cdrecord can read from a pipe.
The data does not have to be a *.iso file.
dd can get the data back by reading the raw device.
I've burned CDs by cp-ing to the raw device,
but filtering the data through a burner program is probably more reliable.
IIRC I read it back with tar.
Instead of running as root, I changed permissions on the raw device.
OP's simplest solution is probably to use cp
from the raw source disk to a target raw disk.
If reliability is an issue, he can make two copies.
Probably the target could also be a raw USB stick.
Copying entire disks can take a while.
Using a file for a target risks running into file system limitations.
The one that comes to mind is file size limits.
Regardless of how its done,
a cloned drive has the same UUID and partition labels as the original.
