Abstract

A method includes that the data storage path information used by a data object in a target query time period is determined, that a target operation object through which the data object written from a source end to a destination end passes is determined from the data storage path information, and that a storage situation of the data object in the target query time period is predicted and determined by performing a storage-affecting event analysis on the target operation object.

First claim

What is claimed is:

1 . A data retrieval prediction method performed by a data retrieval prediction apparatus applied in a security system, comprising:
determining data storage path information used by a data object in a target query time period; determining, from the data storage path information, a target operation object through which the data object written from a source end to a destination end passes, wherein the target operation object through which the data object written from the source end to the destination end passes comprises at least two of a front-end collection device, a server, a switch device, a storage end device, a storage end device grouping, a disk, an array, a user start-stop storage operation, or an alarm linkage start-stop storage operation; and predicting and determining a storage situation of the data object in the target query time period by performing a storage-affecting event analysis on the target operation object; wherein predicting and determining the storage situation of the data object in the target query time period by performing the storage-affecting event analysis on the target operation object comprises: performing, based on pre-stored affecting event configuration information, the storage-affecting event analysis on the target operation object through which the data object written from the source end to the destination end passes; and predicting and determining the storage situation of the data object in the target query time period according to a result of the storage-affecting event analysis on the target operation object, wherein the affecting event configuration information comprises a storage-affecting event record of a data storage effect arising from writing of the data object from the source end to the destination end; and the storage-affecting event record comprises an operation object identifier for affecting data storage, description of an affecting event, start time of an affecting event, and end time of an affecting event; wherein the data retrieval prediction method further comprises: updating and correcting, through a bypass device associated with a target operation object affecting data storage, a storage-affecting event record of the target operation object affecting data storage in the affecting event configuration information; wherein the bypass device and the target operation object affecting data storage satisfy a following condition: the bypass device and the target operation object affecting data storage are not in a same data storage path and do not act as bypass roles to each other; and wherein updating and correcting, through the bypass device associated with the target operation object affecting data storage, the storage-affecting event record of the target operation object affecting data storage in the affecting event configuration information comprises: in response to that a determination result of the bypass device on the target operation object corresponding to the storage-affecting event record coincides with a result recorded in the affecting event configuration information between the start time of the affecting event and the end time of the affecting event in the storage-affecting event record, indicating that no video storage is performed between the start time of the affecting event and the end time of the affecting event and not needing to update and correct the storage-affecting event record in the affecting event configuration information; and in response to that the determination result of the bypass device on the target operation object corresponding to the storage-affecting event record is contrary to the result recorded in the affecting event configuration information, starting one real data query, taking a query result as a final result, and determining, according to the final result, whether to update and correct the storage-affecting event record in the affecting event configuration information.

2 . The data retrieval prediction method of claim 1 , wherein performing, based on the pre-stored affecting event configuration information, the storage-affecting event analysis on the target operation object through which the data object written from the source end to the destination end passes comprises:
in response to querying that the target operation object exists in the affecting event configuration information, determining a start and end time period of an affecting event of the target operation object recorded in the storage-affecting event record of the affecting event configuration information; and in response to an overlapping time period existing between the start and end time period of the affecting event of the target operation object and the target query time period, predicting abnormal storage of the data object existing in the overlapping time period.

3 . The data retrieval prediction method of claim 1 , wherein a storage-affecting event undergone by the target operation object comprises at least one of a network outage, a power outage, a device offline restart, a service offline restart, or a user operation.

4 . The data retrieval prediction method of claim 1 , further comprising:
in a predicted time period in which concurrent data retrievals do not exceed a threshold, determining, through a data retrieval sampling inspection, a new operation object causing a data storage effect, and forming a new storage-affecting event record and adding the new storage-affecting event record to the affecting event configuration information.

5 . An electronic device applied in a security system, comprising:
at least one processor; and a storage apparatus configured to store at least one program, wherein when executed by the at least one processor, the at least one program causes the at least one processor to perform: determining data storage path information used by a data object in a target query time period; determining, from the data storage path information, a target operation object through which the data object written from a source end to a destination end passes, wherein the target operation object through which the data object written from the source end to the destination end passes comprises at least two of a front-end collection device, a server, a switch device, a storage end device, a storage end device grouping, a disk, an array, a user start-stop storage operation, or an alarm linkage start-stop storage operation; and predicting and determining a storage situation of the data object in the target query time period by performing a storage-affecting event analysis on the target operation object; wherein the at least one program causes the at least one processor to implement predicting and determining the storage situation of the data object in the target query time period by performing the storage-affecting event analysis on the target operation object by: performing, based on pre-stored affecting event configuration information, the storage-affecting event analysis on the target operation object through which the data object written from the source end to the destination end passes; and predicting and determining the storage situation of the data object in the target query time period according to a result of the storage-affecting event analysis on the target operation object, wherein the affecting event configuration information comprises a storage-affecting event record of a data storage effect arising from writing of the data object from the source end to the destination end; and the storage-affecting event record comprises an operation object identifier for affecting data storage, description of an affecting event, start time of an affecting event, and end time of an affecting event; and wherein when executed by the at least one processor, the at least one program causes the at least one pro
