    public abstract class BackupGroupRoot
    extends ImmutableObject
    Base class for entities that are the root of a Registry 2.0 entity group that gets enrolled in commit logs for backup purposes.

    The commit log system needs to preserve the ordering of closely timed mutations to entities in a single entity group. We require an UpdateAutoTimestamp field on the root of a group so that we can enforce strictly increasing timestamps.
