So I was doing more backup-testing today.
When doing a "Full Backup" with subsequent health check enabled. The job became interrupted. However, the backup itself was successful. But it was the health check portion that failed/interrupted. This doesn't seem that it triggered the retry function.
I propose that the health checks are included into the retry criteria. But with the added granularity that when doing a retry, it only retries/continues the actual operation that failed. So it was the backup itself, then retry and continue the job from there. However, if it's the health check. Then it's unnecessary to redo the entire backup. And therefore only the health check needs to be redone.
If I'm wrong about how things work, then feel free to correct me. I'm only spit balling ideas that are based on my understanding of what I'm seeing.
Thanks
