Kleo Bare Metal Backup for Servers is a free file system cloning program created by Carroll-Net Inc. Kleo creates an all-inclusive backup of the operating system, device drivers and applications.
Kleo is bundled with a LiveCD which includes tools for server recovery.
[1] It is designed as a disaster-recovery tool, producing complete file system images.
[4] Unused blocks and empty space are not included which reduces the size of the backup image.
For this reason, they are not suitable replacements for daily backups and are typically only done whenever significant changes are made to a server's application set or prior to applying service patches and hotfixes.
