PING (Partimage Is Not Ghost) is a free software Linux-based live CD ISO built upon the partimage and Linux from Scratch (LFS) projects for disk cloning or backup purposes. The software supports most hardware platforms using ATA, SATA, or SCSI systems for desktop computers, workstations, and servers. It can access file systems using FAT16, FAT32, NTFS or ext3 format. Since PING is built upon LFS, it is very small in size. Even if a user decided to expand the content and install it permanently on hard drive, it would still take only 20 MB.
