When running Policy Server and CA Access Gateway (SPS), one might like
to know which machines is recommend to take a snapshot in order to
insure roll back in case of problem.
At first glance, it's recommended to take snapshots of the components
which are likely to have configuration and / or data change.
- Policy Store has changing data permanently;
- Policy Server and Access Gateway might have configuration changes
for customization, implementations, tuning etc.;
As such, it's recommended to take snapshots of all of them. More
important, as this operation is outside our product, we strongly
recommended to test the procedures in lower environment to insure that
the specific solution meets the Business needs.
