How often are scheduled backups taken, at what times and can this be configured?
対策
On Demand Recovery creates 4 backups a day which occur in all regions starting at the same time every 6 hours. The timings are 3:00, 9:00, 15:00, and 21:00 and all are UTC. Note that this does not mean that all backups start at exactly the same time but approximately at this interval.
Currently, this schedule is not user-configurable.
