PARTCLONE.DD(8) Partclone User Manual PARTCLONE.DD(8) NAME partclone.dd - unsupported file system backup utility.(like `dd` ) SYNOPSIS partclone.dd {[-s | --source] source} {[[-o | --output] [-O | --overwrite]] target} [[-dX | --debug=X] [--restore_raw_file] [-z | --buffer_size] [-N | --ncurses] [-q | --quiet] [-f | --UI-fresh] [-F | --force] [-I | --ignore_fschk] [-i | --ignore_crc] [-C | --nocheck] [-R | --rescue] [-L | --logfile] logfile [-R | --rescue] [-L | --logfile] logfile [-D | --domain] [--offset_domain] [-aX | --checksum-mode=X] [-kX | --blocks-per-checksum=X] [-K | --no-reseed] [-w | --skip_write_error] [-E | --offset=X] [-T | --btfiles] [-t | --btfiles_torrent] [-B | --no_block_detail] [--binary-prefix] [--prog-second] [--write-direct-io] [--read-direct-io]] 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. OPTIONS The program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -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. -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. -O FILE, --overwrite FILE Overwrite FILE, overwriting if exists. -W FILE, --restore_raw_file FILE create special raw file for loop device. -D, --domain Create GNU Ddrescue domain log file from source device. This is a human readable file in which + marks used block areas and ? marks free areas. --offset_domain=X Add X (in bytes) to all positions reported in the domain log file --restore_raw_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, --ncurses Using Ncurses Text User Interface. -I, --ignore_fschk Ignore filesystem check. -i, --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. -dlevel, --debug level Set the debug level [1|2|3] -aX, --checksum-mode=X Checksum formula to use to add error detection where X: 0: No checksum (no slowdown, smallest image) 1: CRC32 (Fast to compute, basic detection) -kX, --blocks-per-checksum=X Write one checksum for every X blocks -w, --skip_write_error Continue restore while write errors --write-direct-io Writing data to TARGET partition without cache --read-direct-io Reading data from SOURCE partition without cache -B, --no_block_detail Show progress message without block detail --binary-prefix Show progress with bit size (default is MB, GB...) --prog-second Show progress in seconds (default is minute) -E, --offset=X Add offset X (bytes) to OUTPUT -T, --btfiles Restore block as file for ClonezillaBT. -t, --btfiles_torrent Restore block as file for ClonezillaBT but only generate torrent. -h, --help Show summary of options. -v, --version Show version of program. FILES /var/log/partclone.log The log file of partclone.dd 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 DIAGNOSTICS The following diagnostics may be issued on stderr: partclone.dd provides some return codes, that can be used in scripts: Code Diagnostic 0 Program exited successfully. 1 Clone or Restore seem failed.
