I just got a bigger SSD drive for my mid 2012 MBA and I wanted to backup my data (ios device syncs, documents, etc.) however, I don't need to save my program prefs or anything like that as I don't need those and want to do clean installs on my new HD. I don't necessarily need a HD clone as much as a data backup. What's the best program to use for that? Also, would you recommend me updating to Mavericks before swapping hard drives OR do the upgrade once the new hard drive is installed? Thanks MR!
