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 lose the current file, not the whole archive.
