Incremental backup job doesn't run and is set to 'Superseded' status if full backup job with no recurring schedule is suspended after it is performed
If a full backup job with no recurring schedule is suspended after it is performed, the subsequent incremental/differential backup job does not run and the job status is set to 'Superseded' when the scheduled time comes.
The job can be suspended via BEMCLI with the following commands:
BEMCLI> Get-BEJob "Job-Name-Full" | Start-BEJob -Confirm:$False | Wait-BEJob ; Get-BEJob "Job-Name-Full" | Suspend-BEJob
Please be noted that this issue reproduces only when a full backup job does not have recurring schedule.
