svnadmin help text clearly states that

"If --incremental is passed, then the first revision dumped will be
a diff against the previous revision, instead of the usual fulltext."

so it's not gonna track where you've left off. you need a bit more
elaborate scheme. like storing last revision dumped in a text file, and
then using that value as a "svnadmin dump -r $lastRev /svn/repo >
/svn/dumpfiles/repo_dump.from$lastRev" or something like that.
