 ### What is the maximum delay I can expect in backup start time from the scheduled backup time I have set in my VM backup policy?
 The scheduled backup will be triggered within 2 hours of the scheduled backup time. For ex. If 100 VMs have backup start time scheduled at 2:00 am, then by max 4:00 am all the 100VMs will have backup job in progress.
