The UI recognizes only one default or current environment snapshot for a snapshot set. Use a consistent strategy for selecting a default snapshot:
Using this strategy, you create snapshots as point-in-time backups and do not make changes to the backed up environment snapshot. You make changes to the base snapshot.
Using this strategy, when you create a new environment, you do so with the intent of making it the new default environment snapshot. You do not make changes to the base snapshot or earlier environment snapshots.
The environment snapshot name must be unique within an environment snapshot set.
After you create a environment snapshot, you have the option to change the name of the environment. If you change the environment name, it is updated for every environment snapshot.
