[edit] Recovery tools

Here is a short description of some of the system tools.

FSArchiver [2]
it's a flexible system tool that allows you to save the contents of a file-system to a compressed archive file. The file-system can be restored on a partition which has a different size and it can be restored on a different file-system. It provides multi-threading compression and supports lzma compression (very high compression level) as well as lzo, gzip and bzip2. Everything is checksummed in the archive in order to protect the data. It supports all the linux-filesystems including ext4, and also it can be used to clone ntfs partitions.
Partimage [3]
Save/restore hard disk partitions and MasterBootRecord to/from a compressed image file locally or over the network to another computer. Save partitions when system is working, like after an install or upgrade or like right now! Then restore them after the system gets corrupted or disk failure without having to reinstall and configure the OS and all the other packages.
