Properties
CreationWindow
Output only. Scheduled backups contain an externally consistent copy of the database at the version time
specified in schedule_spec.cron_spec
. However, Spanner might not initiate the creation of the scheduled
backups at that version time. Spanner initiates the creation of scheduled backups within the time window
bounded by the version_time specified in schedule_spec.cron_spec
and version_time + creation_window
.
