When a Veeam backup job was in a running state (Starting, Working, Postprocessing) and the agent plugin reported no result yet, the check previously defaulted to OK. On the next check cycle, once the job completed with a failure, the state changed to CRIT — only to flip back to OK on the following retry when the job restarted. This caused a flapping pattern: OK -> CRIT -> OK -> CRIT.
Starting with this release, the check preserves the previous check result while the job is still running and no definitive status is available. This prevents false OK states and eliminates the flapping cycle.
