Abstract
Aspects of this disclosure provide a data backup method and apparatus, a server, and a non-transitory computer-readable storage medium, belonging to the field of data database technologies. The method can include receiving a backup task that is used for backing up a data item of a target data table. The method can further include obtaining a first snapshot difference between a first historical transaction snapshot and a second historical transaction snapshot when a backup time of the backup task is a historical time period. The first historical transaction snapshot and the second historical transaction snapshot can be transaction snapshots respectively located at a start moment and an end moment of the historical time period. Additionally, the method can include performing the backup task based on the first snapshot difference to obtain backup data including at least a visible version of the data item in the target data table.
