Error in AAinfo logs:
Backups for all agents are scheduled to occur at the same time as, or near to the same time as the Nightly Jobs, which have a default schedule of 00:00
While the backup jobs are queuing, the nightly rollups also begin, which means the rollup takes priority, and the backup is skipped.
Change the backup schedule of your agents to make sure that they don't overlap with the nightly job rollups.
Change the schedule for your nightly jobs to run, which by default is at midnight every night, so that it doesn't overlap with scheduled backups.
Increase the concurrent jobs setting for transfers, to allow more backups run simultaneously, which will allow backups to complete sooner and possibly not overlap with rollup jobs.
* Increasing the amount of simultaneous transfer jobs on the core will impact core resources greatly. Please ensure that the core resources are capable of these increases before changing this setting.
