SafeHaven provides a new approach to backup. The basic idea is to store contents away once and forever. No two copies of the same contents will be saved by SafeHaven unless they are presented in two different formats, and even then, SafeHaven attempts to be as smart as possible, and will recognize the most common formats, including compressed files, archives, and ISO image files.
SaraB works with DAR (Disk ARchive) to schedule and rotate backups on random-access media (i.e. hard drives, CDs, DVDs, Zip, or anything else except magnetic tapes). It provides a powerful rotation schedule which allows administrators to create a custom rotation that fits the needs of their network. There is no need to worry about manually rotating, labeling, and properly storing the tapes. It supports the Towers of Hanoi, Grandfather-Father-Son, or any custom backup rotation strategy. It is easy to use and highly configurable.
The purpose of zdisk is to have a kernel of your choice and a rescue system on one floppy or cdrom disk. Zdisk copies a kernel of your choice to a floppy and puts a rescue system on the same floppy, creating a boot/rescue floppy. The kernel can't be more than 1070Kb in size. Ramf-117.exe at the same site has a similar rescue system, except it comes with a IDE kernel.
The dsnapshot script provides a high-level interface to the Linux Logical Volume Manager. It uses its block-level snapshot support to create directory snapshots. In contrast to block-level snapshots, directory snapshots resemble the file system layer. Thus, you can snapshot any directory that is on a logical volume without worrying about the actual logical volumes, mount points, and paths.
