## DESCRIPTION

`&dhpackage;` 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.

## OPTIONS

`-s `FILE``

`--source `FILE``

`-o `FILE``

`--output `FILE``

- Output FILE. The FILE could be a image file(partclone will generate) or device depend on your action. Normanly, 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.

`-O `FILE``

`--overwrite `FILE``

- Overwrite FILE, overwriting if exists.

`--restore_row_file`

- Creating special raw file for loop device.

`-l `FILE``

`--logfile `FILE``

- put special path to record partclone log information.(default /var/log/partclone.log)

`-R`

`--rescue`

- Continue after disk read errors.

`-C`

`--no_check`

- Don't check device size and free space.

`-N`

`--ncurse`

- Using Ncurses Text User Interface.

`-X`

`--dialog`

- Output message as Dialog Format.

`-I`

`--ignore_fschk`

- Ignore filesystem check.

`--ignore_crc`

- Ignore crc check error.

`-F`

`--force`

- Force progress.

`-f `sec``

`--UI-fresh `sec``

- put special second to different interval.

`-z `size``

`--buffer_size `size``

- Read/write buffer size (default: 1048576)

`-q`

`--quiet`

- Disable progress message.

`-d`level``

`--debug `level``

- Set the debug level [1|2|3]

`-h`

`--help`

- Show summary of options.

`-v`

`--version`

- Show version of program.

## FILES

`/var/log/partclone.log`

- The log file of &dhpackage;

## EXAMPLES

     clone /dev/hda1 to hda1.dd.img and display debug information.
       partclone.dd -d -s /dev/hda1 -o hda1.dd.img

     restore /dev/hda1 from hda1.dd.img and display debug information.
       partclone.dd -d -s hda1.dd.img -o /dev/hda1
