PARTCLONE(8) Partclone User Manual PARTCLONE(8) NAME partclone - The utility for clone and restore a partition. SYNOPSIS partclone.[fstype] {[-c | --clone] [-r | --restore] [-b | --dev-to-dev]} {[-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 [-X | --compresscmd] [-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] [-n | --note] [-B | --no_block_detail] [--write-direct-io] [--read-direct-io]] DESCRIPTION partclone.[fstype] is a part of Partclone project. 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, FAT and EXFAT (for Windows), HFS plus (APPLE MAC OS), UFS2 (FreeBSD), VMFS (VMWare Vsphere) and MINIX (MINIX3). All partclone utils could be run like partclone.[fstype] is very smiliar fsck or mkfs. For example, for backup/restore hfsplus, just run partclone.hfsp File System partclone.[fstype] btrfs partclone.btrfs ext2, ext3, ext4 partclone.[ext2 | ext3 | ext4] reiserfs 3.5 partclone.reiserfs reiser 4 partclone.reiser4 xfs partclone.xfs ufs | ufs2 partclone.ufs jfs partclone.jfs hfs plusfs partclone.[hfs+ | hfsplus] vmfs partclone.[vmfs | vmfs5] ntfs partclone.ntfs fat12, fat16, fat32 partclone.[fat12 | fat16 | fat32] exfat partclone.exfat minix partclone.minix f2fs partclone.f2fs nilfs2 partclone.nilfs2 apfs partclone.apfs others (Not Supported FS) partclone.imager 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. -c, --clone Save partition to the special image format. -r, --restore Restore partition from the special image format. -b, --dev-to-dev Local device to device copy on-the-fly, source and output both are 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] -x, --compresscmd CMD Start CMD as an output pipe to compress the cloned image -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 -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. -n, --note NOTE Display Message Note (128 words). -h, --help Show summary of options. -v, --version Show version of program. FILES /var/log/partclone.log The log file of partclone EXAMPLES clone /dev/hda1 to hda1.img and display debug information. partclone.ext3 -c -d -s /dev/hda1 -o hda1.img restore /dev/hda1 from hda1.img and display debug information. partclone.extfs -r -d -s hda1.img -o /dev/hda1 restore image from clonezilla (split, gzip,) with stdin source cat sda1.ext3-ptcl-img.gz.a* | gunzip -c | partclone.ext3 -d -r -s - -o /dev/sda1 DIAGNOSTICS The following diagnostics may be issued on stderr: partclone provides some return codes, that can be used in scripts: Code Diagnostic 0 Program exited successfully. 1 Clone or Restore seem failed.
