bmaptool Command Examples

Create or copy block maps intelligently (designed to be faster than cp or dd). More information: https://manned.org/bmaptool.

• Output a blockmap file from image file:

bmaptool create {{[-o|--output]}} {{blockmap.bmap}} {{source.img}}

• Copy an image file into sdb:

bmaptool copy --bmap {{blockmap.bmap}} {{source.img}} {{/dev/sdb}}

• Copy a compressed image file into sdb:

bmaptool copy --bmap {{blockmap.bmap}} {{source.img.gz}} {{/dev/sdb}}

• Copy an image file into sdb without using a blockmap:

bmaptool copy --nobmap {{source.img}} {{/dev/sdb}}
