What can I use to create a backup image of my entire system that will be saved on a LAN computer via SSH? If I break anything later, I want to be able to restore my entire system as it was before the backup in minutes. Is there a Live CD that can "save backup image to ssh://..." and "restore from backup image ssh://..."?
Tell me more

Clonezilla would be a suitable product for a whole-disk image. It works in a fashion similar to Ghost. |

Acronis True Image is a possible solution. But If you want to, you can also use the command-line: On the receiver side:

ddimage of your /dev/sda. This will include the bootsector and will therefore recover the whole system. It is a lengthy process though. You should specify more details about what you are trying to do and why you think you need it. – jippie May 28 '12 at 18:26ddis far from ideal, particularly if you dd an entire drive; it's tricky to get single files out of it (which is a much more common restore scenario in practice than starting over from a clean slate), it's slow, plain dd uses excessive amounts of disk space due to its bit-by-bit copying, and for it to work well on restore, you need a drive of the exact same size as the original. Better to copy the files andddthe boot sector and boot loader part of the MBR if you can't be bothered to typegrub-install '(sd0)'. – Michael Kjörling May 29 '12 at 9:56
