I just dropped in on this thread about Amanda.  I'm currently looking
for a backup to disk solution for a new system and am curious how well
Amanda would work.  I've got a large raid partition that I want to
backup onto a removable hard drive.  The tricky part is that the
filesystem is made up of over a million tiny (2-3k) files.  Would
Amanda be able to deal with that type of filesystem?
