The invention discloses a data backup method and device, computer equipment and a readable storage medium. The method comprises the following steps: acquiring a data backup request of a user, whereinthe data backup request of the user refers to one or more data backup requests for the same data file; determining a backup state of a backup task corresponding to the data backup request in a backupqueue; and determining whether to perform deduplication on the backup queue according to the backup state of the backup task in the backup queue. According to the data backup method and device, the technical problem that data storage resources are occupied due to the fact that a plurality of repeated backup files and incomplete backup files existing in the backup system cannot be processed in thedata backup method in the prior art is solved. By means of the data backup method and device, the purpose that only one backup file exists in the same data file in the data storage system is achieved,and therefore, the technical effects of saving data storage space and improving data backup efficiency are achieved.
Description
technical field [0001] The present application relates to the technical field of data backup, in particular, to a data backup method and device, computer equipment, and a readable storage medium. Background technique [0002] Data backup refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. Traditional data backup mainly uses built-in or external tape drives for cold backup. But this method can only prevent man-made failures such as operating errors, and its recovery time is also very long. With the continuous development of technology and the massive increase of data, many enterprises have begun to use network backup. Network backup is generally realized through professional data storage management software combined with corresponding hardware and storage devices. [0003] Usually a single business system ma...
