Hello everybody, I would like to setup the following backup solution on my Mac: MacHD complete Backup to BackupHD round about every week. MacHD _semi-differential_ Backup to MemoryStick everytime I want to. What I mean with _semi-differential_ is: + I only want to store the different files onto the Stick in comparison to the complete Backup on the BackupHD. This is because the Memory Stick is only 2 GB of size. How can I achieve this by using rsync? Thanx in advance! Nils
