As the admin of salesforce.com, you are responsible for the integrity of the system for your organization. That means that you need to make sure that your system is up and running properly at all times. Sometimes it is out of your control because salesforce.com might be experiencing a rare problem. But for the most part, how accessible your data is and how it is viewed by your users is up to you.

A best practice to get in the habit off is to back up all of your data on a regular basis. This is very simple to do through the setup area in salesforce.com. Simply go to Setup-Data Management-Data Export and click the Data Export button.

In my organization, I make a back up of our data every Monday morning. I save a copy on the server (which is backed up every night) and I burn a copy on a disk to be stored off sight. This provides me a peace of mind. I am not worried about salesforce.com loosing all of its data. I am more worried about deleting data that we will need in the future. Having the back ups make it easy to get at the data if something were to be lost.
