Clonezilla Live Stable and Testing
"The DRBL-based PXEBoot Clonezilla is used to clone many computers simultaneously. It is an extremely useful tool, however, it does have several limitations. In order to use it, you must first prepare a DRBL server AND the machine to be cloned must boot from a network (e.g. PXE/Etherboot). To address these limitations, the Free Software Lab at the NCHC has combined Debian Live with Clonezilla to produce "Clonezilla Live," a new software that can be used to easily clone individual machines.
The primary benefit of Clonezilla Live is that it eliminates the need to set up a DRBL server ahead of time and the need for the computer being cloned to boot from a network. Clonezilla Live can be used to clone individual computers using a CD/DVD or USB flash drive. Though the image size is limited by the boot media's storage capacity, this problem can be eliminated by using a network filesystem such as sshfs or samba. ///Note/// PXEBoot Clonezilla should still be used to clone many computers simultaneously. [...]
Clonezilla, based on DRBL, Partition Image, ntfsclone, and udpcast, allows you can massively clone many (40 plus!) computers simultaneously. Unlike G4U (Ghost for Unix) or G4L (Ghost for Linux), Clonezilla saves and restores only used blocks in the harddisk. This increases the clone effiency. At the NCHC's Classroom C, Clonezilla was used to clone 41 computers simultaneously. It took about 50 minutes to clone a 5.6 GBytes system image to all 41 computers via unicasting and only about 10 minutes via multicasting!"
