Apologies in advance if this question has been addressed specifically, although threads I've read only touch upon it and even raise new questions. I'm considering Time Capsule and/or another option to accomplish the following: 1) Backup data from a MacBook. 2) Serve as extra storage for media files. 3) Serve as a router for media files to said MacBook and also a conventional flat screen television (probably via Apple TV). So, some questions: A) Since the MacBook would not have the capacity to act as a 2nd backup to Time Capsule, necessity of a separate external hard drive (sized same as Time Capsule) in that capacity? B) If separate external hard drive connected to Time Capsule, will Time Machine backup both at same time, so they mirror one another? If not, does separate external hard drive have to be backed up manually (and then Time Capsule not really so automatic)? C) Will files deleted from the MacBook be automatically deleted as well in Time Capsule (so that backup files reflect ONLY those on MacBook at any given time, and not just be forever added to)? D) Is Time Capsule really necessary? Would Time Machine be just as happy (and easy to set up) using Airport Extreme and 2 (two) separate external hard drives? E) Will Time Machine conflict with media files? On an unpartitioned disk (whether Time Capsule, or not) could it ever overwrite and destroy stored media files (stored only there and NOT on the MacBook)? F) Is Time Capsule or Airport Extreme suitable for watching video on a MacBook via WiFi? A flat screen television could presumably be hard wired, and no problem. But is it practical to expect that a movie downloaded from iTunes (or the mirror image of a DVD) would be just as accessible (like how would iTunes/DVD player find it, if not on the MacBook) and viewable (is the transfer rate really sufficient) whether the file residing only on the MacBook, or only on Time Capsule? G) Will Time Machine conflict with other WiFi needs? For instance, if browsing the internet or using Time Capsule as a router to watch a movie via WiFi will Time Machine wait for another time to automatically backup? Or will it insist on butting in, and myself happier backing up everything manually? Sorry if this seems convoluted, but I wished to touch upon specifics of a basic question. Namely, an easy way to safely backup a MacBook, and remove some movies from it (due space limitations) yet easily view them. Thanks.
