Problems solved by technology

However, the existing synthetic backup needs to obtain non-expired data files from the full backup and incremental backup, and then write the obtained non-expired data files into the synthetic backup file one by one, that is, it is necessary to move the full backup and the incremental backup. data files in incremental backups, which greatly increases the operation time of synthetic backups and reduces the efficiency of synthetic backups

Embodiment Construction

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] See figure 2 , figure 2 This is a synthetic backup flowchart provided by an embodiment of the present invention. Such as figure 2 As shown, the process can include the following steps:

[0035] Step 201: Determine an unexpired data file from incremental backup files to be synthesized currently stored in the storage medium.

[0036] Here, the unexpired data file in the incremental backup file is the file with the latest data content, see Figure 3a , Figure 3a This is a schematic diagram of the incremental backup currently stored in the storage medium in this embodiment, such as Figure 3a As shown, the incremental backup file currently stored in the storage medium includes incremental backup file 1 and incremental backup file 2, where file ...

Abstract

The invention provides a method and a device for synthetic data backup, wherein the method comprises: confirming unexpired data files from incremental backup files to be synthesized which are stored by a storage medium currently; and storing the confirmed unexpired data files to full backup file stored by the storage medium. In the invention, only unexpired data files in the incremental backup files stored by the storage medium can be moved, while the data files in the full backup file are not moved, thereby reducing the amount of movement of the data files, greatly reducing the operating time of the synthetic backup, and improving the performances of the synthetic backup.

Description

technical field [0001] The invention relates to data backup technology, in particular to a synthetic data backup method and device. Background technique [0002] Data backup is currently the most commonly used solution to prevent data loss. Its basic principle is to provide redundant storage for data files stored in the computer system. When the original data files in the computer system are due to hardware failure, software failure or user When the data file is lost due to misoperation or other reasons, the data file can be recovered from the redundant storage, thus providing effective protection for the data file stored in the computer system. [0003] With the popularity of computers, the network backup system has been developed due to the advantages of centralized and unified backup management for a group of computers. In the network backup system, two backup methods are usually provided, one is full backup; the other is incremental backup. Among them, the full backup...
