As shown in Fig. 2, the method includes：
Step 202, data to be backed up are sent to multiple backup clients, so that the multiple backup client stores institute
State data to be backed up.
In embodiments of the present invention, need the client (hereinafter referred to as demand for services client) of data backup service will
Data to be backed up are sent to the client i.e. backup client for providing data backup service, and backup client receives number to be backed up
According to rear, data to be backed up are stored to realize the protection for treating Backup Data.In above process, demand for services client will need
The data of backup are stored in other clients, are a kind of distributed data backup modes, can be to avoid in data backup
The risk brought due to concentrating on server end storage.
It should be noted that data to be backed up may include but be not limited only to：File data (Word, Excel, PPT etc.),
Image data (photo, image etc.), audio data (music, voice etc.), video data (animation, video recording etc.) etc..
In addition, multiple backup clients here random can select in backup client cluster, it is not counted
Amount and object are specifically limited.For example, more multiple backups can be sent it to for important data to be backed up
Client is stored, and to reinforce protecting, and can then distribute them to negligible amounts for not too important data to be backed up
Several backup clients storage.The reliability journey of data backup can be regulated and controled by the quantity of the backup client of distribution
Degree, the backup client quantity generally distributed is more, and the reliability of data backup is also higher.
In practical applications, demand for services client can first send the request of Backup Data to each backup client,
After each backup client receives Backup Data request, whether receive asking for Backup Data to the return of demand for services client
It asks, demand for services client receives the backup client of the request of Backup Data according to the acquisition of information that each backup client returns
Data to be backed up, are then sent to the backup client for the request for receiving Backup Data by end.
In order to improve message transmission rate and storage efficiency, data to be backed up can be divided into more by demand for services client
Then multiple data block is sent to backup client by a data block successively.It should be noted that can be by data to be backed up
Several equal-sized data blocks are divided into, the data block that data to be backed up can also be divided into several to differ in size.
When data to be backed up are divided into multiple equal-sized data blocks, segmentation can be set in the configuration file of client

Such as every how many days carry out it is primary.Specifically, can be configured according to the reliability standard of data backup, general data backup
Reliability standard it is higher, send storage state inquiry request the frequency it is higher, i.e., time interval is shorter.
In practical applications, can timer be set in demand for services client, specific hair is set by timer
The time for sending storage state inquiry request, either time interval when the time or time interval for reaching setting, gave by timer
Go out to send the signal of corresponding state data memory inquiry request to be backed up, demand for services client sends phase according to the signal
The request answered.
It should be noted that sent to backup client the storage state inquiry request of data to be backed up time or when
Between be spaced and can be adjusted according to actual demand, for example, can be according to the reliability step of stored data to be backed up
It is required that variation, the variation of carrying cost are adjusted.
In addition, before the storage state inquiry request for sending data to be backed up, demand for services client can pass through day
Will file acquisition stores the hardware identifier of the backup client of the data to be backed up, then to the backup client of corresponding hardware identifier
End sends the storage state inquiry request of the data to be backed up.
It should be noted that carrying the file of corresponding data to be backed up in the storage state inquiry request of data to be backed up
Name is searched for backup client according to file name.
Step 304, the storage state information for the data to be backed up that each backup client returns is obtained.
In this specification embodiment, the storage state information of data to be backed up includes normal storage state and abnormal storage
State includes currently without storing data to be backed up and currently stored data to be backed up not when for abnormal storage state
Completely.
In practical applications, it after backup client receives the storage state inquiry requests of data to be backed up, obtains first
The filename of the data to be backed up is taken, whether above-mentioned data to be backed up are currently then stored with according to file name lookup, when not having
When finding above-mentioned data to be backed up, it is standby to be waited for currently without storage to return to current storage state to demand for services client
Part data are abnormal to store；When finding above-mentioned data to be backed up, further determine that whether currently stored data to be backed up are complete
It is whole.
