oandbackup
a backup program for android. requires root and allows you to backup individual apps and their data.
a working busybox and rsync installation is required at the moment.
instructions for obtaining an rsync binary can be found here: http://linux.wxs.ro/2011/08/05/rsync-your-android/
a busybox executable can be obtained from various sources. here are instructions for building it from source: http://mobisocial.stanford.edu/news/2011/02/compile-busybox-on-android-os/
unfortunately i cannot vouch for the quality of either web page.
an apk build of oandbackup is available on f-droid's servers: https://f-droid.org/repository/browse/?fdid=dk.jens.backup
