Not as often as I should is the answer.
For the web site I normally regard the on-line copy as the backup. That isn't always reliable -
I had a lot of photos on a web based hosting service and on hard disk - no problem two copies.
PC crashed and I lost the disc but didn't bother to copy them all back from the hosting service
Hosting service went bust and was taken down without warning.
