.SH "DESCRIPTION"
.PP
\fBpartclone\&.dd\fR
is a part of
\fBPartclone\fR
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\&.
.PP
\fBPartclone\fR
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\&.
