Clonezilla

Si alguna vez probaste Norton Ghot un programa para backups completos del sistema operativo (windos o linux) seguro que tambien conoces Clonezilla, acaba de actualizarse con algunas caracteristicas mas.
Su manejo es bastante sencillo, solo crearemos un pendrive de arranque (aconsejo crearlo con un arranque de windows) arrancamos el sistema desde el pendrive y seguimos las instrucciones, podemos hacer backup de particion a particion, de disco a disco o de particion a otra particion de un segundo disco.

Features:

• Free (GPL) Software.
• Filesystem supported: (1) ext2, ext3, ext4, reiserfs, reiser4, xfs, jfs, btrfs of GNU/Linux, (2) FAT12, FAT16, FAT32, NTFS of MS Windows, (3) HFS+ of Mac OS, (4) UFS of FreeBSD, NetBSD, and OpenBSD, (5) minix of Minix, and (6) VMFS3 and VMFS5 of VMWare ESX. Therefore you can clone GNU/Linux, MS windows, Intel-based Mac OS, FreeBSD, NetBSD, OpenBSD, Minix and VMWare ESX, no matter it's 32-bit (x86) or 64-bit (x86-64) OS. For these file systems, only used blocks in partition are saved and restored. For unsupported file system, sector-to-sector copy is done by dd in Clonezilla.
• LVM2 (LVM version 1 is not) under GNU/Linux is supported.
• Boot loader, including grub (version 1 and version 2) and syslinux, could be reinstalled.
• Both MBR and GPT partition format of hard drive are supported. Clonezilla live also can be booted on a BIOS or uEFI machine.
• Unattended mode is supported. Almost all steps can be done via commands and options. You can also use a lot of boot parameters to customize your own imaging and cloning.
• One image restoring to multiple local devices is supported.
• Multicast is supported in Clonezilla SE, which is suitable for massively clone. You can also remotely use it to save or restore a bunch of computers if PXE and Wake-on-LAN are supported in your clients.
• The image file can be on local disk, ssh server, samba server, or NFS server.
• Based on Partclone (default), Partimage (optional), ntfsclone (optional), or dd to image or clone a partition. However, Clonezilla, containing some other programs, can save and restore not only partitions, but also a whole disk.
• By using another free software drbl-winroll, which is also developed by us, the hostname, group, and SID of cloned MS windows machine can be automatically changed.

Minimum System Requirements for Clonezilla live:

• X86 or x86-64 processor
• 196 MB of system memory (RAM)
• Boot device, e.g. CD/DVD Drive, USB port, PXE, or hard drive

Limitations:

• The destination partition must be equal or larger than the source one.
• Differential/incremental backup is not implemented yet.
• Online imaging/cloning is not implemented yet. The partition to be imaged or cloned has to be unmounted.
• Software RAID/fake RAID/firmware RAID is not supported by default. It can be done manually only.
• Due to the image format limitation, the image can not be explored or mounted. You can _NOT_ recovery single file from the image. However, you still have workaround to make it, read this.
• Recovery Clonezilla live with multiple CDs or DVDs is not implemented yet. Now all the files have to be in one CD or DVD if you choose to create the recovery iso file.
