Titanium Backup is a useful backup tool, which can back up and restore all your Android apps, even the protected ones. It doesn’t only save your apps data and their link on the Android Market, but also your phone settings, including Wi-Fi access point list.

You can download this app for free, but if you donate at least $3.99, you will get additional features such as scheduled backups and synchronize your backups to Dropbox. You think your phone is just fine now, but who knows what can happen later? Titanium Backup might save your life!
