I am currently running a dual-booting hackintosh with Windows 10 and OS X 10.10 Yosemite. OS X is backed up to an external drive with Time machine, but the Windows 10 side of things is not backed up. I want to fix that. I figured while I fix that, I should probably also remedy the fact that I have two other, older PCs that aren't backed up, as well as several external HDs I'd like to backup. I have some redundant copies of important files on various drives, but I'm looking for a more organized and streamlined system, and to backup the things I know are currently only in one location. I am willing to buy backup software for Windows, but what should I get? And should I just get one giant 6TB drive and backup all of my Windows computers and external drives to it by manually copying and dragging files/folders, or is there a better way? Thank you for the help!
