sdd promises to be like dd though with a progress bar! OLD STUFF FOLLOWS: Brent Wallis recommends: http://www.partimage.org Tim Connors says:
from Brad Hubbard:
sfdisk -l /dev/hda|sfdisk /dev/hdb
Will copy your partitions from /dev/hda to /dev/hdb . In my experience this will work if hdb is bigger but not if it is smaller :-) Bill Farrow uses: At work I use sfdisk to read & write the partion tables. and then a combination of dd, netcat, and gzip to transfer the image over the network to a server. Example:
server> nc -l -p 3000 > hda.sfdisk client> sfdisk -d /dev/hda | nc server_name 3000 server> nc -l -p 3000 > hda.mbr client> dd bs=512 count=1 /dev/hda | nc server_name 3000 server> nc -l -p 3000 > hda1.img.gz client> dd bs=1k if=/dev/hda1 | gzip -c -9 | nc server_name 3000
Then I use “Roll Your Own Linux Rescue or Setup CD” to create a stand alone bootable linux CDROM that automatically dumps the cloned image along with partition and master boot record onto the target machine. The image is gzip’ed up on the bootable CDROM. So if a service tech needs to completely reinstall a machine in the field, they only need one CDROM. Takes all of about 4 minutes to install the OS and then finally boot the new machine. There are a few tricks to minimise the size of the gzip’ed image, and the partition and file system is set up to automatically expand to fill the remaining space on the drive.

dd rsync ghost g4u - ghost for unix (based on netbsd from memory) systemimager
Systemimager looks hopeful. Could not find any “ghost” stuff packaged.
