Hi All, Relatively new OS X user (Yosemite), so this question might seem silly, please bear with me. I want to back up my MBP and want to know if it is possible without an external USB/HD? As a life long windows user, I used to store my files on a separate drive partition (eg. drive d or drive e) and have only windows loaded in drive c. In case windows crashed, or got virus etc, I would just re install windows in drive c and then have all my files. I know that with MBP, I probably do not need to worry about virus, malware etc. , but in case there is any start up problem, I wanted to know if I could create a back up in a separate place on my HD. I have read online about Time Capsule, but am not clear on how it works. Thanks in advance.
