To encrypt my SD Card, I use Cryptonite application. Although this app is under development, but it still does a pretty good job. In order to use this application, your android smartphone must be rooted. Using this application you can not only encrypt your SD card, but you can sync your SD card with Dropbox.

Taking Backup of Application (Root Required)

Using Titanium Backup Pro you can take backup or restore or freeze your applications. You can do the same for your data and market links. Titanium Backup Pro app also protects other apps on smartphone & the system apps. It can also take backup/restore external data on your SD card. You can have scheduled backups with this application.

Now your phone is fully encrypted. In order to get access to the phone, the thief must flash the ROM of your smartphone with another ROM. But this process will delete all your phone data, so your data will remain safe.

Do make sure that you regularly take backup of your data. You can get a new phone, but it is hard to get your own data.
