I recently crashed my hard drive and now looking to buy an external hard drive to use with time machine. I have read so many articles in regards to this that now I am confused. Hard drive is 80 GB and have 51 GB of free space. My important files are my music and photos. I want something easy to use. Once everything is stored in an external hard drive, do I have to make a bootable disk to start my mac?

iMac (27-inch Late 2009), OS X Mountain Lion (10.8.2)

    As you have a 27-inch Late 2009 iMac, you have got a 1 or 2 TB hard drive. As you have a big hard drive and a small amount of free space, get a 2 TB hard drive minimum that you can connect with USB or FireWire (I recommend FireWire because it's faster).


    The default way to back up your Mac is using Time Machine. This will create complete backups of the hard drive onto the external drive. However, Time Machine doesn't create bootable backups, and you may need it if your hard drive gets damaged, so you should use Carbon Copy Cloner or SuperDuper on a different partition or external drive.


    Also, I can see that your most important files are your music and photos. As you have a small amount of free space, you can delete some folders from the Time Machine backup to save space onto the external drive: open System Preferences > Time Machine > Options, and add folders that you don't need to Excluded Items.
