dump programs should theoretically take much less time to do
estimates than tar. Tar has to walk the file system directory
tree to discover which inodes to examine taking several steps
to do each inode. That is the reason why DLE's with lots of
small files take so long. OTOH, dump can look directly at
the inode table, determine if the inode is in use or not and
get the relevant info without ever touching a directory tree.
