info about fsarchiver
One free tool you can use for this is [fsarchiver], which <<is a 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. Unlike tar/dar, FSArchiver also creates the file-system when it extracts the data to partitions. Everything is checksummed in the archive in order to protect the data. If the archive is corrupt, you just loose the current file, not the whole archive. Fsarchiver is released under the GPL-v2 license. It's still under heavy development so it must not be used on critical data.>>, So, you've been warned. Latest fsarchiver should be in the latest [SystemRescueCD], although you can obtain it on your favourite recent distribution.
