Abstract

The embodiment of the present invention discloses a mirror image data transmission method, which includes the following steps: acquiring bitmaps corresponding to multiple mirror image files, wherein the bitmap is used to identify whether mirror data is written into the corresponding position of the mirror image files; The bitmap corresponding to the image file generates a corresponding merged bitmap; according to the merged bitmap, reads the mirrored data from the corresponding positions of the multiple mirrored files, and transmits the read mirrored data. The embodiment of the invention also discloses a mirror image data transmission device, mirror image data transmission equipment and a computer-readable storage medium. The embodiment of the present invention improves the backup efficiency of the virtual machine.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a mirror image data transmission method, device, equipment, and computer-readable storage medium. Background technique [0002] The backup of a virtual machine is generally the first full backup, followed by continuous incremental backups. Full backups and incremental backups are independent image files. In scenarios such as (cloud) archiving and (cloud) disaster recovery, it is necessary to Files are transmitted to different places one by one through the network, which takes a long time. Moreover, because the same image data exists in different image files, these same image data have the problem of repeated transmission. In summary, the backup efficiency of virtual machines is low. . Contents of the invention [0003] The main purpose of the embodiments of the present invention is to provide a method, device, device, and computer-readable s...
