I loved BitTorrent Sync but it's so glitchy about syncing. I can't figure it out. Did you have any issues with it? I am using Mac (Mavericks) on both computers I was syncing. I only use BitTorrent Sync / DropBox for moving items from my work computer to my laptop and I need to know that if I drop a folder in there at 5pm when I'm racing to class, it'll be there when I get home. After about 4 times of not having a needed file with me and having to remote in to make a tiny change or grab a PDF I created at work, I got sick of it. Dropbox never fails Google Drive is also now offering insane prices (15gb free, 100 GB $1.99, 1 TB $9.99, 10 TB $99.99, 20 TB $199.99, 30 TB $299.99) but if privacy is a concern Google may not be the best place. Also, there have been horror stories about people getting locked out of their accounts, etc. Always have your work, especially important stuff, doubled up. For big projects I often have a copy on my laptop, on my work computer, on the work server, and in my DropBox.
