I am looking to upgrade my iMac from 10.2.8 to Tiger and would like to back up my user information. Since I don't have an external HD, I was wondering if there are online sites where I can backup my user information which would be effective? My user info consists of approximately 58GB (some of which can probably be discarded). Any suggestions on whether that will work? Sites? prices? Is .Mac a possibility for this...not sure how much storage space they provide. Thanks!
