Hello all, I'm brand new to a mac computer, well since the imac Graphite!! And I'm wondering if Time machine is OS X's equivalent to system restore in Microsoft? Sounds a lot like it but I'm not sure to enable it or not, sounds like the first time around it could take quite a while to back up all my information. It Also seems that it could potentially take up a bit of disk space...I have a 320GB HDD but still i'm not sure if I want time machine taking up a lot of space. If someone could clarify these issues for me that would be great. It seems like there are some benefits and pitfalls to Time machine but I would rather be on the safe side....Just want to hear about it from a few of you before I do so! Thanks!
