Re: [PLUG] Best tool to image a dynamic disk?

+1 on this.  For LVM, encrypted disks or DRBD work, I use the disk device.

Personally, I like to use the raw disk with LVM. There really is no
need to partition it at all, and it simply adds an unneeded layer and
constraint. Installers often make you think it's required, but it is
not.


Also, dd | netcat to another host is useful as a disk image backup tool
run from a bootable DVD or USB rescue image.
