man fstab

        The  fifth field, (fs_freq), is used for these filesystems
        by the dump(8) command to determine which filesystems need
        to  be dumped.  If the fifth field is not present, a value
        of zero is returned and dump will assume that the filesys-
        tem does not need to be dumped.

So, a value of 0 means don't backup this filesystem.  Values larger than 0 
should cause dump to perform backups of that filesystem.  Reasons for this is 
that you might have automated scripts that do full or incremental backups 
shouldn't backup unneeded filesystems (like if /var was a ramdisk image, or /tmp).
