Modify a snapshot schedule
Any changes to a snapshot schedule are applied only to snapshots that are generated after the changes are made. Schedule changes do not affect existing snapshots.
About this task
If you modify the snapshot alias of a snapshot schedule, the alias is assigned to the next snapshot that is generated based on the schedule. However, the old alias is not removed from the last snapshot that it was assigned to. Unless you manually remove the old alias, the alias remains attached to the last snapshot that it was assigned to.
