> Create or Copy blockmaps intelligently (and therefore faster than `cp` or `dd`).
|
||
|
|
|
||
|
|
- Create a blockmap from image file.
|
||
|
|
|
||
|
|
`bmaptool create -o {{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}}`
