flexbackup

Exclude is really designed for individual files that may occur anywhere,
not for specific paths where you want to exclude all files under that path.
Use prune instead. For your example, if your backup set was baching up
from the root of the volume (i.e., "/"), then the prune term would be:

$prune{'/'} = 'ftp/anonymous/media';

Note that, with prune and exclude that the terms are regular expressions,
not filename globs. Furthermore, flexbackup does some manipulation of the
terms to come up with the final regular expressions that is somewhat
unintuntive. I've created enhanced documentation that explains a great
deal about prine and exclude. Email me if you want it.