Specifically, when determining whether currently stored data to be backed up complete, it can be in conjunction with the specific of data to be backed up
Storage mode.For example, the MD5 values of currently stored data to be backed up can be calculated, and compare currently stored data to be backed up
MD5 values and the MD5 values of initial data to be backed up consistency, if the two is consistent, then it represents that currently stored number to be backed up
According to complete, it is normal storage that can return to current storage state, indicates currently stored data to be backed up not if inconsistent
Completely, it is abnormal store that can return to current state of depositing.It, can when data to be backed up are stored in the form of multiple data blocks
To obtain the quantity of currently stored data block and the MD5 values of each data block, and it is initial with data to be backed up to compare it
Whether data number of blocks and the MD5 values of data block are consistent, indicate that currently stored data to be backed up are complete if consistent, can return
It is normal storage to return current storage state, indicates that currently stored data to be backed up are imperfect if inconsistent, can return
Current state of depositing is abnormal stores.
Step 206, survival verification is carried out to the data to be backed up according to the storage state information.
In this specification embodiment, storage state message reflection that each backup client returns data to be backed up are in phase
Answer the storage state in backup client, including normal storage state and abnormal storage state.Survival verification is worked as to confirm
Whether the preceding data volume to be backed up in normal storage state meets the reliability step requirement of the data to be backed up, so as to not
It when meeting the requirements, adjusts in time, ensure that the reliability and Dynamic dexterity of data backup.
In a specific embodiment, as shown in figure 4, it is described according to the storage state information to the number to be backed up
May include according to survival verification is carried out：
Step 402, according to the survival volume of data to be backed up described in the storage state acquisition of information.
In embodiments of the present invention, the survival volume of data to be backed up can be that data to be backed up are in normal storage state
Number can also be the ratio that data to be backed up are in the number of normal storage state and the distribution quantity of data to be backed up.
Furthermore, it is necessary to explanation, in the embodiment of the present invention, the survival volumes of the data to be backed up is not limited in above-mentioned
Several forms, can also include other in practical applications can characterize the particular value of data storing reliability to be backed up, this
Inventive embodiments are not limited with above-mentioned.
Step 404, judge whether the survival volume is less than predetermined threshold value.
In embodiments of the present invention, predetermined threshold value can in conjunction with treat in practical application the reliability step of Backup Data with
And carrying cost requires to be set.In general, predetermined threshold value is bigger, the reliability requirement for treating Backup Data is higher, storage
Cost is higher；Conversely, predetermined threshold value is smaller, the reliability requirement for treating Backup Data is lower, and carrying cost is lower.In addition, this
In the specific numerical value of predetermined threshold value linear module can be carried out in conjunction with the survival volume of data to be backed up in practical application it is corresponding
Adjustment.
In a specific embodiment, when the survival volume of the data to be backed up is that data to be backed up are in normal storage
When the ratio of the number of state and the distribution quantity of data to be backed up, the linear module of the predetermined threshold value can be percentage.
Specifically, for example the predetermined threshold value could be provided as 30%.
It should be noted that in this specification embodiment, the predetermined threshold value of stored data to be backed up can basis
Requirement to carrying cost and the requirement to reliability step are adjusted, if for example, the weight of stored data to be backed up
It wants degree to improve, then correspondingly, the requirement to the reliability step of the data to be backed up needs to improve, increase can be taken
Predetermined threshold value can also be taken to realize and increase predetermined threshold value and improve the frequency that survival is verified certainly；If conversely, stored
The significance level of data to be backed up reduces, then correspondingly, the requirement to the reliability step of the data to be backed up may need
It reduces, can take and reduce predetermined threshold value to realize, can also take certainly and reduce predetermined threshold value and reduce survival verification
The frequency.Certainly, it when carrying cost needs adjustment, can also be realized by changing predetermined threshold value.

If threshold value, then it can determine that the storage of current data to be backed up can meet the reliability step requirement to the data to be backed up,
Correspondingly, recording, the data storage to be backed up is normal, and verification terminates.
Step 408, when the survival volume is less than predetermined threshold value, it is abnormal to record the data storage to be backed up.
