Drupal has become a big part of my job in the last year and a half. We have moved our public facing website over to Drupal 7 from a home-grown java based site. It has been fun to learn Drupal, teach other people how to manage their own pages, and learn how to administer the site. I've written a few modules here and there, but one of the biggest things I've done is set up our Intranet websites using a multi-site setup in Drupal.
There are plenty of great online backup services that give you a limited amount of free storage. The most well-known is Dropbox , which gives you 5 GB of storage for free. Google Drive gives you another 5 GB, and Microsoft's SkyDrive gives you 7 GB. Other less known places may give you more, such as ADrive with 50 GB or Shared with a whopping 100 GB.
