Scenario: Your Catalog backups are not running. You check the jobs and these are hung with the error below.
Limit has been reached for the logical resource %MyServer%.NBU_CATALOG.MAXJOBS
Google and Symantec’s forums weren’t giving me much. I checked disk space, the policy, the schedules, the media and anything other setting I could find.
Solution: The solution is obvious in hindsight. Netbackup only allows one Catalog job to run at a time.
Queried my history and found a hung Catalog job. Terminated the old job, ran a manual backup and all is going again.
