So I've acquired a new Win8 pc and I'm contemplating my back up scheme. Previously, I was using Crashplan for offline back up. I'm thinking about skipping that and using SkyDrive to back up my photos & doc, because it's free and (sort of) built in. My music is backed up via Amazon's cloud music service (and works beautifully). But I'm not sure about a local back up. I have my various file on a partition on hard drive and was planning on mirroring that partition to a WD Passport drive. But now I'm wondering about using File History. If I understand correctly, I need this on anyway, to do auto backups of, say, Word docs as I'm typing? But I could be wrong ... And is it saving multiple copies of files? I don't really want that. In short, I'm not sure if the new File History is a useful alternative to running disk mirroring software. What do you think, sirs?
