Manufacture method of recovery disk in computer system

摘要

The disclosed method for manufacturing a recovery disc reduces the size of a recovery program stored on a disc by separately managing the same file among the plurality of recovery programs when the number of recovery programs to be stored on the recovery disc is plural.;When the manufacturing instructions for the recovery disc are input, the recovery programs are judged. When the result of the determination is that there is only one recovery program, the files of the recovery program are stored on the recovery disc, and when there are a plurality of recovery programs, After searching for the same overlapping file among the files of a plurality of recovery programs, save the remaining files except for the overlapping file determined from the plurality of recovery programs on the recovery disk, and the searched overlapped files with the recovery program. It is saved separately in the disk for recovery, and the overlapped file is searched by comparing the file name, size, and contents in order, and the file contents are compared at preset intervals to determine whether they are the same. Save to disk.
