Dropbox: Painless and Free Backup

“At home, you use Linux. At work, you use Windows. How do you
share files between them? If you said, “USB drives” or “CDs” or
“DVDs” there is a better way: Dropbox. Dropbox provides you with
the ability to sync files between computers via a daemon.
Additionally, they’re available on the web for those times when you
don’t have physical proximity to one of your computers but you
still need access to your files.

“Dropbox also provides you with a reliable backup solution. In
its simplest implementation, you have your local copy and an online
copy of every file in your Dropbox folder. In more complex
scenarios, you can keep files synchronized between several
computers and an online copy.”
