Back up
sudo sfdisk -d [/dev/sdX] > [path/to/file.dump]

说明
sfdisk is a scriptable partition table manipulator. Unlike interactive tools like fdisk, sfdisk is designed for non-interactive use, making it ideal for backup/restore operations and automated partitioning scripts. The dump format is human-readable and can be edited before restoring. This makes it useful for cloning partition layouts between identical disks.
