We had an interesting support call the other day that I thought might be useful to share.
The customer who called was using BackupAssist on multiple sites and using rsync jobs to backup from a number of Windows machines, to a central one running CWRsync. Everything was working well but there was some confusion as to how much space each job was taking up on the rsync server.
