It's a bit dated (1991) but still a good read: http://reality.sgi.com/zwicky_neu/testdump.doc.html In practice, the differences between dump and tar are miniscule. The main difference is that tar works on files, whereas dump works on the underlying filesystem. This means that dump will only work on ufs filesystems. If you are looking to backup a filesystem over samba/nfs, then dump won't work. I personally use dump, wherever possible. -Paul.
