My (vague, unsophisticated) understanding is that mysqlhotcopy makes a
copy of the raw data files. I'll note that I don't know whether or not
it even works with InnoDB.

mysqldump, on the other hand, outputs valid SQL which recreates the database.

BTW, if you think mysqldump is running slow, wait until you try
restoring that dump. At 33 hours or so for a backup, it might take you
more than a week to restore, depending on the options you gave
mysqldump for building the output.
