6-1. OS Backup Button:
When pushing the OS backup button, the system will display the indication message (remark 1). After
pressing the "OK" button, the system will end Windows automatically and restart to DOS (remark 2), backing
up the OS of the hard disk together with the data of the system disk. (remark3)(remark4)
If the used disk space of the system disk is larger than the free disk space of the USB HDD, the backup will
fail due to insufficient disk space. We suggest you delete unnecessary files so that the free disk space of the
USB HDD is larger than or equal to the used space of the system disk.
