Yes! 'dd' does work. Scrutiniser's 'bs=1M' did the job. A bootable clone in 2.75hours with results returned with no discrepancies.
For your goal IMHO it's better (and easier) to use dd_rescue than dd, even better to use ddrescue. And you learn to use something useful in case of hardware problems (dead sectors). For some more info: System Administration Bits of Knowledge
To install and learn dd_rescue in Ubuntu:
Yes, dd_rescue is in package ddrescue (Debian and Ubuntu).
To install and learn ddrescue in Ubuntu:
Yes, ddrescue is in package gddrescue (Debian and Ubuntu).
For single partitions, best (and often much faster) is to use Partimage.

I am using ufsdump and ufsrestore to clone the root disk on one of my servers. I would like to automate this as much as possible, but have run into a problem where it prompts for changing the owner/mode when it is complete.
Any ideas for running this in the background and not being prompted?

dtc_install_centos(8) System Manager's Manual dtc_install_centos(8)NAME
dtc_install_centos - bootstrap a CentOS install to use in a chroot or VM
SYNOPSIS
dtc_install_centos <install root> <yum environment>
DESCRIPTION
This shell script is part of the dtc-xen package, generally to be used by the dtc panel to install a new a Xen VPS server. This script is
called by dtc_reinstall_os when the user chooses to install the CentOS operating system.
How it works: it generates a temporary yum configuration in the yum environment directory, that directs yum to act inside the install root
instead of in the base system; then it kindly requests yum to install the basesystem, centos-release and yum packages onto it. Yum then
uses the configuration to download the required (usually, security-updated) packages and then perform the RPM installation process under
the install root.
It requires both RPM and yum. It does work under Debian (it was developed in Ubuntu first). It should also work on RPM-based systems
without destroying the system-wide RPM and yum configurations.
OPTION
<install root>
Target directory where CentOS will be deployed. Must exist beforehand.
<yum environment>
Directory where yum will store the repository manifests and configuration. Will be automatically created. Cached RPMs and manifests will
be left, as usual, in a directory var/cache/yum inside the install root.
EXAMPLE
dtc_install_centos /root/yum /xen/13
This will setup the operating system in /xen/13, with the CentOS configuration folder in /root/yum.
BUGS
It's limited to CentOS 5 at the moment.
It must be run as root.
Under some circumstances, the installation process itself may kill processes running on the host machine. The chroot yum does should be
sufficient to avoid this, but we haven't been able, yet, to ascertain why this fails sometimes.
