this is - most probably - due to the fact that you changed your backup
definition after the last full backup. Even though you are backing up the same
files on the client, for BackupPC it's a different share and thus different
files now. Run a full backup and see if the problem goes away on subsequent
incrementals [but first see the notes on TopDir below].

That is strange. It would seem that you are backing up significantly more than
on your first full backup - even if pooling is not working.

ftp:// ? Are you serious?

That one is simply wrong and would probably explain why pooling is not
working. Which version of BackupPC did you say you are using?
Don't try to change TopDir in your configuration file(s) - least of all in the
host specific configuration file (then again, wouldn't it simply be ignored
there?). Use a symbolic link or a bind mount. See
http://backuppc.wiki.sourceforge.net/change+archive+directory ...

The RsyncShareName seems to be missing ... '/', right?

See the note on TopDir above.

Well, it isn't, is it? /home/madams is not even in BackupFilesOnly. It would
seem that something got mixed up, but perhaps it's just that I didn't look at
config.pl. Could you please include the correct config files? :)
