Mirror image file management method and device, computer equipment and storage medium

The invention discloses a mirror image file management method and device, computer equipment and a storage medium, and relates to the technical field of servers, and the method comprises the following steps: obtaining a file operation instruction and target file information; determining a file ID corresponding to the target file information by using a character string list according to the target file information; determining file information corresponding to the file ID according to the file ID, and operating the file information according to the file operation instruction; mirror image file management can be achieved only in a single transmission mode, the implementation method is simple, the transmission speed is high, and before each time of reading and writing, a character string list, namely runtime information, needs to be obtained from a BMC external file system, so that the situation that when a mirror image system and a BMC need to reserve a large amount of runtime information, one end is restarted,
