Abstract: An operating method of a backup device includes displaying a window corresponding to a backup destination on a graphic user interface (GUI); under a condition that an add-into-backup-list command is received via the GUI, recording a first backup entry corresponding to backup target data by a backup list according to the add-into-backup-list command; after the first backup entry is recorded, displaying an icon corresponding to the first backup entry in the window corresponding to the backup destination; and under a condition that a start-backup command is received via the GUI, backing up the backup target data into the backup destination according to the start-backup command.

Abstract: A tool pan has a number of homocentric annular structures which have rubbing zones. Provided between the contiguous rubbing zones is at least a ramp, which is extending along the normal of the tool pan, and the height of which is increased gradually towards the fringe of the tool pan. In a rubbing machine the tool pan is used. The rubbing machine is applicable in paper making industry, and can effectively separate and fibrillate the fiber of herbage by mechanical force between a pair of tool pans, thereby needing not to use chemicals, and according with the modern conception of environmental protection.

Abstract: A rubbing machine and its tool pan are disclosed. The tool pan (122) comprises a number of homocentric annular structures (125) which have a lot of rubbing zones (121). Provided between the contiguous rubbing zones is at least a ramp (127), which is extending along the normal of the tool pan, and the height of which is increased gradually towards the fringe of the tool pan. In the rubbing machine (100) the tool pan is used. The rubbing machine is applicable in paper making industry, and can effectively separate and fibrillate the fiber of herbage by mechanical force between a pair of tool pans, thereby needing not to use chemicals, and according with the modern conception of environmental protection.
