I have a late 2009 iMac with a 1tb hard drive running Snow Leopard.  Can I partion the hard drive and upgrade to Mountain Lion on one part and keep Snow Leopard on the other?  If not, can I partition my external back-up drive that I use for Time Machine to do the same thing?

iMac, Mac OS X (10.6.8)
