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

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

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. 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.
-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
Add X (in bytes) to all positions reported in the domain log 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 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]
-h, --help
Show summary of options.
-v, --version
Show version of program.
