in the client in source data server.Because described data backup client is pre-installed in described source data server, so described data backup client is when obtaining the data to be backed up in described source data server, do not need through Internet Transmission, data backup client can be improved in the speed obtaining the data to be backed up in described source data server.
Step 103: call described data backup client and carry out data backup.
Describedly call described data backup client and carry out data backup, can comprise:
Steps A: described data backup client obtains the data to be backed up in described source data server;
Step B: described data to be backed up are sent to the data memory node in cloud storage system by network;
Step C: described data memory node backs up described data to be backed up.
In sum, the data back up method stored based on cloud of the present invention, by installation data backup client in source data server in advance, the address information of described data backup client is corresponding with described source data server address information, the network transmission process of data backup client when obtaining the data to be backed up in described source data server can be saved, and then data backup client can be improved in the speed obtaining the data to be backed up in described source data server.
It should be noted that, data back up method of the present invention stores based on cloud, is applicable to open internet environment.Data back up method of the present invention, source data server can be multiple.Can installation data backup client in each source data server.Each data backup client can back up the data in source data server simultaneously.Therefore, along with the increase of source data server, adopt method and system of the present invention dilatation to store, larger data throughout is provided.Especially, in cloud storage system, its performance is along with the substantially linear growth of increase of quantity of source data server carrying out concurrent backup.
In practical application, the data memory node in cloud storage system can have multiple.The network transfer speeds of different data memory nodes is different.In order to improve data backup speed further, network transfer speeds data memory node faster can be selected.Concrete, step B, can comprise again:
Step B1: send measurement data respectively to each data memory node in described cloud storage system; Described measurement data includes exempts from write mark, described in exempt to write mark and be used to indicate the ablation process shielded after data memory node receives described measurement data for described measurement data;
Described exempting from writes the specific fields that mark can be the packet header being positioned at described packet.Such as when packet header is " 0 ", can represent that corresponding packet does not need write.
Exempt from write mark owing to have employed, the packet that will not test the speed write data memory node, so can improve the efficiency that tests the speed, saves and tests the speed the time.
Step B2: according to the transmission time of described measurement data, determines the network transfer speeds of each data memory node;
Because described measurement data need not be written into, thus according to the transmission time of described measurement data can be more accurate the network transfer speeds of data memory node corresponding to determination.
Step B3: the data memory node selecting network transfer speeds the fastest is as destination node;
Step B4: described data to be backed up are sent to described destination node by network.

m+1represent the network transfer speeds measuring the data memory node obtained for the m+1 time,
represent the initial value for the moving average of the network transfer speeds of data memory node, n represents the pendulous frequency of the network transfer speeds for data memory node.
It should be noted that, in step B2, adopt the network transfer speeds of simple moving average value-based algorithm to data memory node to calculate.Because the simple method of moving average can reflect the time dependent trend of network transfer speeds, so adopt simple moving average to calculate the network transfer speeds of data memory node in step B2, relative to the network transfer speeds adopting common average value to calculate data memory node, more accurately.
In addition, for the process that tests the speed of data memory node, can perform when described data backup client is idle.When described data backup client is in the process performing backup tasks, according to the implementation of this backup tasks, the first network transmission speed of this backup tasks can also be got.When supposing idle according to described data backup client, the network transfer speeds of this data memory node that measurement obtains is second network transmission speed, then according to described first network transmission speed and described second network transmission speed, can more accurately calculate the network transfer speeds of this data memory node.
In practical application, be effective in order to ensure the data backup client found in step 102, step 102 can comprise:
Step 1021: judge whether the heartbeat message receiving described data backup client in Preset Time, obtain the first judged result;
Heartbeat message can be the message that described data backup client periodically sends, for feeding back the validity of self.When described data backup client is in idle condition, when can be used, periodically heartbeat message can be sent.When described data backup client is in occupied state, when cannot be used, then heartbeat message can not be sent.
Step 1022: when described first judged result represents the heartbeat message receiving described data backup client in Preset Time, call the step that described data backup client carries out data backup described in execution;
Step 1023: when described first judged result represents the heartbeat message not receiving described data backup client in Preset Time, stops calling the step that described data backup client carries out data backup described in execution.
In step 1023, after can also waiting for that described data backup client sends heartbeat message, then call the step that described data backup client carries out data backup.
