My iTunes library is quickly expanding passed the point of my 1 tb internal hard drive. This poses two problems, the obvious is not being able to expand it any further. The other is if I have a hard drive failure I'm going to be....well very upset to say the least. So what I want to do is move my iTunes library to an external drive, maybe 3 tb? AND I want a backup on another drive so maybe another 3 tb hard drive. What is the best and most reliable way to do this? Speed isn't anything too important since its just media. I have an iMac and an Airport Extreme. I was thinking about getting two 3 tb WD external hard drives and connecting one to the Mac and the other to the AE for back ups. Then occasionally manually backing up my library to the hard drive connected to the AE. Is this a good way of doing things? Are WD external drives reliable? Are there better options? I have NO experience with time machine however I have nothing I want to back up on the Mac aside from the iTunes library and a couple documents that I can easily manually manage. And to be honest sometimes Apples way of doing things is frightening to me especially when they start renaming things and using proprietary formats (remember like I said I have no experience with TM) so doing things manually is fine unless there is a better way. Thanks in advance guys!
