说明
partclone creates and restores partition images while skipping empty blocks, resulting in smaller backup files and faster operations compared to raw disk imaging. Each filesystem type has its own binary that understands the filesystem structure. The tool reads only used blocks from the source filesystem, making backups significantly smaller than the partition size. This is especially beneficial for partially filled partitions.
