cpio is more robust than tar, i.e. it is easier to recover from an error
in the archive. I tend to use cpio when I want to copy the contents of a
directory structure from one place to another and keep all ownership and
permissions intact on the files and directories copied.


/home is getting full, you have a new partition ready. mounted on /mnt
where all the data is being copied to.

cd /home ; find . | cpio -pdumvB /mnt

When command completes, you have a perfect copy of /home in /mnt.

man page should give some idea about what cpio is capable of. If that is
not enough, a few searches on google should give more details. cpio is
frequently used for backing systems up to tape, like tar, dump and
backup is.
