The UI recognizes only one default or current selector snapshot for a snapshot set. Use a consistent strategy for selecting a default snapshot:
Use snapshots as backups. Make changes only to the base snapshot. Do not make changes to the backed up selector snapshot.
Each time you create a new selector snapshot, make it the new default selector snapshot. Do not make changes to the base selector snapshot or earlier selector snapshots.
The selector snapshot name must be unique within a selector snapshot set.
After you create a selector snapshot, you have the option to change the name of the selector. If you change the selector name, it is updated for every selector snapshot.
