Embodiment 1
[0038] figure 1 It is a flow chart of a data verification method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of performing both cost and accuracy verification on the backup data. The method can be executed by a data verification device, and the device can be realized by software and / or hardware. see figure 1 , the data verification method provided in this embodiment includes:
[0039] S110. Extract the attribute value of the source data and the attribute value of the backup data.
[0040] Wherein, the attribute value of the source data is determined according to the source data, and the data amount of the attribute value of the source data is smaller than the data amount of the source data. The attribute value of the backup data is determined according to the backup data, and the data amount of the attribute value of the backup data is smaller than the data amount of the backup data.
[0041] The source data is the source d...
Embodiment 2
[0070] figure 2 It is a flow chart of a data verification method provided by Embodiment 2 of the present invention. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see figure 2 , the data verification method provided in this embodiment includes:
[0071] S210. Generate an attribute value of the source data according to the source data, and generate an attribute value of the backup data according to the backup data.
[0072] S220. Store the generated attribute value in the attribute storage unit.
[0073] Specifically, the generated attribute value of the source data is stored in the attribute storage unit of the source data, and the generated attribute value of the backup data is stored in the attribute storage unit of the backup data.
[0074] The storage unit may be a correspondingly consistent storage unit with the source data.
[0075] Typically, see image 3 , the attribute storage unit includes attribute location index ...
Embodiment 3
[0121] This embodiment is an optional solution proposed on the basis of the foregoing embodiments. The data verification method provided in this embodiment includes:
[0122] attribute value generation
[0123] Wherein, attribute value generation includes determination of attribute value acquisition method, attribute value storage format and attribute value generation method.
[0124] The attribute acquisition method is as follows: For fields of fixed-length data types such as bool, int, and long, the original value is directly used as the attribute value because it occupies a small space. For variable-length data types such as string and Binary, the space occupied by the actual value may be large, and it is not suitable to use the original value as the attribute value, so the summary of the type of data is used as the attribute value. This attribute acquisition method can not only save space, but also ensure the accuracy of data.
[0125] Wherein, the digest extraction met...
