Delay values range from zero to the specified maximum delay value, and are determined according
to the chosen distribution method.
The delay value for each machine is determined when the policy is deployed to the machine, and
remains the same until you edit the policy and change the maximum delay value.
The conditions, if any, will be checked at the task's actual start time on each machine.
The following examples illustrate this setting.
Example 1
Suppose that you are deploying a backup policy with the following schedule to three machines:
Run the task:
Daily
Once at:
09:00:00 AM
Distribute start time within the time window
Maximum delay:
1 Hour(s)
Distribution method:
Random
Then the task's start time on each machine may be any time between 09:00:00 AM and
09:59:59 AM—for instance:
First machine: Every day at 09:30:03 AM
Second machine: Every day at 09:00:00 AM
Third machine: Every day at 09:59:59 AM
Example 2
Suppose that you are deploying a backup policy with the following schedule to three machines:
Run the task:
Daily
Every:
2 Hour(s)
From:
09:00:00 AM
Until:
11:00:00 AM
Distribute start time within the time window
Maximum delay:
1 Hour(s)
Distribution method:
Random
Then the time of the task's first run on each machine may be any time between 09:00:00 AM and
09:59:59 AM; the interval between the first and the second run is exactly two hours—for
instance:
First machine: Every day at 09:30:03 AM and 11:30:03 AM
Second machine: Every day at 09:00:00 AM and 11:00:00 AM
Third machine: Every day at 09:59:59 AM and 11:59:59 AM
