 Partclone is a project developed by NCHC as a replacement to partimage and is the default imaging system used by Clonezilla. It has support for many more filesystems, though ext2, ext3, ext4, hfs+, reiserfs, reiser4, btrfs, vmfs3, vmfs5, xfs, jfs, ufs, ntfs, fat(12/16/32), exfat.
 
-Ntfsclone for the purpose of this analysis I didn't look into ntfsclone too much. As the name suggests, it only supports cloning ntfs.

 dd is exactly what you’d expect, it simply runs dd on the partition and writes it to a file.  The file is generally gzipped to save some space, though it still ends up being very large. Since the above systems support most of the common file system formats dd is rarely used, though it is available if a partition’s file system is unsupported.

 === Performance Numbers ===
 
-In order to test potential performance of Clonezilla in comparison to the current frisbee system I created a deter experiment for testing each. The Clonezilla experiment used three Ubuntu machines with one server imaging two clients while the frisbee experiment used three FreeBSD 9 machines running frisbee (this is due to the fact that while Frisbee’s imagezip and imageunzip programs can be compiled and run on Linux, Frisbee's frisbee client can only run under FreeBSD).

-I also eliminated the DRBL part of Clonezilla from the experiment since getting nodes to PXE boot properly from within a DeterLab experiment is very difficult since the Deter system itself has is also serving PXE images to the node in order to actually allow the system to operate. For that reason testing on the Clonezilla side of things only involved using udpcast on the nodes and piping the outputs to the different available image restoration programs and timing how long this took.

+The tcl file for the Clonezilla experiment looks like this:
+{{{
+source tb_compat.tcl
+set ns [new Simulator]
+
+# crate new nodes. the default image is 64-bit Ubuntu
+set server [$ns node]
+set client1 [$ns node]
+set client2 [$ns node]
+
+set lan0 [$ns make-lan "$server $client1 $client2" 1000Mb 0ms]
+
+$ns run
+}}}
+
+For testing purposes the [https://www.emulab.net/downloads/images-STD/UBUNTU12-64-STD.ndz UBUNTU12-64-STD] emulab image was used. Using imagezip we put it on /dev/sda4 on an experimental node and create a parclone and partimage image out of it.
+
+Similarly we tested frisbee from three FreeBSD nodes using the same technique:
+
+{{{
+source tb_compat.tcl
+set ns [new Simulator]
+
+set server [$ns node]
+set client1 [$ns node]
+set client2 [$ns node]
+
+tb-set-node-os $server FBSD9-64-STD
+tb-set-node-os $client1 FBSD9-64-STD
+tb-set-node-os $client2 FBSD9-64-STD
+
+set lan0 [$ns make-lan "$server $client1 $client2" 1000Mb 0ms]
+
+$ns rtptoto Static
+$ns run
+}}}
