google.protobuf.timestamp_pb2.Timestamp
The backup contains an externally consistent copy of
``source_database`` at the timestamp specified by
``version_time``. If the
`CreateBackup][google.spanner.admin.database.v1.DatabaseAdmin.CreateBackup]`
request did not specify ``version_time``, the
``version_time`` of the backup is equivalent to the
``create_time``.

`CreateBackup][google.spanner.admin.database.v1.DatabaseAdmin.CreateBackup]`
request was received.
