Cloned from launchpad blueprint https://blueprints.launchpad.net/heat/+spec/stack-snapshot. Description: When we have implemented volume snapshots, a next step could be to allow snapshot of the entire stack, ie save the resolved template at a point in time, along with all resource metadata, and volume point-in-time snapshot, then potentially use a similar method the one we currently provide for on-failure rollback to allow rolling back to a previous stack snapshot. Specification URL (additional information): None
It is known that sometimes updating of a stack would fail. Knowing that, trying to restore from a snapshot might also fail after an update failure. A user might want to be able to update a stack but to be able to return to a previous state if the update fails. Considering this logical assumption of a requirement and this upstream bug [1], its hard to verify this feature until reverting to a previous state works properly.
