Just out on the Market (search for Sprite Backup and scroll down to 2.1 Beta), this backs up your Android data on SD card or your Dropbox account. As far as I can see, it's similar to RerWare's Backup Pro, although it doesn't appear quite as configurable. The beta expires 7/1/2010. If you're not alread a Dropbox user, you can use this referral link to sign up: https://www.dropbox.com/referrals/NTUzMjk2MzM5, or any of the numerous links in this thread: http://androidforums.com/android-applications/68894-dropbox-referral-thread-only-post-them-here.html
The splash screen says "We've been working with our new friends at Dropbox to allow you to store your backup files on their servers," and winds up saying, "even better still, is that Dropbox offer (sic) 2GB of online storage for free!" If I'm not mistaken, though, that's what Dropbox offers as any new user. What's more, when you use a referral link, but the referrer and the referred get another 250 MB as a bonus, so I'm not sure what the enticement is here. Oh well.
