Need a way to make an image of my HD but compress free space

Specs: Linux x86_64), Intel i7 / 4 GB
I need a software program (preferably free) that I can make an image of my hard drive and have it compress free space. I know of clonezilla. It works great. But I have a 1 TB HD. If I make an image with clonezilla, the image file will be 1 TB. I've used enterprise level imaging programs (Ghost and Acronis) and both of them compress free space. So, if I'm only using 250 GB of my hard drive, the image will be 250 GB and not 1 TB.

I found Aconis True Image where it looks like it backs up your whole hard drive as an image constantly, so if your PC crashed at anytime, you could replace your HD and reload your whole HD as an image quick. But it only works in Windows. I run Linux. Maybe does anyone know of a program like that for Linux?

The reason that cloneziila generates files the same size as the original is in the name. It creates a clone, not an image. A clone is a byte by byte copy of the original so it is identical to the original in every way, including free space. That is what clone means.

Images on the other hand do compress the data. It is not free space they compress, free space is just ignored. It is the data itself that is compressed.

So, do you have a good free image program?

Most cloning software will also create a disk image, it's simply a case of choosing the right part of the program to do the task. There's a free cloning/imaging program here:
