Just to clarify.. I'm wondering if you're talking about some sort of 
automated setup where
the image is flushed out (I don't know how pier stores its data -- I'm 
assume it's stored in
the image directly) and then saved on a regular basis (perhaps nightly) 
with a time/date
tag appended to the name to allow easy retrieval of earlier versions of 
the image (e.g. non
corrupted)..

I was wondering this as well, and I'd be tempted to call this a form of 
checkpointing
of the image and I would think that there must be an easy way to do this 
in Smalltalk
since this issue doesn't quite apply to most other non-image based 
languages.. This
also isn't specific to Pier as it can easily happen if I've got a 
Seaside app that writes to
a database that lives within the image -- I'd certainly want to 
checkpoint that database image
on a regular basis to ensure I lose nothing if the image is corrupted 
somehow..  Anyway,
I guess you could setup things somehow (triggered off a timer?) to write 
out your image
(I'm assuming there's a way to programmatically force an image save, but 
I've got no
idea there) on a regular basis and to specify the image name to save 
under..

Anyway, not sure if that is what the OP was looking for..
