Mirror image storage method, mirror image generation method and mirror image generation system

The invention discloses a mirror image storage method, generation method and system, and the generation method comprises the steps: obtaining a to-be-written mirror image file in a target cloud environment and the description information of the mirror image file through a mirror image generation platform; obtaining configuration information of a mirror image import API, and generating a mirror image import program of the mirror image data packet according to the configuration information of the mirror image import API; the mirror image import program is used for calling the mirror image import API in the target cloud environment to write the mirror image file; and generating the mirror image data packet according to the mirror image import program, the mirror image file and the description information, so that the mirror image data packet can be automatically generated, the cost and the error rate of human intervention are reduced, and meanwhile, the user experience is improved.
