Clonezilla


clonezilla

Clonezilla is a partition and disk imaging/cloning program similar to True Image® or Norton Ghost®. It helps you to do system deployment, bare metal backup and recovery. Two types of Clonezilla are available, Clonezilla live and Clonezilla SE (server edition). Clonezilla live is suitable for single machine backup and restore. While Clonezilla SE is for massive deployment, it can clone many (40 plus!) computers simultaneously. Clonezilla saves and restores only used blocks in the harddisk. This increases the clone efficiency. At the NCHC’s Classroom C, Clonezilla SE was used to clone 41 computers simultaneously. It took only about 10 minutes to clone a 5.6 GBytes system image to all 41 computers via multicasting!

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.
