I would like to know, is thedefault persistency mechanism of pier
when we start the plain default seaside image?
Open an explorer on the kernel of your Pier instance:
PRKernel instances explore
Select the kernel and evaluate:
self persistency: PRImagePersistency new
From then on it should automatically take snapshots every hour when
something changed. Also it automatically backups the images.
Pay attention not set the image persistency while loading code or
while doing development. Unfortunately saving the image while code is
compiled can screw up your changes.
