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.
