NAME
       btrfs-image - create/restore an image of the filesystem

SYNOPSIS
       btrfs-image [options] source target

DESCRIPTION
       btrfs-image  is used to create an image of a btrfs filesystem. All data
       will be zeroed, but metadata and the like is preserved.	source is  the
       special file corresponding to the device containing a btrfs filesystem.
       (e.g /dev/sdXX).	 target is the image file  that	 btrfs-image  creates.
       When  used  with	 -r  option,  btrfs-image restores the image file from
       source into target.

OPTIONS
       -r     restore metadump image.

       -c value
	      compression level (0 ~ 9).

       -t value
	      number of threads (1 ~ 32) to be used to process the image  dump
	      or restore.

       -o     use  the	old restore method, this does not fixup the chunk tree
	      so the restored file system will not be able to be mounted.

AVAILABILITY
       btrfs-image is part of btrfs-progs.  Btrfs  is  currently  under	 heavy
       development,  and not suitable for any uses other than benchmarking and
       review.	Please refer to the  btrfs  wiki  http://btrfs.wiki.kernel.org
