SHOUT! I'm not certain of the insides of duplicity, but I understand it, 
and as my experience with duplicity shows:

Because it use librsync, large files that change only little lead to 
small backups, irrespective of inode or whatever.

Perhaps the mysqldump output contains many timestamps or other things, 
that make these large files very different. But if they're similar, that 
should lead to small incremental backups.
