Incremental backup method of database, readable storage medium and computer equipment

The invention provides an incremental backup method of a database, a readable storage medium and computer equipment wherein the method comprises: in response to a data backup instruction for backing up the database, obtaining a target value of the database wherein the target value is at least reflected after a set historical moment, and sending the target value to the computer equipment; the file number and the data volume of data are updated in the database; determining an incremental backup strategy according to a relative relationship between the target value and a preset threshold value; wherein the incremental backup strategy is one of a block incremental backup strategy and a file incremental backup strategy; and executing the incremental backup strategy to generate an incremental backup set. According to the technical scheme, the problem that the application scene and the incremental backup strategy are not matched in the database operation process in the prior art can be solved, and the purpose of imp
