Random Job Delay – Protected Item Schedule
This feature will delay the start of each job by a random number of minutes between 0 and the configured number.
If your Protected Item is scheduled to start at 9:00, and you set a 30 minute Random Delay, this would mean that the jobs would randomly start somewhere between 9:00 and 9.30. The start time is chosen on a per-job basis, so different delays between 0 and the maximum configured number will apply to each job.
If you have several backups starting at the same time, this means that instead of all jobs starting within seconds of each other, the load will be distributed approximately evenly over the configured number of minutes, which will reduce the peak CPU / Network.
If you have a site with 100 backups starting at 9:00 and use a 30 minute random job delay, this would result in the 100 jobs being relativly evenly spread over the 30 minutes between 9:00 and 9:30. Typcially the 100 jobs would start all at once.
A random job delay on all jobs starting at 9:00, for e.g. will help spread the load out over time; you could additionally change the start times of some of these jobs to help as well.
