[0004] Since the files backed up each time are records from the initial time point to the backup time point, the backup files later in time will contain the contents of the image files of all previous backup time points, thus causing the system to back up a large number of With the prolongation of usage time, the later the backup time point, the more duplicate data is backed up, the larger the backup file will be, and the more storage space will be required. Therefore, when backing up the file The longer it takes, the more IO resources it will occupy, and the lower the efficiency will be, which will affect the normal use of the computer.

Embodiment Construction
[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.
[0029] Such as figure 1 As shown, when multiple users use the same operating system, an embodiment of the present invention provides a method for efficiently backing up image files of the operating system, including the following steps:
[0030] S1, make the image file 1.base of the operating system;
[0031] S2, assigning a first-level derivative image file num.a based on the image file 1.base to each user;
[0032] S3, based on the first-level derived image file num.a, a second-level derived image file period.a is derived. Initially, the first-level derived image file num.a and the second-leve...

The invention discloses a method and a system for realizing efficient backup of a mirror file of an operating system, and relates to the field of data storage. The method comprises the steps of S1, making the mirror file of the operating system; S2-S3, deriving two-stage derived mirror files based on the mirror file; S4, recording data of a computer changed within an Nth time period by using the second-stage derived mirror file to form an Nth-time backup file; S5, copying the Nth-time backup file into a backup server, performing naming, and combining the Nth-time backup file with the first-stage derived mirror file in a current storage server; and S6, initializing the second-stage derived mirror file, and repeating the steps S4 to S6, wherein N is a continuous natural number. With the adoption of the scheme, a large amount of repeated data backups are not caused, so that the time for each backup is short, few IO resources are occupied, the backup efficiency is high, and normal use of the computer is not influenced.
Description
technical field [0001] The invention relates to the field of data storage, in particular to a method and system for realizing efficient backup of image files of an operating system. Background technique [0002] In order to ensure that data, especially important data, will not be lost, it is generally backed up regularly. On a traditional physical machine, the operating system is usually backed up to the C drive. With the promotion of virtual machine applications, the operating system has become an ordinary file on the file system for server storage. Therefore, The need to back up the operating system of a computer is also becoming more and more common. [0003] At present, to back up the operating system of a computer, generally all image files of the operating system stored in the current storage server from the initial time point to any backup time point are copied to the backup server. [0004] Since the files backed up each time are records from the initial time point...
