“I wanted to get Mozy up first. Is that one of the better ones to use?”
Carbonite and Mozy will both destroy your PC performance. Mozy also use to crash explorer.exe.
Both are crap. Both are crap solutions for backing up your PC.
Go to newegg.com or amazon.com or even bestbuy and buy a western digital passport Elements (not Essentials), and just drag your folders onto it when you want to backup.
When I had Mozy I used SyncToy to sync with a public folder on one of my PCs from all the others but with all the music and pics from the family PCs I was at 300 GBs - no doubt lots of dupes but Mozy changed their "unlimited" backup and I just did not renew - just shelved the public disk for the moment ...
I'd looked at various sync programs out there to automatically back up the various PCs (My Docs, My Pics, Outlook etc. but fire, flood, asteroid, etc. risks meant no offsite backup. Sigh! ;-)
