PURPOSE:To prevent the error of backup copying by checking the coincidence of the document control information of a copy destination recording medium and a copy source recording medium up to the recorded final document of the copy destination recording medium, and carrying out copying. CONSTITUTION:The coincidence of the recording medium control information of the copy destination recording medium and the copy source recording medium, and the coincidence of the document control information of the copy destination recording medium and the copy source recording medium up to the recorded final document of the copy destination recording medium are checked, the copying of the document of a terminal copy is carried out. That is, when the master recording medium is erroneously set as the copy destination recording medium, since identifying information for the backup is not recorded, the copying is not carried out, and when the recording medium for the backup uncorresponding to the copy source recording medium, although whose recording medium control information conforms to each other, or the recording medium for the backup to which additional recording is erroneously carrier out is set as the copy destination recording medium, since the comparison between document control information is made inconsistent, the copying is not carried out. Thus, the error of the backup copying can be prevented. |
