  .SH "DESCRIPTION"

    .PP 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.
    .PP 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 similar fsck or mkfs. For example, for backup/restore hfsplus, just run partclone.hfsp.

  .SH "OPTIONS"

    .PP The program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

      .PP -s FILE, --source FILE

              Source FILE. The FILE could be a image file (made by partclone) or device depend on your action. Normally, backup source is device, restore source is image file.

              Receving data from pipe line is supported ONLY for restoring, just ignore -s option or use '-' means receive data from stdin.

          .RE
          .PP -o FILE, --output FILE

                  Output FILE. The FILE could be a image file (partclone will generate) or device depend on your action. Normally, backup output to image file and restore output to device.

              Sending data to pipe line is also supported ONLY for back-up, just ignore -o option or use '-' means send data to stdout.
