No, you're not.  That's correct.  However, if you have a single 
file system smaller than one tape, that's not a problem.  Also, you 
can use Gnu tar such that you back up directory hierarchies 
separately, and therefore don't need to have the file 
system span tapes.  One tape contains some directories, overflow 
rolls to the subsequent tapes.  

For example, if you have a 100GB fs, and you're using DLT IV tapes 
which only take about 80GB compressed, rather than using dump to dump 
the entire file system, have amanda use gnu tar to dump separate 
directories.  That way you can prune things down to workable sizes.

Most of the people on the amanda-users list do things this way, 
especially since Linus has more than once stated that people 
shouldn't rely upon dump, and that it will someday suddenly disappear.

Geeez!  You want everything! ;)
