I don't see the purpose of this domain. Freeware and Backup don't really go together. You download freeware and you back up your files. Does anyone backup freeware? Perhaps it could work a lower quality brandable domain for a freeware site, but I'm not feeling it - definitely not for good bucks.
I see it as regfee for reseller and mid-high $xx enduser, assuming you can find one.
Hope this helps!
