Abstract

The invention provides a mirror image file processing method and device. The mirror file processing method includes: determining if a target storage library includes a mirror image file having the same mirror identifier as a designated mirror image file to be copied or not; and giving up an operation for copying the designated mirror image file from a source storage library to the target storage library if the determination result is yes. The mirror image file processing method and device can solve the problem that the identical mirror image files are recopied, and storage resources are wasted in the prior art.

Description

technical field [0001] The invention relates to the field of file processing, in particular to a method and device for processing mirror images. Background technique [0002] In a virtualization scenario, multiple storage repositories are generally created, and all virtual machine disk files are created on these storage repositories. When the storage repository is full or required by business management, some virtual machines must be migrated to other storage repositories. Generally speaking, you can directly copy the disk files of the virtual machine to the target storage. But in this way, if the disks of two virtual machines share a parent node file, if they are all migrated to the same storage repository, there will be a phenomenon that one source file will generate multiple target copies. [0003] Facing the above-mentioned problems existing in related technologies, no effective solution has been found yet. Contents of the invention [0004] The present invention pr...
