Netcat And DD
Using dd and netcat to clone drives across a network...
To clone a drive on the same machine :
# dd if=/dev/hda of=/dev/hdb
This clones from hda to hdb
To clone onto a different machine
You need a boot disk with netcat and dd on it, along with drivers for any drive controllers and network cards. Then :
1. On the machine you want to clone :
# dd if=/dev/hda conv=sync,noerror bs=64k | nc -l -p 5000
2. On the machine you want to clone to :
# nc <ip of other pc> 5000 | dd of=/dev/hda bs=64k
To clone onto a different machine with compression (for big images...)
1. On the machine you want to clone :
# dd if=/dev/hda conv=sync,noerror bs=64k | gzip -c | nc -l -q 0 -p 5000
2. On the machine you want to clone to :
# nc 192.168.1.1 5000 | gzip -cd | dd of=/dev/hda bs=64k
