3 Free Software Smart Classroom FSSC Free software projects developed by NCHC Free Software Labs Our goal - FSSC (Free Software Smart Classroom) based on HPC (High Performance Computing) experience DRBL, Clonezilla, DRBL-winroll, Tux2live, Partclone Multicast VNC Access Grid, E-learning Cluster computing Grid computing 2008/7/2 page 3

4 DRBL & Clonezilla DRBL Clonezilla (Diskless Remote Boot in Linux) Provides a diskless or systemless environment for client machines A partitioning and disk cloning utility similar to Ghost or True image page 4

5 Bare metal backup and restore Bare-metal restore -> A technique in the field of data recovery and restoration where the backed up data is available in a form which allows one to restore a computer system from "bare metal", i.e. without any requirements as to previously installed software or operating system wikipedia Image-based backup & restore is different from file-based one ('cp', 'tar', 'rsync'...) page 5

6 Clonezilla Features Free (GPL) Software Filesystem supported: ext2/3, reiserfs, reiser4, xfs, jfs, hfs+, FAT and NTFS LVM2 (Linux Logical Volume Manager 2, stackable block device) is supported Multicast is supported in Clonezilla server edition Save and restore not only partitions, but also whole disks If file system is supported, only used blocks in harddisk are saved and restored. For unsupported file system, sector-to-sector copy is done by dd drbl-winroll: the hostname, group, and SID of cloned MS windows machine can be automatically changed. page 6

8 Partclone Developed by Thomas Tsai and Jazz Wang Only used blocks are saved and restored. Supports ext2, ext3, reiserfs, reiser4, xfs, hfs+, fat The next target is to support zfs page 8

26 Testimonial Kristian Hermansen Cisco Systems, Boston, MA, USA. Sep/2007 Clone 5 GB image to 64 machines in 5 minutes "I used Clonezilla in the design of our Cisco Computational Cloud cluster to multicast a 5GB disk image to 64 machines simultaneously. And I did it all in under five minutes! Thanks Clonezilla!!!" page 26

27 Testimonial Barny Sanchez Information Systems Security, Southbridge, Massachusetts, USA. Cloned 1084 systems with DRBL (Clonezilla server edition) "So far I have cloned 1084 systems with DRBL. I followed carefully the advise from the website, and using multicasting plus dividing the amount of systems in groups of PCs at the time, it has taken me somewhere from minutes each turn, using images for various operating systems, averaging 1GB in size. This has reduced the recovery/cloning factor from the previous commercial solution I had, for more than 500%, so you could only imagine how happy my project managers are :-)." page 27
