What problem does this PR solve?

Issue Number: close #49517

Problem Summary:
Lightning job is failing intermittently after enable BR on prod clusters because of batch split failure. During the backup process, BR temporarily disables the schedulers for a period of 1-2 minutes. However, the Lightning job, which does not have a backoff mechanism, continues to retry the process for up to 5 times without pausing or spacing out the retries.

What changed and how does it work?

i am adding a exponential back off before each retry and now it will retry upto 930 seconds before if fails the job
