Clonezilla – One Partition and disk cloning program to rule them all
Clonezilla is a partition and disk imaging/cloning program similar to True Image and Norton Ghost. I frequently use Clonezilla software to do system deployment, bare metal backup and recovery. Clonezilla live is good for single machine backup and restore at home. Clonezilla SE is for massive deployment in data center, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. It supports the following file systems
ext2, ext3, ext4, reiserfs, xfs, jfs of GNU/Linux
FAT, NTFS of MS Windows
HFS+ of Mac OS
UFS of BSD
minix of Minix and VMFS of VMWare ESX.

Solo con acceso SSH:
ssh al sistema remoto y termine todos los procesos que pueda. Basically everything but the ssh server itself.
Desde su sistema local, capture una copia de una imagen del disco a su sitema local:
ssh root @ remote .example .com "dd if=/dev/sda bs=1024k" > p2v .img
Espera muchas horas. Depende del tamaño del disco duro y el ancho de banda.
Finalizara con un archivo llamado p2v.img. Montelo a una KVM virtual machine como raw disk image y fsck y encuentra errores.
Si tiene acceso al servidor
From the remote console, bring the system to single-user mode (init 1 as root, or reboot with 1 added to the boot command line).
Bring up the network manually, e.g. with the appropriate ifconfig and route commands.
P2V it to the remote hypervisor (or a storage server):
dd if = / dev / sda bs = 1024k | ssh root @ kvmhost .example .com "cat > /path/to/p2v.img"
Create a new KVM virtual machine using p2v.img as the disk, start it up and make any necessary changes.
