Backup ReadyNas to ReadyNas with rsync and exclude lists

This thread contains the closest to a solution that I've found. but unfortunately, now that the /frontview/bin/backup file is compiled, I'm unable to take advantage of the advice here. I was wondering if anyone has alternative methods for passing parameters along to the rsync backups?

My specific error is this.

uid 5234567890 (-1) is impossible to set on "/USER/FOLDER/FILE.TXT"

From what I've read, this error comes from the UID being too large for rsync to handle. The large UID I believe comes from having user shares auto-created from Active Directory users. There are recommendations to pass the "--fake-super" parameter on to the rsync command to avoid this error. I need to avoid the error so that my backup status can come back as successful.

I'm running RAIDiator 4.2.19 on a ReadyNAS 2100.

Any suggestions would be most appreciated.

UPDATE: By the way, the remote/source of the backup job is a Windows 2003 box running cygwin.

Thank You
