Information is demonstrate,proved, includes the parameters in the verification information, the verification information can be verifying field.
S203, the verification information is added in the communication data, generates new communication data.
In method provided in an embodiment of the present invention, by the way that the verification information to be added in the communication data, generate
It include the new communication data of verification information, it should be noted that when the communication data is data flow, the verifying letter
When breath is verifying field, the verifying field can be added to the end of the data flow.
In method provided in an embodiment of the present invention, by adding verification information in the communication data, it is ensured that second deposits
The new communication data that storage equipment is saved and the communication data saved in the first storage equipment are consistent, it is ensured that
The integrality for the communication data that second storage equipment saves；When trigger it is described second storage equipment to the new communication data into
When row verifying, details are provided below:
It triggers the second storage equipment to parse the new communication data, obtains the verification information, and according to
Consistency checking is carried out to the new communication data according to the verification information, is verified result；
In method provided in an embodiment of the present invention, after the second storage equipment receives the new communication data,
The new communication data is parsed, the verification information in the new communication data is obtained, obtains the verification information
In include parameters, according to the parameters, judge parameters in new communication data whether with the verifying
Parameters in information are consistent, if the parameters in the new communication data and each ginseng in the verification information
Number is consistent, then verification result is consistent；Conversely, then verification result be it is inconsistent, the second storage equipment is to described first
Store equipment feedback validation result.Such as memory size of one of parameter about communication data in verification information, such as
Size type is 1M；Data type of another parameter about communication data, such as data type are video；Second storage
After equipment parses the new communication data, the memory size parameter for obtaining the new communication data is 984K,
Data type is video；Because the memory size that memory size and the parsing of the communication data in verification information obtain is not identical, therefore
Verification result is inconsistent.
Receive the verification result of the second storage equipment feedback, if the verification result be it is inconsistent, to described the
Two storage equipment retransmit the new communication data；
In method provided in an embodiment of the present invention, the first storage equipment receives the verifying of the second storage equipment feedback
As a result, when the verification result be it is inconsistent when, it is described first storage equipment to it is described second storage equipment send again described in
New communication data, to guarantee the communication data that saves in the second storage equipment and be saved in first storing data
Communication data is consistent.
In method provided in an embodiment of the present invention, when the initiating equipment is communicated with the target device, it can be
One initiating equipment is communicated with multiple target devices, is also possible to an initiating equipment and is led to a target device
Letter solves the communication instruction when the first storage equipment receives the communication instruction that the initiating equipment is sent
Analysis, obtains the device id for the target device that the initiating equipment is communicated, and determines according to the device id
Target device, and communication data is sent to corresponding target device, with complete the initiating equipment and the target device it
Between communication, meanwhile, the initiating equipment and the target device are carried out current communication data by the first storage equipment
It is saved, for example, initiating equipment A sends data d to target device B and C, then the first storage equipment saves two communications
Data are that initiating equipment A sends data d and initiating equipment A to target device B and sends data d to target device C respectively；Or
Person only saves a data, i.e. initiating equipment A sends data d to target device B and C；It can be according to actual needs to described first
The mode for storing the preservation communication data of equipment is set.
The derivatization process of above-mentioned each concrete implementation mode and each implementation, all falls in the scope of protection of the present invention.
In method provided in an embodiment of the present invention, communication data is saved by a variety of methods, data is improved and deposits
The stability and reliability of storage system, the embodiment of the invention also provides a kind of data backup systems, for supporting this method to exist
Application in all kinds of storage systems, system construction drawing provided in an embodiment of the present invention is as shown in figure 3, be described as follows described:
A kind of data backup system, comprising: multiple initiating equipments 301, multiple target devices 302, first store equipment
303, the second storage equipment 304, strange land storage equipment 305 and network storage equipment 306；
It is described first storage equipment 303 by network communication protocol (InternetProtccol, IP) respectively with multiple institutes
It states initiating equipment 301 to be connected with multiple target devices 302, it should be noted that the initiating equipment and the target
Equipment is the terminal that can be communicated in local area network, such as computer；Lead between the initiating equipment and the target device
It crosses IP agreement to be attached, and is communicated in setting up the local area network completed, the first storage equipment is initiated for saving
The communication data that equipment is communicated with target device.
The second storage equipment is connected by optical fiber with the first storage equipment, and the second storage equipment is used for
The new communication data received is saved, and consistency checking, Xiang Suoshu first are carried out to the new communication data
Store equipment feedback validation result；When the second storage equipment breaks down for the first storage equipment, as new
First storage equipment works.When the first storage equipment breaks down, the second storage equipment is as the newly
One storage equipment works, then the first new storage equipment by IP agreement respectively with target device and initiating equipment phase
Connection stores the communication data between the target device and initiating equipment, and the first new storage equipment passes through net
Network is connected with network storage equipment and strange land storage equipment respectively, periodically stores equipment to the network storage equipment and strange land
Corresponding data are sent, are saved.
It should be noted that the first storage equipment is saving the communication number between initiating equipment and the target device
According to when, while the communication data being sent in the second storage equipment and is saved, completed local backup, and guarantee institute
It is consistent with the data in the first storage equipment to state the communication data saved in the second storage equipment；It should be noted that
The first storage equipment failure, which can be, to carry out IP connection with the initiating equipment or target device, either
First storage equipment is destroyed, and work can not be normally carried out.
