pv method

You could use pv (man page) utility like so:

Code:
sudo sh -c 'pv < /dev/sda > /destination'
Of course you could become root first:

sudo -i

And then just do the backup:

Code:
pv < /dev/sda > /BackupDestination
And then when needed do the restore:

Code:
pv < /BackupDestination > /dev/sda
pv works similar to the dd command but is a little faster and it shows the progress
