DESCRIPTION

       partclone.dd is a part of Partclone project to clone unsupported file system with dd
       method. It will backup all block from partition. Partclone provide utilities to backup
       used blocks and design for higher compatibility of the file system by using existing
       library, e.g. e2fslibs is used to read the used block of ext2 partition.

       Partclone supported file system include btrfs, ext2, ext3, ext4, reiserfs, reiser4, xfs
       and jfs for LINUX. Also support some non-linux operation system, ex: NTFS and FAT (for
       Windows), HFS plus(APPLE MAC OS), UFS2(FreeBSD), VMFS(VMWare Vsphere). All partclone utils
       could be run like partclone.xxx is very smiliar fsck or mkfs. For example, for
       backup/restore hfsplus, just run partclone.hfsp.
