Abstract: The present application provides a data processing method and apparatus. The method includes: when a region in a table of a database system meets a predefined condition, saving data in the region as a data storage file to a storage device, where the data storage file includes time metadata, and the time metadata comprises a region write time of the data in the region; when a condition for triggering a combination operation is met, obtaining a time for performing a backup operation most recently; selecting at least two first data storage files, where a region write time recorded in time metadata included in the at least two first data storage files is before the obtained time; and combining the selected at least two first data storage files, therefore resolving a problem in the prior art that a time consumed for performing a backup operation is long.

Abstract: A method for updating a data table in a KeyValue database is provided. Raw data is received and formatted into a data updating file. An update timestamp is set for each column qualifier in each row of the data updating file. A data deleting file is generated. A delete timestamp is set for each row of the data deleting file. Each row of the data deleting file corresponds to one row of old data in the data table. Each row of the data deleting file includes a row key that is the same as the row key of the corresponding row of old data in the data table. The data updating file and the data deleting file are both imported into the data table. Consequently, timestamp is used to indicate the valid data in the data table. An apparatus configured to perform the method is also provided.

Abstract: A data backup method and a data processing system are provided. The method includes: when a quantity of storage files stored in a storage medium meets a preset threshold, acquiring storage files which are stored in the storage medium after a time point, where the time point is a time of previously backing up storage files in the storage medium; combining the storage files after the time point to obtain at least one new storage file; and backing up the at least one new storage file. Therefore, incremental backup is performed on the storage files after the time point.
