FSArchiver 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.
