Unless you plan to pay for a dropbox subscription that supports your hard drive's amount of storage, no you cannot.Can I back it up to Drop Box? I'm trying to keep from buying another drive. I haven't upgraded the OS X 5.8 and it's now or never.
That's only your RAM, not your hard drive space.The Hardware Overview says I have 2 GB of memory. Do I need more than that to back up my computer? Sorry for being so uninformed. Drop Box says it offers 2 GB for free.
Even if you do happen to find one, you're generally better off going for a capacity that's at least double that of the amount you reckon you'll want to backup. A 320gb drive indeed sounds ideal.You need at least 200gb. They don't sell drives that small.
