Here is all you want to know about Clonezilla.http://www.iam.unibe.ch/~spescha/wiki/til/backup_howto
!! Read and see certainly the 'restore-part' of this howto !!
[-When you have for instance a mixed multiboot system with ext3/Grub1 and ext4/Grub2,
-one distro MBR/ext3/Grub1 for the booting (very nice: PCLOS, which has a 'redo-MBR-option' with
adaption of menu.lst),
-and the others pointing to their own root (ext3/Grub1 and/or ext4/Grub2) >>
Clonezilla must not
write Grub in the MBR at the end. In expertmode of Clonezilla
you can configure that. So Clonezilla MBR-restore at the end is o.k. but no Grub-writing in this
special case. If this is not a problem (not multiboot) no problems but read it anyway. ]
When by accident you can't boot anymore use a Berlios Grub/Grub2 Hybrid bootcdhttp://www.supergrubdisk.org/super-grub2-disk/
The cd boots the system or any partition also when the MBR is overwritten, then repair the MBR
with a redo MBR. (Or do it the Grub-way, which is less easy).
(It's a pity there is not a simple
remaster-tool to back up LMDE. Live Magic does not work
right here.) But Clonezilla can do the job.
