If your server is running unix (or Linux), this should do what you want:

  "UnixProcess saveImageInBackgroundNicely"

The image will be saved with a time stamped file name. The save is done
in a lower priority background OS process that should have minimal
impact on your server image. You could for example set it up like
this:

  [[(Delay forSeconds: 4 * 60 * 60) wait. "wait 4 hours"
  UnixProcess saveImageInBackgroundNicely] repeat] fork

This requires the OSProcess package from SqueakMap.

I suspect that you could fill up a disk drive pretty quickly like this,
so you'll need to come up with some way to purge out the old image
files. Maybe someone who is doing this already can suggest a good
approach.
