As often as you can.

Heres a simple calculation. How long does it take to backup AND restore your data? How long would it take to recreate that data from the last time you backed up?

When it takes longer to recreate the data from the last time you backed up than the time it would take to back it up and restore it then it makes sense to do the backup

If it can't be recreated (customer data, logs, etc)? Backup as often as possible!

Daily.  I have it scheduled and it happens all the time without any interaction on my part.  Incremental backups daily and a full backup once a week.

"How often do I back up?" is a question only you can answer.

What are you doing with the data?  Are critical new items added regularly?  How regularly?

Do you cycle through several versions of backup or just make one?

What is it you are trying to protect yourself from?  Hard drive failure?  Theft?  Kid getting the computer infected?  Accidental deletion?  Floods?

Start to lay out your risks and what you do in response will be obvious.  For MOST people, that's hard drive failure.  I would say don't do it more often than weekly, just because you can get corrupted files from a failing HD (they don't always go out like a light) and spread that corruption to your backup.

If it's an actual drive image, make sure you know how to get it back, or have the boot CDs for the software you are using and know how to use them.

Backups for computers are just like the bug out SHTF plan. It will be very different depending on your situation.

How often depends on how important the data is - I do mine daily.  Really important stuff gets burned on DVD or CD also.
