I have a 50GB TM machine backup. Am using a partition (of 128GB) from my external HDD, which is dedicated to TM backups and formatted with MAC's partition. Here is the really frustrating things; 1) I cannot encrypt it unless the WHOLE drive is one partition and the WHOLE drive is formatted with a MAC partition... WHY?!!! Why would Apple care if am using a partition, and even though the backup DOES work on it, why would they not encrypt it? Its plain stupid. 2) I said myself ok, I will do the backup first, and then transfer it to my other partition which has Truecrypt encrypting it. Well, the TM wont allow to transfer the backup from a MAC partition to a non-MAC partition. Why?! I understand the whole different partitions, etc, but its a backup, I would want to keep a backup of a backup.. So what are my options right now? am NOT going to buy an external HDD just to have an encrypted backup of my MBA, its a waste and its not that practical.. Also, I dont wanna leave my backup unencrypted, its stupid. Any solutions please?
