How often should a back up be done?

This is one of the hardest question I get asked by a client. Mostly because there are so many variables from one client's computer to another.

I respond by asking three question, that will answer their question.

1. What is the longest period between back up can you feel safe in rebuilding your business?
2. What is the shortest period you feel would be needed between back ups?
3. Which time period between the two would you feel most comfortable in backing up your computer's data.

Something to think about: A complete back up on one media is usually not enough. One full back up should be kept off site and in a secure place. This is insurance to protect you in case there is a disaster i.e. fire, flood, earthquake or some man made one.
