BugDave writes: In Apple's Mac OS X Leopard guided tour a new feature called Time Machine is previewed. This feature will allow the user to have a constant backup of their system to a separate drive every hour. A user can empty the trash and recover it's contents over a week later. My question is how will the secure empty trash command come in to play with Apple's Time Machine? If a user invokes the command will the finder instruct a 7-pass erase to all the backups of the file as well as the file's existence in Time Machine or will the finder just delete the files locally only for them to be recovered again?
