I have an external drive hooked up to a Mac Mini. That external drive is where I've been keeping my Time Machine Backups, not just for the Mini, but also for my MacBook Pro (OSX Lion). A friend recently showed me that I can wirelessly connect the MBP to the Mini, and even access the external drive remotely. This is great, as it appears that I can do my MacBook Pro Time Machine backup wirelessly, rather than plugging it in, which is what I've been doing. However, when I start the Time Machine Backup, it's attempting to create an entirely new Time Machine Backup (230+ GB), rather than just freshening up from the existing profiles. This just started when I attempted the wireless backups. Any ideas on how to have it recognize its existing backups/?
