Is there a command line equivalent to the "disks" utility for disk imaging?

I have recently been using the "disks" utility installed by default on Fedora 17 gnome distributions. I notice it has a "image disk" option.

As I have had a number of file system corruption issues recently combining LUKS, LVM, ext4 and an SSD, I am wondering if this utility has a command line interface so that I can automate backups of my root disk?

I could automate a disk image via dmsetup to take a COW snapshot and dd, but I am wondering if there is an easier solution already in Fedora (my objective is to do this whilst running the system, so that I do not have to boot a live cd, and thus ensure I regularly take snapshots).

Do you have the discard option set for the filesystems on your SSD? If not, it might be the cause of your corruption.

You are probably looking for the dd command.

"but I am wondering if there is an easier solution already in Fedora" - I know what dd is and how to use it already, but thanks anyway :)
