Backing up is important to me. Caveat: I'm kind of new in the Android world so take what I say with a grain of salt, and more seasoned people please correct anything I say wrong. This is just how I understand things. Here's the very ANNOYING thing with Android backups. To get the best backup options you seem to need to modify your phone, both rooting it and sideload enabling it. Only then can the backup tools do the most thorough job. That's pretty silly I think, hopefully in the future people will be able to get full benefits from new backup tools without 'hacking' into the phone. There seem to be a lot of different backup options that each do slightly different things. Right now I have MyBackup pro, Titanium Backup, and Rom Manager (which installed something that allows me to use Nandroid backups).
