I would like to transfer my media i.e. iphoto library and itune library to my airdisk (attached to my AEBS). My imac which is ethernet connected and mac book and macmini which are wireless can then use the same library. However clearly the library must be backed up. Is it possible to configure time machine or for that matter can anyone recomend any other software to achieve this - time machine is set up to backup my imac.

Also if my libraries are on my airdisk will my apple, tv still be able to sync properly.

New to forum so hope this is enough information to enable someone to help but if not please ask.
