Dump/restore are filesystem specific.  This can be a good
reason to avoid them.  Have multiple systems that can
read your data is a nice convenience.

I'd vote for cpio output by scripts or amanda.

The suggestion to use a list of filesystems to backup
is bad.  Use a list of filesystems to avoid backing up.
Write your script to backup everything except specified
directories (/proc /tmp).  Then when filesystems are
created years from now they will automatically be backed
up.
