Disk imaging program?

[John Hupp]

I'm looking for a freeware disk imaging program that supports/offers:
__ imaging of Windows and Linux partitions in a single image-the-disk 
operation that includes the boot sector and related structures
__ bootable disc can do offline image backup and restore
__ image to spanned DVD’s
__ good compression
__ free for business as well as personal use

Notes on a few of the programs I have considered:

Clonezilla doesn't know how to span to DVD's.

Promising newcomer Aomei Backupper has no stated support for ext4 
partitions.

Redo Backup is a front-end for partclone, and I have seen no 
documentation indicates that it supports spanned DVD's.

In short, everything that I have looked at in the past or now in a fresh 
new sweep falls short on one point or another.

I'm willing to fudge on my desire for a single image-the-disk operation 
if I could find a recipe or documentation on how to use a 
partition-oriented tool with a script that uses several succeeding 
operations to build a complete drive backup. Needless to say, I would 
want to arrive at both backup and restore scripts.