In embodiments of the present invention, if the result judged is yes, i.e., the survival volume of data to be backed up is less than predetermined threshold value, then
It can determine that the storage of current data to be backed up cannot meet the reliability step requirement to the data to be backed up, it is current to be backed up
The storage of data is dangerous, correspondingly, it is abnormal to record the data storage to be backed up.Determining that current data storage to be backed up is abnormal
When, execute step 410.
Step 410, according to the abnormal backup client of storage state information searching storage.
It, can be according to the storage state information of each backup client return when determining that current data storage to be backed up is abnormal
The backup client that data to be backed up are in abnormal storage state is obtained, and these backup clients are labeled as storage exception
Backup client.
Step 412, the data to be backed up are retransmitted to the abnormal backup client of the storage.
In embodiments of the present invention, after confirming the abnormal backup client of storage, demand for services client is again
The backup client abnormal to storage sends data to be backed up so that the abnormal backup client of storage store again this wait for it is standby
Part data.
Data to be backed up are specifically sent to the abnormal backup client of storage and are referred to abovementioned steps 202, herein
It repeats no more.
It should be noted that backup client when storing data to be backed up again, may be repeated data deletion, with
Optimize the memory space of backup client, for example, the method based on hash (hash), which may be used, carries out data de-duplication.
In a specific embodiment, as shown in figure 5, described in being retransmitted to the abnormal backup client of the storage
Before data to be backed up, can also include：
Step 502, judge locally whether be stored with the data to be backed up.
In embodiments of the present invention, data to be backed up are sent to by multiple backup visitors for the first time due to demand for services client
It after the end of family, can select the data to be backed up not to be stored in local, therefore, when demand for services client needs to send again
When the data to be backed up are to storage abnormal backup client, need to first determine whether locally whether be stored with the data to be backed up,
When locally no storage data to be backed up, step 504 is executed, when the data to be backed up have been locally stored, then directly
It connects from the local backup client for obtaining the data to be backed up and sending it to storage exception.
Step 504, when locally no storage data to be backed up, from the backup visitor for being stored with the data to be backed up
Family end obtains the data to be backed up.
In embodiments of the present invention, after demand for services client confirms the local data to be backed up without storage, Ke Yixiang
Any one or the multiple backup clients for being stored with the data to be backed up send the request for obtaining data to be backed up, backup visitor
Family end, which receives above-mentioned request and determines to demand for services client, sends data to be backed up, so that demand for services client can
Obtain the data to be backed up.
Step 506, the data to be backed up are saved in local.
After demand for services client gets the data to be backed up of backup client transmission, which is saved in
It is local, in this way, when retransmitting the data to be backed up to the abnormal backup client of storage, can from it is local get wait for it is standby
Part data.
The technical solution provided by above this specification embodiment is as it can be seen that by by number to be backed up in this specification embodiment
It according to being stored in multiple backup clients, and periodically treats Backup Data and carries out survival verification, greatly reduce data to be backed up
It is accidentally deleted and risk that hacker attacks is deleted, improves the reliability of data backup, it is not busy using various regions due to can be very good
The memory space in backup client set, to eliminate the cost for buying special storage disk and plant maintenance, because
This, effectively reduces the carrying cost of Backup Data.
In addition, data back up method in the prior art adjusts reliability and cost with being difficult to dynamic flexible.Actual
In data backup procedure, since the safe class requirement of data is different, different period, the safe class of identical data
It is required that may also can change, and demand of the data backup to space be also in dynamic change, therefore, the storage that user oneself purchases
It is difficult to meet the requirement of above-mentioned dynamic change that medium, which carries out data backup, and if to fully meet the reliable of above-mentioned data backup
Property and can memory space requirements, and prodigious waste will certainly be caused, lead to the increase of carrying cost.
And the data back up method that this specification embodiment provides can by control data to be backed up distribution quantity, into
The time interval of row survival verification and the reliability of data to be backed up regulated and controled for the setting of the predetermined threshold value of survival volume, from
And neatly dynamic can be carried out between carrying cost and reliability requirement and is adjusted.
