sudo sh -c 'pv < /dev/sda > /destination'
sudo -i
pv < /dev/sda > /BackupDestination
pv < /BackupDestination > /dev/sda

Desde un USB live con linux:
dd if=/dev/sda of=/somewhere/file.mbr bs=512 count=63
dd if=/dev/sda1 bs=1M status=progress | lz4 > /somewhere/sda1.lz4
dd if=/dev/sda2 bs=1M status=progress | lz4 > /somewhere/sda2.lz4
dd of=/dev/sda if=/somewhere/file.mbr
Ahora restaure las dos particiones de Windows.
dd of=/dev/sda1 bs=1M status=progress < lz4cat /somewhere/sda1.lz4
dd of=/dev/sda2 bs=1M status=progress < lz4cat /somewhere/sda2.lz4
bootrec /fixmbr
La solución más fácil es: dd if=/dev/sda of="/media/usb/$(date).img" pero es muy lento.
