Hi, now that I have an iMac on order I am looking into my backup options. My iMac will have a 2Tb hard drive I have apple tv and have been seriously thinking about converting most (all?) my DVD films/shows to be in my iTunes library. This I am guessing will be between 600gb and 1.5Tb (depending if I go for just films or the tv series I also have). If I were to have over 2Tb held either on the iMac and / or an external hard drive I'm guessing that my backupnoptions will be: 1) don't back it all up, as I will still have the original DVDs; 2) use time machine and/or another software tool to backup to another external hard drive - but if over 2Tb required to be backed up then it would have to be something that compresses the data (don't think tm does this); 3) Use some 'cloud' backup service - but this will take forever and probably upset my ISP with the amount of data uploaded. What other suggestions do you have or currently use when you have a huge data/media backup requirement? Thanks, J.
