The UI recognizes only one default or current project 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 project snapshot. You make changes to the base snapshot and continue to run jobs using the base snapshot project only.
Using this strategy, when you create a new project, you do so with the intent of making it the new default project snapshot. You do not make changes to the base snapshot or earlier project snapshots. The latest snapshot is the one used to run jobs.
The project snapshot name must be unique within a project snapshot set.
After you create a project snapshot, you have the option to change the name of the project. If you change the project name, it is updated for every project snapshot.
