fsarchiver is a system tool that allows you to
save the contents of a filesystem to a compressed
archive file. The filesystem can be restored on a
partition that has a different size, and it can
be restored on a different filesystem. Unlike
tar/dar, fsarchiver also creates the filesystem
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.
