If possible, let your job run at, say 11 o'clock p.m. or like 10 minutes before midnight. It could 1. move last days backup /backupdir/current.bak to /somewhere-else/backup_thisday.bak 2. start new backup into /backupdir/current.bak Then let BackupPC only backup /backupdir. That way you get your local history of backups and provide BackupPC the opportunity to use rsync's differential transfer optimizations.
