It should be noted that, production inventory device generates SHA-1 authority checking code according to the random number challenge generated, can be complete after receiving the request sent to production inventory device after calamity generates SHA-1 identifying code for memory according to random number challenge, be not construed as limiting herein.

Production inventory device sends the data A needing backup for memory to calamity, data A comprises corresponding SHA-1 authority checking code, the data B that calamity sends for memory reception production inventory device;

It should be noted that, calamity can also comprise service numbers (transcationID) for the data A that memory receives, and is not construed as limiting herein.

Calamity judges whether there is the SHA-1 authority checking code identical with SHA-1 identifying code in described data B for memory, if, then calamity receives in production inventory device corresponding to this SHA-1 identifying code the data A needing to back up for memory, if not, directly can determine that data A is variance data, a lot of data backup may be had because production inventory device once backs up, can send in calamity for memory several times, therefore also can be that calamity continues to receive some data C for memory, judge in described data C, whether to there is the SHA-1 authority checking code corresponding with SHA-1 identifying code, if, then calamity receives in production inventory device corresponding to this SHA-1 identifying code the data A needing to back up for memory, if not, determine that data A is variance data, be not construed as limiting herein,

Need the data backed up may have a lot in production inventory device, can be send to calamity to carry out data verification backup for memory by file, for playing file, can also be send to calamity to carry out data verification backup for memory after splitting according to the rule of setting, as by file division being the data of setting size, send to calamity for memory, as 100kb, 1M etc.

Each data needing backup in production inventory device, the flow process all backed up according to above-mentioned data verification is carried out, after completing all data verifications, the variance data between the data that calamity can determine to need in described production inventory device the data that back up and described calamity to receive for memory for memory.

Calamity after determining the variance data between the data that in production inventory device, all data to be sent and calamity receive for memory, can return the information of variance data for memory to production inventory device.

Production inventory device can retransmit described variance data to calamity for memory, the SHA-1 authority checking code of the correspondence generated before each described variance data comprises after receiving the variance data information that calamity sends for memory.

After calamity receives the described variance data of production inventory device transmission for memory, the SHA-1 identifying code corresponding to each described variance data, judge whether there is the SHA-1 authority checking code identical with SHA-1 identifying code in the variance data received, whether receive all described variance data according to judged result determination calamity for memory.

When also there is the variance data do not received, can continue to retransmit the data that do not receive with reference to above-mentioned steps, need in production inventory device the data full backup that backs up to calamity for memory.

In the present embodiment, in order to Appropriate application storage resources, the storage space that can divide setting size for memory in calamity is headspace, as 0.5% of storage space, the judged result of each SHA-1 identifying code and SHA-1 authority checking code is stored in described headspace, is not construed as limiting herein.

When there is not described variance data for memory in calamity, or there are described data, after retransmitting described variance data, when determining to receive all described variance data, namely not there are differences data between the data that now all data to be sent and described calamity receive for memory in production inventory device, calamity can identify to production inventory device return data consistency for memory, is not construed as limiting herein.

Introduce the embodiment of the calamity in the embodiment of the present invention for memory below, refer to Fig. 7, the calamity in the embodiment of the present invention comprises for an embodiment of memory:
