1) Copy the .bashrc file to Dropbox
cd cp .bashrc /home/praveensripati/Dropbox/Ubuntu/.bashrc2) Remove the original .bashrc file
rm -rf .bashrc3) Create a symbolic link to the file in the home folder
cd ln -s /home/praveensripati/Dropbox/Ubuntu/.bashrcNow, updates to the .bashrc file in the home folder will be automatically uploaded to Dropbox. And, lets say for some reason the hard disk drive crashes, then the .bashrc in the home folder can be restored using Dropbox data with Steps (2) and (3). The above mentioned procedure can be applied for other data like document annotations, desktop files etc.
